Manchester United captain, Bruno Fernandes was involved in a dressing room fight that involved three other players, The UK Sun reports.
The squabble followed the Red Devils’ 3-1 defeat to Brighton in the Premier League last weekend.
Fernandes is said to have confronted Scott McTominay after the match at Old Trafford.
The center-back pairing of Lisandro Martinez and Victor Lindelof also engaged in a heated exchange in the dressing room.
It took manager Erik ten Hag’s intervention to restore order in his squad.
United have now lost three out of their first five Premier League matches and sit in 13th place on the table.
They are away to Bayern Munich on Wednesday in their first Champions League clash of the season.
