England backs coach Andy Farrell admitted his side have beaten in all areas by a rampant Wales in their Six Nations decider.
The Welsh ran out 30-3 winners to retain their Six Nations title and scupper England's Grand Slam ambitions.
Farrell said: "It's obviously the quietest the dressing room has been in a while. Four good wins on the bounce have got us used to a good feeling.
"The magnitude of the game and the loss means it is a pretty disappointed, dejected room at the minute.
"In the first 40 we had a big part to play in the game. We couldn't sustain any type of pressure in the Welsh half and at 12-3 down we were fighting for our lives.
"But then there was a lack of composure around halfway and they got a break. That made it 17-3, with which normal momentum is hard to get back from.
"And then from 60 minutes we lost our composure, as you'd expect in a game like this.
"All credit to Wales. I thought they beat us in every department today.
"We've been pretty good at winning lately. We haven't been in this situation before.
"Seeing pictures after the game, watching the Welsh lift another trophy - good luck to them for that, they deserved it - but we've got to learn the lessons and make sure it doesn't happen again next year."
Farrell says the performances of the Welsh players will be in his mind ahead of the Lions' forthcoming tour to Australia.
He said: "You don't just look at one game in isolation, you look at games that have been and gone and games coming up, such as the Heineken Cup final.
"But I can't deny, we look at pressure situations like these and their (the Welsh) guys stood up today."
