Doubts have been raised over City's ability to handle the physical stuff, but Eriksson says: "No I am not concerned about any over physical approach from them.
"Last week against Arsenal it took us 19 minutes to give away a foul. That is a long time in a game of football and I don't want to see that again.
"I don't want us to be a stupid team and kick like others do, but you can't let the opponents dominate you. Sometimes you have to push them, tackle them or whatever, but it can't take 19 minutes before you are close to them.
"As for United, again I am not worried about an over aggressive style when they are up against it, they know what happened in August and that is enough for them."
