England fly-half Owen Farrell has agreed a new "long-term" deal to remain at Saracens, the Premiership club confirmed on Tuesday.
The 23-year-old came through the ranks at the Allianz Park club and has gone on to make 109 appearances since making his debut in 2008.
"I'm chuffed," said Farrell. "I've loved every minute that I've had at Saracens and, how we've been going over the last few years, hopefully we can continue to get better and better.
"I owe a lot to this club, in terms of how I've improved as a player and how I've done in my career. Hopefully I've given as much to the club in return.
"I'm delighted that I've been able to extend my deal here and I'm really looking forward to rip into the rest of the season and the years ahead."
Farrell returned from a three-month lay-off to come off the bench during the second half of Saturday's European Rugby Champions Cup semi-final defeat to Clermont Auvergne.
Director of rugby Mark McCall added: "Owen is one of the leading players in Europe, if not the world, so for him to commit his long-term future to the club is fantastic news.
"He is another player who has progressed through the ranks at Saracens to become a key player for club and country.
"He is a Saracen through and through and his hunger and drive to keep on improving is exceptional. The whole club is looking forward to seeing him at Allianz Park over the coming years."
