I am sure that Dinho won't be the same from last year if he stays in Milan. He was brilliant last year but for the first time in quite some time he looked motivated. With the WC behind us and after he failed to make it there, do you think that he will be just as motivated as he was last year?
It's true that one doesn't need a WC to be motivated, but in Dinho's case I think it played a huge role. That and Leonardo's capability to get the best out of him.
And lets be honest, last year's Milan without Ronaldinho wasn't any better than last year's Juve. They don't seem eager to invest in new players, they are trying to get rid of Dinho's wages and even if he stays I doubt he will try to do much.
They're everything but a scudetto or CL winning team material.
