Fijians Peceli Yato and Alivereti Raka score twice as Harlequins suffered a heavy defeat in their Rugby Champions Cup opener at Clermont Auvergne, losing 53-21.

Both Raka and Yato showed dominance as they made a return to the competition after failing to qualify for last season’s tournament.

Clermont opened up a 22-0 lead inside 25 minutes.

Raka raced clear after pouncing on a loose pass, with Morgan Parra, who had earlier opened the scoring from the tee, adding the extras.

Yato then powered over for the first of his double, dragging the desperately challenging Marcus Smith behind him.
