Watford youngster Filip Stuparevic scored the winning goal as Serbia Under 21s beat Bulgaria in a European Championship qualifier on Friday night.

The 19-year-old, who is currently on loan with Czech club FK Pribram, came off the bench in the second-half before scoring the winner in the 87th minute.

Stuparevic signed for Watford from Serbian club FK Vozdovac in January this year, before remaining in Belgrade on loan.

He holds the record as the youngest player to play in the Serbian SuperLiga, when he made his debut aged just 15.
