5) Andriy Shevchenko
Long regarded as perhaps the best striker in the world with the likes of Dyamo Kiev and particularly AC Milan, Andriy Shevchenko was a big disappointment when he joined Chelsea, scoring only nine Premier League goals in two seasons.
6) Radamel Falcao
Another who is well on his way to becoming a total Premier League flop, Radamel Falcao was poor at Manchester United last season and looks no better for Chelsea this year, despite tearing defences apart during his time with Porto, Atletico Madrid and AS Monaco.
