Arteta added: “I’ve worked with players like this, I’ve had team-mates like this and there is always a moment where there is a click.

“I can accept a mistake, no problem, what I’m not going to accept is someone who makes a mistake and after he stops playing, he doesn’t want the ball, he doesn’t want to make decisions. That player is not acceptable for our team.

“But Musti after that he tried to play every single time, he went for every single challenge, he put his body on the line.

“He was down afterwards, yes, but he reacted and if he does that, he will overcome the situation. I ask him to play the way we want to play, he made a mistake, on another day it will be someone else.

“Obviously we want to minimise that as quickly as possible and find the reason why that happens, but I like his reaction after that.
