Bayern often used a 4-2-3-1 formation under Jupp Heynckes, winning the Bundesliga, Champions League and the DFB-Pokal last season.
Guardiola, however, played a 4-1-4-1 system against Borussia Dortmund in the Super Cup defeat at Signal Iduna Park, and Ribery believes the fresh approach will keep Bayern ahead of their rivals.

"The new system makes our game even harder to second-guess. We can change tactics mid-match or switch a few players around to give the opposition even more trouble."
While the Bundesliga is the team's priority, Ribery believes a strong showing in the Champions League is also imperative, particularly now that he has tasted success in Europe's biggest club competition.
"It was an unforgettable experience. I woke up happy every day on holiday, just thinking back to our Champions League triumph," he continued.
"The holidays were just the job to recharge the batteries. We're well aware that every team we play are going to be even keener to get one over us - because what feels better than to beat the treble winners?
"We want to win the Bundesliga again. That's our priority, to show again who's top dog in Germany. Furthermore we want to go as far as possible in the Champions League again."
Bayern wlll get their Bundesliga defence up and running against Borussia Monchengladbach on August 9.
Ribery has made 237 appearances for Bayern in six seasons, scoring an impressive 80 goals.
