Bayern Munich big win against Union Berlin still had a good impact on the team, even though it didn't have any impact on the Bundesliga standings. Because after all, basically Bayern Munich still have to maintain or shape their morals and mentality to be better, of course to prepare for their Champions League semi-final match which they will still play against Real Madrid. Therefore, Bayern Munich's big win yesterday remains a good result and/or basis, because then Bayern Munich's morale and mentality will remain intact until they play in the Champions League semifinals later. So yes, basically it will always have a good impact, because there is still a chance for Bayern Munich to get good results in other competitions such as the Champions League.
On the other hand, regarding Union Berlin performance this season, they have experienced quite a serious decline, where last season they managed to finish in the top four of the standings but are currently two levels above the degradation zone. Union Berlin also has the potential to be trapped in the red zone because they are only 2 points adrift of 16th place, with 4 matches remaining in the future where they must immediately recover.
Towards the end of the season and overall the Bundesliga only has 4 matches remaining, I think in the Bundesliga all competition has finished. Now Bayern can completely shift their focus to the Champions League, even though their chances of reaching the final round are lower, Tuchel is still required to work optimally to maintain the remaining hopes. Everything will be improved next season, and this season Kane has not been lucky enough to taste his first domestic trophy.
