The Nigerian international has improved in his performances under Unai Emery this season, being particularly impressive in the victories over Fulham and Leicester.
Ozil was Arsenal's man of the match on Monday night, at the heart of every attack and grabbing a goal and an assist against the 'Foxes'.
Iwobi, 22, remarked on what he has learned from Ozil in training with the 'Gunners': "Mesut will come across as laid back but he is helping everyone in a different way. He helps me a lot. He gives me advice. He jokes around but always tell me I can do more - even last night he was saying I can do more.
"But he is always happy, always telling me and giving me the confidence to express myself.
"I have been training with him since I was 17 and I have seen what he can do. The quality he has is not just in training but as you can see in the match last night, he is a world-class player."
