Honestly, in terms of quality, I think Boumsong and Kovac are good enough players, especially in Serie B. I think they just need time to gel and get some chemistry. It's going to be hard for them coming from the kind of cover that we're used to, we're used to having the best defenders in the planet during their time. Look at Iuliano and Montero, they were the best of their times. After that was Thuram and Cannavaro, also the best of their time. It would be hard to compare that with what we have now, but we're in Serie B now and Kovac and Boom-boom should be fine.
I still think our team is championship calibre for Serie B, although I'd be a little worried what would happen to us when we get back to Serie A. We need to have more quality signings over the next months if we're anticipating a return to Serie A. Otherwise, the summer period would be insufficient to build from scratch the team we need to compete again at the highest level.
