Xabi Alonso has the opportunity to defend his title again, but repeating his streak without defeat seems unlikely to happen again. Bayern Munich has indeed changed coaches, but it looks like Kompany will have difficulty bringing Kane to success. Alonso just needs to polish his squad a little so that it is fresher when entering the new season. However, Alonso is clearly under pressure if he continues to be compared to his achievements this season.
However, remembering that this is something that is not easy for Leverkusen to repeat, of course there is a possibility that Leverkusen could lose in the Bundesliga next season even though Leverkusen is still the favorite to win the Bundesliga. And the difficulty of this could arise from the fatigue of Leverkusen players because next season the team will also compete in the Champions League which is generally very physically draining for players.
Yes, though their participation in other competition is indeed going to be a deterring factor to not likely be the Champions, but same as their major contenders this season, Bayern Munich and Stuttgart will also be present in more competition as Leverkusen will do, so If the squad is left intact and xavi Alonso is still their as the head coach, I don’t even think Bayern Munich is ready to outperform Bayern Leverkusen next season and lift the trophy,and even Stuttgart who finished second in the table last season.
I think Bayer Leverkusen winning the league next season is under 70% this is because there is no news of any of their player who has left the club at the end of the season even though they have not added a new player yet in the team but the availability of them manager Xabi Alonso still means a lot to the team and it will give them an edge over their biggest rivals Bayern Munich because they have a new coach who will take some time to master the players before chosing the write tactics and formation that will be best for the team.
Bayer Leverkusen involvement in other competition especially the champions League will surely affect their performance in the league but since their opponent Bayern Munich and Stuttgart is also playing in the champions League I think they will still have the advantage of winning the league because they have a more balance team than Bayern Munich so far.
