Guardiola said that there is plenty of room for improvement in their play, but was pleased how quickly the players started to understand his philosophy.
"From the first contact I had with FC Bayern, I knew within seconds - you have to do it," Guardiola told the club's official website. "I did not want to pass up the opportunity to work here with this great team that the club had put together in the past few years. Had I said no, I might not have been asked again.
"It's not all that important to be top of the table in October, but it's always nice to be there. All that matters at the moment is that we get to grips with our playing style. It's an on-going process and the performances against Manchester City and Bayer Leverkusen show we've already reached a decent level that we want to maintain in the coming weeks.
"I'm honestly really surprised how quickly the players have taken my ideas on board. We definitely need more time, but the level is already very, very high. I'm happy how we're playing."
Guardiola joined the club in the summer, taking over from treble-winning coach Jupp Heynckes.
