Manchester City beat League Two side Port Vale 4-1 on Saturday at the Etihad Stadium to progress to the fourth round of the FA Cup.
The holders opened the scoring when Oleksandr Zinchenko's shot from range hit the outstretched boot of Leon Legge on its way past goalkeeper Scott Brown.
The visitors shocked Manchester City by pulling one back through Tom Pope after 35 minutes. David Amoo raced down the right and crossed for the striker to head past Claudio Bravo.
Sergio Aguero restored Manchester City's lead three minutes before half-time, tapping home Phil Foden's low cross at the far post for his 15th goal of the season.
