Ireland face France in a two-legged World Cup play-off with the first-leg to be played in Dublin on Saturday.
Given said: “We have to believe.
“We know France are the favourites, but that’s fine with us, it means there’s more pressure on them. We need to just play our own game and give it everything.
“We have two massive games in front of us, but I think we are in with a great chance of reaching the World Cup.”
