Yaya Toure still has belief Manchester City can retain their Premier League title.
"We are very pleased with the win because that is the most important thing for me," said the midfielder.
"We have to keep on going and try and win all our games because we know United are in the top spot.
"We needed 12 wins and we have to keep on going because we don't know the future and you can't say it is finished.
"For the football club and the fans, you can't give up now.
"We have 11 games remaining and in sport you never know what can happen in the future.
"We know we have a big calendar, more difficult than them, but we have to keep on going and try and win matches and not let any points (slip) away."
