I don't mind having DV. It will take some time for him to adjust to the new team. Remember how long it took Nedved, and even ZZ to settle in. I still think he's doing better than the other newcomers esp. Baiocco. Give him some time, and he'll be good again.
As for the Lazio game, i'm quite confident we'll get all three points. This seems the opposite of last year when we struggled vs big teams. I'm more worried about our performances vs the likes of Como, Brescia, and some of the smaller teams.
