Watford will reportedly make Miguel Britos their eighth signing of the summer.
The 30-year-old currently plays for Napoli, but will join Watford from Udinese when the latter seal a move for the defender, according to the Watford Observer.
The possible instant switch to England is possible because both Udinese and Watford are owned by the Pozzo family.
Britos, a Uruguayan international, joined Napoli from Bologna four years ago.
