For the upcoming game against Dortmund he has four players you could classify as defensive to choose from, for 6 positions. You need to include youth players Krätzig and Pavlovic, or Bouna starr to even make a starting eleven. You can blame Tuchel for details but idk how much that matters when there is the glaring lack of any depth in the squad, combined with an unfortunate amount of injuries. Though that hasn’t stopped Bayern from sacking Nagelsmann, so who knows
