Toure, whose side are only three points behind United and with a superior goal difference, has described next Monday's derby with their city rivals at the Etihad Stadium as one of the most important games in the club's history.
"United's result (4-4 against Everton) was amazing. It was an unbelievable day for us with United dropping points at home. For me, it was strange," said Toure. "We found out about it on the bus on the way to Wolves. It was quite unbelievable and we now have to try and take advantage."
He added: "We did the first part by beating Wolves but we have to settle down and continue to work hard because United still have three points more than us.
"We have to play them at home and, if you look at the record of United, they are very strong away and it will be a very difficult test for us.
"I think this year the club need to win the cup (title) and it will be difficult.
"But we need to win this derby because it will be one of the most important games the club have had."
City manager Roberto Mancini continues to play down his side's chances despite United's unexpected setbacks, but he is happy with the improvement in his side compared to last season.
Mancini said: "We have another chance but they have a bigger chance than us at this moment. After the derby, the games United have left are not as difficult as the ones we have to play.
"We have improved a lot from last year. This is important if you are building a team. If you win, you are happy, for sure. But if you are improving, then that's important."
