#2 Carlos Tevez

Prior to entering the Tevez's arrival at the Theatre Of Dreams in 2007, the little Argentinian had a reputation for being a divisive character who was always after a move after a couple of years at a club, as he proved - somewhat justifiably - after being ignored for some of his time at West Ham under Alan Pardew.
However, what he did have was a pure love for the game, a hunger which was matched by his then strike partner Wayne Rooney, so in his case, it was very much a case of taking the rough with the smooth.
So it proved at United, where he scored several goals amid a series of arguments, which was never going to sit well with Sir Alex who always maintained that no player was bigger than the club as David Beckham, Ruud van Nistelrooy and even Cristiano Ronaldo can all appreciate.
He ultimately left the club in 2009 for neighbours Manchester City, which spawned the infamous 'Welcome to Manchester' poster. At City, he went on an extraordinary sabbatical after a row with boss Roberto Mancini and basically downed tools to get a move away from the club. Spells at Juventus and Chinese clubs followed as Tevez slipped sharply down the ladder.
