Jack Grealish revealed that he and Riyad Mahrez both thought Kepa Arrizabalaga would get a hand to his cross that led to the Algerian's opener.
Mahrez scored the only goal of the game as City recorded a third successive win at Stamford Bridge, although they needed several substitutions to finally impose themselves on the game.
And two of those - Grealish and Mahrez - combined for the opening goal, which gave Manchester City the all important three points against a Chelsea side hampered by injuries early in the encounter.
