Bayern Munich forward Sadio Mane punched team-mate Leroy Sane in the face after Tuesday’s Champions League defeat at Manchester City.
It was reported that Sane’s lip was bleeding after the altercation and the two players needed to be separated by their fellow team-mates in the dressing room.
The duo were seen on the pitch arguing in the latter stages of the match on Tuesday night, where City beat the German champions 3-0 at Etihad Stadium in the first leg of their Champions League quarter-final first leg.
Bayern Munich have not commented on the incident.
