Next season hopefully we´ll count on "signings" as Isla and Pepe. They'll give us good options as right wingers if Conte switches to a 433 in Europe.
As left wingers, we'd have Vucinic or Giovinco.
We'd need a cheap backup CB (like Diakite), a real LWB and Sanchez or Isco. Then we are completely set, with a whole lot of options in the squad, even turning to 433 or 4231 once in a while.
Giovinco would be a very decent option as a LW, way better than as a CF like nowadays.
