However, with other teams going well in other pools, Nigel Davies' side know that they require a win to ensure finishing as one of the top four seeds and therefore guarantee a home quarter final.
Speaking to the local media this week, Davies is happy with his team's progress in the competition, but knows that there is still work to be done.
"If you look at the groups and how they've panned out, there's no doubt in my mind that we've got the toughest group with two Top 14 teams and another Aviva Premiership side in London Irish.
"So, for us to be five from five at this stage, we can be very pleased with that. But it's important that we finish on a high note, with a big performance and a win which allows us a home quarter final, which would be a fantastic occasion."
Gloucester lost their last outing at Kingsholm, against London Irish in the Aviva Premiership, and that defeat insists Davies will mean that his side take nothing for granted against the French side.
"We've got be guarded against complacency. I'd like to think we've learnt our lesson on that from the London Irish game. I hope and I sincerely believe that the Gloucester crowd will see a different team this weekend."
