Wigan Warriors winger Joe Burgess will join Australian National Rugby League side Sydney Roosters at the end of the 2015 Super League season.
General manager Kris Radlinski confirmed Burgess' exit at a fan forum.
"We did everything we could but he wants to experience the Sydney lifestyle," said Radlinski.
Burgess, 20, scored a try in Wigan's Grand Final defeat by St Helens and was selected in England's squad for the end-of-season Four Nations tournament.
Meanwhile, 19-year-old prop Ryan Sutton and 22-year-old half-back Sam Powell have agreed four-year contracts with the Warriors, who begin the new campaign with an away fixture at Widnes on 5 February.
