Unai Emery said that Granit Xhaka was in the wrong for reacting to boos and jeering from Arsenal supporters as he was subbed off.

"He's wrong but we are going to speak inside about that situation. I want to be calm but, really, he was wrong in this action," said Emery.

Xhaka cupped his ear to the crowd, took off his jersey, and walked down the tunnel after getting subbed off in a 2-2 draw against Crystal Palace.
