i'am with the 4-2-3-1 formation the modern football is about playin' with wings.. play Marchisio as a CM and someone like Melo if not him as a DM and we don't need Aquilani and get some one like Pastore as an AMC an get Giovinco back or someone else if not him as a LW and 2 fullbacks then we are set.. it's about 3 or 4 classy players needed i can live with Quag or Matri as a CF if the 3 behind him are deadly and can score goals and secured with great fullbacks..
I agree, Marchisio would excel in a modern 3 central midfielder formation.
How many Home Grown players Juventus have? Don't think that many. Therefore Marchisio becomes no brainer to stay.
Sell Melo, replace him with someone else mentally tougher fighter. And forget about Aqua unless his transfer fee could be lowered to about same price as we could get from selling Sissoko, also Aqua's wage should be lowered as I see him as a squad player rather than starter.
Get a really creative player either ACM or CM: my choice would be Pastore or Montolivo (or even both if we let Aqua go)
They could work in formations like this:
--------- Quagliarella --------- ---------- Quagliarella -----------
LW -------------------- Krasic LW ----------------------- Krasic
--- Marchisio ---- Montolivo -- ------------ Pastore -------------
------------- DM ------------- ----- Marchisio ------ DM --------
