That's what makes Xabi become one of the best young coaches in the world today. Because PSV has a style of play that suits what Xabi wants in his football philosophy. Even though he doesn't have any famous star players, or maybe I don't know him, Xabi was able to build strong chemistry between the players and in the end they were able to adopt the tactics and style of play that Xabi wanted.
I fully agree on that , that Xabi Alonso is one of if not the best young coaches today , and also on top on that he will be for sure get at some point to the bif teams.
He was already a very good player when he was playing and he is continue that now also as a coach.
There are Florian Wirtz , Granit Xhaka , Alejandro Grimaldo , Victor Boniface that are very very good players he have.
Not famous as others but maybe on that way to it.
