Guardiola, who has remarkably faced criticism despite an unbeaten start to the Bundesliga season, was measured in his assessment of City.
"We played better, we won, but the football is special.
"I am lucky to be here to train these players.
"It is nice for the team to come to this country, where they love football so much, and play like we did today."
The victory took Bayern clear at the top of the group and, even after just two games, probably leaves City in a battle with CSKA Moscow for second place.
Guardiola remains convinced City will go through.
He said: "I said it yesterday and nothing changed my mind.
"They are going to qualify and will be a tough opponent for the next round, but I can only talk about my team and what they did."
