City will pick up their first title since 1968 if they beat relegation-battling QPR at the Etihad Stadium, although Manchester United still have a chance of stealing the trophy from right under the noses of Mancini’s men if they beat Sunderland and City slip up.
Zabaleta told the club’s official website: "We're only 90 minutes away from making history. If we succeed it is probably the start of a new era for this club.
"As a team, I think it's going to be without doubt the most important game we've ever played in.

"We want to do it for our fans who I know have been waiting for a long time. The only thing I can say is that all the players will do their best against QPR and we will do everything we can to win the title.
"We're very close but nothing is done yet, so we'll see on Sunday."
