Mikel Arteta has said Mesut Ozil will have "very difficult" time receiving any playing time this season for Arsenal.

Ozil's contract expires in June.

"The team is evolving and you can see the level they are achieving," Arteta said.

"We want to evolve more and play better, so we need to maintain that. I try to select the players that are, in my opinion, in better condition.

"We are picking players we believe are the best for each game and as you can see, we keep changing.

"You can see ... that it is very difficult -- not just for Mesut but for some to make the squad. Every week, we try to pick the right players."
