Real Madrid midfielder Casemiro is full of praise for PSG striker Kylian Mbappe.
Real president Florentino Perez is said to be pursuing the deal although PSG will be desperate to keep hold of the World Cup winner, who Casemiro rates highly.
"He is a great player," he said of the former Monaco man.
"Here [at Real Madrid], many players are spoken about. If Real Madrid signed everyone that they were linked with, we would have 100 players.
"Now he is a PSG player and I wish him good luck."
