Robbie Keane has challenged his Republic of Ireland team-mates to come off the pitch at the Stade de France with no regrets.
The Republic face a make-or-break World Cup play-off decider against Raymond Domenech's star-studded French team, who left Croke Park on Saturday night with a precious 1-0 lead.
But, skipper Keane remains convinced their destiny is in their own hands.
He said: "As a team, we know exactly what we have to do - we have to go out and perform and make sure we have got no regrets.
"Overall, in the campaign itself, we haven't lost away from home and that has given us a lot of confidence.
"The manager has instilled that into us because the performances away from home have certainly been good"
"It has been a decent campaign for us - but it will mean nothing if we don't produce tonight.
"We are in this campaign to be at the World Cup and tonight will decide it."
Ireland have won only one of the previous five play-offs in which they have been involved over the years.
No side has ever reached the World Cup finals after losing the first leg.
But Keane said: "We know exactly our job that we have to do and, if we don't do our job, we won't be going to the World Cup, it's as simple as that.
"By no means is it going to be easy but I certainly believe, with this squad of players we have, there is certainly a twist in this game, there's no question about that."
Saturday's clash at Croke Park was marked by a series of furious confrontations on the pitch.
The bust-ups were sparked by Lassana Diarra's comments to Keith Andrews - which he has since denied making - suggesting the Republic's dream was at an end.
But French Striker Thierry Henry does not feel the Irish will be out for retribution.
"As I said on English television, I do not expect anything," the Barcelona striker said at France's Clairefontaine training base.
"They are a team that will play, as they usually do, to their abilities and aggressively in the proper sense."
"The plain truth is that when we get on the field it will be 0-0. We will approach this match as if it was a one-off."
