Manchester City boss Mark Hughes was upset with comments from Manchester United rival Sir Alex Ferguson after their 4-3 defeat.
The return of Carlos Tevez was one of the main talking points and he hit a post. Hughes said: "He was fouled just before he shot so the referee got that wrong, too.
"I don't know why Sir Alex is saying it could have been six or seven. He doesn't need to say that. But this is just the start for us. We are not going away."
