Skysports.com understands Sunderland are lining up a move for Blackpool midfielder David Vaughan.
Vaughan is out of contract in the summer at Bloomfield Road and he has yet to agree a new deal with the Seasiders.
Blackpool are now facing a major battle to keep hold of the Wales international with the player likely to move on if they suffer relegation back to the Championship.
A number of clubs at home and abroad are thought to be waiting in the wings to sign Vaughan on a free transfer following his fine showings this season.
The 28-year-old, who has been one of Blackpool's star performers this season, has previously admitted he would keep his options open this summer.
Sunderland boss Steve Bruce is thought to be a big admirer of the hard-working midfielder and is keen to lure him to the Stadium of Light.
Bruce has made midfield reinforcements one of his top priorities this summer and he is ready to offer Vaughan a lucrative deal in a bid to win the race for his services.
