Saracens centre Marcelo Bosch has extended his contract with the Premiership club.
Argentina international Bosch has made 40 appearances for the north London side since joining from French side Biarritz in October 2013.
"Ever since I arrived at the club, I have been treated extremely well," the 31-year-old said.
"Coming here was a big challenge for me. I'm still trying to learn and still trying to improve."
Bosch, who has won 33 caps for the Pumas, kicked the winning points as Saracens beat Racing Metro in the European Rugby Champions Cup earlier this month.
"Marcelo has made huge improvements in his game and is constantly looking to get better as a player," Sarries director of rugby Mark McCall said.
"He has rediscovered his love for the game. His hunger and determination to improve is second to none."
Saracens have not disclosed the length of Bosch's new deal at Allianz Park.
