eeeeek we are without Totti! he is broken still and isn't in the squad. Nor are Taddei, Aquilani or a few minor players, but Francè is the most serious absence. Even though he's rarely at his best against Lazio, I think he cares too much, we could do with his galvanising and totemic presence. That said, the last derby we won (Feb 2006, 0-2) was when he was out with his pre-Mondiali ankle injury. So he's not essential.
But Lazio aren't in a great place, lots of injuries, been struggling a little, currently 14th in the league equal on points with Milan.
Objectively, we ought to win. But I don't like making predictions, and especially not for the derby. Speriamo bene.
