The 18-year-old has impressed for Crystal Palace and could be allowed to leave Selhurst Park after the club fell into administration.
Sunderland boss Steve Bruce is reportedly ready to make a £1million bid for Clyne.
A Selhurst Park insider told The Sunday Mirror: “It’s pretty obvious a lot of players will be sold as there are a lot of talented youngsters at the club.
“Nathaniel is a really good lad and a talented player and there is a lot of interest in him. It’s likely he will leave before the end of the window.”
