Bolton Wanderers, Blackburn and Middlesbrough have all been alerted to Hedwiges Maduro's availability at Valencia.
There is no place for the Dutchman in new coach Unai Emery's plans at Valencia and his name has been circulated to clubs across Spain and in the Premiership.
Blackburn are aware of Maduro's availability after holding talks with Valencia last week over Joaquin and Nikola Zigic.
