Manchester City manager Manuel Pellegrini hailed his side’s performance after they comprehensively saw off rivals Manchester United with a 4-1 victory.
Sergio Aguero struck twice, while Yaya Toure and Samir Nasri also got on the scoresheet as City produced a ruthless display.
“It was a very important result, normally you don’t expect to win 4-1 against Manchester United but the most important thing was the way we played -- I am very happy,” Pellegrini told the club’s official website.
“Normally derbies are more equal but today we had a very good day and that allowed us to have superiority against Manchester United this afternoon. Winning the way we won today will give us a lot of confidence.
“I would be very happy if we win all of the games 4-1 but we must improve every game. Not every game is the same, we are just starting in another way to play and I hope we will improve every day.
“Always winning against Manchester United and the way we won could have an important impact.”
City were 4-0 up by the 50th minute but failed to add to their tally as Wayne Rooney struck a consolation goal for United late on.
Pellegrini, though, was not concerned by his side’s inability to go on and win the game by a bigger advantage.
“I’m not disappointed,” he said. “I think we played a little bit quickly in the second half, I think we tried to play box-to-box which wasn’t the way to play in those circumstances. We had so much space and we are always trying to tell players to play independently of the score but I think that would have been useful for us in the last forty minutes.
“We have to play United again in three months but until then, the fans will enjoy that result. For the team, winning the way we did today will give us a lot of confidence."
