God....I hate it when threads are hijacked, and I had nothing to do with it.
Seedorf stays, because like maldini03 says, he's one of the best at what he does, and he can still win you matches single handedly. He was around a year before Kaka btw and he won us matches then.
He's one of those classy players whom you cannot get rid of. And let's not forget he has played as many matches as Kaka. Hard to say, why we go easy on Kaka who's 24 claiming fatigue, while a 32 year old is being plain lazy.
Sorry, I'm an old school, Seedorf+Andy P+Pippo fan.
But even if otherwise, we haven't got any bleeding creativity. Seedorf can play with R10, and with Kaka. And this is my favourite formation currently, we finally get that Milan which can start something without Pirlo.
------Flamini---Ambro-----
Kaka-------Clarence-----R20--
----------Pippo/<heck put Porty here>--
As for the rift in the dressing room, I doubt it. Because the other players get along with each other so well. And R20 doesn't strike me as the kind of player who poisons other people against each other
A dude who follows R20 (and I mean fanatically, posters in the room,T-shirts etc), says R20 was very hurt when Eto'o and co. turned on him like that in the Barca room. And he's unfortunately not the kind of guy who's good at dissing shite out as well as he receives it. So this party thing is his kind of shell. He isn't enjoying his football at Barca anymore, and he's looking to keep himself happy. Oh and I'm assured he's NOT arrogant. I'm told his elder brother is a prick though. R20 semi-worships de Assis, and most of the decision making is done by this guy. In fact this guy who is a staunch Barca fan, actually supports R20 coming to Milan. He feels it's the only place where R20 could get his head together again. What he told me was, R20 is not going through half the shite, that Ronaldo was going through, so if Milan could rehabilitate Ronaldo , Dinho should be a piece of cake.
I'm chatting with this dude right now on gtalk. So copy pasting almost.

In fact the only reservation I have about this transfer is the whole La Liga curse on Milan. Yet to see a La Liga player do well here.

If they can play, they get injured. If they don't get injured, they play like shite.
