Ten worst Chelsea transfer gaffs, including £50m flop Fernando Torres & Daniel Sturridge sale to Liverpool

7) Tal Ben Haim

After becoming one of the most solid defenders in the Premier League during his time at Bolton Wanderers, Tal Ben Haim made the move to Chelsea in the summer of 2007, but coped badly with the step up to a bigger club and quickly fell out of favour. The Israeli international has played for seven clubs since then, including the likes of Portsmouth and Queens Park Rangers, never looking like getting back to his best.
