Daly's counter-attack score meant that England overcame a two-point deficit entering the closing stages of a pulsating Principality Stadium clash.

But it could have been a different story had Wales not got the so-called exit strategy wrong close to their own line.

"What happened was that we broke off structure," Wales assistant coach Edwards said.

"From any unstructured turnover, where the backs turn the ball over, we are supposed to go two rucks (in order) to get our backs back up on their feet to fill the pitch.

"We didn't do that. We passed it back to the kicker after one ruck, which was a mistake. It should have been two rucks.

"I don't think (centre) Jonathan (Davies) expected the ball because he expected a two-ruck exit play. That is probably one of the reasons why his kick wasn't as accurate as normal.

"But everyone makes mistakes. If one of us makes a mistake, we all make a mistake together.

"I always say to the players if they miss a tackle, I miss a tackle. It's not a matter of us and them, it's a matter of we.

"Our kick-chase wasn't set up because we expected it to go another ruck after the turnover. We didn't have our kick-chase in position. That was the issue."

Wales need to beat Scotland at Murrayfield in four days' time if they want to remain among the Six Nations title challengers.

And George North is on course to return from injury after he missed the 21-16 England loss because of a leg injury and was replaced in the starting line-up by Alex Cuthbert.

North, who has scored 28 tries in 66 Tests, trained on Tuesday and is in the selection mix for Edinburgh.

"We are looking very healthy all round at the moment," Edwards added. "We are definitely healthier than we were in the England week.

"We are selecting from a position of strength. George North has trained today and is raring to go."

Wales' interim head coach Rob Howley is due to name his starting line-up on Thursday, with North's potential return possibly the only change.

Bath number eight Taulupe Faletau featured off the bench against England and will be pushing hard for a starting place.

But Howley might opt against changing a starting back-row trio of Sam Warburton, Justin Tipuric and Ross Moriarty that performed so impressively in the England game.

Scotland, meanwhile, will look to end a nine-match losing run against Wales, having hit top form in beating Ireland before being defeated narrowly by France, although they are now without injured skipper Greig Laidlaw and number eight Josh Strauss.

"Any team that was within a hair's breadth - and that is a polite way of putting it - of a World Cup semi-final, you have to respect that standard of play," Edwards said of Scotland.

"They have got that momentum in the last few seasons.

"The World Cup is always the biggest test of you as a team. It's the biggest competition, and it is when as coaches you have the players for the longest period. We are very, very aware of the threat from Scotland.

"Obviously (full-back) Stuart Hogg is the talk of the town at the moment. In the Six Nations, he is one of the most dangerous players around.

"But everyone knows games are won and lost up-front, and that advantage line will be pivotal in who wins the game."
