France and Wales will vie to become the European representative in the 2011 World Cup Final when they meet at Eden Park Saturday.
Both teams harbour realistic hopes of reaching the final in Auckland on 23 October, after overcoming mediocre starts and internal strife to reach the last four.
A long-awaited World Cup victory over England relieved some of the pressure on a beleaguered French squad but coach Marc Lievremont warned nothing less than victory over the Welsh would suffice on Saturday.
"A good match against England isn't enough to rid us of all our frustrations," the Frenchman told reporters.
"What we need as Latins is a hint of anger ... something that will give us impetus, and that is what we are looking for.
"Yes, it was a good match against England, but that wasn't enough to free us. We now need to make sure we don't miss this opportunity that we have been given in the semi-finals."
Reports of unrest in the French camp translated to uneven performances in the group stage, culminating with defeats against Tonga and New Zealand that led to criticism of Lievremont's management back home.
The French coach admitted he was fearful of the Wales but remained upbeat about his side's chances of reaching the final.
"Yes, I am afraid," he said. "Above all I am afraid of the Welsh.
"Right now we are running on adrenaline - I keep telling myself I can sleep in 10 days' times. I don't need much sleep generally, but it is true, I am more stressed right now.
"What we need to remember is that we had never beaten England at such a high level. That's something we can take strength from."
Wales announced Thursday that James Hook would replace the injured Rhys Priestland at fly-half for Saturday's clash.
Priestland is the only injury concern for Wales, who will be making their first World Cup semi-final appearance since 1987.
