Napoli has lost Kvaratskhelia who left for PSG, so to replace him, Napoli actually want to recruit Garnacho at the moment but I think it is difficult for Manchester United to let him go this season, because after all they still need Garnacho very much in order to be able to improve their position and also their performance, currently Manchester United who are in bad shape in the league actually surprised us by performing very impressively in the UEL, even they can qualify automatically to the round of 16 by being the only team that unbeaten in UEL and this is inversely proportional to what we see in the EPL, I think, Manchester United needs to maintain and even add to their squad to be able to continue to compete and win the UEL this season, because currently the UEL is their only chance to win the prestigious trophy and play ticket to the UCL next season.
We're in the middle of the season, a period clubs in Europe will do everything to maximize the potentials of their players and at such, I don't expect Manchester United to let an important player like Alejandro Garnacho to leave the club at this time and join Napoli. Just like you said, they need the Argentine is a big asset for the Manchester club as they fight to win the UEFA Europa League competition this season.Marcus Rashford is the player that the manager have deemed surplus to requirements at the club and if there's any player that's more likely to leave, I think it'll be him. Manchester United are one of the favorites to win the UEL trophy this season and if Ruben Amorim can continue his impressive run in the competition, I think they might end up with the trophy
