If Bayern Munich are going to have these two players absent in their upcoming match against inter Milan, forget it Bayern Munich are more likely to lose the match it doesn't matter where they are playing the match. Inter Milan is not an average team just hope you know that. They are topping the Italian league same way Bayern so topping the German Bundesliga. Davies and Dayot Upamecano are big names in Bayern Munich dressing room and having these two players absent at once it's a big factor that has the potential of making Bayern Munich lose this match. The only thing that Bayern Munich should be praying for right now is that Inter Milan should not have their full squad as well. Inter Milan is not a small team. We might think that Davies and Dayot Upamecano absence is nothing, but I believe that Vincent Kompany is already sweating on their absence.
The absence of two players will affect Bayern Munich's performance in the Champions League because even if Bayern Munich will have a complete squad and Inter Milan have complete squads, the outcome of the game will not be that easy to predict, as both of the teams are very strong in their various domestic leagues.
But still, as this is trying to happen to Bayern Munich, they will not be reliant due to the absence of two of their players, which might give Inter Milan a chance of winning, but it might still not be sure for Inter Milan to win, as it will be a home game for Bayern Munich, and we all know they will not like to lose a home game, so they will definitely bring up a new strategy that will favour them in winning against Inter Milan in the game.
