I also want him to stay in Leverkusen for another year because everyone sees his success this year as a coincidence. If he stays in the team next year and shows similar performance, he will show everyone that this is not a coincidence, but talent. Xabi was a great player and now he is a great coach. Leverkusen owes him a lot.
The performance and consistency shown by Leverkusen at this time is really very extraordinary and even they can be the only team that can be at the top of the table without defeat among the top 5 European leagues this season, Alonso ability to make Liverkusen performance increase dramatically this season certainly makes many big clubs very interested in recruiting him as their coach next season, and I think it will be very difficult for Leverkusen to be able to keep Alonso next season, especially now the offers coming from Munich and Liverpool which of course are very difficult for Alonso to refuse.
Leverkusen will certainly play in the Champions League next season, but it will certainly be very difficult for them to maintain their form next season as it is this season, because after all Leverkusen management will most likely lose Alonso who may move to Bayern or Liverpool, besides that it will be very difficult for Leverkusen to keep their star players if an offer comes from the team It's big in Europe and I think next season Leverkusen will be very difficult to maintain their current success in both the league and Champions League.
