La Rochelle have endured a mixed campaign so far, with two wins from two in Europe, although Ronan O'Gara's side have been inconsistent in the Top14, currently sixth in the table.

"Pretty immense, pretty important [game] for us, and very exciting. A lot of history with La Rochelle in recent years, so we're expecting a tough and aggressive battle," he told RTÉ Sport.

"I think the players will
