Arsenal manager, Mikel Arteta, is struggling to hold a divided dressing room, with several of his senior players questioning some of his decisions.
According to The Athletic, some players in the squad are not happy with his man management of certain team mates.
David Luiz is understood to have been left frustrated, after he was left out from the team which beat Manchester United 1-0 at Old Trafford on November 1.
Luiz had suffered a muscle injury shortly after half-time in the defeat against Leicester a week prior, but declared himself fit for the United game.
Arteta disagreed and left the 33-year-old out of his squad, a decision which is said to have annoyed the former Chelsea defender.
Luiz has started just once in the Premier League since then.
Earlier this week reports claimed there had been a total breakdown in the relationship between Luiz and Arteta, but both parties have come out to strongly deny it.
