It's not only Brescia. We rarely convinced this season. That was often enough covered by free kicks or long range shots that gave us the win.
I have faith in facts
Honestly, I think you are far to optimistic. Let's look at the case.
We lost:
Zambrotta
Thuram
Cannavaro
Ibra
Vieira
Emerson
Mutu
Only Mutu cannot be called a starting player. That means we need to buy two top midfielders, two top central defenders, one top striker and one top full-back to cover the losses in the starting eleven. That's not going to happen. I think we need at least one top midfielder, a top and a good central defender and a good striker (for example Pizarro) to finish within the top 4. Don't underestimate teams like Fiorentina or Roma. It will be tough to be better than them next season.
I'm not talking about relegation. We are Juventus not Ascoli

I just think that we won't be back to normal within our first season in SerieA.
