Just be patience. Napoli is working on it, and they have almost reached agreement with MU for Hojlund's transfer. I've heard they will get him with obligation to buy worth 45m pound. That amounts sounds better caused by MU bought him for 72m pound. That's 27m pound realized loss suffer by MU.
Time is ticking, and Hojlund will come to the naples asap.
But now, letting Hojlund go is clearly a good option, because even if forced into the Premier League, Hojlund's performance has clearly declined, and it would be better for him to return to Serie A.Furthermore, I think Napoli also wants this player, especially since they still have the return from the Osimhen transfer, so this price is still quite reasonable, especially since we know Lukaku can't be forced to join them this season.
The transfer window is entering its final phase, and I think this will be completed soon. It would be pointless to continue pushing negotiations with time running out, as this would only result in losses for both clubs. Manchester United would lose more money, and Napoli would certainly lose one of their attacking forces, which could affect their performance.
