1. Fernando Torres
Chelsea fans must have thought Fernando Torres had the guile, finishing ability and big-game temperament to be Didier Drogba's long-term successor at Stamford Bridge when he signed for £50m in 2011, but is a pale comparison to the star who lit up Anfield prior to that stunning switch.
Torres has only managed a frankly woeful 19 goals in 105 Premier League appearances for the Blues though, which despite the trophies coming thick and fast during his time in West London is a very disappointing contribution.
Blues boss Jose Mourinho looks to have run out of patience with a player who continues to work tirelessly in search of former glories, but surely needs either a fresh challenge or a step down in level to recapture even a glimmer of his true worth before a glittering career draws to a close.
