The hosts routed Norwich 7-0.
"We knew before the game that we had to win this match after losing at Chelsea last weekend but I think we played really well right from the kick-off and fully deserved our victory," said the Argentina star to City's website.
"It was a good team performance and our midfielders and strikers did especially well. Everyone knows we have to perform to our optimum levels if we want to play regularly because we have two very good players for every position in the team but we all support each other no matter who plays."
