The Gunners picked up their first win with a 3-1 victory over West Ham last week.
The former Germany worldwide was sent home early on each of the the two days preceding the West Ham game on the advice of the club doctor.
"I like the possibility to have the player play different positions and then it depends each match for us and for the opposition", said Emery.
The Spaniard also explained his decision to ban sugary fruit juices from the club's training ground after he took over from Arsene Wenger this summer. We need to push, we need to have ambition, we need to have desire to improve every day.
'Mesut played with me on the right wing and also as No.10 and we are going to continue to do that.
"And when I was very young, my father was coming every day with one fresh orange fruit juice".
Stan Collymore has urged Arsenal to sell Mesut Ozil, brandishing the German as a "luxury" player Unai Emery doesn't need in his squad.
Emery didn't say whether Ozil will start, though, with the German's role in the team under some scrutiny after he was substituted midway through the second half against Chelsea two weeks ago.
Smith Rowe has not been involved in any of Arsenal's three Premier League games so far this term, but could see game time in the cup competitions and the Europa League. When he was playing in Madrid, I remember a lot of matches on the right.
The new coach told his loan department he wants the youngster available for him this season.
Warnock joked: "I'd love him to be here". You'll not hear me today'. "They prefer their orange juice fresh".
