Pep Guardiola’s side booked our place in Round Five with the hard-fought success over the League Two outfit.
Alfie Dorrington’s own goal inside the sixth minute gave the hosts at the Etihad Stadium a strong start, and it looked likely a comfortable afternoon for the Blues would follow.
However, the Ammies grew back into proceedings in what developed into a well-contested tussle for cup progression as City looked somewhat disjointed.
The boss then turned to his bench in the second half and introduced Antoine Semenyo, Marc Guéhi, Nico O’Reilly and Rodri in the second half in the search of a precious second.
And it arrived with just 10 minutes remaining when Guéhi poked home his first for the Club from close range.
