Watford have signed Ecuador right-back Juan Carlos Paredes from Granada on a five-year contract.
The 27-year-old, who has 41 caps, played every minute of his country's World Cup campaign in Brazil as they finished third in Group E.
Granada, who, like Watford, are owned by the Italian Pozzo family, only signed Paredes from Ecuadorian side Sporting Barcelona earlier this summer.
The transfer is still subject to international clearance.
The terms for Paredes's move to Watford are undisclosed.
