I don't see any reason why Bayern Munich should rule out the DFB Pokal as a target this season. Kompany fielded his best team in this game, but Manuel Neuer 17th-minute red card meant they struggled to match Leverkusen strengths. Leverkusen were very fortunate to have managed to eliminate one of the strongest candidates to win this championship, but Xabi Alonso also needs to maintain his team's performance because there are still other competitors who are performing well in the Bundesliga. Now, Bayern Munich can focus more on the Bundesliga while Leverkusen must try to perform optimally in the DFB Pokal, while in the UCL their chances are still grey.
Every competition is important for every team that is already in it, including a team as big as Bayern Munich, but losing a main goalkeeper who is often relied on by the Bayern Munich team will certainly have an effect on the course of the Bayern Munich vs Bayer Leverkusen match in the DFB Pokal competition. Because this time it can be said that Bayer Leverkusen was luckier because there was a red card for Bayern Munich's main goalkeeper so that Leverkusen was able to win the match even though it was not by a big score.
