Saracens have signed England and British & Irish Lions back Elliot Daly from Premiership rivals Wasps in a deal to run from the 2019-20 season.
After announcing that he was leaving Wasps on Monday, Daly, 26, has now agreed a three-year deal with Sarries.
"I believe it is the right time in my career to explore a fresh challenge," said Daly, who can play at centre, winger or full-back.
"The opportunity to do that with Saracens really excites me," he added.
"It's a fantastic club who have had a lot of success in recent seasons. That's something that I want to be a part of."
Daly, who scored from full-back for England in Saturday's Six Nations win against Ireland in Dublin, had triggered a clause in his deal with Wasps allowing him to depart the Ricoh Arena this summer.
The Croydon-born back has scored 404 points in 188 appearances for Wasps since coming through the club's academy and making his senior debut in 2010.
Daly made his international bow against Ireland in 2016 and has scored 11 tries in 26 outings for England.
He will link up with several England team-mates at Sarries, who also have Owen Farrell, hooker Jamie George, locks George Kruis and Maro Itoje and the Vunipola brothers.
