Borussia Dortmund and Bayern Munich will contest the first all-German European Cup final after their defeat of the Spanish giants, while Chelsea's chances of lifting silverware this season remain alive as they look forward to the Europa League final in Amsterdam.

Further afield, and Ye Wo-cheng became the youngest golfer on the European Tour at the age of 12, Sam Warburton became the youngest captain of the British and Irish Lions while the rugby World Cup will be staged at nine football stadiums in 2015.

They all feature in the sport pictures of the week...

After Manchester United became Barclays Premier League champions, the Bundesliga teams took centre stage. Bayern Munich and Borussia Dortmund's batterings of Barcelona and Real Madrid have almost certainly guaranteed a first ever all-German European Cup final.

The sun was out for a buoyant London Marathon, which paid tribute to those who suffered in Boston last week, while the Red Sox paid their own respects at Fenway Park.

And from America to Australia, and beyond, we go for the sport pictures of the week...

Maria Sharapova is the face of Nike, Tag Heuer and whatever tennis tournament she features in, and now she can add sports cars to her list after being unveiled as Porsche's brand ambassador.

Sharapova, 16, was at the Porsche Museum in Stuttgart, Germany, standing tall alongside 911s, hogging the limelight in front of a Cabriolet and sitting in the driving seat of a Spyder.

That Porsche, traditionally dominated by male buyers, chose Sharapova to be the face of its company for the next three years is testament to her her allure.

Sharapova, the No. 2 women's tennis player in the world, makes about $20 million a year in endorsements, more money than any other female athlete.

Novak Djokovic ended Rafael Nadal's supremacy at the Monte Carlo Masters in today's final and underlined why he is still the man to beat.

Nadal had won the last eight tournaments in the principality - including beating Djokovic in the 2009 and 2012 finals - but the Spaniard was left stunned when the Australian Open champion comfortably won the first set, having raced into a 5-0 lead.

The world number one twice battled back from a break down in the second set to take it to a tiebreak before wrapping up a 6-2 7-6 (7/1) win in a little under two hours.

While Nadal is still working his way back to his best form after returning from an eight-month lay-off due to injury and illness in February, the manner of the Serbian's victory - particularly his first set performance - left many gobsmacked.

"Congratulations Novak, what you're doing is just amazing. Congratulations to you for winning my favourite tournament," he said at the presentation ceremony.

"Thank you very much all my team for supporting me, the last year was especially hard for me so without them and without the support of all of you - all the messages I received during that time - was very positive energy for me."

The left-hander had last tasted defeat in this competition in 2003, which may have ensured he was the favourite against one of his greatest foes.

Bubba became "Blubba" again as 2012 US Masters Watson turned on the waterworks when asked to explain the tracks of his tears at last year's Augusta win.

In victory or defeat, countless sportsmen have shed tears throughout the decades. It's more than a game.

Andy Murray was the master in Miami as he beat David Ferrer in the Miami Open final while Serena Williams took the ladies' title. The Champions League last eight resulted in Paris sizzling as PSG drew 2-2 with Barcelona while Real Madrid produced a gala performance against Galatasaray.

Tottenham, Chelsea and Newcastle meanwhile competed in the Europa League and there are American pictures galore in the pick of the week's snapshots...

British number one Heather Watson has been ordered by doctors to rest after she was diagnosed with glandular fever.

The 20-year-old, who reached the third round of the Australian Open in January, has struggled for form this season and lost in the first round of the recent tournaments in Indian Wells and Miami.

The star announced she was taking a break from the game recently following her defeat by Ayumi Morita in Miami - in a match she had led comfortably - before reversing the decision 24 hours later, claiming she was simply been disappointed at losing the match.

But she headed home to Guernsey and pulled out of this week's tournament in Charleston, and blood tests have confirmed Watson is suffering from glandular fever.

She told the Lawn Tennis Association: "I had to do some blood tests after Miami and the results have shown that I have traces of glandular fever in my system.

"There is no prescription for this other than complete rest but the good news is that the doctors have told me I am at the tail-end of the fever. This means I have been trying to compete through the symptoms for some time."

Glandular fever is reasonably common in tennis players. Roger Federer suffered from it in 2008 while Justine Henin and Andy Roddick also got through it and resumed their careers relatively quickly.

But others have not been so fortunate. Mario Ancic was never the same player after contracting the disease while two-time French Open finalist Robin Soderling admits it may have ended his career at 26.

Watson is relieved to have a diagnosis, and said on www.lta.org.uk: "I have been struggling with both training and playing matches and felt so tired and exhausted for months but now that the doctors have found the cause of this it explains everything that has been happening to me physically and mentally.

"I am actually relieved to know what is wrong so that I can get myself on the mend. I hope to recover as soon as possible by resting my body and getting lots of sleep.

