There were no real signs from Warren Gatland’s side in the build-up to the tournament that they were ready for a deep run on the biggest stage, but Wales hammered Australia in Pool B as they won all four of their matches.
That has set up a quarter-final clash with Argentina, who were stunned by a 14-man England side to open the tournament and have barely recovered, with tight wins over Japan and Samoa enough to get them over the line in Pool D.
Neither side has ever reached a World Cup final and a very tricky tie with either Ireland or New Zealand awaits the winners.
Gatland was parachuted back into the Welsh hotseat fewer than 12 months ago to steady their increasingly rocky ship for this tournament, and victory in this quarter-final would further validate that decision, regardless of what follows.
Date, kick-off time and venue
Wales vs Argentina takes place today, Saturday October 14, 2023, with kick-off scheduled for 4pm BST.

Wales vs Argentina team news
Wales have Dan Biggar back and fit to start at fly-half in a huge boost after a pectoral injury suffered in the 40-6 drubbing of Australia last month. Liam Williams also starts at full-back despite a knee issue that forced him off against Georgia last time out.
Gatland is without experienced No 8 Taulupe Faletau for the remainder of the tournament with a broken arm suffered in the win over Georgia in Nantes, with Aaron Wainwright switching to the base of the scrum on Saturday, Jac Morgan moving to blindside flanker and Tommy Reffell getting the nod at openside.
Adam Beard is back in the second row in place of Dafydd Jenkins having flown home for the birth of his child last week.
There is no Gareth Anscombe due to a groin problem, with fly-half cover for Biggar coming from Scarlets’ Sam Costelow instead.
Argentina have lost Pablo Matera to a hamstring tear, ending his World Cup in a major blow to the Pumas.
Lucas Paulos has been called up as his replacement, but it is Facundo Isa who comes into the side as one of two changes, while Tomas Cubelli gets the nod over Gonzalo Bertranou at scrum-half.

South Africa’s Jaco Peyper will oversee the quarter-final, with Englishman Karl Dickson and Italy’s Andrea Piardi his assistants. Marius Jonker is on TMO duties.
Wales vs Argentina prediction
The way Wales dealt with Australia showed they are not prepared to be intimidated by big-game atmospheres, even if they were pushed all the way by Fiji to open the tournament.
Since that close shave, the World Cup has gone exactly to plan for Gatland to dismiss pre-tournament fears they would be vulnerable to an upset.
Argentina, meanwhile, have not exactly impressed in overcoming Samoa and Japan to reach the knockouts.
Wales to win, by between 10 and 15 points.
Head to head (h2h) history and results
