#10. Juan Mata
Juan Mata is undoubtedly a quality player. Mata is technically excellent with both feet, has great vision, and an ability to score goals which makes the Spaniard one of the best attacking midfielders in the world. However at Old Trafford, Mata’s career seems to have stalled. He’s being played out of position in a team that does not utilise his talents. This is a player who scored 20 goals from midfield in the 2012-13 season, a player who has won everything with Spain and everything except the Premier League at club level. Juan Mata can be the attacking focal point of nearly any club in the world and it seems he must leave Old Trafford to do that.
