The 29-year-old was restored to the starting line-up for the Gunners after he sat out Arsenal’s win over West Ham United last weekend at The Emirates due to illness.
There had been suggestions of a bust-up between Emery and Ozil in training, but the Gunners boss moved to deny those reports after last weekend’s victory.
Ozil featured for 84 minutes on Sunday as he helped the Gunners to make it back to back wins in the top flight under their new manager.
And new Arsenal manager Emery was delighted by the performance of the German playmaker in Wales.
Speaking at his post-match news conference, Emery said: “I think today in the second half Mesut played a good match because he worked every minute that he was on the pitch.
“Maybe with the control and possession [we had] in the second half, and the positions on the pitch, he feels better on the pitch.
“I want to give every player the same condition and every player is very important. With Ozil and his quality, I think we need… his quality for the team.”
Ozil will be hoping to feature for Arsenal when the Gunners return to Premier League action after the international break with a trip to Newcastle United.
Emery has been tasked with steering the north London side back into the top four after they finished sixth and without a trophy under Arsene Wenger last term.
