Ozil created the opener for Olivier Giroud as the Gunners ranout 3-1 winners.
Wenger said: "He [Ozil] was like the team - he had an outstanding first half and dropped physically in the second half.
"He was sick on Thursday night and I decided only today to play him, this morning. He had a stomach bug and didn't feel well.
"He dropped a bit physically in the second half, but his first half was outstanding."
