Watford have completed the signing of Filip Stuparevic.

According to his club in Serbia, FK Vozdovac, the deal is done for the 18-year-old to move to England.

But it is a transfer that will not be finalised until the summer, when the player arrives in England.

He will stay at his club until the end of the season on loan.

Stuparevic has the record for being the youngster player to ever play in the Serbian SuperLiga at 15!

The teenager told Vozdovac's website: "Everything happened very quickly, but I'm happy. I still remember the debut in Vozdovac as the youngest player and goals against the biggest rivals, staying at the club was a truly invaluable experience.

"I would like to express my gratitude to my family for support, as well as to the Football Club Vozdovac, which itself functions as one family."
