Fernando Torres has likened his struggles during his time at Chelsea as to 'swimming with wet clothes on'. The striker had a torrid time at Stamford Bridge following his £50million move from Liverpool, scoring just 20 Premier League goals over three-and-a-half years before being sent out on loan to AC Milan last summer. Torres failed to impress at the San Siro and, after the Italian club bought him outright, they loaned him to Atletico Madrid where he is yet to score in nine La Liga appearances, though he has scored three in four Copa del Rey matches.
