I don't see Leverkusen as a team that will be a problem to bayern munich again come next season because with Alonso leaving for Madrid I will say that it's an end of era and Leverkusen under a New coach will really struggle so to win I see the days of a one horse race for the bundesliga back
But Xabi Alonso isn't leaving, he has already left Bayern Leverkusen for Real Madrid. I know you already know his left but you're making it sound as if his still at Bayern Leverkusen from your statement. I also agree with you that Bayern Leverkusen wouldn't be that much of a threat to Bayern Munich at least this coming season because they lost some players already and the coach that's about to take over is also a new one. I don't think he will adapt so easily even if he does adapt easily, Bayern Munich will not just watch him take the trophy because I believe they will still want to defend it.
I think every viewer of the football knows that Xabi Alonso leaves the Bayern leverkusen and currently he is coaching the Real Madrid's player. I think making a win is not enough just to have a good coach, the coach plays an important role. But in my opinion a single part of any team can't make a win as an individual. The players the coach and the management when these all three pillars will connect deeply to each other then definitely your win is not so far. Maybe the coach Xabi Alonso will perform more accurately and in a more satisfying way than at Bayern Leverkusen. So i think we should avoid making opinions on just the base of our personal thoughts. And yes, the final remarks will definitely be based on the entire performance.
