Tevez is pleased to have silenced taunting United fans after breaking their trophy drought on Saturday.
Tevez, who handed in a transfer request in December, said: "Winning the title is a great motivation for me to stay, it would make me so happy.
"It is what we all want and need - although now it's time to celebrate winning the Cup.
"Here we are trying to build a team to win trophies including the Premier League and we are focusing on that.
"But we remember very well that flag at Old Trafford which taunts City.
"Now it makes me very happy that they will have to take it down."
