City came from a goal down to eventually sail past a determined Burnley in the FA Cup third round.
The Blues had gone in at the break trailing to the Clarets but dug deep in the second period with two Sergio Aguero goals in two minutes swinging the game City’s way.
Further efforts from Leroy Sane and sub Bernardo Silva sealed a hard-fought, but ultimately impressive win.
Afterwards, Guardiola praised Aguero, saying: “I have to say it’s an honour for me to have Sergio under my command..
“He’s the type of player who always wants to play. Sometimes he is sad if he isn’t playing. I want him to be happy.
The quality he has is amazing. We have other players who can score, but he is the type of player who in a matter of seconds, can score two goals.
“If we want to win something, he is an essential player for us.”
