Why nobody likes the Can - Paredes swap? IMO it makes a lot of sense because we give away a useless player who doesn't suit Sarri's game one bit and we get a decent Pjanic sub. He's a very good profile for Sarri's regista, should give some much needed breath to Pjanic.
Bentancur looks like a B2B and he'd stay there. Basically we improve our midfield while paying nothing and giving away a player we don't need in the process.
And then one could think of that 19yo attacker, should be enough money in the budget to do both operations in January.
