Van Rensburg will be moving to Bayonne at the end of the season and will join the Sharks this week.
The big prop is yet to win a Springbok cap but is determined to use this opportunity to prove he can play at the highest level.
“I will never give up that dream, I got a small taste of it [to be a Bok] at the end of the year and I am working hard to get it – I want to pull that jersey over my head and say I’m a real Springbok. I don’t enjoy being called a Springbok and I am not really one. The blazer still hangs over the arm, I am not allowed to wear it – I really want to put it over my shoulders, so hopefully this is my opportunity.” Said Van Rensburg.
