Mark Hughes signed Adebayor for City from Arsenal in July 2009.
But things turned sour for the striker when Sparky was sacked five months later and replaced by Mancini, who soon made it clear the frontman was not part of his plans. Adebayor insists he has nothing to prove to Mancini - or City.
"I don't have anything to prove to City, they are a sacred club. I have a huge respect for the players because some there I call family - Yaya and Kolo Toure, Vincent Kompany, they are very good friends.
"But do I have any pressure that says I have to beat Man City because of the way they treated me, because they bought me expensively and sold me for cheap? No."
