Hull City, Sunderland and Swansea City are chasing Celtic striker Georgios Samaras, according to a report.
The Greece striker, who previously played in the Premier League for Manchester City, is out of contract in the summer and has so far refused to sign a new deal at Celtic Park.
The Mirror claims that clubs in Spain and Turkey are monitoring the situation, but Samaras is reportedly keen on a return to England.
The Black Cats were linked with a move in January.
