Juan Camilo Zuniga has joined Watford on a season-long loan deal from Napoli, the Premier League club have confirmed.
The attacking full-back arrives at Vicarage Road to reunite with head coach Walter Mazzarri, whom he played under at Napoli for four years.
The deal for Zuniga also includes an option for Watford to make the switch permanent at the end of the season.
Zuniga has become Watford’s fourth signing ahead of the new campaign after Jerome Sinclair, Christian Kabasele and Isaac Success all joined earlier this summer.
The 30-year-old played 163 times for Napoli and has 62 international caps for Colombia.
