Swansea City are interested in signing Benfica and Argentina defender Lisandro Ezequiel Lopez to bolster their Premier League survival chances.
Lopez, 27, is wanted on loan by Swans boss Paul Clement, who has prioritised the recruitment of a central defender.
There is also a possibility that Wales international left-back Neil Taylor could leave Swansea before Tuesday evening's transfer window deadline.
Taylor, also 27, is a reported target for Championship club Aston Villa.
Lopez has struggled to secure a place in Benfica's side this season, having made only five league appearances, but could bolster a Swans defence which has conceded 51 Premier League goals this this term - the worst record in the top flight.
