Mikel Arteta "thinks he knows it all" and there are concerns about how "arrogant" he can seem at Arsenal, according to reports.
A source told The Independent that the Gunners boss isn't the most popular figure at the Emirates at the moment, with Arteta said to rule with almost complete authority like a "mini Arsene Wenger" but without the credentials.
Arteta's Arsenal have made a very poor start to the season, losing against both Brentford and Chelsea in their opening fixtures.
They currently sit 19th in the Premier League and are without the distractions of European football this season, and Gunners supporters are already growing tired by the way the club is being run.
This same frustration is allegedly shared by some inside the Arsenal dressing room, who believe the Spaniard's training sessions are "too clean" and don't prepare the squad for matchday.
Arteta currently has the backing of the Arsenal board and there are no plans to sack him anytime soon.
But the Spaniard will not be gifted the same patience as he was last season, and reportedly has until October to prove he is turning things around or face being sacked.
Arteta was booed by a section of the Arsenal fans following the 2-0 defeat by Chelsea, in which Thomas Tuchel's Champions League winners ran riot at the Emirates.
But the Gunners boss played down the pressure on him, telling the press: "I must thank the fans, even when things were looking difficult they tried to give the players a boost.
"I see a lot of positives with the crowd and the team today."
On the match itself, he added: "They were the better team. When they play at their best, which I think they did today, they are champions of Europe, have world-class players, and to match at that level is difficult.

"You can always do things better. In the first half, we had some difficulties. It took us a long time to regain the ball in wide areas. When we did it and we looked a threat, we didn't finish enough actions with the quality we need to.
"We concede two goals but the way the team responded and the crowd really helped because they never gave up, it gave us hope in the second half."
