I see you are really afraid about our B team, but I think that if Capello can trust on Tudor, Legro or even Montero to replace Cana and Thuram (lets remember that Cana and Thuram are not young players and that they need to rest, I like to have them at 100% to stop Adriano next November 28th) there won`t be any problem.
Lets remember that the "B" midfielders (Olivera, Kapo, Tachi and Appiah) have played some games and can afford this game.
About the strikers Zalayeta scored a year ago against Siena, and that Coppa game was his first game in the season, so now that he played more games I think he can score without problems, last year also Zala played with a youngster named Benjamin and this guy also scored so I think Capello can also take a youngster for this game.
I also noticed that you forgot Chimenti, remember that this guy did an excelent job last year so I don´t think Buffon will play this game.
Well maybe Capello will play with some 1st players but I hope he rest:
Cana or Thuram
