Erling Haaland found his scoring boots on Sunday.
The Norwegian's brace helped Manchester City to a 3-0 win against United on Sunday.
His boss was happy.
"Erling has been incredible since the start but this season he is better than ever. I would say better than the Treble year," said Pep Guardiola after the game.
"He is dynamic and I don't judge him for the clearances, we want him to score goals and to help us."
"Erling has never disappointed since he has arrived. He has shown the commitment and signed a contract for many years. He is a special player."
