A report claims that Wolves and QPR are among those to have watched Thomas, who has scored seven goals this season.
Hartlepool United winger Nathan Thomas is being tracked by a number of higher-division clubs, including Wolverhampton Wanderers and Queens Park Rangers, Sky Sports reports.
Thomas has scored seven goals for League Two Hartlepool this season – and 12 this calendar year – and signed a new, undisclosed contract in June.
It is claimed that Charlton Athletic are hoping to secure a £750,000 deal for Thomas when the transfer window reopens, but as many of four Championship clubs may have something to say about that.
As well as Wolves and QPR, Birmingham City and Wigan Athletic are both said to have watched the 21-year-old this season.
Wolves, however, are particularly strong in wide areas, with Ola John, Helder Costa, Ivan Cavaleiro and Jed Wallace all capable of playing there, along with injured duo Jordan Graham and Michal Zyro.
In contrast, QPR saw wingers Matt Phillips and Junior Hoilett depart during the summer transfer window, with new recruit Yeni N’Gbakoto missing for the best part of the last two months.
Once on Sunderland’s books, Thomas has also payed for Plymouth Argyle, Motherwell and Mansfield Town.
