City rarely had to leave second gear to beat their lacklustre Championship opponents 4-0, with Sergio Aguero's double complemented by goals from Yaya Toure and Carlos Tevez.
A walk in the park against a Leeds side who were out of their depth was just the tonic City needed after their Southampton horror show last week.
A 3-1 defeat left them 12 points behind Manchester United in their bid to retain their title and many consider it to be a foregone conclusion that the trophy will be back a Old Trafford come May.
But after watching Aguero score twice to take his tally of goals in a stop-start season to 13, the Italian predicted twists and turns if his men can start scoring on a regular basis again.
He said: "I hope Sergio will be like this from now until the end because if Sergio is like this, and our strikers continue to score a lot of goals from now until the end, I think the championship is not finished.
"This is possible but I think it should be confident, always. If we are 12 points behind - we lost seven points in three games. This can happen for every team. We play a lot of games.
"I think in this moment they deserve to be there because they played better than us. They scored more goals than us."
Part of City's problem this season has been a glut of injuries with various players, Aguero included, picking up niggles here and there. Gareth Barry missed out with an ankle problem and captain Vincent Kompany has a knee injury.
"For this we are unlucky this year. Gareth was nothing. I think he will be ready. We hope we can recover Vinny for the next game. Javi we will see [Monday] or Tuesday. I don't think that is a big problem, Mancini said.
