West Brom hope to raise £6 million from selling Villarreal and Sevilla target Borja Valero.
Albion paid a club-record £4.7million to Real Mallorca in August 2008 for Valero, 25, who failed to score in the Premier League last term as the Baggies were relegated.
The Hawthorns outfit then loaned midfielder Valero back to his former club in La Liga this season where he has starred again.
And that has alerted several bigger Spanish clubs to his availability this summer despite Albion returning to the top-flight.
