2) Joey Barton
Make of him what you will, but another man constantly attracting headlines for the wrong reasons is Joey Barton.
His career and life have been marked by numerous controversial incidents and disciplinary problems. He has been convicted twice on charges of violence.
In 2008, having already served time in prison, he was given a four month suspended sentence after admitting to assaulting former teammate Ousmane Dabo during a training ground dispute the previous year.
Barton has been charged with violent conduct three times by the FA: for the assault on Dabo, for punching Morten Gamst Pedersen in the stomach and for attacking three players on the final day of the 2011–12 season.
