A win of 6 points or more would see Connacht qualify for the quarter-finals of the Heineken Champions Cup for the first time in their history.
Commenting on the team announcement, Andy Friend says:
“While our performance last week was good overall, there was a very real sense of disappointment that we didn’t get the win. Having said that, I know this group can bring their performance on another level, which is essential if we’re to reach the last eight.
We’ve a good record in the Aviva over the last two years or so and it’s a pitch that suits our style of rugby. Coupled with a strong travelling support behind us it’s set to be another great occasion.”
