England international back Elliot Daly is set to join Saracens from Gallagher Premiership rivals Wasps in the summer.
Daly, who can play at full-back, wing or centre and also represented the British and Irish Lions, has signed a deal at Allianz Park until 2022.
"At 26, I believe it is the right time in my career to explore a fresh challenge and the opportunity to do that with Saracens really excites me," Daly said on the Saracens website.
"It's a fantastic club which has had a lot of success in recent seasons and that's something that I want to be a part of.
"I've played with a few of the lads for England and the Lions, as well as enjoyed battles against them in the Premiership, and I'm looking forward to calling them club team-mates from next season."
Croydon-born Daly played junior rugby at Beckenham and Dorking before joining Wasps' academy, making a first-team debut in 2010 and is a former Premiership Young Player of the Season.
Daly, twice nominated for European Player of the Year, has gone on to become a regular in Eddie Jones' England squad, scoring a try in the opening Guinness Six Nations win over Ireland in Dublin.
Saracens director of rugby Mark McCall feels Daly can make a major impact at Allianz Park.
"We are looking forward to welcoming Elliot to the club next season," McCall said.
"He's a talented player and at 26, his best years are ahead of him.
"Everyone at Saracens is excited to see him fulfil his potential with us."
