Juve could do a simular thing.
What for that 30 mil we got nani
You could play 4231 with vidal and pirlo/marchisio holding the midfield, and depending on how much conte cares about tevez opinion a Tevez-oscar-Nani, or Oscar-Tevez-Nani, behind Llorente.
Its not ideal cause oscar is not as efficient on the wing and tevez is to slow and doesnt want to play there, but all the mercato after that needs, is one left winger.
I really, really think there's no way that'd work. Pirlo is a great player but has flaws, there's no way he'd be able to play with one guy next to him at this age. It could work with Marchisio (although I'd hate to see that).

Cuadrado is impossible. I have dreamed about this deal but you know that viola will rape us on the transferfee. And its possible Cerci alone would cost close to 20 mil.
Coentrao is a nice player, but not certainly he'd start over asamoah. Especially if we'd go 4-2-3-1 or even 4-3-3, conte would prefer the strongest of the two.
I think Di Maria is great, but he isnt as talented as Pogba. Oscar on the other hand could well be as talented or better then Pogba.
Money can get you anything. I know Viola would give us a hard time but I don't think it's impossible at all and one of the main reasons is because we have many talented kids that we could ship away to Fiorentina in order to land Caudrado.
If we do get an offensive + effective winger, like Di Maria, I'd most likely play Asamoah as a LB due to his defensive strength. It's a pity not to use him as a MC, though. I say Coentrao because we could use him and because I don't get the Morata obsession, I'd rather get Coentrao.
I rate Oscar just as much as you probably, but I think I have a Di Maria fetish

it's been way too long since I've seen a good winger at Juve, last were Nedved and Camo.
