In short, the team should also make sure to upgrade their techniques to get a hold of the changing environment. Sure, their old tactics were working before, but should assess its applicability in today's generation so as not to be left behind. Just like any other game or sports, everyone should also check the current performance of their team and how to be competitive with others. The old one is not the absolute path to be taken but they can always gain insights on how to proceed their succeeding plans.

Borrowing from the saying that you can't keep doing same thing and expect a different result... For now there seem to be no one with such a high level of technicalities and a different style of coaching away from the normal Italian style in Italy, so I agree with you on the idea of looking out for an outsider, maybe from Brazil, Spain, Germany or England, this might go a long way in helping the team improve on their game.
