Bayern Munich centre-back Jerome Boateng reportedly punched his teammate Leon Goretzka in the face during a heated training ground bust-up on Wednesday.
DailyMail UK, reports that Boateng became incensed after Goretzka mistimed a challenge during a small-sided game, which led to Boateng swinging out at his team-mate.
German publication BILD reported that Goretzka was originally angry after arguing with Thomas Muller over a penalty decision – with the former dismissively gesturing back to the veteran.
Boateng was quick to defend Muller and then just ten minutes later during a training game, Goretzka went in studs up on the German defender.
Boateng did not take the tackle well and reacted by hitting Goretzka square in the face with an open hand.
The report claims that Robert Lewandowski was quick to jump in and intervene while manager Hans Flick also calmed the pair down before talking to the Bayern centre back.
However just moments after the pictures emerged of the training ground bust-up, Goretzka was rapid to play it down by posting a picture of him smiling alongside Boateng while mimicking his team-mates punch.
Germany World Cup winner Boateng has been linked with a move away from the Bavarians in the summer, with Arsenal touted as a possible destination.
