Watch: Peter Betham helps Clermont sink La Rochelle in O'Gara first game in charge

Former Leicester Tiger and Wallaby winger Peter Betham was in fine form for Clermont in their opening TOP 14 match of the season as he had a hand in all three of Clermont's tries helping last season's finalist to a 28-10 victory over La Rochelle.

Ronan O'Gara's first game in charge of La Rochelle was far from ideal with former All Black Tawera Kerr-Barlow being shown a yellow card in the 6th minute before Betham scored his first try and shortly after Betham's second La Rochelle were reduced to 14 men with Sila Puafisi shown a straight red card for a high tackle on Jake McIntyre.

Betham's first try came from a turnover at the lineout before a nice touch by Jake McIntyre sent Isaia Toeava through a gap which put Jacobus van Tonder into space with the South African finding Betham in support.

His second try came from a deft cross kick from Jake McIntyre which fell perfectly for two-time Wallaby.

Betham capped off his game as he dived on the ball from a chip over the top before he delivered a superb offload to  Judicaël Cancoriet to score.
