#2 Kevin De Bruyne
Kevin De Bruyne joined Manchester City from Wolfsburg in 2015 for £55 million has since become one of the most important players for the club.
De Bruyne has arguably been the best player in the Premier League this season with his consistent remarkable performances against quality oppositions. He already has 9 assists in 18 games this season while also finding the back of the net himself 4 times. His passing, crossing and vision are exemplary reflected from his 84.5% pass rate success, 1.8 average crosses and 2.4 key passes per game while he doesn't shy away from taking a long range shot either. He is just 26 and his best years lie ahead of him.
His style of play will add a new dimension to the Barcelona midfield but it would be quite challenging to tempt him from a rival Champions League club when he is playing so well. But a fresh challenge and an opportunity to play with the best player in the world could persuade him.
