Saracens will sign Biarritz Olympique centre Marcelo Bosch in October, the Times Series understands.

The versatile Argentinian, who can also play at fly-half and full-back, has agreed to move to the Men in Black but will not sign before the start of the season. 

We understand the 29-year-old will complete the switch after playing for the Pumas at the Four Nations Championship which starts on August 17 and ends October 5.

Bosch joined Biarritz in 2006 and has made 18 appearances for Argentina, scoring 21 points along the way.

Sarries chief executive Edward Griffiths said last month the club would not be making any additions before the new campaign, which starts on September 7.
