If we plan to play 4-3-3 then I can't see buying Vucinic and Rossi without selling Quagliarella.
Vucinic-Rossi-Krasic could be the staring trio, with Del Piero (where will he play in 4-3-3 though?), Matri and Pepe/Martinez as their subs. There is really no place for both Matri and Quag on the bench.
Or maybe buy Vucinic, not buy Rossi, keep Quag, play 4-3-3 and buy the champion for the midfield (the third man next to Pirlo and Vidal), but who would that guy be? We're not linked to any top midfielder and it's pretty clear from our actions that we're looking for the champion in attack.
I fear that it's a 4-4-2 we're gonna play and Conte is looking for Vucinic as a winger. That is why Vucinic doesn't exclude the champ in attack and that is why we're not seriously pushing for Bastos, Vargas or whoever that could play on the wing. I'd like to think it would be a genius move by Conte, but everything tells me that it's gonna be a disastrous experiment.
