Manchester City's 3-1 loss to Chelsea in the Premier League on Saturday was their first defeat at home after taking the lead since 2009.
Pep Guardiola's men could not believe their luck when Gary Cahill acrobatically opened the scoring for them before half-time.
However, they were powerless to resist the Blues's fightback in the second half as Diego Costa, Willian and Eden Hazard led an impressive comeback.
