Sunderland boss David Moyes is reportedly pursuing Swansea City defender Neil Taylor as the Scot seeks a replacement for Crystal Palace-bound Patrick Van Aanholt.
Van Aanholt is believed to be on the cusp of joining Palace in a £9m deal, leaving Sunderland short at left-back as the Black Cats battle to remain in the Premier League this season.
According to The Mirror, Sunderland have submitted a £3m offer for Taylor, whose place in the Swansea team is under threat following the arrival of Martin Olsson from Norwich City last week.
Taylor, who is currently recovering from a fractured cheekbone, has made 11 Premier League appearances for Swansea this season.
The 27-year-old has represented the Welsh outfit since a £150,000 move from Wrexham in 2010.
