The manager says his team are capable of causing a first day upset.
He said: "All the teams have weaknesses and Manchester City also have them. More important than knowing the weakness is to play in a way to make them have trouble in that.
"If you don't have the ball, or lose the ball in two or three touches of course they will have possession and make it very difficult to exploit those weaknesses.
"That's why I hope we are going to play a good game, knowing that we will play against them but not changing what we do or what we think just because we are playing against them.
"After that we will see - we just played them in pre-season and we had a lot of opportunities that we didn't score. Every game is different and we will see what happens."
