But the likes of British & Irish Lion Toby Faletau know they will face a far sterner test at The Recreation Ground against former European champions Bath.
Young fly-half George Ford was yet again the star of the show for his new club as he kicked all his side's points in 15-6 success at Bordeaux-Begles.
Ford picked up the Amlin Man of the Match award after slotting five penalties as Bath put themselves on the front foot in Pool 2 with what could prove a crucial win in France.
Bath won all six games and finished with 29 points from a possible 30 in last season's pool stages and their opening display at the Stade Chaban Delmas suggests they are keen to be equally successful this time around.
Bordeaux aim to bounce back from that loss when they travel to Stadio Maurizio Quaggia where one unwanted run is set to end.
Bordeaux have not won in their last eight European games. Manu Saubusse kicked their points but it was not enough to clinch his team's first win in Europe since December 2011.
Mogliano, in only their second European campaign, are still waiting for their first victory though will be buoyed by Tommaso Boni's late score at Newport in Round One.
