Manchester City captain Vincent Kompany believes his side's impressive 4-1 win against arch-rivals United will not have a significant bearing on the title race.
Kompany and his Manchester City teammates were in imperious form on Sunday as Manuel Pellegrini's side comfortably defeated last season's Premier League champions.
The Citizens raced into a 4-0 lead courtesy of goals from Yaya Toure, Samir Nasri and a brace from Sergio Aguero before Wayne Rooney reduced Manchester United's deficit in the 87th minute.
The Belgium international believes his side wanted the three points more than David Moyes' side.
Speaking to Sky Sports, Kompany said in the aftermath of City's victory: "Maybe the game meant a bit more to us than to them.
"We've been looking forward to this fixture, and our fans have been speaking about it for a long time - and we need to win those kind of games.
"We've got an unbelievable home record and there's no reason why we should fear the opposition, even though they are very good.
"We did play with two very good strikers. Defensively, we've had a very good record for the past three years, so we knew that we could attack and we could defend. Mainly I think we stayed so calm.
"I think you make a statement over the whole season. It's too early to say if it's a defining game.
"But it would be silly to give away those very precious three points. We need to win the next games, and then we'll enjoy what we've done today.
"It's only three points, but it gives us all the confidence and allows the fans to celebrate for a few days.
"As I said, when we won 6-1 at Old Trafford, I said we need to stay humble. It's only three points, but it gives us all the confidence and allows the fans to celebrate for a few days."
The win saw Manchester City move within just two points of current Premier League leaders Arsenal.
City manager Pellegrini will be hoping his side can follow up their derby day win when they take on Wigan Athletic in the Capital One Cup on Tuesday.
