Totti should be back for this one, I think, and probably Pizarro will start in midfield for Gago - he did very well vs Milan and helped Roma have a fluid, possession game in midfield. It's beyond me why LE keeps Pizarro out (unless he is injured but don't think so).
Boriello is also back from injury, but he will probably start from the bench.
De Rossi could appear at CB, although I'd expect Casseti to fill in that role ... unless Kjaer has a miraculous recovery.
