Five Exciting Youngsters Who Will Look to Make a Name for Themselves in Brazil

World Cup fever has officially taken hold and with only nine days to go until one of the most anticipated and exciting sporting events in the world, who can blame us?

In the past, many a player has burst onto the scene during a World Cup tournament and gone on to make a name for themselves. Hopefully this year will be no different.

Most of us armchair fans will already know of the more famous youngsters who will be playing in this summer's tournament - the likes of Raheem Sterling, Koke, Neymar, Marco Veratti, Julian Draxler and the like.

For now, however, let's forget those who we are already familiar with and take a look at some youngsters who aren't as well known as those listed above, but who will see this summer's tournament as a chance to introduce themselves to the world on the biggest of stages.

5. Joel Campbell

The on loan Arsenal man could be instrumental for Costa Rica in a side that lacks star quality. The team will have a tough run of games against England, Italy and Uruguay and will need to score goals if they are to pull off a miracle and progress to the knockout stages. Along with Bryan Ruiz, Campbell may be the man to do just that.

Stranger things have happened and if the Olympiakos man can link up with star man Ruiz and rekindle something of the panache that saw him score a fantastic goal against Manchester United in the Champions League, then Costa Rica may just be in with a shout.

4. William Carvalho

Carvalho's work as a defensive midfielder for Sporting Lisbon has earned him excellent reviews this season after helping a side that has recently underachieved to get within touching distance of the Portuguese league title.

The likes of Manchester United and Internazionale are said to be interested in securing his services during the summer, displaying just how far he has come over a short period of time.

The national side are similarly underachievers and Paulo Bento will be hoping that Carvalho can slot into midfield and provide defensive cover. This would allow the likes of Nani and a certain man called Cristiano to attack with a lot more freedom.

Although Portugal are underdogs for the tournament, anybody who helps Ronaldo to thrive up top could potentially be instrumental towards the business end of this summer's tournament.

3. Son Heung-min

South Korea are not expected to make any lasting impression on World Cup 2014, though if they do you would expect that Bayer Leverkusen's Son Heung-Min will have had something to do with it.

Nonetheless, the knockout stages are not necessarily beyond them as it is entirely conceivable that they could progress from a group containing Algeria, Belgium and Russia.

Heung-min is usually played off the striker or out wide and on his day can be a lethal finisher. He plays second-fiddle to Stefan Kiessling in Germany, but he has showed his evident class throughout the season, his goals coming in spurts.

A hat-trick against Hamburg and a double against Nuremburg three weeks later show that he has the ability to absolutely turn a game on its head and this could be vital for minnows South Korea.

If Heung-min is made the focal point of the side and manages to turn his erratic performances into something more consistent, then S. Korea may just find themselves in the knockout stages and beyond.

2. Mateo Kovačić

On his day Kovačić is a sublime player, able to glide past players and make difficult passes almost at will. He has been linked with a move to Premier League clubs such as Manchester United and Liverpool, but has recently pledged his future to current club Inter Milan despite some reports stating the youngster had fallen out with boss Walter Mazzarri.

Croatia have a squad bursting with talent and Kovačić's link-up play with the likes of Ivan Rakitić, Luke Modrić and Mario Mandžukić could be devastating. Croatia are certainly one of the dark horses of this summer's tournament. If their vast array of midfield and forward talent are firing on all-cylinders against Brazil in the opening game of the tournament, then the hosts may find themselves playing catch-up from the very beginning.

1. Bruno Martins Indi

The flamboyant defender has a huge personality and the talent to match. As a result, he may soon find himself following Dutch coach Louis van Gaal to Manchester United. The relationship between the two is well documented and could be instrumental in Martins Indi's World Cup and beyond.

The young defender will have a tough job on his hands, however, playing in a Dutch defence that looks very average on paper. The Oranje are as blessed as any in the attacking department, but without a defence to base it on they may find themselves in trouble against tougher opponents.

If he can find a way to marshal his fellow defenders and provide cover for the likes of Arjen Robben, Wesley Sneijder and Robin van Persie then the Netherlands could very well win this year's World Cup.

Kovačić, however, will have to improve his end product if he is to be remembered fondly after this tournament. His recent goals and assists tally have been poor for Inter despite flashes of technical brilliance.
