Barton - who is currently on loan with Marseille - blasted Tevez last night.
Barton said: "Tevez? He's a mercenary"
"You can't really back him. Sure, I'm a hoodlum, I've got into scrapes - but Tevez is someone who in the last six months has gone on strike, gone off to Argentina to play golf, tried to get himself sacked.
"If that's not the epitome of what's wrong with modern players, I don't know what is. And don't forget, Tevez punched me first."
