Arsenal boss Arsene Wenger says Shkodran Mustafi is out of the Christmas period.

The German has been hit by a hamstring injury.

Wenger said: "It's a bad one. He had nothing in midweek. I would not have played him today (if he had). I had Hector Bellerin on the bench. I could have played Holding or Gabriel. He wanted to play in Basel, because he said 'no it's nothing', and it was completely clear. I checked three times and there was no problem for. I don't know why it happened, but it looks a 'good' hamstring strain.

"Look, the minimum when you go out like that is 21 days. After that, today is December 10, so you are 21 days, that means he'll have a nice Christmas!"
