I agree with you. Bayern Munich's elimination from the DFB Pokal is good for Bayern Munich. Now Bayern Munich will be able to focus more on the Champions League matches. If the schedule is too busy, it becomes very difficult to maintain a good performance. Bayern Munich's performance in the Champions League matches is very irregular. The team is in 13th position in the points table. Bayern Munich has lost two out of 5 matches. Winning the Bundesliga title will not be difficult for Munich. However, doing well in the Champions League is very difficult for Bayern Munich.
Every cup is important to a team, so i don't know why Bayern Munich's elimination from the DFB Pokal should be considered as a way to make Bayern concentrate in other competitions. If it's about the Champions league, Bayern Munich should just forget it because they won't get to anywhere. Their focus should be on the Bundesliga and not the Champions league because they still have a long way to go and they will definitely meet bigger opponents that can stop them along the way, unlike the Bundesliga where they play with regular teams within the league and they easily understand their pattern of play. Even though Bayern is topping the table with 4 points but i think they are not safe considering the force of Eintracht Frankfurt who is second in the table so Bayern needs more consistency before they can be comfortable at the top of the league table.
