The 29-year-old, whose current deal expires this summer, has now been offered a three-year contract at Santos, which his father and agent Djair says he is weighing up.
"The truth is that we are still talking about details of the contract but we haven't fixed a date to sign the contract," he told Globo Esporte.
"We are waiting for the Spanish league and the Champions League. But the numbers being offered are like what we want. They are within our expectations, it would be a three-year contract."
