New coach Warren Gatland insisted the best was yet to come from his team.
Wales may have rewritten the record books by staging a remarkable recovery to beat England at Twickenham for the first time in 20 years but new coach Warren Gatland insisted the best was yet to come from his team.
Wales, overpowered up front during the first-half, turned a 19-6 deficit shortly before the hour mark into a 26-19 win as they scored 20 points in 13 minutes that, depending on your standpoint, were either magical or mindless.
"The result is everything," said Gatland, the third New Zealander to coach Wales after Graham Henry and Steve Hansen, following his first game in charge of his adopted country.
"It is a monkey off the guys' back. It will create self-belief going forward and put some pride back in the jersey. There are a lot of feel-good factors," the former Ireland and Wasps boss added.
The mood of the Welsh rugby public often veers between downright despair and overwhelming optimism with little in between.
Hopes of a Wales revival, following the team's failure to reach the quarter-finals of the World Cup, are sure to be high ahead of Saturday's match at home to Scotland.
But Gatland, doing his best to keep expectations in check, said: "It doesn't happen overnight. Physically, we've got got a lot of work to do. The potential raw material for this team is there. When we do get it right we will be a very good side.
"The next two games at home, against Scotland and Italy, are absolutely vital for us."
A first Wales win at Twickenham for 20 years looked anything but assured as, with Jonny Wilkinson kicking goals and his Newcastle team-mate Toby Flood crossing for a try, the visitors ended the first-half 16-6 down.
"Our first half was really poor," Gatland admitted. "The message was to hang in there and show a bit of character.
"We regrouped and the guys showed a lot of guts. They dug deep. This game is about mental toughness as much as anything else and the guys showed that today."
"The pleasing thing after half-time was that we took our chances, we took the three points and the longer the game went on the stronger we got, which was very surprising."
Crucially for Wales, man-of-the-match James Hook landed all six of his goalkicks and gave an assured display at outside-half in open play.
It was Hook, breaking the tackle of England wing Paul Sackey, who created Wales's first try for Lee Byrne before, minutes later, Mike Phillips crossed to finish a move that started with the scrum-half charging down Iain Balshaw's clearance kick.
"He's maturing as a player," said Gatland of Hook, one of 13 Ospreys players in the starting line-up. "But there are aspects of his game he needs to work on."
For Gatland's assistant Shaun Edwards - his old sidekick at Wasps - it was an emotionally-charged afternoon as it marked the day his late brother would have turned 25.
"It is a very difficult day for me and my family," said Englishman Edwards, the former rugby league great.
"It would have been Billy Joe's 25th birthday today - but thankfully these guys from Wales have put a smile on my mum's face on a very difficult day for her."
Wales did their new coaching duo, who won three Premiership titles and a European Cup together at Wasps, proud and captain Ryan Jones was in no doubt about their impact on the squad.
"They have tried to build a confidence and a belief that on occasions like this we can come here and impose ourselves," said the No 8.
"I felt we did that in the second half and to do it in an arena like this is really good."
