you couldn't help starting yet another thread, could you?
Dida seems to be out for at least for a month, so Kalac is it for the next several games - now I am sure everyone appreciates the value of early CL qualification
Simic is also injured, that's why he didn't play vs AEK. Billy left at HT for the exact same reason - injury. Doubt if any of these two would be ready for Messina. Kaladze is also out for sure, Marek is slightly injured but will most probably be ready to play.
I think there is a chance that Nesta and Cafu could be back as their injuries were not that serious. If so, I am guessing the backline would be something like:
Cafu/Bonera - Nesta/Bonera - Maldini - Bonera/Janku
If none of them is coming back, then probbaly Bonera takes the CB, Brocchi will drop at RB and Gorky or Ambro will take his place in midfield.
Ambrosini could be back too - most probably on the bench - as there was even a chance that he might play vs AEK.
Other than that, in midfield and attack, it's gonna be the usual suspects, I think.
