The Citizens scored another late winner on Tuesday night, this time against Bristol City in the first-leg of the Carabao Cup semi-final.
And two-time Premier League champion Toure believes City's resilience is helping them dominate this season.
"In these kind of games, we have to play two legs to try to win," he told the club's website.
"That's the most important thing.
"In the end, there was one minute left. When you win games consecutively, it can happen – the kind of games where we draw until the last minute. To continue to score like that is fantastic.
"We have a big mentality. Mentally, we're very good. We keep going, keep working hard, trying to continue creating chance after chance… We believe in ourselves. All of the lads are doing really well.
"In the next game, we have to win again to try to go to the final. We don't want to draw the game – we just want to win so we will be more secure."
