I am also curious about what will happen to Bayer Leverkusen after Xabi. It is not clear whether they will be successful next year. However, what Xabi achieved there really deserves appreciation. As a result of being so successful, he became the coach of Real Madrid today. Real Madrid saw his success in Leverkusen and brought him to the team. Now, what the Dutch coach will do with Leverkusen will be monitored. If he fails this time, the big teams may not choose him again.
Erik Ten Hak to be a coach who will handle Leverkusen next season and they will start a new chapter after Xabi Alonso left.
It is not easy to achieve the results as given by Xabi Alonso but it is worth giving an opportunity for Erik Ten Hak to handle Leverkusen next season.
Next we can see how Leverkusen uses the transfer market to get the players needed by the Dutch coach.
Still too quickly saying failed even though he could not succeed in becoming a coach at Manchester United, but who knows in Leverkusen, Erik Ten Hak can give better results.
I don't find Dutch managers successful. Cruyf, who is long gone, may have been successful, but other than that, I don't know of any Dutch managers who have left their mark on world football.
I don't expect Erik Ten Hak to be successful at Leverkusen after Alonso either.
It may be an ambitious statement, but I even think he will be removed from the team before the mid-season transfer window.
