The Nigeria international spent 15 years with the Gunners, coming up through their junior ranks before making 149 senior appearances for them.
Iwobi made a £28million deadline day switch to Goodison Park in August 2019.
He told Sky Sports: “It’s tough going from that at Arsenal. One manager, obviously Unai Emery came, and yeah it was a bit different because there was a lot of different methods, things were getting changed, positions, formations, and I have had to play in numerous positions, so maybe I was a bit unsettled, but I don’t really want to say like an argument or problem because at the end of the day, as footballers, we should be able to cope with the situation.
“Maybe I should have handled it better, but whether what happened in the past has made me who I am today, so there’s no regrets.”
