Watford have announced the signing of right-back Mario Gaspar on a free transfer.
The 31-year-old left Villarreal this summer after over a decade with the Spanish club, having risen through their youth ranks to make his senior debut in 2009.
He is Watford's fourth signing of the summer window, after capturing Vakoun Issouf Bayo for £5million as well as Ben Hamer and Rey Manaj on free deals.
Gaspar sits third in the the Yellow Submarine's all-time appearances list, having played over 400 games at the LaLiga club.
Although not part of an official swap deal, the former Spanish international replaces Kiko Femenia at right-back, who went in the other direction and joined Villarreal on a three-year deal after five years with the Hornets.
