Even if some of these players weren't aware of their flaws, all of them will go down in history as some of the most talented players to be banned from a football pitch for using an illegal substance.

The world is fully aware of Diego Maradona's cocaine addiction. But did you know Pep Guardiola was banned from the Serie A for using an illegal substance? Although the Spaniard cleared his name, he was handed a 4-month sentence.

Do you remember why Rio Ferdinand missed the 2004 UEFA Euro with England? Yes, a drug test was involved. Even if he didn't abuse any substances back then, his failure to remember to be given a drug test was enough to hand him one of the longest bans in football.

Wonder what players are included in the "Drug Cheats XI"? Have a look at the following video, courtesy from our pals at Football Daily.
