Borussia Dortmund paid Wolverhampton Wanderers €22.5 million for Silva last summer, but the investment has yielded little return: the 24-year-old has managed just three goals in 39 competitive appearances, used mostly as a substitute under Niko Kovac.
According to Bild, both Real Sociedad and Real Betis have registered their interest in offering the forward an escape route from a role that has left him increasingly frustrated.
Silva already has experience of LaLiga football, having spent the 2024-25 season on loan at UD Las Palmas before his move to Germany, where he scored ten goals and added three assists for the Canary Islands club.
That form was enough to persuade Dortmund to make their move, but he has struggled to force his way past Serhou Guirassy in Kovac's system since arriving at Signal Iduna Park, leaving him short of the regular football he enjoyed in Spain.
Despite the growing interest from Spain, Silva is understood to have signalled internally that he wants to fight for his place at Dortmund next season rather than push for an immediate exit.
The Portugal international, who has one senior cap to his name, remains under contract until 2030, giving Dortmund little financial pressure to sell. Even so, the German runners-up could be open to ending the arrangement early should a club match their valuation, particularly given how limited Silva's game time has been since his big-money arrival.
Both Spanish clubs see the forward as a squad reinforcement capable of adding energy and directness to their attack, with Real Sociedad reportedly viewing him as a potential partner for Mikel Oyarzabal and Betis regarding him as a natural fit for their own front line under Manuel Pellegrini.
Silva's route back to regular first-team football is likely to hinge on how quickly a suitable structure, whether loan or permanent, can be agreed between the interested clubs and a Dortmund hierarchy that remains reluctant to fully write off their outlay from just twelve months ago.
