This is the process that Xabi Alonso went through from a player to now a coach, and Xabi succeeded in applying what he adopted and learned to his team well so that Leverkusen became the best currently in Germany, and most importantly Xabi was able to manage the mediocre club Leverkusen until they became the rulers of the Bundesliga. This season is completely unpredictable, his arrival there makes the Bundesliga competitive, competing to become Bundesliga champions.
In my opinion, Xabi was successful this season by winning the Bundesliga and Copa Pokal. It's extraordinary, because Leverkusen hasn't won a trophy for a long time, but Xabi's arrival at Leverkusen made Leverkusen fans smile again.
Xabi Alonso has proven his toughness so far not only as a player, even being a coach he is able to give achievements and surprises to the team that recruited him so far, his experience playing is of course no doubt and even he is able to become a mainstay for three teams that are in three different leagues so far, Liverpool, Munich and Madrid are certainly the teams he has helped win, His ability to play in the midfield position so far has certainly been successfully applied at Leverkusen this season which does have a midfield and defense that is quite good in every game they play.
Xabi Alonso has played in 3 different clubs and leagues over the years and of course he understands quite a different style and scheme of play different from every coach who has managed the team so far, Liverpool, Madrid and Munich are the teams he has helped win so far and I think he took a lot of knowledge from every coach who has managed all three teams so far and applied it to Leverkusen this season so that it is It can be seen that Leverkusen game is amazing.
