Stunning successes at Castres and Northampton in this season's Heineken Cup pool stages and a 20-17 win over this weekend's opponents two years ago have shown the Scarlets they can compete with the best away from their home base in Llanelli.
And while Davies admits that setting off for the continent is always a tough prospect, he will be telling his team to head south in high spirits.
"That's very important. You have to believe you can win matches," Davies told ercrugby.com.
"It's always tough in France. The Welsh sides haven't got the best of records over there, but I think we've probably got the best of the lot in terms of results.
"The fact that we've gone to France on several occasions - and once this season - and won, just gives you that little bit of an edge knowing that you can go there and get a result.
"We've won away in France, we know that we can also beat the Northampton's of this world away from home and we can go away to Munster and run them close.
"We're a lot more mature in terms of our belief in what we can do now than when we lost at Toulon in 2010. We went over there and were sort of overawed by that occasion. As a result we fell to a heavy defeat to what was a star-studded side.
"Rugby's about individuals and the team and it's about belief. We have a lot more belief now on the basis that we've won a lot more games together."
The Scarlets have a proud history in Europe, both before and after the advent of regionalism, but a series of positive showings over the last 17 years haven't yet resulted in silverware.
Llanelli reached the semi-finals of the Heineken Cup in 2000 and 2002, as well as the quarter-finals in 1997, 1998, 1999 and 2003, while the Scarlets were in the last eight in 2004 and the final four in 2007, plus the knockout stages of the Amlin Challenge Cup in 2010.
This season has already seen them feature in the LV= Cup semis and Davies says he now has his heart set on turning potential into prizes.
"It's a big goal of ours. From the outset of this season I said I wanted to get this team into as many play-offs as possible," added the ex Wales centre and caretaker coach.
"That in itself is experience and exposure to playing a certain type of rugby. We've done it in one tournament, albeit we weren't happy with our performance in the semi-finals of the LV= Cup.
"We're now in the play-offs of the Amlin and we'll learn from that experience in the LV and hopefully take that into this quarter-final.
"We went to Brive a couple of years ago in the pool stages of the Heineken Cup and got a win that helped us get into the Amlin quarter-finals so we know the place well.
"It's quite similar to our home base in Llanelli. It's quite a rural town and they've got a supportive crowd with a strong squad that's got lots of talent within it. They've had some good results, have got some quality players, and we're mindful of that.
"This is a really exciting competition. It's the quarter-finals in Europe and I think that we have a real opportunity to do something in the tournament this year. But we have to overcome this hurdle first."
