5. Carlos Tevez
Tevez technically wasn’t a Man United player, having joined on a two-year loan deal from West Ham. He was often a figure of frustration during his time at the club, bagging a handy 14 one season and a less than impressive five in the other. He did form an exciting trio with Wayne Rooney and Cristiano Ronaldo, but he was always the quieter of the three. United tried to keep him, but he opted to join Manchester City instead where he went on to play a central role in their first Premier League title win and is now busy keeping Juventus at the summit of Serie A.
