2. Pep Guardiola

Pep Guardiola who is now one of Europe’s best managers from his time at Barcelona, Bayern Munich and now Manchester City, had received a four-month ban for testing positive for anabolic steroids in 2001 when he was playing for Roma.

Guardiola was adamant in his defense against any wrong doing and fought the case for six years. In 2007, he was officially cleared of the drug charges. However, the case was reopened in 2008 before Pep was once again cleared in 2009.
