i think the club keeping his option open till now we are set for the 4 men defense line and three mids infront of it, but for the rest for its depend on the market and whats our options.
if we get lavezzi for example we can play 433 or4321, if we get someone like pastore we can play 4312 this is how i feel cuz if they already choose the formation like 4312 why we are after lavezzi?!
