Newcastle United and West Brom are chasing Swindon striker Simon Cox.
Toon coach Colin Calderwood and Baggies assistant boss Mark Venus watched Cox bag his third hat-trick of the season during Swindon's 4-3 victory at Northampton on Tuesday.
Swindon boss Danny Wilson said: "I can see players in the Premier League at this time who have had a good career at that level but are not as good as Simon.
"There is no reason why Simon cannot step up. But it will take one hell of an offer to attract us."
