Inter lost a lot at the coaching department. But this will only will be proved in europe. The quality gap between them and the rest of the serie A teams is that great, it wont affect them, the new players and coach will give them the ambition to keep winning it.
Roma is a loser team with a loser coach, they will do what they do best, rank second. Berlu needs to sell Milan.
As for poor Juve we might recover Neddy's loss with Krasic this year, but we have such a limited coach, he will try to adapt the team to his views, this process will need time, maybe several season. But we lack the patience to wait and we need results now, thus sacrificing our long term plans, in a futile effort to do just a bit better now. With other words, we are the new Inter, bar the available funds and we prefer Italian, where they prefered international talents.
Benitez will do great in Italy, because defense is valued here and the pieces are already set for him to dominate the years to come. Moratti has finally found the man he wanted to lead his team to victories for the next decade, whilst, the old powers, Juve+Milan are still crippled.
The league as a whole loses prestige, as there is only one great team, by EU standards, but it becomes more compact, as the small teams grow stronger (doria, napoli, palermo) and former glories fade...
