The Swede was pleased to hold City 0-0.
"We had a game plan and it worked - to sit back with the back four and midfield, similar to Chelsea you could say. And then when we got the ball, to try to get some corners or free-kicks and try to score those set pieces.
"You could see they were getting frustrated and a bit annoyed at each other as well. That was good for us when we see that, and it makes us work even harder. We really frustrated them."
