Wales hooker Ken Owens believes his country's mental toughness will be vital if they want to advance from Pool A at the 2015 World Cup.
The 28-year-old Scarlets stalwart is part of a 47-man interim squad who are currently training at altitude in Switzerland.
Wales are up against hosts England, Australia, Fiji and Uruguay in what has already been described as the tournament's group of death by rugby enthusiasts, but Owens is confident they will progress to the next round.
"I think it's something we're more than capable of doing, but one good team is going out of the World Cup at the group stage," he told the BBC.
"It's not the easiest group with England and Australia.
"Fiji are going to be no mugs and Uruguay coming to the Millennium Stadium will be looking looking to prove themselves.
"Every edge and every bit of mental toughness you can get is going to be massively important in this World Cup campaign.
"It's going to be interesting because whoever gets through our group is going to be battle-hardened going into the latter stages of the tournament."
