Villarreal president Fernando Roig says this summer could be the right time to sell Pau Torres.
The Spain defender has just helped Villarreal win the Europa League, with beaten opponents Manchester United keen on his signing.
Real Madrid, Barcelona and Napoli are also being mentioned as suitors.
"If they come with the money and the player wants to leave," Roig told El Transistor.
"But there must be an agreement between all three parties."
