Roberto Mancini has told his Manchester City players to heed the lessons learned from Manchester United's win over Wolves.
United put on another late, late show to snatch a win at home to Wolves last weekend and Mancini wants his side to show a similar steely resolve in tomorrow night's sell-out showpiece.
"They know now we are a strong team, the situation has changed," the Manager declared at a packed pre-match press conference on Tuesday morning. "We have great respect for them, but we know we can be better than them now. It should be a good game.
"We played at the same level over the last few derbies, and we only lost in the last minute. That's important to remember, but we are a different team this season. There are two good squads for tomorrow night, so anything could happen.
"United play to the last second, they beat Wolves late because they have a strong mentality. They have won a lot of trophies, and that is what happens when you win over a long time. But we matched them last season and we have to remember that."
