Previewing the game in the Galway Advertiser, Michael Bradley said: "In Rovigo we felt we achieved our objective in getting a bonus point. As a result there will be an expectation that it will be achieved this week.
"But our attention to detail, which will be critical, needs to be at the required level. This is an important match because it can put us in a good position to qualify.
"London Irish, as the favourites, will be difficult away, and they look like going through as pool winners, but we should be in a position to qualify."
