England coach Brian Ashton says he is running out of patience after his side's demoralising defeat by Scotland.
Brian Ashton's side suffered their second Six Nations defeat
Ashton's side were a pale shadow of the team who beat France two weeks ago as their topsy-turvy RBS Six Nations campaign took a turn for the worse.
"Patience is the biggest virtue a coach can have, but that starts to wear thin after a while," Ashton told BBC Sport.
"We have to think really seriously about what happened today and what's going to happen in the future."
England looked to be short of ideas in attack, as Scotland's limited game plan proved to be enough to reclaim the Calcutta Cup.
"It's very frustrating - we are bitterly disappointed, we said all week we had to be at our best to win the game," said Ashton.
"They just played the game of rugby better than we did in terms of their execution of the core skills.
"Their kicking game and their discipline was better and you're highly unlikely to win games of international rugby if you don't compete in those areas."
England fly-half Jonny Wilkinson kicked all of England's nine points to overtake Neil Jenkins as the all-time leading point scorer in Test rugby.
But Wilkinson's kicking from hand and all-round performance has again come in for fierce criticism.
Speaking on BBC Radio 5 Live's Sportsweek programme on Sunday, Ashton admitted Wilkinson had been some way short of his best.
"He didn't have one of his better games and he would be very frustrated in that," said Ashton.
Phil Vickery and Jonny Wilkinson were taken off in the second half
"Given the way he played against France, he will be disappointed and hoping to bounce back from it."
England captain Phil Vickery, who was taken off in the second half along with Wilkinson, was just as upset as Ashton after the defeat.
"Scotland came out on the back of a disappointing result previously and deserved their victory," he said.
"It wasn't going to be pretty, but they did the basics better than us and we are bitterly disappointed.
"I have to be careful talking after the game, sometimes you talk with emotions rather than with your head.
"We have to analyse look at what went well and not so well. We have to get ourselves ready for Ireland coming to Twickenham next week."
