I feel like they are going to make a solid start by scoring at least a few goals. The Bundesliga starts quite late compared to other European teams though. Bayern Munich are going to play their first game on August 25.
Yes, the Bundesliga will start the new season at least one week later than other major European leagues. With these differences, it means that Bayern Munich still has one friendly match and will also start with a match in the DFB Pokal. Thus, it is possible that Bayern Munich will start the Bundesliga season with more thorough preparation. Because after all, Bayern Munich's opening match is also the fact that Bayern Munich will play away against Wolfsburg which is certainly not easy at all.
Indeed, I believe that Bayern Munich remains the favorite team to win against Wolfsburg later, but still, I personally would not consider it to be an easy match. Therefore, even though Bayern Munich may still look fine in these pre-season matches, basically matches in official competitions will be more difficult. Because they also both want or target to get points, of course to be in a good position in the standings.
