The fatigue mentioned by Freund stems from a relentless schedule that saw the record German champions playing every three days across the Bundesliga, DFB-Pokal, and Champions League.
This heavy workload coincided with the emotional toll of their narrow semi-final exit from Europe at the hands of Paris Saint-Germain, which ended their hopes of a continental treble.
The lingering effects of that European disappointment were evident against Wolfsburg, where Bayern struggled in the first half and relied heavily on 22-year-old goalkeeper Jonas Urbig. The youngster, standing in for Manuel Neuer, produced four magnificent saves to keep the scores level before a late flight back to Munich allowed the players to begin their collective recovery period.
