It seems like Xabi is trying to use a very good strategy for his team when they are unable to fight against bigger teams, at least holding out for a draw rather than losing and this strategy is like Xabi attempt to try to stabilize Leverkusen performance so that it looks consistent without losing but still gets points even if its only 1 point. and what I think at the moment is that as long as Leverkusen does not make mistakes that result in losing points, this team is still worthy of getting the bundesliga title and I admit that Xabi has actually studied since last season what the strengths and weaknesses of this team are to improve and maintain its performance to remain consistent at the top of standings this season.
Xabi applied very impressive tactics for Leverkusen. It is proven that Leverkusen is in the top (1st place) of Bundesliga standings. His tactics are also unique because he doesn't rely on the attackers only for scoring goals. In some matches, we can see that the goals were made by defenders and midfielders. But I think Xabi needs better attackers to make Leverkusen be more productive in scoring goals. I hope he is considering to sign top attackers in January transfer window.
So far, Leverkusen seems quite stable. They only got 2 draws and never got a defeat, the rest they won all the matches. If Xabi can keep the consistency of Leverkusen performance until the end of the match, Xabi can win his first title in Bundesliga as a coach. I really hope it can happen, so he can be a proper candidate of Real Madrid coach in the future.
In Bayern Munich they have many famous players and superstars like Kane and some other players in this team that's why they are in the top of the table, also Bayern Munich invested too much money in the team but Leverkusen is just on top of the table because of their coach Xavi Alonso and he is the only advantage get they have in this team.