"I already feel better from being at home for a week and am looking forward to getting back on tour soon."

When Watson returns will depend on her recovery but it now seems very unlikely she will be available for Great Britain's Fed Cup tie in Argentina later this month.

The world number 40's absence would be a major blow for Judy Murray's team as they aim for promotion to World Group II.

Iain Bates, head of women's tennis at the Lawn Tennis Association, said: "First of all, get well soon, Heather, from the whole team.

"We all know she'll bounce back better than ever. Heather's focus will be on her recovery and we will do whatever we can to support Heather and help that process."

The tennis landscape has altered considerably over that last 12 months. Andy Murray will wake up on Monday to confirmation of something we've long known: he is currently the second best tennis player in the world. For the first time in his career he is ranked higher than the great Roger Federer, with his eyes now firmly set on overhauling Novak Djokovic to become world number one. It's a fantastic thought for any British tennis fan.

It's also the first time in 10 years that neither Federer nor Rafael Nadal will will feature in the top 2 of the world rankings. Murray and Djokovic are, for now at least, the dominant forces in the men's game. The Federer-Nadal duopoly that was once so formidable has finally made way.

This was Murray's second Miami Masters title, having first won it back in 2009, but it was far from a vintage performance as he struggled to a 2-6, 6-4, 7-6 (7-1) win over David Ferrer in 2 hours 45 minutes. Usually it's his brilliance and ingenuity we marvel at, but this win was all about his character and ability to dig in when his A game failed him. Ferrer, one of the game's finest fighters, was outfought. Just.

It was a very strange final, indeed. The majority of the match was strewn with errors, before the utterly compelling closing stages made sure it will be remembered for a long time. After trading the first two sets, the match moved into a decider, where neither player seemed to want to hold serve (there were six successive breaks) as momentum ebbed and flowed and the drama became almost unbearable. Murray saved match point, surviving a Hawk Eye call, before forcing a tiebreak which he won won comfortably.

Speaking to Sky Sports afterwards, Murray said:

It was a very tough match and it could've gone either way. We both struggled physically but thankfully I had enough to come through.

David (Ferrer) is one of the best players in the world and it's always incredibly tough playing him. He could've won the match.

It was a strange match. I just managed to fight well in the end in incredibly difficult conditions.

That sort of match a couple of years ago I probably would have lost. I was up a break three or four times in the third set and kept letting him back in through some loose shots.

I tried to keep fighting, chased down every ball, made it as hard for him as possible. There was a lot riding on the match and I was glad to get through in the end.

The number 2 ranking not only brings with it recognition of Murray's improvement and success over the past year, but also the practical benefits of more favourable draws in upcoming tournaments, something Ivan Lendl, Murray's coach, was keen to point out in an interview on Friday.

The Djokovic-Murray rivalry was undoubtedly the game's biggest draw last year, and that could well continue this season, although, the return of Nadal certainly adds an extra dimension to the tussle at the top of the game, and only a fool would write Federer out of contention.

The challenge for Murray now, of course, is to perform better on clay, starting in Monte Carlo, the next Masters 1000 event, which kicks off in two weeks time. If he really has aspirations of being the world number 1, he must start competing at the same level on the clay as he does on grass and hard courts. Djokovic, Nadal and Federer manage it, so Murray must, too. To become world number 1 in the most competitive era of men's tennis ever is an incredibly difficult task, but Murray knows that better than anybody. The amount of blood, sweat and tears that's gone into his rise to the number 2 spot is proof of how tough it will be but he has the game and, crucially, the belief he can do it. The next few months look set to be very interesting ones for Britain's Andy Murray.

Andy Murray has defeated David Ferrer in the Miami Masters final to move above Roger Federer and up to number two in the world rankings.

The Scot recorded a 2-6 6-4 7-6 (7/1) victory over the Spaniard, coming back from match point down late in the third set.

Murray was far from his best for long periods of a gruelling encounter, losing the first set and seeing his own serve frequently broken by his Spanish opponent.

But after two hours and 45 minutes, he dismissed Ferrer in the tie-break to lift the trophy for the second time in his career.

Lauren Davis' third-round defeat to Alize Cornet at the Sony Open stung - literally - when a wasp pricked her.

Ignominiously, the 19-year-old was stung on her backside during her encounter with France's Alize Cornet, and she then drew blood on her thigh due to an errant fingernail.

Davis was adamant the incident did not contribute to her 2-6 6-3 6-2 loss but she and her opponent both physically suffered in the stifling Floridian humidity.

On-court temperatures soared into the 90s and both players left the court in wheelchairs after their three-set encounter.

