On-loan at Valencia, the Portugal striker could sign for Los Che for €40m at the end of this season.
Pundit Frederic Hermel told RMC: "I would like to say to Mr. (Antero) Henrique: 'Do not sell Gonçalo Guedes at the end of the season!'.
"The Portuguese is loaned with no option to buy for the club Valencia in Spain and see the place he is taking in this team and in the Spanish league, he is a player who will be worth a lot of money in the month of June.
"With the stories of Financial Fair Play, PSG needs to sell, it can make a nice added value on this player, beyond the €40 million proposed by Valencia. Nothing is done yet. He has become an essential starter of this team which is having a very good season. Guedes is going to have a staggering price on the transfer market, which could tempt PSG to sell him and get some money back, but I think that would be a mistake.
"Because he has something special that big clubs need and which, I feel, PSG needs."
