The reigning champions sit 12 points behind neighbours Manchester United with 11 matches remaining and Toure feels that if City go on a winning run, they may be able to bridge the gap on the league leaders.
"We have to keep on going and try and win all our games because we know United are in the top spot," he tod City TV in the wake of the 2-0 win over Chelsea on Sunday.
"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."
