A thrilling Manchester derby was decided by a 92nd minute free-kick by Robin van Persie but the game was also notable for City's superb second-half fightback. The Citizens came back from two goals down and regularly threatened to escape with all three points in the home fixture.
Ultimately, the Red Devils secured a crucial result that sees them go six points clear of their city rivals. Mancini was dismayed that his side could not at least grab a draw as he felt his team had been the better side overall.
He hailed the quality of the players in his squad and believes they have it in them to catch up with their rivals over the remainder of the season.
"United have more experience but we have a much better team and play much better football," the Italian was quoted as saying at a function in Italy on Tuesday.
"Six points is not a big difference with 24 games still to play.
"We need to try to win five or six games in a row to try and reduce the gap.
"Even though we lost on Sunday, we showed that we are a really strong team and can win the title again.
"We were unlucky. We dominated long spells of that game - and did not deserve to lose.
"The Premier League is the best campaign in the world at the moment and as we know from winning last year, you can lose a game in the last second."
City skipper Vincent Kompany, who had to walk off with a calf injury in the game, called on his squad to give that extra ten percent this season as the same level of effort as that in the preceding season would not be enough to help them retain the title.
"The message was very clear for everyone at the start of the season - we can't sit back and just expect the success of the last campaign to land in our laps again," Kompany said.
"An acceptable minimum is unacceptable because we have the ambition to improve on our achievements last season and do better again.
"That's our aim and what we work towards every day in training.
"We've learned a lot from winning the title but I still think there is a lot of room for improvement."
And he pointed out that teams have learnt to not underestimate his side and have now taken steps to prevent City from playing their game.
"Teams tend to sit back a little bit more and wait for you to take the game to them - then try and catch you on the counter-attack.
"Teams may have more respect but they are not naive and that makes each game a bit trickier. But it's an honour to be defending the Premier League, so you have to take everything that comes with it."
"In my mind, there is no difference other than we now know we can do it so if we apply ourselves correctly we can win it again."
Within the same interview, Mancini had also declared that Mario Balotelli was not up for sale and he would also not be seeking to bring players from Serie A into the City fold in the January transfer window.
