Saturday's 2-1 win over West Ham means City have now scored in 48 consecutive home games.
The man Mancini's team have eclipsed, Scot Peter Hodge, was responsible for steering City out of English football's second tier in 1928 and into third spot in the top flight two years later.
It is worth noting only twice prior to that had City done any better, and at that point had not won the first of their three league championships to date.
Roberto Mancini: "Records only matter when you win a trophy.
"With this one we do nothing.
"Our problem this year has been that we didn't score enough to win the title.
"Against West Ham we deserved to score four or five goals.
"This is my frustration for the season. We had chances to win at Tottenham last week and lost. And against West Ham we didn't score enough."