Rafael Nadal's coach and uncle Toni has branded Christophe Rochus an "imbecile" over comments he made regarding the French Open winner and doping.

Nadal has made a storming comeback after seven months out with a knee injury, beating Juan Martín del Potro in the Indian Wells Masters on Sunday, less than a month after his victory at the Brazil Open.

And following his nephew's success, Toni Nadal spoke out against Rochus.

He told puntodebreak.com: "Apart from being an imbecile, Rochus is just rude. He is a real imbecile because if you knew something, I think it would be right to say it. But knowing, as I think he must know, that Rafael has never taken anything in his life and never will, I find it incredible that an idiot like this can say what he said."

Rochus said in January: "The anti-doping controls are not rigorous, in my opinion, and they don't really prove anything.

"As for Rafa Nadal, they're just rumours, but everyone's asking the question: How can he be so strong at Roland Garros and then just a month later, apparently he's unable to play? That's what makes it sound suspicious, but we don't have any proof, of course."

He added it was "inconceivable" that players can play for five hours in hot temperatures and "still run like a rabbit" the next day. US Open champion Andy Murray described the 34-year-old's comments as "far from the truth".

Asked about anti-doping measures, Toni Nadal replied: "Anti-doping controls should be public and transparent, but I'm against the way it's carried out.

"I find it incredible and unpleasant that a professional player, just because he plays sport, can be treated like a criminal. Nevertheless, I am in favour of them imposing the strictest possible controls, because that's good - but with different ethics."

Caroline Wozniacki is still yet to win a Grand Slam and has lost her number one status, but she is making it up to her male fans by modelling her new underwear range.

The 22-year-old Dane calls the collection "this is me" and stressed the importance of underwear.

"For me it is very important to wear a good set of underwear," Wozniacki explains in the promotional video.

"It is just important that you feel comfortable, it looks good, it matches your clothes and makes you feel feminine and sexy as well.

"I have my name on an underwear collection – it is just fantastic."

We can see why boyfriend Rory McIlroy may have abruptly quit the Honda Classic.

Heather Watson plans to take a break from tennis after admitting to feeling "burnt out" following a second successive first-round defeat on the WTA Tour.

The British number one says she needs to "find my game again" after crashing to a 6-1 5-7 4-6 loss to Japan's Ayumi Morita at the Sony Open in Miami yesterday.

The result continued a miserable sequence for the 20-year-old from Guernsey, who bowed out of Indian Wells at the hands of Irina-Camelia Begu and has not won a match since climbing to a career-high 39 in the world rankings at the end of February.

"This year I've been going a bit too long so I'm a bit burnt out," Watson said in quotes reported on the BBC Sport website.

"I've been thinking about it for a while now and I'm definitely going to take a break from tennis."

Watson's loss to world number 50 Morita came despite taking the first set in style.

She was unable to maintain her level, however, and managed just one break against two for Morita in each of the next two sets as the Japanese wrapped up victory in two hours 45 minutes.

"I was looking at the stats and I actually won more points, but that can happen in tennis," Watson said.

"It really hurts. I think I just need to find myself, find my game again."

She added: "I was playing really well, probably the best I've played this year, and I think I lost my concentration a bit, but that was enough for her to gain some confidence and step forward, and it kind of pushed me back and I started to play a lot worse.

"I still tried to fight but it just wasn't good enough, I wasn't aggressive enough."

Watson started 2013 in good form, reaching the third round at the Australian Open and the quarter-finals of the hard-court event in Memphis, while last-16 appearances in Pattaya City and Auckland also helped her to her best ever position in the world rankings.

Although Watson did not go into specifics over how long she intends to be away from the sport, it seems unlikely that she would want to skip the French Open starting on May 26 or the grass-court season which follows and culminates with Wimbledon at the end of June.

Andy Murray accused Carlos Berlocq of gamesmanship after becoming exasperated by the Argentinian's grunting after his fourth round win at the BNP Paribas Open.

Murray won the match 7-6 (7/4) 6-4 to progress through to the quarter-finals in Indian Wells but the Scot was far from impressed by the conduct of his opponent.

After Berlocq had criticised Murray for taking too long between points, the world number three responded by complaining to the umpire about the noise the South American was making.

Speaking after his victory, Murray suggested Berlocq was deliberately loud at key moments.

He told the BBC: "It was extremely, extremely loud, more than what I have experienced from any other player on the tour.

"It's like sometimes silence and then it comes out of nowhere. It's a bit of a shock.

"That's what I don't understand. To go from nothing to the loudest grunt you can do. It makes no sense.

"When I have been on the court or off it, it's never been something I have found to be really that off-putting.

"But if it's going to be suggested that I am using gamesmanship by taking too long, then you can't be making noises like that on the court. I haven't experienced it like that before."
