Micah Richards identified what he believed to be Man City's difference-maker in their 2-1 win at Leyton Orient in the FA Cup fourth round.
Pep Guardiola's side faced an early scare after Stefan Ortega's own goal gave the hosts the lead in the 16th minute.
However, a pair of goals in the second half from Abdukodir Khusanov and Kevin de Bruyne earned City a hard-fought win and booked their spot in the fifth round.
For the better part of an hour, City could not break through a stubborn Orient side, who were opportunistic on the counter-attack, and mustered up 13 shots against the champions.
