I don't want to sound over-confident but the biggest threat to us winning the scudetto again comes from Juventus itself. As long as the desire is there, we should win it again.
In fact, I think our B team could even win it: Neto, Lichsteiner, Benatia, Rugani, Evra, Sturaro, Lemina, Asamoah, Cuadrado? (if finalized), Mandzukic, Pjaca
Juventus C (Sassuolo) may be in with a shot of a top 4 finish as well.
