Women's World Cup - Powell slams 'cowardice'
Claire Rafferty, a 22-year-old full-back who had come on after 80 minutes to make her World Cup debut, and injured skipper Faye White missed the fourth and fifth penalties respectively to seal England's exit.
But Powell was furious at the overall lack of courage shown by senior players who shirked the responsibility of stepping up to the plate.
Powell told The Guardian: "Three times I had to ask before anyone stepped forward. 'Where are you?' I was thinking, and then a young kid (Rafferty) is the first to put her hand up.
"And Kelly Smith was dying on her feet but she stepped up and took one. You've got to want to take a penalty, but other players should have come forward and they didn't.
"That's weak, it's cowardice."
Powell has said that she may quit as England coach, a role she has held for 13 years, to take on a developmental role in women's football.
