Mancini believes Liverpool are still in the race for the fourth place, along with Tottenham and Aston Villa.
“If we win seven games I think we go, but I think it will be difficult,” said the City boss.
“If we want to get fourth spot we must win always. It will be important that we win at home and away.
“In the last three games we have won in London twice, against Chelsea and Fulham, and drawn at Sunderland.
“It is important we have the same spirit away as we do at home.”
City face Everton in a key game on Wednesday night.
He added: “I think Liverpool are a strong team with a good manager and I think we must fight with them, Aston Villa and Tottenham. I don’t think Liverpool are out.
“We always hope the other teams lose, but it is important we do our job very well like at Fulham.
“Everton are in good form and they work very well on the pitch and it is a crucial game for us. If we win tomorrow we will have more chance [of finishing fourth].”
