The headline is fairly self-explanatory, and any fan of English football will be aware that Chelsea has had the biggest turnover of player transfers over the past 10 years or so.
Some have came, saw and conquered, while others have come to see their careers fade and die. It's a part of football, but the latter seems to happen far too often at Stamford Bridge for it to be purely just a coincidence.
Fernando Torres still has time to prove he is not a flop and has made a decent start to the season, with two goals to his name so far. But the £50 million striker knows the pressure is on to deliver, although he is exempt from this list.
