Pep Guardiola's side earned that horror stat during their 2-0 defeat to Juventus in the Champions League on Wednesday evening, as their uncharacteristically rough patch of form continued.
Dusan Vlahovic and ex-Leeds star Weston McKennie fired the home side to victory.
As a result, Man City have now conceded 21 goals since the beginning of November in all competitions.
That's the most of ANY side in Europe's top five leagues.
The stat is even more mind-boggling considering Guardiola's side are the reigning Premier League champions.

Incredibly, since the beginning of November, Man City have won just one game.
That came in the form of a 3-0 victory over Nottingham Forest in the Premier League exactly a week ago.
In that barren period, they also lost 4-1 to Sporting Lisbon in Europe.
Any hopes of a top eight finish in the Champions League have been dashed now after their second defeat in a row - and Guardiola and co will have gone from looking up to looking over their shoulder.

The 2023 Champions League winners have slumped down to 22nd in Europe's top flight.
They are just one point and three places away from dropping out of the play-offs and being eliminated.
Not all hope is lost for Guardiola and co in Europe, with two fixtures after Christmas to play.
They face Paris Saint-Germain on January 22 before hosting Club Brugge on January 29.
PSG are also in a precarious position, sitting one place below the play-offs but just one point off City. Club Brugge sit above them both in 19th.
Man City will be hoping to be in a much better position by the time those fixtures roll around to avoid being knocked out of the competition.
They are currently enduring their worst run since 2006 after winning just one game in 10.
And City have now incredibly suffered seven defeats in those fixtures.
