Calling Deschamps an idiot is uncalled for, especially when leading a team to 5-0. Paro had to go in for an injured Zanetti. Marchionni, based on quality, deserves more playing minutes than Bojinov. Boumsong just came back from an injury and dd allows him a few minutes. Deschamps is also trying to give Trezeguet more confidence by keeping him on. Maybe it would've been slightly better letting Bojinov get those minutes, but I think what DD did is all reasonable.
Frankly, calling Deschamps an idiot now says more about the one mental state of the one calling dd an idiot than it does about Deschamps'.
