Robbie Keane insisted that the Republic of Ireland's World Cup hopes remain alive despite the 1-0 first leg play-off defeat by France at Croke Park.
Nicolas Anelka's deflected effort makes France favourites to qualify ahead of the second leg but the Irish skipper refused to throw in the towel.
"We have to be confident for Wednesday and believe we can win," said Keane.
"There's no question we can do it on Wednesday. We've been to big teams like Italy and got results."
Keane added: "It's not going to be easy but we have to believe.
"We have to go there, we have to get a goal and hopefully we can get two and not concede."
Reflecting on where the first leg was won and lost, the Tottenham striker added: "They didn't create too many chances but the one that counted cost us a little bit.
"We created a few chances, maybe not clear-cut chances but certainly half chances."
Striker Kevin Doyle, named man of the match after leading the line bravely, echoed his skipper's thoughts.
"We go to France needing a goal. If not two goals, then one to get into extra time and then we'll see what happens," he said.
"It was so close tonight. Their goal was not even a half chance, it was a lucky deflection.
"We had a few chances we made ourselves but just couldn't score.
"It's half-time and we have another game to go in Paris.
"We have gone to Italy against the world champions and we got a goal so why not in France?"
Meanwhile, France coach Raymond Domenech said that the play-off remained alive despite his team's away victory.
"I feel we are only halfway through," said Domenech.
