I just hope they don't lose too many of the main players who contributed a lot last season, because that will make the framework of the team that has been formed will change, and it might have a negative impact on them.
Actually, there are advantages and disadvantages that Napoli can experience when making player loans.
The advantage is that Napoli can get some money and also have more experienced players for the future but the disadvantage that can be obtained is when a player suffers a fatal injury plus there can be a shortage of players who should be able to strengthen their own club.
But everything returns to Napoli's management because when they decide to lend a player, there are backup options in case something goes wrong.
When they decide to loan out their existing players, of course they have considered the worst possibilities that they will face, one of which is as you said, being hit by injuries and so on. But we also have to look at it as an option, I mean when the players are in the squad but they don't play, then I think that's not a good thing, especially for the future of the player himself, especially if the player has good potential. The management must also be wise in seeing the opportunities for players on loan, especially in choosing a club that will provide many playing opportunities.
Yes maybe it is a disadvantage and advantage in itself, but in that choice there is the best choice, so choose the best of all choices. Players will also be happy if they are loaned out to a club that is ready to give them the opportunity to play, because for young players having many minutes to play is certainly a good thing.
