Head coach Leo Cullen hailed Leinster's 42-10 bonus-point triumph over Racing 92 after his star-studded team began their assault on the Heineken Champions Cup in spectacular fashion at a chilly Le Havre in France.

The Irish province, beaten in the final minute of last season's showpiece against La Rochelle, racked up six tries to demolish the three-time finalists in a Pool A opener switched from Paris to Stade Oceane due to a music concert.
