#2 Kevin de Bruyne (Manchester City)

De Bruyne is a part of what is arguably one of the greatest transfer misjudgements in modern football. In January 2014, Chelsea, managed then by Jose Mourinho, sold de Bruyne to Wolfsburg for just £17 million. Fast forward four years, and the Belgian is one of the best midfielders in the world, and worth infinitely more than that £17 million. How Chelsea would love a player like that right now.
Chelsea’s loss has been Manchester City’s gain, as since signing for City in 2015, he has been arguably the best player in the Premier League. He stepped up to a new level last season, in the process becoming the first player to win the Premier League Playmaker of the Season award for his 16 assists. He is deadly in and around the opposition box, either with his ability to find a team mate, or find the back of the net. He is probably the best playmaker in the world, and at 27, he still has a lot of time left at the top of the game.
