City's hopes of retaining their Barclays Premier League title appear slim with Manchester United once again 15 points clear at the top of the table.
Mancini has regularly cited the failure of his forwards to match the standards of last season as one of the reasons for the champions' faltering title defence.
City have found the net 50 times in their 27 league games to date, 19 behind their tally at the same stage last season and 18 less than United this term, although they have played a game more.
It is an issue City are expected to address in the summer but Mancini does not necessarily need an abundance of goals to get back into the title race.
The Italian said: "I hope that we can win the next 11 games 1-0 if it is possible because 1-0 is enough if you don't concede a goal.
"But it is impossible that you don't concede a goal every game.
"It is clear, if we are missing 15 or 16 goals now from last year, it is too much because 10 goals are probably six or seven points.
"This is the difference."
