Fernando Torres: Liverpool > Chelsea – £50m
The Spaniard was already on the wane at Anfield when Chelsea decided to come in with an incredible amount of money for his signature.
Could never live up to his heights at Liverpool and Atletico Madrid with the West London club, his total of 46 goals in his three and a bit seasons costing them over £1m per strike.
Though Chelsea fans might say his goal against Barcelona to seal their Champions League semi-final win in 2011 might have been worth any fee that was paid for him, you’d have to say his time with the Blues was overall a failure.
