Selling him for 50M and getting Osimhen will be a wonderful business.
It's obviously a win win solution for MU and Napoli.
Napoli has decreased Osimhen's release clause to the 55 million, which even far below from last season. it's bargain price for United to buy him out from Napoli.
It dropped to 75-80 million range, not to 55 million, that would be too small and that is not realistic. Manchester United should definitely get him, there is no questions about it and that would be the best thing they have done in many years, they need him desperately and they should pay whatever they can to get him.
Garnacho for 50 million makes no sense to me, I still like Garnacho and he is young, but Hojlund seems like he is not good enough for United, so selling Hojlund plus Antony would make 50+ million give or take, and they could get Osimhen easily that way. Plus they would be keeping Garnacho in that case too. But if Garnacho insists on being sold, then Garnacho+Hojlund+Antony trio could cover the whole cost of Osimhen, including maybe some of salary too.
