Manchester City manager Roberto Mancini expects Carlos Tevez to go from strength to strength as his side chases the Premier League title.
Tevez inspired a 2-1 win over Chelsea on his return from exile as a second-half substitute at Eastlands on Wednesday.
The Argentine forward set up a winning goal for Samir Nasri as his side closed the gap on leader Manchester United to one point.
A Sergio Aguero penalty soon after Tevez's introduction had canceled out Gary Cahill's opening goal for Chelsea as City also claimed a 20th consecutive home league win, a record in the Premier League era and only the fourth time in history a top-flight club has reached such a landmark.
Tevez's appearance from the bench had been greeted by boos from sections of City supporters, still angered by the forward's self-imposed six-month exile from the club following his refusal to warm up during a Champions League tie in September.
But Mancini has no doubt the player will not take long to win over the dissenting few.
"I think it was important that Carlos made an incredible assist for Samir and all the supporters were happy with that," Mancini said. "I think Carlos needs more time, it's not easy for him but it's important that he is here now.
"Maybe in 10 days, two weeks, he can find good form. I think that will be important for us. Carlos is maybe not 100 percent but he knows football and he was important because he was incredible for us.
"I have spoken with Carlos every day this month and he knows he had to come off the bench and play 20 minutes in this game but he can play more in the future.
"He's an important player, he needs another two or three weeks to have good form but when he plays, he knows where to take the ball."
Mancini also insisted any ill-feeling between he and Tevez has been well and truly eradicated.
"That was finished a month ago when Carlos came back here," said Mancini.
"Now it's important for Carlo to play some games for us, for him, for his future."
The feel-good factor extended beyond the manager's dug-out with Tevez's teammates clearly content to have him back in the fold.
"I'm really happy for him," added Nasri of Tevez. "He's showed great spirit since he's been back and showed in this match he can be really important until the end of the season. It's good that it's him that gave me this assist.
"At 1-0 we showed great spirit and that is really important as we want to win the title and we know we have to win every game."
City, who faces United at Eastlands in April, remains firmly in the title race thanks to Tevez and Mancini is confident his team can still wrestles the trophy from Old Trafford.
"At times this season we have played fantastic football," he said. "I don't think we have played well the last three or four weeks, we have been so-so, but after tonight something can change. There are nine games until the end and we want to stay there."
For Chelsea manager Roberto Di Matteo, the decision to start with Fernando Torres in attack, leaving Didier Drogba on the bench, seemed to back-fire and the Spanish striker appeared unhappy, exchanging words with his manager, when he was brought off.
"I just thought to start the game, the dynamic of the team, it was going to be the right decision, he had a very good performance on Sunday," said Di Matteo of his choice of starting striker. "There is no problem with Didier. And no player is happy about being substituted but there is absolutely no problem with Fernando. I communicate with all my players, there is no problem."
Meanwhile, Di Matteo refused to be too downhearted by the first defeat of his reign as interim boss.
"Two weeks ago we were seven points behind third place, now we're six so we are going in the right direction," he said.
"We showed we can match the best teams in this league, we're very disappointed we didn't get at least a point."
