Southampton midfielder Jack Cork has reportedly been made a January transfer target of four Premier League clubs.
The 25-year-old has featured on 10 occasions for the Saints in all competitions this season and has scored three goals.
However, his contract is due to expire in the summer and as yet, no agreement has been reached over an extension.
That has alerted West Ham United, Swansea City, Sunderland and Crystal Palace, all of whom are considering making a bid for his services in the winter window, according to The People.
Cork joined Southampton from Chelsea for £750,000 back in 2011.
