England coach Stuart Lancaster has labelled the Six Nations defeat of Wales at the Millennium Stadium as his greatest achievement in international rugby.
Tries from Anthony Watson and Jonathan Joseph on their Championship debuts helped England to an unlikely win in Cardiff, two years on from the harrowing 30-3 loss which shattered their title and grand slam hopes in 2013.
And 24 months on from the lowest point in his career, Lancaster has hailed victory as the finest of his tenure as England coach.
"I got interviewed by the TV after the game two years ago and it was probably lowest point of my coaching career at that point but today's win is certainly the highest point," he said.
"Because of two years ago and the lessons we've learnt and we didn't just focus of the performance two years ago but we focused on last year's performance and the way we finished the autumn series as well.
"Even though we had some new combinations and a few changes rom that Australia game we knew we had a good side and if we stuck to the plan which we did we could cause Wales some problems."
Despite being without a dozen first team players due to injury, England overawed a buoyant Welsh side, with Warren Gatland left flummoxed by a puzzling performance on home turf.
But the New Zealander refused to make excuses and praised England's strengthen in depth despite their length casualty list.
"They've got injuries but a huge amount of depth as well," he explained. "Their 10, 12, 13 combination did pretty well didn't it? I thought James Haskell was absolutely outstanding today.
"I can't see where you would argue that England are massively depleted. They have a huge amount of players, they have strength and depth and they came in and did them a job.
"Tom Wood would find it difficult the way James Haskell played. Sometimes you play with strength in depth and sometimes you don't."
