Fenerbahce midfielder Mesut Ozil mocked Arsenal boss Mikel Arteta after defeat at Manchester City.
The Gunners lost 5-0 on Saturday and are yet to earn a point or score a goal in the Premier League this season.
Ozil left Arsenal last season after falling out with Arteta.
With fans fuming on Twitter after the loss, Ozil used one of Arteta's favourite phrases to sum up the game.
The German simply tweeted: "Trust the process" in a nod to Arteta's unflappable belief that all will come good for the Gunners under him.
