Spanish club Real Zaragoza have been given permission to talk to Sunderland defender Paulo da Silva.
The 30-year-old Paraguay international is understood to havetravelled to Spain to discuss a move after struggling to force his wayinto Steve Bruce's plans on Wearside.
Da Silva, who has also attracted interest from Mexican side CruzAzul, has made only one Barclays Premier League appearance this season,starting the 1-0 defeat at West Brom on August 21.
He arrived in England from another Mexican club, Toluca, in July 2009 and made 21 appearances in his first season.
Manager Steve Bruce admitted that he had probably thrown the playerin too early on the basis of his experience working with South Americanimports in the past.
But with the club having invested heavily in the likes of MichaelTurner and Titus Bramble, as well as loan signing Nedum Onuoha, hischances have been limited.
Da Silva was a key figure in Paraguay's march to the World Cupquarter-finals in South Africa last summer, but it has been clear forsome time that his future lies away from the Stadium of Light.
Meanwhile, the Black Cats were today edging forward in the bid too bring both Stephane Sessegnon and Sulley Muntari to the club.
Negotiations are ongoing in both cases with the Sessegnon deal understood to be further advanced and, although there is still work to be done, Sunderland remain hopeful of landing both men ahead of Monday's transfer deadline.
