It is still not a transfer that has happened but I think (if it happens) it would be a wrong transfer. PSG already has Barcola and Dembele, what would they do by buying Kvara?
These are players with the same characteristics and there are already 2 players with those characteristics in the team. Kvara is a young player, if PSG wants to polish him and sell him for a higher price like Mbappe after some time, then it can happen, but Napoli would not sell such a player cheaply anyway.
Why would Napoli ruin the chemistry of the team by selling a player while they are heading towards the championship? It is not a transfer that will happen in the mid-season transfer period, I think it will happen at the end of the year.
The transfer will happen sooner or later, because from the information gathered he has already reached an agreement with PSG and his salary will be 4 or 5 times his current salary at Napoli. PSG is not a team that can polish any player, they always buy ready made players for exorbitant fees, PSG and Manchester City are the reason why transfer market of today is like this, buying players with big money. Besides PSG didn't sell Mbappe for a penny, he Mbappe was a free agent and Real Madrid got him for free.
