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.
