While the Champions League winners earned a bye through to the semi-finals, Al Ahly reached the last four with victory over Al-Duhail.
In a season where games are being played at an unforgiving pace, Hansi Flick may feel that his Bayern squad could have done without the trip to Qatar.
Nevertheless, the Bundesliga leaders are motivated to win their sixth piece of silverware since Flick was appointed as Nico Kovac's replacement in November 2019.
Ahead of Saturday's fixtures, Bayern hold a 10-point lead at the top of the standings, giving Flick freedom to use his best players in this competition.
The German side are looking to replicate their success in 2013 when they beat Guangzhou Evergrande and Raja Casablanca without conceding a goal.
Like their next opponents, Al Ahly have not featured in this tournament for over seven years, and they will be ready to perform with little pressure on their shoulders.
As well as putting together a 32-match unbeaten streak in all competitions, the Egyptian side have also posted their best ever showing in the tournament.
The Red Devils have also kept nine clean sheets in 11 games, a record which ensures that Bayern cannot afford to be complacent against well-drilled opposition.

With one eye on the final, Flick may take the opportunity to rest a number of his key men for this contest.
Barring any fitness issues, Mosimane could name the same Al Ahly XI which started the game on Thursday night.
Al Ahly possible starting lineup:
El Shenawy; Hany, Banoun, Ashraf, Maaloul; Fathi, Al Sulaya; El Shahat, Magdi Katsha, Mohamed; Bwalya
Bayern Munich possible starting lineup:
Neuer; Pavard, Boateng, Alaba, Davies; Kimmich, Tolisso; Costa, Muller, Coman; Lewandowski
We say: Al Ahly 0-3 Bayern Munich
When taking Bayern's lack of preparation into account, Al Ahly will feel that they have the tools to trouble the German giants. Nevertheless, Flick's side should have far too much quality in the final third, giving them every chance of recording a routine win.
