The Spanish coach is under severe pressure after his team lost another game, this time 1-0 at home to Burnley on Sunday.
And part of the issue centres around his response to a red card his winger Nicholas Pepe received against Leeds United two weeks ago.
Arteta stated in his post-game interviews after that match that Pepe had let down the team and behaved unacceptably.
According to football.london, some players were upset at seeing Pepe get such public criticism.
The source also claims Arteta's relationship with David Luiz is not good, while the fact he has left Mesut Ozil and Sokratis out of their 25 man Premier League and Europa League squads does not sit well with some players either.
