But everything changed after the break as relegation-threatened Leeds put up a fight for their under-pressure boss Daniel Farke. They produced a spirited comeback and even believed in victory themselves but Foden diminished that, deciding the game with a brilliant finish from outside the area in the first of the 10 minutes of additional time.
The England forward scored the fastest Premier League goal of the season to give City the lead after 59 seconds, firing in first time after a cross from Matheus Nunes. The midfielder was denied a second goal by a brave block from James Justin, who threw himself in front of the ball from close range, and then by a super save from Lucas Perri.
Leeds could only resist the City dominance for so long, though, and the second eventually arrived from a corner, Gvardiol sliding in to stab home following Nico O'Reilly's knockdown, helped by some abject goalkeeping from Perri.
City had the bit between their teeth and pushed for a third before half-time but to no avail, with Bernardo Silva and Tijjani Reijnders having shots blocked and Perri repelling a strike from Nico Gonzalez, while O'Reilly headed wide.
Leeds came out for the second half with a double substitution and a totally different mindset and they immediately pegged City back. They fired out a warning minutes after the restart when Donnarumma patted a free-kick away only for it to land at the feet of Ethan Ampadu, with Reijnders making the block. One minute later Dominic Calvert-Lewin halved the deficit, losing the ball on the turn then snaffling it back off Nunes to strike. City's nerves began to set in and Leeds then won a penalty when Gvardiol rushed into a tackle on Calvert-Lewin and sent him flying.
Donnarumma guessed right to parry Nmecha's penalty but the rebound fell straight back to the German forward for him to tap in the leveller. The Etihad fell silent but when Foden buried the ball in the bottom corner after dribbling across the outside of the box, the stadium erupted and secured a valuable three points for Guardiola and his troops.
