Reflecting on the 16-13 victory over Bayonne, head coach Eric Elwood was happy with his team's defensive efforts against the French side.
"Part of our discipline was that we couldn't afford to give away penalties in the red zone, unfortunately we gave them that platform a couple of times. But outside that, our discipline was good," he said.
"We did give away some cheap penalties that enabled them get into a position to put us under preasure, but thankfully we came out of it at the end."
Elwood feels that Leinster's pack is just as strong as Bayonne's set of forwards and that whoever wins the battle up front on Saturday will be in a very strong position.
"If we can get parity up front and be able to mix it up with them in the pack, then that's the winning of the game.
"Leinster have got big ball carriers, big internationals. But if our guys show the same attitude and hunger as last week then we'll be fine."
