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."
