Santos have announced they're prepared to sell Paulo Henrique Ganso this summer.
Santos president Luis Alvaro Ribeiro has challenged clubs to come up with the right price.
"Santos do not want unhappy players," he told Radio Globo. "If he wants to leave and a bid meets our valuation, he can leave.
"The player is eager to shine and that is something that is in both his interests and the club's. If he plays well, certainly better offers will come in the middle of the year."
