Serbian wonderkid Luka Adzic is being tracked by Sunderland.

The Sunderland Echo says the Black Cats sent scouts to watch the 18-year-old Crvena Zvevda youth prospect in the weekend Eternal Derby against bitterest rivals Partizan Belgrade.

But they face a battle to land the youngster, with the likes of Arsenal and Manchester City also keeping an eye on Adzic's progress.

A left winger, who can also play as a striker, Adzic is seen as one of the brightest lights in the Serbian game.

Adzic was an unused sub in the white hot encounter, as Red Star drew 1-1 with Partizan, maintaining their six point lead at the top of the division.
