William Gallas has admitted that he used to 's*** himself' when he came up against his former Chelsea team-mate Didier Drogba.
The pair enjoyed two hugely successful years together at Stamford Bridge, winning back-to-back Premier League titles between 2004 and 2006.
But it wasn't until he left to join Arsenal that Gallas, who is close friends with Drogba, was able to fully appreciate just how good the striker was.
The Ivorian netted 32 goals in his first two years with the Blues before hitting top form in the season after Gallas had departed for the Emirates.
