Udinese have sent Gabriele Angella, Fernando Forestieri and Neuton to sister club Watford on season long loan deals.
Giampaolo Pozzo, who already owns the Zebrette and La Liga side Granada, bought over the English Championship outfit in June. He installed Gianfranco Zola as manager and has since replenished the Hornets squad with fringe players from Udinese and Granada.
Almen Abdi, Matej Vydra and Alexandre Geijo have already made the move from Stadio Friuli to Vicarage Road, and now they will be joined by Italian full-back Angella, Argentine winger Forestieri and Brazilian centre-back Neuton.
The move brings the number of players on loan at Watford from either Granada or Udinese into double figures.
Abdi and Vydra both scored on their debuts as Zola's side came from behind to beat Crystal Palace 3-2 last Saturday.
