Watford manager Walter Mazzarri has added two more fresh faces to his squad after signing Sunderland defender Younes Kaboul and Juventus attacking midfielder Roberto Pereyra.
Kaboul, 30, joins the Vicarage Road outfit on a three-year contract, while the 25-year-old Pereyra has been drafted in on a five-year deal, subject to a work permit.
Pereyra links up with Mazzarri at Watford after making just 13 appearances for Juve last season, having joined the Old Lady in a £12m permanent move following a successful loan spell in the 2014/15 campaign.
Kaboul, meanwhile, departs the Black Cats after just one season at the Stadium of Light, following a £3m move from Tottenham Hotspur.
Speaking to the club's official website after completing his move to the Hornets, Kaboul said: "I'm very happy and delighted to be a part of Watford Football Club, and I'm looking forward to the season.
"Just from outside, I can see it's a family club, there are some good players here and I'm very confident.
"The club had a very good season last year, and we need to carry that on to be even better."
