Paris - South Africa scrumhalf Cobus Reinach scored twice in front of his Test team-mates as Montpellier enjoyed a 32-21 win over Racing 92 in the French Top 14 on Saturday.
The Springboks are in France for the next week to avoid a Covid-19 quarantine in Britain before facing Wales on November 6.
The likes of Rugby World Cup winning captain Siya Kolisi and head coach Jacques Nienaber watched from the La Defense Arena stands as Reinach staked his claim for a starting berth next month with regular scrumhalf Faf de Klerk missing through injury.
Ons of his tries was described as a “worldie’ on social media after he ripped the ball from a Racing player and again showed his pace to score a long-range try.
"Cobus came back to bring his experience," Montpellier coach Philippe Saint-Andre said.
"He was also playing in front of his coach and he scores two tries," he added.
The Springboks also head to Scotland on November 13 before travelling to England a week later in a re-run of the 2019 World Cup final.
Reinach, 31, who will join up with the Boks before the trip to Cardiff, opened the scoring after five minutes, diving over from short range.
His club and international team-mate Handre Pollard started at centre for the first time since May 2018 and kicked a 55m penalty goal.

The former Northampton Saints half-back completed his double just before the interval with a superb 80m effort where he outsprinted Argentina winger Juan Imhoff after having ripped possession from Racing's No. 8 Yoan Tanga.
Pollard, who suffered a serious knee injury on the same pitch in September 2020, failed to repeat his first half exploit as he missed a long-range penalty with 10 minutes to play but Montpellier held on to move up to seventh in the table.
