European and Premiership champions Saracens have agreed a deal to sign Toulouse hooker Christopher Tolofua on a two-year contract from the start of next season.
The 22-year-old France international will link up with the London club next year following the conclusion of the 2016-17 Top 14 campaign.
Tolofua broke into the senior squad at Toulouse as a teenager and is looking forward to a new challenge at Sarries.
"I have spent a long time at Stade Toulousain, so joining another squad is a very big move for me and I know I could not find a better team than the Saracens." he said.
"I'm excited to play in England next season and test myself in the Aviva Premiership. I think it's the experience I need to take my rugby to the next stage, whilst serving my best for Sarries.
"The recent past of the Saracens speaks for itself and I am very proud to be joining such a good club with great coaches and great team-mates."
