Sunderland are reportedly prepared to launch an offer for Crystal Palace youngster Wilfried Zaha.

The 19-year-old winger was hot property during the January transfer window, with Manchester United and Liverpool believed to be monitoring the player.

It is understood that the Black Cats will try to fend off any rival bidders for the teenager by lodging an offer this summer, according to the Northern Echo.

While the Championship side rejected an approach from Bolton Wanderers earlier this year, it is thought that the club will let Zaha leave Selhurst Park if they receive a bid of around £4m.
