City moved through to the FA Cup quarter-finals with a 4-0 win over Leeds United at home today and the Italian is of the belief that his side can bridge the 12-point league gap with neighbours Manchester United if they can continue to reproduce that type of scoring form, particularly star striker Sergio Aguero.
"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," Mancini said.
"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."
City resume their title pursuit with a home fixture against Chelsea this weekend whilst United are away to bottom-placed QPR.
