Wales v Argentina: We are making progress despite 'epic' defeat to South Africa, says Shaun Edwards Coming from a bloke who has refereed World Cup finals and many, many big games, that's obviously praise indeed. The breakdown in particular, the intensity, the aggression and the technique were outstanding. It was a step up but I thought we matched that, particularly at the breakdown. We got 10 contact turnovers, which is probably our most ever. Under coach Warren Gatland, who took over in late 2007, Wales have now lost 21 of their 22 matches against the southern hemisphere trio of New Zealand, South Africa and Australia. But Edwards is convinced that significant progress has been made. "Three or four years ago we would not have been able to hold on physically in that game," he said. We would have got blown away. South Africa are the most physical team on the planet. We were mixing it with them. There were no updates on Wales's injured players on Monday although it is already known that centre Davies is out of the forthcoming internationals against Argentina, Tonga and Australia. He was superb in his 12 minutes on the field, making two stunning breaks that meant he made more metres (40) in that time than any other Wales player managed in the whole match. Toby Faletau was next with 39 metres. "We will continue to assess a number of players," Edwards said. Obviously Jonathan Davies's injury is much more serious. We are just hoping that he is not going to be out of the Six Nations. That will be the case if Davies requires an operation on the pectoral muscle damaged in trying to prevent South Africa captain Jean de Villiers from scoring his side's first try. "Jonathan will be having scans over the next 48 hours," Edwards said. He is obviously a massive loss for us. Wales did not score a try, relying on Leigh Halfpenny's boot, but conceded three tries, much to Edwards" chagrin. "I was disappointed to concede three tries," he said, " but the last try was debatable and I think it was another big call that went against us. It was clearly offside, if it had just gone to the video referee. That third try was scored by Fourie du Preez after the scrum-half had kicked ahead, but when he had done so centre Jaque Fourie, who chased and made a delightful inside pass for Du Preez to run away to score, was indeed offside. It was 17-15 to South Africa then, and Edwards conceded that his players should have ensured the referee consulted the Television Match Official. "We maybe should have suggested that to Mr Rolland," he said. If we hadn't conceded that try, then 17 points would have been our best ever defensive performance against South Africa.
