Rule 1 of coaching in Italy.
Must have a Regista in your team
we played a cl final with a double pivot
neither arthur or loca is a regista
you still need a good passer who can comfortably sit in front of defense though, and most teams have at least one player like that. kroos, modric, jorginho, kovacic, busquets, pedri, kimmich, tonali, verratti, brozovic, fabinho, list is way too long really. only a very few of them are actual registi.
