The Spanish coach believes it's only logical that FCB have been slightly inconsistent so far as they are still developing as a team
The Bundesliga champions have been struggling to dominate games like earlier this season in the past few weeks, but Guardiola believes it's only logical they're not 100 per cent just yet.
"In my first year at Barcelona our performances had some ups and downs. We kept the level high, but stabilised our displays at that high level after two or three years," the 42-year-old stated at a press conference.
"Generally we always played better than our opponents.
"Now at Bayern, there is a new coach, there are new players. We need time to fine-tune things."
Guardiola then went on to discuss Bayern's 1-0 Champions League win over Viktoria Plzen on Tuesday and stressed that away games are always tough in European club football's elite competition.
"It was more difficult than the first game two weeks ago. I also clearly remember the games against Plzen we played with Barcelona, but this one was the toughest.
"Away matches in the Champions League are always difficult."
Bayern's win over Plzen saw them qualify for the round of 16 with 12 points from four games.
