Watford have signed Spanish winger Albert Riera on a short-term deal until the end of the season subject to international clearance.

The former Manchester City and Liverpool player was released by Galatasaray in January and will enjoy a spell at Vicarage Road before joining Serie A side Udinese in the summer.

Meanwhile, long-serving defender Lloyd Doyley has penned a new one-year contract that will tie him to the club until the end of the 2014/15 season.

The 31-year-old has made 23 appearances this term and a total of 432 since making his Hornets debut in 2001.
