Bayern Munich star Sadio Mane punched his teammate Leroy Sane after Bayern Munich’s 3-0 defeat to Manchester City at the Etihad Stadium on Tuesday night, according to German outlet Bild via The Sun.

Mane was reportedly left fuming after an on-field argument with Sane.

The ex-Liverpool star “complained” about how his team-mate, once of Man City, spoke to him late on in the match.

The pair were pictured talking on the pitch in the 83rd minute following a mix-up over an attacking move.

And Bild claims that tempers flared in the dressing room once the game was over.

Words were said to have been exchanged. Mane then allegedly struck Sane on the lip, leaving a mark.

Team-mates were reportedly forced to separate the pair, with Sane being sent out of the dressing room.
