Four Manchester United players were reportedly involved in a furious bust-up following Saturday's 3-1 loss to Brighton at Old Trafford.
Erik Ten Hag's side were beaten for the third time in five games this season, with goals from Danny Welbeck, Pascal Gross and Joao Pedro were enough to condemn United to their worst-ever Premier League start.
United were truly played off the park on their own patch and according to The Sun, tempers flared in the dressing room after the game.
A new report published on Monday evening claims there were two separate bust-ups. Captain Bruno Fernandes is said to have laid into midfield colleague Scott McTominay after his first start of the new season, while centre-back Lisandro Martinez and Victor Lindelof also got into it.
United, currently in 13th place in the Premier League, return to action on Wednesday with a Champions League group stage clash with Bayern Munich.
On Saturday there were boos when new £72 million signing Rasmus Hojlund was substituted on his full debut, while jeers could also be heard at the final whistle as a dismal period for United continues.
The club's business in the transfer market was deemed a tad underwhelming after there was no movement in regards to a takeover and the handling of the Mason Greenwood situation was less than impressive to say the least.
Brazilian winger Antony is on an extended leave of absence amid allegations of domestic abuse and assault, while Jadon Sancho has been banished from the United first-team after refusing to apologise for Ten Hag.
The England international had hit back at his manager for claiming he was omitted from the squad for the 3-1 defeat to Arsenal for not performing at the expected level in training.
Sancho, who said he had been "a scapegoat", is "on a personal training programme" until the matter is resolved.
There is also the small matter of Harry Maguire still being on the books of United despite links to West Ham following the decision to take the captaincy from him.
