I thought the whole team played well. My ratings:
Abbiati: 6.5 He didnt have much to do at all, Cagliari's shots were all wayward but there were 2 vital saves he made.
Zambrotta: 6.5 He was solid
Thuram: 6.5 To be honest I dont think he saw much of the ball.. but did whatever it was that is necessary
Cannavaro: 7 He was solid, and made Cagliari worry with his two headers from corner kicks
Chiellini: 6 Still has room for improvement, but I think he is improving
Mutu: 7 I thought he played well, some nice dribbling as well, and helped the second goal
Giannichedda: 6 I dont think he needed to do much
Vieira: 7 What a relief to see him play like this from that horrible performance vs Fiorentina. Nice set up for the first goal, and he won most balls in midfield. Strong performance
Nedved: 7.5 Hes my MoTM. I thought he played extremely well. Very hardworking in midfield, and helped the defence as well. Was unselfish for the third goal, nice finishing for the first one. Brilliant.
Trezeguet: 7 I think Trez is more involved in this game than his usual standards

Should've gotten a hattrick, the fourth goal was very unlucky for him. Always well positioned, and made some nice passes throughout the game to open a window of goalscoring opportunity
Zlatan: 6.5 Not his best game and probably could've done better, but he still did reasonably well
