The Togo ace said: "I don't think I have anything that I need to show Arsenal.
"We all know how good they are - but now I play for City so I'll do everything to help this team now.
"It'll be a good game and will be funny as well playing against players who I see like brothers - such as Song, Clichy and Eboue.
"Playing against them will be strange - but it is going to be good.
"I'm looking forward to it because I'm going to be up against old team-mates, ones who made me into a better player."
