Arsenal boss Mikel Arteta has been confronted by one player for playing favourites.
The Mirror reports the player, who hasn't been named, voiced his frustration that some individuals are being treated differently at Arsenal.
The confrontation took place during a tense team meeting.
Arteta is struggling to keep his head above water at Arsenal at the moment, with problems on and off the Emirates pitch.
The Gunners have won back to back matches in the Premier League against Chelsea and Brighton, which has relieved some of the stress.
But Arsenal have still had an extremely disappointing 2020 and are floundering down in 13th - nine points adrift of the top four places.
