Speculation about Xabi Alonso's future is indeed very interesting for us to follow, currently Xabi Alonso's ability to bring Leverkusen the best level certainly raises interest from many European teams to recruit him as a coach next season, including two clubs where he has had a career as a footballer namely Munich and Liverpool, currently we have not heard confirmation if Alonso will leave Leverkusen next season although the two clubs have stated His interest in making Xabi Alonso a coach.
From the source you provided, I actually assess if it is still a prediction of Xabi Alonso's future, in the news said if choosing between Bayern Munich and Liverpool of course Xabi Alonso would choose Bayern Munich because the Bundesliga is easier for him than the Premier League, besides that he claims it will be very difficult to replace the role and continue the glory left by Klopp at Liverpool, What Xabi Alonso said is certainly a sign, but I don't think it's a certainty if Xabi Alonso will really want to coach Bayern next season.
This season, there's been a switch in the dominance that occurs in the German league, the professor Xabi is one key threat to Munich who's in time past being the head and leaders of the league. Even though last season, there's been a trail behind from Dortmund, comparing all the years, only Leverkusen have been overtime been able to maintain the difference in standings on the contention battle. Tuchel knows that a serious tussle laid ahead and as the season keeps drawing to an end, there's been hope for a greater chance to create growth opportunities too.
I'd have loved to see how the end of the season will look like for the German clubs as it's highly expected that unlike Dortmund, Leverkusen would make the big difference since so far, Munich has failed in making good names for themselves. Sadly though, Tuchel's stay in the club is seemingly threatened, his days are actually numbered and it's understandable that the management would want a switch for the coach position as they expected him to be better considering how much effort his put in recent times and even with flaws, they need not to keep overlooking it as it's unending. Well it'll only task them to find a proper hand that'll replace Tuchel's as so far they need not to take their chances and cause this to continue unto the next season.
Even though Leverkusen with Alonso have been impressive in all rounds and it's surprising that they're now better than some already grounded teams. It only means that Xabi has a unique managing quality which can be of essence in bigger teams too. I believe he's still got good plans for the German team, which will still be manifested good. Well it'll only be fair and an added advantage to the German club if their hit maker coach stays the next season with them to keep up with the positive differences he's trying impart to the club.Alonso was quested for by the counterpart German team, Munich and they've been able to have his preference. Well, hopefully he'll be able to take them out of the state they are. His records are speaking for him and so it's understandable that they see him as a proper prospect for the job ahead in the club.
