The Bavarians will be hoping to bounce back from their surprise 2-0 defeat to Borussia Dortmund in the German Supercup with a victory in the cup, with Arjen Robben perhaps involvedBayern Munich begin the defence of their DFB-Pokal title with a trip to third-tier side Preussen Munster on Sunday.
Goals from Arjen Robben and Thomas Muller handed Bayern a 2-0 extra-time victory over Borussia Dortmund in last season's final, earning the Bavarian giants their second successive cup crown.
But the 2014-15 campaign did not get off to the best of starts for Bayern as they fell to a 2-0 defeat at the hands of Dortmund in the DFL-Supercup on Wednesday, though they will be expected to cruise past inferior first-round opponents in this game.
Preussen have won just one of their four matches in the third tier so far this season but will be relishing the opportunity to pit their wits against the Bundesliga champions in an eagerly awaited tie for the hosts.
It would be no surprise to see Guardiola make full use of his squad for Sunday's fixture, which comes just five days before the Bavarian giants commence their league campaign against Wolfsburg at the Allianz Arena.
One of the players who could come in is Robben, who was named as one of three nominees - alongside team-mate Manuel Neuer and Cristiano Ronaldo - for the Uefa Best Player in Europe Award earlier this week.
The winger made it to the semi-finals of the World Cup with Netherlands, meaning that he was late in rejoining his clubmates for pre-season training.
Bayern's preparations have been dealt a blow after Javi Martinez tore the anterior cruciate ligament in his left knee during the Supercup, ruling him out for several months.
