Borriello, an aging zambrotta, a senseless tackling, headless chicken like Flamini, a washed up Ronaldinho, whose price-tag of 20 mil, if that, said it all ... those were cosmetic changes and not ones that implied Milan wanted the scudetto.
Ronaldinho was brought in only because of Silvio's weakness for him, evethough Ancelotti didn't want him and it's no surprise both Kaka and Carlo left the following season.
Milan's issues back then had more to do with an aging squad of quality but fed-up players, who had won it all, and were expected to compete well in both Serie A and CL at the same time, when they didn't really have the hunger for winning anymore - Reinforcements were needed, but not the ones mentioned above of average players or more fed-up, unmotivated stars, who'd rather dance it in the club till early hours.
Juve's issues at this point in time, are quite different ... still, with 100-120 mil this team can be banging in no time but my hope is in Marrotta pulling a Marotta once again and appointing another Italian coach with provincial mentality like Mazarri or mancini, and spending most of the money on the likes of Aquillani, Matri, Gilardino, etc.
