Ahead of the first leg of their Europa League clash with Zenit at Celtic Park, the Englishman recalled his time under the Italian and said: "When I went to City I only played a few games under him. I am much different.
"But there are so many players there that didn't really get as much game time as they would have liked.
"I am a much more different now, than then.
"I don't have a point to prove to him, it's for myself.
"You have these targets and the levels that you want to play at and for me it is working hard and giving it 100 per cent.
"He is a very tactical manager, I am sure he will be doing a lot of tactical work to stop us performing tomorrow and I am sure he will be wanting to win the game."
