Corinthians are chasing Valencia midfielder Edu.
The former Arsenal star's agent has already held talks with Corinthians officials this week about a return home.
Corinthians president Andres Sanchis said: "He is a great player, who had a very beautiful story at Corinthians. Valencia are now delaying his wages.
"Edu is a player who interests us. But there's been nothing more than an informal conversation. We will see in the coming days."
