Xabi Alonso made an excellent decision to continue with the team next season. Leverkusen will play in the next Champions League, they will need a coach like Xabi Alonso because he has played in major competitions such as the Champions League. I can't wait to see the club compete with the clubs from other leagues, as we have seen how they competed with Bayern Munich for the Bundesliga title race this season. You're right, they need to add more players next season, so they shouldn't be eliminated so easily, because they will face difficult challenges in the next Champions League if they meet a major team like Real Madrid or Manchester City, we don't know if their current players will have strength to play this way next season.
It's true that it was quite a wise decision that he took. And Leverkusen also looks like they will become a new challenger in the UCL next season. And apart from Leverkusen, it looks like there will also be a new challenger from Laliga, namely Girona. Girona this season has also become a club that has surprised everyone in the league. Although Girona's performance in Laliga is not as good as Leverkusen in the Bundesliga. but Girona also has a chance to go to UCL.
Regarding Xabi Alonso, he knows which is the best path for him to take and Leverkusen is indeed the right answer.
