City head to Newcastle on Sunday for their penultimate game, leading Manchester United on goal difference.
Roberto Mancini: "Some say we will choke.
"That won't happen.
"It happened six weeks ago. I don't know why.
"Probably because we had some important players injured.
"But it won't happen now.
"We can lose because in football you can lose every game. But I am sure we will play a good game.
"We are the best team in Manchester. To be the best in the country we need to win the next two games.
"It is not important to beat United twice or beat Chelsea. The only important thing is to win the championship at the end."
"For playing against United the FA Cup game in January when we lost 3-2 was really important.
"It wasn't the 6-1. That game was easy.
"But in the FA Cup, we had to play with 10 men for 80 minutes and we were also 3-0 down.
"We recovered that game, and although we lost, they didn't have a shot in the second half, even though they had 11 players and we had a chance to score the third goal. It changed our mentality against them."
