Wenger will tell him that he was fouled.If Xhaka has any sort of professional pride, he'd learn not to get caught like that. How long do we have to potty train? Certain basics you shouldn't have to be told what to do and if caught out you should know how to correct it as a player. As coach, Wenger should show Xhaka that the sloppy play is unacceptable and drop him. He shouldn't have to go through training drills with the guy and analyse endless footage of similar scenarios. He's a lost cause if we do.
