"I think that it was a good game, the last game," Mancini told Sky Sports after the 1-1 draw at Upton Park.
"We had a lot of chances to score a goal but I think a draw is the right result.
"After Wednesday we were disappointed because we had a big chance to get the fourth position.
"But that's football, I think that we worked very well this year."
Mancini also revealed that he needs to bring some new faces to Eastlands during the close-season for City to improve on their fifth placed finish this term.
"We improved from last year and now we want to improve for the next season.
"We have a chance to buy new players, to improve in pre-season. I think this year will be an important year for us."
"That we start together in pre-season is important for the manager and for the players and then we must buy new players and after we can say where we can arrive next season."
