London Broncos have signed half-back William Barthau from Catalans Dragons on a two-year deal.
The 24-year-old, who made 16 appearances for the Dragons, will link up with the relegated Super League club from the start of 2015.
"The challenge is to get into the top four and then play four Super League clubs to show we are ready to play in Super League again," Barthau is quoted as saying by BBC Sport. "I know that I can play my part in helping the club achieve this."
Barthau has won eight international caps for France.
