Every team he goes [to], he makes every player better. I played under him and I was 32 and he made me better,” he added.”He was in Sassuolo, every player got better. Locatelli went to Juventus, Sensei went to Inter.”He is all details like everything has a reason. Whatever you do has a reason. He puts little squares on the field so you know you have the ball in the square, four squares is diagonal and there is going to be the number eight free and every player has six options to pass the ball, it is unbelievable,” he continued.
