Tuchel is more experienced than Xabi Alonso but Xabi has been gaining more experience with his team and seasons. Xabi can be considered as a new version of Tuchel when Tuchel built up his coach career with Dortmund.
What Xabi Alonso and Leverkusen have been showing since the last season is very impressive and they actually are improving themselves a lot. Beating Bayern Munich in this season is harder than the last season because since the summer transfer, they got a world-class striker, Harry Kane. It is what Bayern Munich did not have last season after letting Robert Lewandowski moved to Barcelona.
I really want to see Xabi Alonso and Leverkusen win Bundesliga because the domination of Bayer Munich in the league is so boring.
It is clear that Tuchel is much more experienced than Xabi, but that is not a strong reference that Tuchel will easily bring Bayern Munich to become champions this season. The reason is that Leverkusen under the guidance of Xabi Alonso has performed quite impressively, so it is very likely that he will keep Leverkusen at the top of the standings in the upcoming match. Apart from that, we see that competition in the second half of this season will be even fiercer, even tuchel, who has a stronger squad than Leverkusen, has big plans to get back to leading the standings.
In the Bundesliga this season, these two coaches are in the big spotlight in bringing their team to become champions this season. However, if Leverkusen succeeds in becoming champions this season, of course it will be a big change for the Bundesliga because Bayern Munich dominance, which has lasted for so long, will be broken by Leverkusen this season.
