Cape Town - The Springboks may have a disastrous record under French referee Jerome Garces, but flank Francois Louw says that is not cause for concern heading into Sunday's Rugby World Cup quarter-final against Wales in Yokohama. 

The Boks have won just four of their 14 Tests under Garces - a win percentage of just 29%.

The 34-year-old Louw, however, insists that the Boks have their heads in the right place when it comes to the officiating on Sunday. 

"We focus on our game," he told media on Wednesday.

"Our captain and various other players on the field will have a line of communication with the referee, and if there is anything of concern to us, we will try to relay that through the right channels to him, to sort that out.

"I don’t think anyone ever goes out – player or referee or match official – to purposefully make errors.

"But it is a high-intensity game played at high speed, and things do get missed and errors do get made.

"So, from that perspective, we’ve had him before. Hopefully, we know how to play within his outlook of the game, and put together a performance accordingly."

Louw, who has 74 Test matches to his name, is expected to be named on the bench for Sunday's clash. 

Kick-off is at 11:00 (SA time).
