Italian believes he has learned his lesson from the defeat to Liverpool, and insists that the club do not have any serious concerns about not finishing in the top four
The Italian has maintained throughout the season that the objective at Eastlands has been to finish in the top four and achieve Champions League football, and a victory over Tottenham on Tuesday would see them having achieved their target.
Currently sitting in fourth place, the former Inter boss believes that the six-point lead over Spurs - and four over Liverpool - should be enough to comfortably see his side through.
Mancini also says his side have learned from their 3-0 loss to Liverpool at Anfield last month.
"Yes, I have learned [from the Liverpool game]," Mancini said, according to The Telegraph.
"I think that for the Champions League we have no problem because we have three games to play and we only need three points, but if we want to close this situation we should try to win. It is impossible to rest players.
"It is like two finals in a week for us. This is the problem but now we should try to win against Tottenham. We will play with all the team as it’s important we play a good game and win as we know what can happen then.
"We know that it will be a difficult match because Tottenham are a fantastic team. They have played Champions League and when you do that the season is very difficult.
"That is what we are trying to achieve and if we beat Tottenham, it is finished."
