British and Irish Lions centre Jamie Roberts has completed his deal to join Harlequins next season.
The 28-year-old Wales player will join the Twickenham Stoop outfit this summer after two years in Paris with Top 14 giants Racing Metro.
Harlequins boss Conor O'Shea tipped former Cardiff Blues star Roberts to become "a massive contributor to the history of this club".
Roberts will link up with Harlequins after Wales' World Cup exploits in the autumn and is likely to be available for selection from December.

"The whole club is ecstatic to have signed a player of Jamie's quality," said Harlequins rugby director O'Shea.
"He is massively ambitious to achieve at both club and international level.
"As a role model to all of our players, he will be someone we can all learn from.
"We know we won't see Jamie in the Harlequins jersey for a while yet, but when we do I know he will be a massive contributor to the history of this club, the development of our team and the development of young players."
