A well-known bon vivant, Mutu came crashing down to earth in 2004 when he failed a random drug test, costing him his £60,000-a-week job with Chelsea. In an ultimate playerboy declaration, Mutu later claimed, "The only reason I took what I took was because I wanted to improve my sexual performance. It may be funny, but it is true. I did not take cocaine. I took something to make me feel good."
