Arsenal boss Mikel Arteta has hinted Mesut Ozil didn't do enough in training to warrant a place in their Premier League squad.

Ozil has been left out of the 25-man list for the first-half of the season.

Asked if there was a reason for Ozil being frozen out, Arteta said, "No, I'm not very focused about what happened in the past. You will get to know me more but in the past eight years I didn't make them into a lot of accounts.

"You'll remember the atmosphere around him when I joined was pretty difficult. I asked our fans to support him and create a much better atmosphere and you remember and recall you could see the difference at the Emirates Stadium in two or three weeks. That was a way to support a player but look for the interests of the football club.

"But then I have to see daily basically the input, the performance and what every player brings to the team. From there I make the decision because I am the manager. I have to pick the right players to win football matches."
