Two players exchanged blows in the Bayern Munich dressing room following Tuesday's defeat, according to German tabloid Bild.

Tuesday was a painful day for Bayern Munich in the UEFA Champions League. Not only did the German giants suffer a gut-wrenching defeat away to Manchester City in the first leg of their quarterfinal showdown, but two players later got into a physical altercation after the final whistle.

They were none other than Sadio Mane and Leroy Sane, with the Senegalese ace reportedly punching his teammate in the dressing room after the game in an altercation that initially sparked from an exchange of words on the pitch.

According to Bild, this all stems from an argument on the pitch late on in the defeat. In the 83rd minute, the former Liverpool winger ran into space for a through ball when the German attacker wanted his teammate to come short to receive the pace and link up.

This argument continued until the full-time whistle before Sadio confronted Leroy in the dressing room as the Senegalese ace wasn't pleased with how his comrade talked to him. Things quickly escalated, with Mane later punching Sane in the face and leaving him with a cut lip.

The other players quickly intervened to separate the two and that alone ended the physical altercation. Sane had to be taken out of the dressing room to calm things down and he had to be picked up privately in Munich after the team flew back from Manchester. Sadio, on the other hand, traveled with the team bus.

Bayern Munich are yet to issue a comment regarding this controversy but it is just another issue for the Bundesliga giants to deal with. Additionally, this is not the first time Mane has been involved in a rumored incident as the summer signing allegedly fell out with former head coach Julian Nagelsmann after being dropped from the lineup.

The Bavarians, who were recently eliminated from the DFB Pokal, are all but out of the UEFA Champions League as only a miraculous comeback at the Allianz Arena can secure progression to the semifinal.

As a result, Tuchel could have done without a fractured dressing room. It will be interesting to see how Bayern Munich handle this situation as the club look to successfully defend their German top-flight crown.
