Arsenal boss Mikel Arteta wants to see more from Saed Kolasinac defensively.

The full back has always been known for his attacking runs, especially if he gets to play a wing back role.

But when Arsenal play a back four, Arteta wants to ensure that Kolasinac is doing what is necessary on the other end as well.

Arteta made his comments after Arsenal's battling 3-2 win against Everton on Sunday.

Kolasinac suffered a shoulder injury in the game, which could rule him out for the coming games.

Arteta told the club website: "Well, I'm never happy when something happens like that [Kolasinac injury].

"With Kola he's been very unlucky with injuries, Bukayo [Saka] had some issues as well before the game but then he started to play after a few minutes.

"It was a great contribution offensively but as well there are other moments when he showed today that there is still a lot of margin for him for improvement, and he needs to keep his feet on the ground and we have to help him to do that."
