i don't think that any strict italians only policy even exists now. they should speak italian, that's a given, and i think that's all. after conte left, sinisa was considered (agnelli was a fan), agnelli would have also hired guardiola if he was available, at one point zidane will coach juve, we already hired deschamps for the serie b season (and it was him who left, he wasn't even fired), and when allegri was about to be sacked, both tudor and motta were mentioned as potential successors.
