But PSG isn't right position to make Mbappe more valuable due his contract left one year, its difficult for PSG push up Mbappe's values because not any one teams interested for signing Mbappe and most of teams waiting until his contract over and sign him as free agent than have to spent much money. Indeed Real Madrid as teams rumor close to sign Mbappe but until right now not bid official proposal for signing him, I think Madrid tries waiting until PSG announce with official transfer offer.
For qualities, no one doubt with Mbappe but difficult sign him due expensive transfer fees from PSG and the interested teams faced difficult have to pay more expensive salary for him.
Until now, the future drama of Kylian Mbappe is still ongoing. Mbappe has a desire to play with PSG until his contract expires in the 2023-2024 season, while PSG wants to release Mbappe immediately after the new agreement is not well established.
Real Madrid who have shown their interest in Mbappe, can benefit from the situation between Mbappe and PSG. The attitude of not rushing and not wanting to pay dearly for Mbappe who was appointed by Real Madrid indicates that they only want to recruit Mbappe in 2024 on a free transfer, these conditions clearly make PSG suffer a loss if Mbappe leaves for free.
PSG must provide a transfer discount to a club that wants to bring in Mbappe, this method needs to be taken by PSG to get some money instead of letting the player just leave.
