Samir Nasri was quick to hail Carlos Tevez after the Argentine set him up to score the winner in their 2-1 success over Chelsea.
Tevez came off the bench and his cute pass on the edge of the area played in Nasri as City came from a goal down to claim a crucial three points in the title race.
Nasri was delighted for Tevez on his return to action.
"I am really happy for him (Tevez)," Nasri said on Sky Sports HD1.
"He has showed great spirit and today showed he can be really important until the end of the season.
"It's good that it was him who gave him the assist."
City defender Micah Richards, who captained the side, admitted the victory was a huge result in their battle with city rivals United for the title.
He said: "It's a massive result for us. After we went 1-0 down heads could have dropped, but we kept on going and managed to get three points.
"We did have to win tonight, we gave everything and showed good character.
"The lads will be delighted with that."
