Manchester City manager Roberto Mancini has said that Carlos Tevez is not 100% fit following the Argentine's successful return to the first team.
Tevez made his first City appearance since September during City's 2-1 victory over Chelsea at the Etihad tonight and provided Samir Nasri's winning goal.
His contribution pleased boss Mancini, who believes that his side were deserving winners.
"I'm happy because Carlos Tevez did well, also he's not in good form. I don't think he's 100% fit but he knows football," said Mancini.
"After their goal I felt squeaky bum time. But when they scored their goal, I don't think we deserved to go behind.
"I think we deserved to win the game because we had three or four chances in the first half and we missed them."
Mancini's side are now one point behind local rivals Manchester United in the Premier League title race.
