SHAUN Edwards says he will be “unbelievably disappointed” if Wales don’t at least match their 2011 World Cup semi-final.

Warren Gatland’s men will secure their place in the quarter-finals by beating Fiji in Oita on Wednesday but won’t be content with the last eight.

Wales should deal with minnows Uruguay to finish top of Pool D and earn an easier route in the knockout stages.

It is likely that they would face France or Argentina and avoid the half of the draw featuring England and New Zealand.

Wales make the semi-finals in 1987 and 2011 and the Grand Slam champions are being tipped as serious contenders for glory after their impressive win against Australia.

"We have been in the semi-final once, as a coaching group," said defence coach Edwards, who is set to join France after the tournament.

"I think the two games we've just won, if we don't win our next three, I will be unbelievably disappointed.

"Obviously, if you do win your next three, you are in the semi-finals and back to where we were in 2011.

"After the Australia game, and we knew we had a break (in Otsu), it was about rest, switching off and trying to even forget about rugby a little bit to recharge the batteries.

"We are in Test week now, we are fully focused on Fiji, and we saw a team last night that is a huge threat.

"We are excited about playing a Test match first and foremost, and obviously the fact it is a World Cup and we could top our group makes it even more special."

Wales, though, know from experience just how dangerous Fiji can be, losing a 2007 World Cup pool game to them in Nantes that meant they were dumped out of the tournament.

They gained World Cup revenge for that defeat four years ago, yet Fiji's second-half destruction of Georgia on Thursday showcased a team packed with blistering try-scoring talent.

"They are definitely one of the teams who you don't want to break structure too much," Edwards added.

"I am hoping we put in an 80-minute strong defensive performance.

"I was pleased with huge aspects of the game against Australia - we were under huge amounts of pressure in the second-half - but we have not put an 80-minute performance in yet at the World Cup.

"There are a lot of tactical things we will try to do. We won't change our defensive system much. We want to cut time down for opposition nines and 10s.

"We will look to tackle in twos as much as possible, and then if they get their hands free you have to squeeze in around those off-loads and trail the support runners.

"We are under no illusions about what they will bring. They are very well-coached and organised, and have that X-factor.

"They are definitely one of the best sides in the world at sevens, so that will cross over."
