Samoa is pooled with South Africa, England, Tonga and the US in France, but coach Michael Jones is not daunted.
"We have picked the squad on form and it's also a team we have been shaping for the last four years," he said. "It's very important to pick players we believe can play our game plan."
"We have a big dream," he said. "We have set our aspirations very high.
"The first step is to make the quarters. I believe we can get there, but we definitely want to take it another step and make the semis, and then to the finals, but it's a big dream. I believe we can make it."
