La Rochelle thrashed Enisei for the second time in quick succession as they followed up last weekend's 82-21 success with a 64-26 victory in the European Challenge Cup on Friday.
Having run in 12 tries in the reverse fixture in Russia, the French side took their tally to 22 in two games by racking up 10 scores in another comfortable success.
There were nine different try scorers – with full-back Romaric Camou the only man to cross twice – as flanker Kevin Gourdon and Paul Jordaan were among the others to dot down, with Enisei having to play the final 53 minutes a man down following Maxim Gargalic's red card.
Northampton Saints got their campaign up and running against the Dragons by claiming a 35-21 victory.
Most of the damage was done early on as Northampton raced into a 21-0 half-time lead when their opponents were down to 13 men due to Lewis Evans and Adam Warren's yellow cards.
In Friday's other game, French side Agen secured a narrow 20-19 success over Italian club Benetton Treviso.
