But Bordeaux showed no mercy. Rayasi crossed on two further occasions, the second of which came after some spellbinding footwork to leave both Steward and Ollie Hassell-Collins for dead.
Outclassed, outfought and out-thought, the challenge now for Leicester is to ensure that there is a response. For Bordeaux, it might only be Toulouse who can stand between them and an historic European and domestic double.
