I wouldn't bother with Kovacic.
If we do indeed sell Asomoah and Pereyra, they nearly funds Pjanic. We can still spend a lot more. I wouldn't settle for Pjanic only. He really is better as a regista. They should buy a trequartista as well.
My perfect mercato would see us evalulate all of the following:
-ship off players a number of none-core players or players with inflated prices: Padoin, Neto, Asamoah, Zaza, Pereyra, Caceres, Lichtsteiner (if Chelsea is willing to pay 15-20 million), Hernanes to China (he is a good depth option, but for the right fee, I'd sell), Sturaro (once again if fee is staggering, but I'd lean to keep him)
-Complete the rumoured deals: Alves, Pjanic, Berardi (although I am skeptical on how he fits in, can he play central striker?)
These are great signings
-Let Real take Morata back:
Not that I want him to leave, but the opportunity cost is too high.
-Sign a few cheap, depth, Italian options: De Sciglio/Darmian, Graziano Pelle (cheap, and effective), Mirante, Marrone, Ciro Immobile (home grown), Mattia Destro (thought of as high potential, and had an insane strike rate with Roma a couple of years ago)
Some of these names look ordinary, but these players are primarily depth, and some are homegrown.
-Retain: Cuadrado (use Asamoah/Licht deals as leverage)
- Make 1 big purchase to boost Juventus brand: James Rodriguez is the obvious candidate (alternatives are not nearly as marketable), while another is Lorenzo Insigne (who's agent made a comment on having other options today). Other options include Gotze, Isco, although I feel like he is a tad overrated.
-Consider Ibrahimovic on a free if he is willing to take a material paycut to win a UCL. Ibra has his problems but he would undoubtedly make us a lot more dangerous. I would not overpay him though.
Obviously you don't do all of these options - I do think the most important is adding a bonafide creative trequartista, followed by filling depth with Italian talent. Depth players from other countries are not necessary: Fill your depth domestically...
