FIFA vice-president Jim Boyce believes Manchester City forward Carlos Tevez should be banned "from taking an active part in football" if he refused to come on as a substitute during the side's Champions League defeat to Bayern Munich on Tuesday night.
City boss Roberto Mancini said he felt Tevez could never play for the club again after claiming the player refused to go on in the second half, and the club have since suspended the Argentina striker for two weeks.
Northern Irishman Boyce, speaking in a personal capacity, told Sky Sports: "I believe FIFA should have the power to ban the player from taking an active part in football. If he has done what has been said, then I think his club would be better off without him."
He added: "If Manchester City prove it, write to FIFA and state the exact circumstances that happened, I would have no problem with that whatsoever. It hasn't occurred before but I think what happened was despicable."
"If this player did what he has been accused of doing, then if Manchester City were to release him I don't think it would be right if he could go and earn a considerable amount of money somewhere else next week.
"I would have no problems if some sanctions were imposed by FIFA in that respect.
"People within the clubs and within the top level of FIFA have to consider that if Carlos Tevez does it, who's to stop someone else doing it the next week or the week after?"
