Aguero shone with goals in each half as City thrashed their neighbours in the Barclays Premier League on Sunday.
The Argentina striker said: "The most important thing is that the goals gave us the win.
"I'm very happy that we won three important points, especially against United.
"All the team were brilliant, the defence as well. We're all one team. There are no individual heroes.
"We're all heroes, even the players on the bench. The most important thing is we won and we are happy."
