Manchester City manager Pep Guardiola was delighted after his side's 2-1 away win at Manchester United.
With Chelsea in action on Sunday, the Citizens are currently alone at the top of the English Premier League.
And according to the Spaniard, victory at Old Trafford was deserved for his side.
"The first half was really good," Guardiola said.
"The last minute was a fantastic goal from Zlatan Ibrahimovic.
"In the second half, we knew they would change the system – they put Paul Pogba and Marouane Fellaini more in front and they were much stronger.
"The second half was an open game. We had many counter-attacks. When you have three on three, four on four, five on five, you have to take advantage because in the last minutes, anything can happen.
"We played good. We had the ball and when we lost it, we won it back quickly. We created enough chances.
"You cannot come to Old Trafford and dominate. It's impossible."
