Louis Bielle-Biarrey scored a dramatic hat-trick to secure a 27-15 win for Bordeaux over Bristol Bears at Ashton Gate. The French winger's last try came in the final play, ensuring the holders finished top of their Champions Cup pool. Bristol's hopes of a guaranteed home knockout tie were dashed by the defeat.

Bristol had a dream start when former Bordeaux hooker Gabriel Oghre opened the scoring. However, handling errors in wet conditions proved costly, allowing Bielle-Biarrey and Nicolas Depoortere to put Bordeaux in control. Benhard Janse van Rensburg's late try set up a tense finale, but Bordeaux secured the vital bonus-point victory.

The result means Bristol remain second in the pool and will likely lose their home advantage in the last 16. Northampton now need only a standard win over Scarlets to secure top spot. Bordeaux, meanwhile, have secured home advantage until at least the semi-finals, cementing their status as reigning champions.
