Daga was spotted at the Vicarage Road last weekend during Watford’s season-opening game against Queens Park Rangers.
Former Flying Eagles player Tom Dele-Bashiru scored one of Watford’s four goals in their 4-0 victory.
After putting on a masterful performance for the Flying Eagles at the 2023 FIFA U-20 World Cup in May, Daga has been linked with numerous teams in Europe.
The search for the defensive midfielder currently seems to be being led by Watford.
Daga, who will be 17 in January, must wait until he is 18 to sign a professional contract in Europe.
