Kvaratskhelia could be an option for Mbappe's replacement when he decides to leave this season but for Rodrygo it seems a little difficult.
He is still the center of attention in Madrid even if there will be Mbappe in Madrid but it will not interfere with Rodrygo in terms of position so there will indeed be no problem for this player and will remain in Madrid.

There will still be a hot topic of discussion regarding who will replace Mbappe later and what is clear is that PSG will immediately try to get their target player. Kvaratskhelia is considered very suitable for PSG's left winger position and of course Napoli will charge quite an expensive fee. On the other hand, this will be a difficult negotiation process.
Rodrygo will probably always want to play as a left winger and he can make that happen at PSG but I doubt he will consider PSG's offer if it ever comes along. Rodrygo is still very comfortable at Real Madrid and he always has the main position in Ancelotti's hands. So I don't think he will go to PSG.
