I don’t think Leverkusen will not have this kind of performance this next season, Leverkusen can not do unbeaten performances next season in the Bundesliga league, and it will be very difficult because next season is going to be tough. After all, many teams are ready for them, most especially Bayern Munich ready for Leverkusen next season so that they can revenge what Leverkusen did to them this season, Leverkusen will be performing in the champion league next season and will also make them focus in the champion league next than any other league, Xabi Alonso will have to advise his players to perform well in every league that they will play if not they won’t have a good season next season because there will be a lot of pressure on them.
Actually, we don’t really know what will happen next season, and we don’t know how their performance will be next season, so therefore, I won’t predict yet because, despite the fact that Leverkusen came from knowing where and started shining, they can still do it next season because both teams, Bayern Leverkusen and Bayern Munich, already know each other's weak points, so next season is going to be tough, and because Bayern Leverkusen are going to look for another trophy again.
About Bayern Munich, Kompany is going to be Bayern Munich's coach next season, I think the Kompany got fired from the team he was coaching before because of his poor performance during his coaching and now Bayern Munich wants him to be their new coach, Kompany is still a young coach who can help the team but I’m still thinking is he going to make Bayern Munich win trophies next season? Kompany needs to have a good plan on how to use Bayern Munich players if not he will end up like Thomas Tuchel and Bayern Munich will send him and way without not thinking twice.
Getting a new coach for Bayern Munich doesn’t mean they will come back with full power and get their performance back, and you know that when you get a new coach, the new manager will have to study the squad very well and know how the players are playing, so this may slow their progress in the season. However, age is not going to be what determines how he will manage the team. Let's see how Bayern Munich will do next season because the Bundesliga is going to be tough next season.
