Its going to cost them fortune to get Xabi Alonso and as of now, I bet he is a Top tier 1 coach that any team would be willing to hire. Imagine winning (almost) Bundesliga with Bayer Leverkusen against the all season dominating team like Bayern Munich then after that he pick a team like Liverpool that has alot to do for their next season after Klopp leave
He will has better chance on sticking with a top club in Bundesliga like Bayern Munich rather than taking chances for now. He still has plenty of years ahead of him if he wanted to get some challenges though
I don't know what's the plan of Xabi Alonso for the next season. We have some rumors about him, Liverpool and Bayern Munich are 2 teams to compete for signing him. But it is no clear which offer Xabi will consider.
It is indeed inseparable because after all it is very natural for Xabi at this time if it becomes a struggle because his condition in the last 2 seasons at Leverkusen is so impressive that surely some big clubs glance at the performance that Xabi is doing now.
Currently, Liverpool and Bayern are also quite reasonably associated with Xabi because of the previous attachment between the two clubs with Xabi already established when he became a player who played an important role in Bayern's midfield and also Liverpool so the chance to be in these two clubs will definitely be very large especially with Liverpool who lost their coach next season and the possibility of Bayern who will fire Tuchel if this season Leverkusen become champions and stop Bayern's dominance that has been established since 11 consecutive seasons. Then there will definitely be some changes that Bayern will make but for Xabi's future we still have to continue to wait at least until the end of the season because after all the situation becomes unpredictable in the end.
