Andy Friend insists Connacht will thrive on their status as no-hopers against Leinster at the Aviva Stadium.
The provinces meet again on Good Friday in Dublin after last Friday's exciting 26-21 round of 16 first leg victory for Leinster at the Sportsground.
If the westerners can muster a similar performance they will be in with a chance of making the quarter-finals for the first time.
Connacht boss Friend knows that his underdogs will be mostly written off as they chase a five-point deficit.
"No-one gives us a chance," he said.
"No-one gave us a chance last Friday night and probably no-one will give us a chance next Friday, which is ‘beaut’, because they’re the games that you just go and play, just go and do what you’re meant to do.
“And I know and we know that if we do that we can beat any team.
"As good as Leinster are, with all the quality they’ve got, we caused them some issues on Friday night.
"Now, they’ll be better next week but we will too. So we go up there with nothing to lose and everything to gain. That’s the image we’ll take.
"We won’t shy away from the areas where we thought we gave them access to the game.
"Their first two tries they were access errors from us, and there were a few more in the second half too where they didn’t finish things off.
“So it will be a very honest review as it always is."
While Leinster are used to playing Champions Cup games on Lansdowne Road, Connacht skipper Jack Carty points to his side's URC victory there in October as evidence that the stadium won't be a negative factor for the westerners.
"Yeah, massive," said Carty. "What gives us confidence is that last Friday was the first time that we probably went up against a fully loaded Leinster team and we went toe to toe with them.
"That will give us confidence. Look, any of the times we went up to the RDS - bar the one at Christmas - the two previous occasions, we were there or thereabouts.
"But it's a different Leinster team that we faced that day. As Friendy said, they’ll be better again this week - and we will be, hopefully.
"And, as Friendy said, no-one probably gave us a chance so it kind of gives us a free shot again.”
Meanwhile, Leo Cullen has called on Leinster fans to make the Aviva Stadium a cauldron in the way the Sportsground was for Connacht last week.
The westerners were roared into an early lead and also to a rousing second half comeback in the first leg of their Champions Cup showdown with the Blues.
Obviously it's harder to get that fortress feel for Leinster, given they will be away from their 18,000 RDS home and at the 50,000 ground on Lansdowne Road.
But Cullen, whose side hold a five point lead, admitted: "Absolutely, that's what you want.
"What's made the tournament so special is some of the days with the supporters in the packed grounds both home and away over the years, all the different sea of colours that I have in my mind - blue being my favourite colour obviously.
"But that's what you want to see. We missed it so much over a period, we didn't have it at all.
"So we're getting to that point where it's your knockout games and the crowd makes a huge difference in terms of how they drive the atmosphere of the game and the sense of occasion and all the rest of it.
"Look, for our guys, we get to run out at home and we know it means a lot to our group to represent Leinster in the first place.
"So whoever is lucky enough to get selected they know the responsibility that they have. Hopefully they'll be able to respond to that challenge and that responsibility."
