Walsh rugby coach Warren Gatland has questioned the mental stability of the English rugby team - labelling them chokers after their Six Nations fixture on Sunday morning (NZT).
"I look back at England over the past few years and when it has really mattered, I question whether they can win these big games," said Gatland.
England were up 13-9 with 12 minutes to go before Wales rallied and scored two late tries through Cory Hill and Josh Adams to win 21-13.
"We've had a record of being pretty good in those [big games]. We knew exactly where we were. We said to the players: 'They have no idea what animal is turning up this week,' but we did.
We always knew how important this game would be. We went through some pain last week in terms of how hard we trained. The message to the players was that there is no way anyone is training as hard as us."
It was the second time Wales have come from behind to win in this tournament, erasing a 16-point deficit against France to win by five.
"I think it paid dividends, not necessarily from a physical point of view but from a mental point of view. We said before we left the hotel that we would win today because we've forgotten how to lose.
"It was probably one of the best weeks that I've had with the team. The challenge now is not to be complacent and not to drop our levels."
