Frank Onyeka wants to leave Brentford but needs to be allowed to leave on loan to pursue interest from clubs like Valencia in Spain before transfer deadline day.
The Nigeria international, 26, is currently only allowed to leave on a permanent deal but is seeking more game time away from west London.
Valencia, Valladolid and Las Palmas have all registered serious interest for Onyeka - who was a late substitute in both of the club’s matches against Crystal Palace and Liverpool this season.
But the three Spanish clubs can only afford to sign him on a season-long loan, with help needed to pay a portion of his wages.
Italian club Lecce and Russian giants CSKA Moscow have also previously registered loan bids in the last few months.
Onyeka's primary motivation to leave Brentford is to become a regular starter after over a year on the bench under manager Thomas Frank.
