i bolded out their most known players from that squad. you can see that Inzaghi and Gattuso barely even played, Zambrotta a little more than them but still too insignificant. Seedorf, Ambrosini, Nesta all less than 1500 minutes (which is how much Rugani or Morata played for us last season for example, in the league only). Ibra, Silva and van Bommel were the only "stars" with 2000+ minutes and you got players like Nocerino, Abate, Robinho, Bonera or Antonini getting key minutes that season. seriously, if it wasnt for Ibra and Silva, im not even sure Milan would have qualified for CL that season
