Valencia coach Marcelino cannot guarantee keeping hold of Goncalo Guedes.
On-loan from PSG, Guedes has been outstanding for Valencia this season - and Los Che hope to sign him outright.
However, Marcelino conceded: "Guedes? It depends on PSG, who has the rights and who decides what he wants to do with the player.
"Then we'll see if Valencia can have him for the next season."
For his part, Guedes' father has declared in recent weeks that his son would like to continue with Valencia next season.
