Exeter head coach Rob Baxter was delighted with their 31-14 victory over Clermont, saying it showed how far they have come in three years.
The Chiefs lost to the same side 46-12 at Sandy Park in 2012 but enjoyed a win on home soil this year, as they made a statement to Europe.
Now sitting top of Pool 2 ahead of Ospreys and Clermont before a trip to face the latter, Baxter is feeling good about his side's progress.
"The nice parts of it are, three years ago we were well beaten by Clermont, but now three years on we are second in the Premiership and we have won an important game of Champions Cup rugby. What this has given us is an opportunity to make next week a big week, whilst the win keeps the pool alive for us beyond next week," he told the EPC Rugby website.
"We seem to get asked if that was our best win on and off on a regular basis, but let's wait and see. If we get out of the pool at the end, then maybe we will look back at this night as the defining moment. Right now I think we will wait to see if it was the best game in our history because ultimately if we don't get out of the pool, it doesn't add up to very much, and that's the tough reality of it all."
By the end of this week it could be congested at the top of the pool, with Ospreys travelling to face Bordeaux-Bègles in the other game as Baxter looks ahead to an "interesting" business end.
"If you look at things in previous years, around 17, 18 points things can happen for you. We have 10 now, three games remaining, so things are starting to get interesting. It's up for us now to fight for it and keep things in our own hands, which is a nice place to be," he added.
