Xabi Alonso has to be praised. He has made the team perform well even when he doesn't have the best of players for service. But that's what coaches are supposed to do, unlike a certain someone like Ten Hag
Xabi Alonso was able to see and develop the team's collective game so that it was able to create a strong game and was able to remain unbeaten to date. Sometimes a coach just needs to find a strategy that suits the squad he has. Or the coach could create a new strategy that is suitable for the team to use. For me, Xabi is great because he is able to create excellent chemistry for Leverkusen. Don't talk about Ten Hag here because maybe there is a problem that befell United so they are still having difficulties to this day.
