"They kicked 18 points and that's disappointing because our defence was good. When you're down here the calls can go either way."
Johnson's decision to recall flanker Joe Worsley was one major plus-point for England, with the 30-year-old producing arguably his best ever international display to nullify the threat of Wales' Andy Powell and Jamie Roberts.
But Worsley admitted that indiscipline was continuing to cost England dear.
"It was a huge improvement on last week," said Worsley.
"I know the Wales coaches (Warren Gatland and Shaun Edwards) and kind of knew what was coming.
"We are getting a lot of sin-bins. We're a relatively new team and probably hadn't been in that situation before and we reacted badly to it.
"Now that we've had that situation, hopefully next time that happens it won't be such a big issue.
"I know Warren and Shaun are such good coaches and Wales are such a fantastic team, but I'm gutted we didn't win."
