They have no bargaining power with Pjaca. The other team interested in him is Fiorentina and I doubt they'll pay a lot. I can see Pjaca going on another Loand+option deal somewhere. At that point, I would be interested in him. I know this is probably not a popular opinion, but I still believe in Pjaca's talent and ability. I don't care that he chose Juventus over Milan 2 years ago. That ACL set him back a lot, but he is still one of the better dribblers and direct players around. People for example were wanting to spend big money on Pavon, but imo Pjaca is a much better direct player. He needs to stay healthy and needs to play. Again, no way would I except him in the Bonucci deal, but as a separate one where we likely get to loan him with an option to buy him.
I would make this deal to Juventus......
1. You buy Bonucci from us for 40M. (means we recognize a gain on the books for 6.4M)
2. We will immediately buy Caldara from you for 46.4 mil. (means that our gain + cash received washes out the Caldara fee and we are only out 6.4 mil cash, however it will all be reversed once we save about 6-7M from Bonucci's wages. At the same time, Juventus recognizes a big gain on Caldara and gets 6.4 mil cash. They probably don't care too much about the cash as much as they care about the gain)
3. Because we are valuing Caldara higher then Bonucci and that's really not the case in reality, however we are doing you a favor here by overvaluing Caldara....you will give us Pjaca on a Loan + Option to buy deal.
4. Higuain can be dealt with separately later on once we dump off Bacca and Kalinic.
Another thing to keep in mind is that it seems like Juventus are desparate to get rid of Higuain. Looks like they want to get him off their books, but no club out there is willing to meet their demand, hence why they are trying to package him up with Rugani to Chelsea or Caldara to Milan. I say screw them. We either take Caldara or we sell Bonucci to PSG/United (if rumors are true that they are interested).
Lastly, I would be eternally grateful to Leonardo if he manages to use his Brazilian magic and charm to somehow convince Douglas Costa and involve him in this deal!

I know, I know.....asking for too much as Juventus will never agree and they probably value him at 80+M..........BUT this is the beauty of the transfer market. We get to dream.
