However, the City boss is adamant that the title race is still over.
"It's finished," Mancini told Sky Sports News.
When asked whether he thought United could drop points against Aston Villa or Everton in their next two games, the Italian said: "It's not important now. We should continue like this. We should score, we should win if possible."
City's next match comes a week tomorrow when they face struggling Wolverhampton Wanderers before the Manchester derby on April 30.
