"He had a relaxing three days off at the weekend".
Ozil has looked slightly out of place when Emery has deployed him on the right wing rather his normal central role as a No. 10, but Emery reiterated that the German is happy switching between the two.

Things like that can happen in every game, and that's why football is so hard.
