19-year-old Bellerin is another youngster who was thrust into first-team action due to injuries this season. In this case, it was Mathieu Debuchy who made way for the pacey full-back, who is widely regarded to be one of the quickest players in the Premier League.
Wednesday night, Manchester United took on Newcastle at Tyneside, and bagged all the three points after a smash-and-grab victory in the final minute. Here are four key points from the game.
What looked like a minor disaster of a season three months ago could turn out to be an unqualified success by the end of May - and leave them set up for a genuine title push next season. Watch out.
The public reaction to the announcement that English Premier League clubs will receive £5.1bn for the domestic television rights from 2016-2019 flags the need for integrated thinking by the clubs when deciding where to invest this massive cash inflow.
In the past few years, the first thing that comes to mind when someone mentions the FA Cup is no longer a David vs Goliath match where the underdog emerges triumphant. It is instead the fact that many of the top teams field an almost different starting XI, resting their key players for the league.
As a long-standing Spurs sympathiser, it's faintly disappointing to see them slide their way back out of the top six, but it's hard to seriously argue that it's not deserved.
Luck in football is little more than a myth and blaming a supposed lack of it is a lazy and convenient excuse for failure, while being jealous of others is failing to see what they do better.
When the words long and ball are read or heard, many would conjure up images of Sam Allardyce and Tony Pulis embracing as the likes of Peter Crouch and Andy Carroll frolic around them. However, many fail to consider that this tactic can be hugely effective, if executed correctly.
Given the positive reaction both Chelsea and West Ham fans have had to their clubs' support of the living wage, it's hard to understand why this is such a battle. A survey for the GMB union found that 84% of football supporters want Premier League and Football League clubs to pay their staff a wage they can live on. It's the right thing to do, and the goodwill that paying the living wage would create would be huge. Making sure people are paid a decent wage is not just the right thing to do, it's good for working families, it's good for business and it's good for the economy.
Going to Pay to View does not deny people the opportunity to watch altogether, but the money that it brings, if well spent, can provide thousands with new opportunities to get involved: in this respect, it seems that pay to view broadcasting can be the egalitarian way, after all.
Every manager on the globe would've sacrificed their left arm to have a striking trio containing Wayne Rooney, Robin van Persie and Radamel Falcao at their disposal, right? For Louis van Gaal, the trio seem to give him more of a headache than anything else.
Compare former Manchester United midfielder Anderson with Cesc Fabregas in 2015 and people will rightfully question your sanity. But back when he first moved to England, however, it was actually a reasonable comparison...
Spurs haven't progressed over the last year. They're actually three points behind where they were at this stage last year, but their improved performances have kept fans relatively happy so far. There's a time when 'rebuilding' stops working as an excuse though and this - after Pochettino's second transfer window - is it.
At 45, there is still plenty of time to rebuild his reputation, but it needs to be done elsewhere. His reign now carries an air of inevitability and an inescapable sense that his continuation as manager will only bring further heartache to the fans and the club.
Essentially, Mourinho is playing the Football Manager game with real people. It's a foolproof plan and the easiest way of turning up money to improve the first team squad... Chelsea's transfer strategy is long term and it's such a strong blueprint that it's going to keep them at the pinnacle of English football for the years to come.
The moment when a player leaves a club isn't usually the time that his efforts get the fairest assessment. If he is going at the peak of his powers the fans are disinclined to appreciate the good times because they feel jilted. If he goes when his best days are behind him, fans are slow to remember him in his pomp.
