Ulster utility-back Charles Piutau has urged his side to have a big performance against Exeter Chiefs on Sunday to gain some traction in their run towards the business end of the competition.
The Northern Irish club desperately need the win as they sit third in Pool 5, tied on nine points with Bordeaux-Bègles, and a victory would mean going one step closer to making into the finals stages.
Piutau stressed the importance of getting the win and how much pressure his side are under.
"Our backs are against the wall and we need points," Piutau told the Belfast Telegraph.
"That makes our last two games must wins if we're to have any chance to make quarters. We don't want to come back to Kingspan with our last pool game against Bordeaux next Saturday rendered meaningless.
"This game against Exeter is crucial and we've got to put in a big performance. For the club it would mean a lot.
"Last year they just missed out. We want to improve on that but we have to focus on Exeter, there's no use looking beyond this game.
"Fingers crossed because it would be great for the supporters here and, to be able to play at that level, would be a great experience for guys who haven't been there before. It's a great opportunity and it would be great if we could make it happen."
