The only fear i have for Napoli is in the summer, because i know the clubs that have money will come for their best players like Osimhen and Kvaratskhelia, if they sell them, then they may not be so strong by next season.
I hope Napoli don't do that because both are the main player who made this achievement. If Napoli sell them for money, I believe they can't do like this anymore on next session until they find a decent player. Maybe better for management to create a new contract and do a big deal to make them keep stay on Napoli because hard to find a successor in the middle of a player crisis because all experienced players are getting all and will need a time again to recruit the young players.
There is no way they are keeping those players, definitely not Osimhen, we are talking about a team that would be getting offers more than what it costs to run the team as a whole, with sale of just Osimehn, they can have the whole next year, and all the profits this year, come for free, they would be paying every single cost with just one player sale.
How could you say no to an offer like that, we are talking about as high as 100 million, but at worst something like 60 million is guaranteed at this point. That is not an offer Napoli can refuse, it's just too much, sell 3-4 more players and you cover literally 2 years worth of cost, whatever profit you make is just pure profit, can't say no to that.
