Nani, Berardi and Cerci it is.
I'm aganist bringing Berardi back. Why would we bring him back if we don't clearly know whether Conte really wants the change of formations? In my opinion, even though I would much rather see a game play involving wingers, I don't see how Conte could possibly drop any of our current players besides Bonucci. Also Asa has excelled in the lwb position this season and while I don't know how he'd as a lb, I think he would be replaced with a true lb, if we did indeed get one. Another thing is Conte is a fan of a 2 man attack and Tevez and Llorente have been in very good form so I don't see how you would drop either one.
If we did transition to a 4-3-3, you'd have to answer these questions:
-Would conte drop Asa or play him at lb?
-Would conte drop tevez or play him as a winger?
-What player could we purchase in the summer mercato that could possibly upgrade our current 11? (That would fit our budget)
-Would Conte really drop Bonucci even after he hasn't dropped him after all of the fuck ups?
-Why would we change a winning formation?
