I think Inter will be deadly next year. Now they have something they haven't had for a very very long time, harmony in the team. On paper they have one of the best teams in the world, plus they will probably buy a big name or two in the summer.
I hope Milan holds onto their players, especially Kaká. They suffered enough from the loss of Sheva, this would break them. I hope they don't reinforce to much though, if they actually buy Ronaldinho there would be no stopping them.
Palermo and Roma will be indifferent, I believe. I'm not so sure about Lazio nor Fiorentina, can go either way.
