Toure scored the opener as City claimed an impressive 2-0 win over Chelsea on Sunday, but the defending champions remain 12 points adrift of leaders Manchester United with 11 games remaining.
Sir Alex Ferguson's men remain hot favourites to regain the crown, but Toure still believes City can snatch it from their grasp and has urged his team-mates to end the season with a strong run.
"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."
Toure felt the result was one of the most important of City's season, even if he doubted it was their best display.
He said: "I don't think so but we needed to make a big performance because Chelsea is a big club, a big team with big players and we don't want to leave any more space (behind United).
"It is a very important result and you have to credit all the team, because they performed well.
"If you see the statistics of the game and if you see all the game, you see the defenders made a big, big game and Joe Hart makes a big, big save, and after that we have an option to win.
"I think it was the key moment of the game. If you look at the statistics, Lampard has never missed a penalty like that.
"Joe has made a fantastic save. It was a big performance from all the team and I am proud of that."
