I'd gladly sacrifice Gio, if it meant the acquisition of Suarez/Jovetic. Even if we didn't sacrifice one of them, then we should get Suarez/Jovetic, simply because of the huge leap in quality, and marketing potential it could lend us.
I'm also sure Conte can make any formation involving 2 or 3 of Vuci, Gio, and Suarez/JoJo work. It definitely beats having an underwhelming strike force, and also allows us to focus all our efforts on a quality cf next summer (Cavani/Higuain). Ideally, we'd get Cavani/Higuain/RVP this summer, and one of JoJo/Suarez next year. I firmly believe we will be unstoppable then.
Matri, Quag, Borriello, and Gio are all dispensable; the only one I'd keep regardless is Vucinic (unless someone offers us 25 Million for him). Selling Matri, Elia, Krasic, Melo, and some of the other deadwood will generate at least 40 Million Euros, and free up wages as well. Enough for a top striker? You do the math
