Toureâ€™s representative said this week that the midfielder had achieved all he can at City and needs â€śnew motivations.â€ť
But Mancini said: â€śEvery day we have a new challenge here, every day.
â€śIn 2Â˝ years we won the FA Cup, the Premier League, the Community Shield.
â€śNow we need to win another cup, another Premier League.
â€śWe need to work more for this challenge. I think Yaya thinks that, like me, like the other players.
â€śI am happy that Yaya wants a new challenge because I also want a new challenge, I want to win the next game, the next game in the Champions League, everything together.â€ť
Asked if he fears Toure will go, Mancini replied: â€śNo, absolutely.â€ť
