Former Manchester United midfielder Anderson has been suspended by current club Internacional after he punched a team-mate in training.
The Brazilian was not particularly renowned for hitting the target during his eight-year spell with the Red Devils, but he makes no mistake here after promising youngster William appeared to poke fun in a session which quickly turned ugly.
Anderson landed a right jab on his team-mate after he blazed a shot over the bar and the pair had to be torn apart from each other by other players and staff.
Blood was visible from William’s mouth while Anderson, who last played a full game in June, left the field on his own after being berated by assistant coach Odair Hellman.
Both players are facing a lengthy lay-off after being suspended by the club who are struggling to retain their top-flight league status.
