On Thursday, reports emerged of a training ground incident between Bayern Munich stars Robert Lewandowski and Kingsley Coman.
According to Bild, the two teammates were involved in a punch up, with both players hitting each other in the face while trading verbal insults.
Several players including the likes of Niklas Sule and Jerome Boateng were needed to break the fight up before the pair eventually calmed down.
The orginial report suggested that Lewandowski sparked the brawl by making a comment that suggested Coman wasn't taking the practice session seriously.
But new details have since emerged to suggest that this has been a long time coming and that the bad blood between the pair is nothing new.

Bild have produced a follow-up story titled 'This is behind the brawl by Lewandowski and Coman'.
They suggest that the Polish striker has a fundamental problem with his teammate's style of play this season and was angry with Coman's performance in Bayern's defeat against Leverkusen.
"Robert Lewandowski has long been annoyed by the style of play of Coman, the reason: Too many dribbles, too few successful passes & crosses to the striker," the report began.
"Especially in the defeat against Leverkusen, Lewandowski was very angry at Coman as he barely passed him the ball."
Elite players like Lewandowski and Coman are obviously very competitive - they need to be in order to perform at the highest level.
But to start a physical altercation with a teammate because he doesn't pass the ball enough seems a bit excessive.
Thankfully though, according to Bayern manager Niko Kovac, the incident was a one-off and is now 'done and dusted'.
"There was a fight between two players who were named in the media," Kovac said at his Friday press conference, per the Mirror.
"The three of us discussed it after training, and both apologised for their behaviour and were sorry for what happened.
"No one is being fined because both players were understanding, and being understanding is very important now. The matter is done and dusted."News Now - Sport News
