I've already responded to that elsewhere - high wages and poor clubs.
It's quite clear that we'll need another left back to get the most out of a 4-3-3 formation, but we do have current options. If you play a strongly attacking/weak defensively play out left (Giovinco for example) then we could field Caceres at left back, as he does for Uruguay. Or Ogbonna. Worst case scenario, Chiellini. But it's really only going to call for one player, with Caceres as back up.
As I've said a dozen times, if we don't buy a left back it's because we aren't chasing one, so you will see us stay with mostly 3-5-2 and the Caceres option. Asamoah is one of the most important reasons for this, as well as Marchisio and our stacked CM.
The "high wages and poor clubs" excuse stands the same this year again, so what makes you think that this year MArotta will start making miracles and sell them all?
All these options were tried and failed, thats why conte has never used them again and thats why he can use a 4man d-line.
This is what the man has been asking ever since he has joined.
And i also said a dozen times, that Marotta just cant get a Juve material starter LB, he just cant, every year there were rumors and efforts and Marotta has been failing each and every year.
With your logic, were never interested on a finisher of Dzeko's, RVP, Cavani's and Higuain class either.
Its not htat MArotta can get what he wants, he is very limited, incompetent and always forced to compromise.
His best transfers were opportunity targets, most of the times he simply has waited for the player's contract to expire and wait for them to be attracted by Juve's fainting prestige...
