Ozil was missing for Arsenal, with illness supposedly the reason why - the seventh time since January 2017 he has been missing from a match day squad for that reason.

"No problem with the player".
Emery added that Ozil left the training ground on Friday because "he was going to his home, because he was sick".
Danny Welbeck came off the bench to wrap up the points in stoppage-time.
"I am not happy with the result but I am very happy with the performance of the team", Pellegrini said at a news conference.
It's an enticing London derby we have for you with the small sub-plot of Wilshere making his first return to Arsenal since leaving to join West Ham in this transfer window.
Issa Diop had the misfortune of putting his own side behind as he put into his own goal with 20 minutes left to play.
"We got our first win today which was massive for us, but there's a long road ahead and a lot of games to play".
Despite the three points, Emery said there was still plenty of room for improvement and that his team couldn't find the right balance between attack and defence in the first half. "Arsenal didn't create too many chances during the game, we created double the chances as them".
