Roberto Mancini: "I think it will be a difficult game. They play (to escape) relegation and will be strong.
"For us, it will be important. If we don't beat Aston Villa, it is like we didn't do anything against Chelsea.
"For this reason it is important to beat Aston Villa and afterwards continue to go. The season is not finished. It is impossible we can think it is finished now.
"There are 11 games to the finish. It is our job to play all the games 100 per cent and try to win always.
"Every game will be like this.
"When you are 12 points behind it is normal that if you lose or you don't win and Manchester United win the next game it will be difficult.
"We should try to win always. It doesn't change our way.
"I was not strong in mathematics in school, but with 11 games to play - 33 points - everything is possible.
"Last time we won the title from six games to go, eight points. I think everything is possible.
"I am very pleased. We played a really good game and it was important for us to beat Chelsea. I don't know if it was the best performance, we played other good games, but we played really well."
