Players unsuited to tactics
Josep Maria Bartomeu is involved in a power struggle and felt bringing Xavi to Camp Nou would buy him some time. The move backfired and he was left nothing to show for.
In a power move, Ernesto Valverde was removed despite his enjoying Lionel Messi’s confidence. New manager, Quique Setien was ushered in the middle of season to change their philosophy and deliver trophies. It simply does not work like this.
