The Spaniard was thrilled at the way his side performed against an "incredible" Borussia Monchengladbach side in their 2-0 win on Friday
Goals from Mario Gotze and Thomas Muller secured victory for the leaders, who became the first side to win 15 of their opening 17 games in the Bundesliga.
Friday's victory moved Bayern on to 47 points, another record at the halfway stage of the season, and 10 clear of second-placed Bayer Leverkusen.
Guardiola was thrilled with the way his side coped against Monchengladbach, who sit third, and had boasted a run of eight wins from nine at home prior to the match.
"I am pleased for the team," he said. "I believe we took a big step forward towards defending our title.
"We played well against an incredible opponent. It is not easy to win here. We controlled the game.
"On Wednesday (at Stuttgart) we have a great opportunity to extend our lead with another three points."
