Mikel Arteta has turned Arsenal into Premier League champions – but he’s fallen out with a few players along the way.

Arteta had to make tough decisions to trim down Arsenal’s previously bloated and arguably overpaid squad, but that hasn’t always gone down well with the dressing room.

Issues of discipline were a common theme with players Arteta has brought the hammer down on, with some players having something to say about the Spaniard in return.

So here are some players he fell out with, and what happened next. Spoiler: most left.

Let’s start with the big one.

The longer Arteta stays at Arsenal, the less and less his reign will be defined by his decision to freeze out Mesut Ozil, but for at least the first year it was the defining aspect of his time in the dugout.

Adored by the fans, Ozil was for many years an undeniably world-class talent. But when his form dipped, so did Arsenal’s, and Arteta evidently felt he had to move the club forward.

“I tried my best, I tried to give him as many opportunities as I could… I’ve been patient, given him opportunities and been fair,” Arteta said on Ozil, who by the end of 2020 was completely out of Arteta’s Arsenal set up.

There were always questions over how the World Cup winner fit into Arteta’s tactical set-up, and over time tensions between the playmaker and his coach seemed to worsen.

“People have been trying for two years to destroy me, to make me unhappy, to push an agenda they hope will turn the supporters against me and paint a picture that is not true,” Ozil said during the pandemic, when he reportedly refused to take a pay-cut.

“Possibly the decision affected my chances on the pitch, I don’t know.”

Eventually, Ozil was allowed to leave for Fenerbahce in January 2021 on a free transfer. But he didn’t stop making his feelings towards Arsenal and Arteta known.

After the Gunners lost 5-0 to Manchester City earlier in the season, Ozil sarkily tweeted the following:

Martinelli was an Arteta stalwart until he wasn’t; the decision to freeze him out in 2026 and sell him to Al-Hilal seemed brutal.

Perhaps it was understandable from a footballing viewpoint – Martinelli hadn’t kicked on as hoped and injuries had dulled his impact at the Emirates.

But treating a long-standing squad member with such coldness reportedly didn’t go down too well in the dressing room.

Arteta was a conspicuous absence from Martinelli’s farewell posts on social media.

Pepe didn’t have the easiest time in North London. And that’s putting it lightly.

After inconsistent performances, a red card for a headbutt against Leeds in 2021 caused the Arsenal manager to go red himself.

“It’s very clear, it’s unacceptable. It’s unacceptable,” was the extent of what the Arsenal manager could muster post-match.

From then on, Pepe featured less and less in the starting squad, often deployed from the bench. He was released to little fanfare in 2023.

Guendouzi went from a regular starter to a mere fringe squad player in a very short period of time following Arteta’s appointment in December 2019.

After the Frenchman grabbed Neil Maupay by the throat during a match, Arteta had had enough and ordered the player to train separately from the rest of the squad.

When asked why Guendouzi was featuring less, Arteta was clear.

“The reason is that players who, in my opinion, are training better, behaving better and are more applied to deliver on the pitch, what we want, are the players selected,” he said after excluding Guendouzi against Newcastle in February 2020.

Guendouzi was loaned to Hertha Berlin for the 2020-21 season and cut adrift permanently soon afterwards.

This one was much less of a falling out and more of an amicable, footballing disagreement.

Maitland-Niles was getting few minutes under Arteta and even less in the midfield – his preferred position.

The young Englishman had grown frustrated and asked Arteta to let him leave on loan, even going on social media to ask to leave.

“Ainsley came to me and explained the reasons why he thought that the best thing for him in his career right now is to move away,” Arteta said.

“We already had this conversation in the summer and we decided to keep him at the club and assess the situation in December, but with the amount of minutes that he has played, he’s entitled to that opportunity.”

So, when Roma came calling, Arteta begrudgingly had to let Maitland-Niles go.

Have Arsenal ever come out on top in a transfer deal involving Chelsea?

Ashley Cole left for bigger and better things, Giroud went and won two European honours with the Blues (one over Arsenal) while the Gunners have had a past-it Douglas Luiz and… Willian.

But things didn’t work out for Willian at Arsenal. Arteta, who had done everything he could to bring the Brazilian to the Emirates, quickly stopped seeing the Brazilian in his first-team plans.

“He terminated his contract and he did it willingly,” Willian’s agent has since said.

“I spoke to Arsenal. I had a meeting with Arteta and [technical director] Edu, they explained this [Willian at Arsenal] has not gone well.

“I think Willian did the right thing, he went for the project and the project wasn’t there.

“Unfortunately, I’d have to say, which player has moved to Arsenal that has not been a disaster in the last couple of years?”

Another big name to fall afoul of Arteta, Aubameyang left Arsenal for Barcelona in 2022 under something of a cloud.

It was a sad end to what had been a largely brilliant few years in North London for the Gabonese international, with Arteta’s decision to strip Aubameyang of the captaincy and remove him from the squad the key reason the forward left.

“The decision that we have taken as a club is very clear,” Arteta said when asked why Aubameyang was excluded from the team.

“It is because we believe that he has failed to be committed at the level that we all expect and agreed. It is as simple as that.

“You can listen to individuals and you can understand different cultures, but that commitment and passion has to be there. Unfortunately, it wasn’t.”
