Santos are keen to re-sign Diego Ribas from Atletico Madrid.
Diego's father admits his son's former club wants to take him back to Brazil.
Djair Ribas told Globo Esporte: "The interest [between Santos and Diego] is mutual, there is a big chance of him returning to Brazil. Other Brazilian clubs are interested, but he prefers Santos.
"We will wait until the last games to talk, Diego is under contract with Atletico Madrid and a lot of things can happen."
Santos sports director Andre Zanotta added: "It's a difficult negotiation.
"Diego is shining at the moment in a club that is a big success this year. We talked with his father, but there is nothing certain yet.
"It's a dream, we would really live to bring Diego here, but can't say he is close. He is a player we are always interested, no matter who runs the club. The club's doors will always be open because of the success he had here."
