Santos have told interested clubs that Paulo Henrique Ganso will only leave for his buyout clause.
Santos president Luis Alvaro de Oliveira Ribeiro has confirmed the club are ready to sell Ganso, but only for his buy-out clause of over £40million.
Arsenal and Tottenham are chasing the youngster.
"Bring the offers, but we won't accept anything less than his buy-out fee," Ribeiro told Globo Esporte.
"The player's will always has to come first. It's pointless to keep an unhappy player. I always respect the player's will. I did that regarding Wesley, Andre, Jonathan, but Santos' rights have to be respected, as per the contracts that were signed."
