Maybe he can, and that's what the delay is? I have no idea. We know about his clause, with a deadline. But no one had said anything about after the deadline. If the clause is removed, then what happens?
DeLaurentis: His clause is 8M
Us: He's going to just resign next week and you get nothing. I'd look at getting a replacement in, if I were you.
ADL: If you fuck us like that, we're going to inflate the price of anyone you want to buy
Us: You already do that
ADL: Right. Well, it's about to get worse and we'll sell players like Jorginho to your rivals for less than what the current market is really saying
Us: Isn't that already happening?
ADL: Maybe we can work something out...
The details of the post deadline termination seem sketchy.
