7. Fernando Torres – Liverpool to Chelsea, £50m, 2011
Torres had probably showed at Liverpool that he was worth somewhere near that fee, but club must never have intended anybody to actually pay it as he form for the Reds had already begun to dip.
However, 42 goals in 154 games don’t make for good reading to Chelsea fans and his only saving grace is that he has helped the club collect an FA Cup, a Europa League title and a Champions League title whilst he’s been there and now the club are stuck in the unfortunate position of wanting to offload him but not taking a significant hit on the fee.
