The Irish province make their third trip to the Continent on the back of a superb narrow four-point defeat at Pau last Saturday with coach Michael Bradley delighted to initially be away from home.
"It suits us better to be playing away in the first leg," said Bradley. "We will know exactly what we will have to do when Narbonne come to the Galway Sportsground the following Saturday - and that just might make all the difference.
"This will be the third season in a row that we will have played Narbonne in the tournament so we know them pretty well - you could say we are renewing old rivalries - and at the moment it is all square.
"In 2001 / 2002 both Pool 4 games went with home advantage, and it was the same in Round 2 last season, Connacht going through to the quarter-finals with just a single point advantage.
"The Parker Pen Challenge Cup is a tough and hard tournament - but also a great experience and tremendously exciting. We have guaranteed ourselves two more weeks in Europe and it is great for Connacht to be mentioned in winning ways.
"The performances against Beziers and Pau, two big physical sides, were most pleasing and our defence has been outstanding."You know when you go to France you are unlikely to see much of the ball and the work Mike Ford has done with us in that area has really paid off handsomely. I am happy with our defence."
