Xabi Alonso's success in managing Bayer Leverkusen in all leagues is a threat to big clubs in the Bundesliga and Europa League. Xabi Alonso's intelligence is quite questionable this season because Bayer Leverkusen always wins big enough in their last three matches, in the Bundesliga and Europa League. Of course this is a serious threat for Bayern Munich in winning the title. Maybe last season Bayern Munich always dominates the Bundes League, even though they have expensive players like Harry Kane, but that doesn't have any impact on Bayern Munich, because Bayer Leverkusen is at its best so it is also very impossible for Bayern Munich to dominate the German League this season.
In my opinion Bayer Leverkusen will not lose their place at the top of the standings as long as they continue to play consistently and have the ambition to win the title this season, even though Bayern Munich has expensive or experienced players but that cannot change anything at the top of the standings.
Xabi Alonso has shown success since the start of his arrival as Bayer Leverkusen coach and has been quite successful so far.
What Leverkusen has shown so far means that they will be taken into account in the Bundesliga and also the Europa League, Leverkusen has strength and they can maintain consistency so their percentage of being able to win the title is quite large this season and besides that Leverkusen can also Taking advantage of Bayern Munich's inconsistency so that they continue to maintain their position at the top of the standings until the end of this season.
