more importantly man u built its model(even financial) on footballistic success, and nobody has an idea of that more than the coach himself, and that is another reason, like you pointed out, why man u was so successful their coach was also their manager, so he knew exactly what would make his team better and how far they could get. but allegri is not the one doing the restructuring, thats the reason why hes here in the first place. It;s on marotta and agnelli so far, and i wouldnt trust them on a footballistic level.
