Hornets youngster Alex Jakubiak has signed a youth loan at League Two side Oxford United until January 4.
The striker has made one first-team appearance for Watford which came on the final day of last season. The Golden Boys were beaten 4-1 at home by Huddersfield Town and the 17-year-old featured for 58 minutes.
It will be Jakubiak's second loan spell away from Vicarage Road. He spent just over two months at Conference side Braintee Town last season and made 11 appearances for the club, scoring once.
