Wales will target a third Rugby World Cup semi-final appearance in the last four tournaments when they tackle Argentina on Saturday.
The quarter-final clash in Marseille comes after Wales collected 19 points from a possible 20 to dominate the pool.
Here, the PA news agency looks at some of the talking points heading into the game.
Wales in the driving seat
It would have been fanciful seven months ago to identify Wales as possible World Cup semi-finalists, given a miserable Six Nations campaign that saw them win one game.
Head coach Warren Gatland has turned things around, though, masterminding an unbeaten group phase that produced key victories over Fiji and Australia.
In contrast, Argentina found it tough going, losing to 14-man England before posting an unimpressive win against Samoa and then qualifying as Pool D runners-up.
It is a first World Cup meeting between Wales and the Pumas since 1999, with Gatland’s team firm favourites.
Faletau loss a huge blow
Wales’ victory over Georgia last weekend was clouded by number eight Taulupe Faletau suffering a broken arm that ruled him out of the tournament.
With 104 caps to his name and a consistent ability to hit world-class standards, his absence cannot be sugar-coated, even if Wales have enviable back-row strength.
Big players produce big performances in big games, and few Wales players have delivered such quality so regularly than Faletau during his 12-year Test career.
The shows goes on, but one of its star performers has left the stage.
Form and history favours Wales
Former Wales flanker Richard Webster once said that rugby is a sport played on grass, not paper, but form and history strongly supports a Wales victory on Saturday.
Four successive wins since losing their final World Cup warm-up match to South Africa represents a longest unbeaten run for more than two years, while Gatland has a 100 per cent record as Wales boss against the Pumas of played six, won six.
Argentina have beaten Wales only twice in the last 11 meetings, and their World Cup performances so far do not suggest an immediate turnaround in fortunes.
Biggar to boss the show?
Biggar is back at fly-half after recovering from a pectoral muscle injury suffered against Australia almost three weeks ago, with his leadership and game-management vital to Wales successfully negotiating their quarter-final hurdle.
The 33-year-old, who has won 111 caps, will retire from international rugby after the World Cup, and he is likely to be front and centre in Marseille as Wales target a triumph that would take them on the road to Paris for the tournament’s final fortnight.
His influence cannot be understated.
Jac Morgan – captain marvel
While Wales’ cap centurions like Biggar, Faletau and George North – who makes a Welsh record fourth World Cup quarter-final appearance – have all made their presence felt in France, the relatively inexperienced Morgan has also operated at an impressive level on a consistent basis.
Squad co-captain with hooker Dewi Lake, 23-year-old Morgan led Wales superbly in key pool-stage victories over Fiji and Australia, while his performances warranted the rave reviews they received.
There is a calm, quiet authority about the Ospreys flanker, who revels in Test rugby’s unforgiving and unrelenting environment.
