Former captain Lawrence Dallaglio berated a "clueless" England after Saturday's home defeat by Scotland after Eddie Jones' reigning champions made a woeful start to their Six Nations title defence.
The visitors were the dominant side in all aspects as they won 11-6 for a first Twickenham victory since 1983 to reclaim the Calcutta Cup.
"England looked clueless. Not just for parts of it, all game," Dallaglio wrote in his column for Britain's Sunday Times newspaper.
"Whatever the cause, it's got to be sorted out quickly because that was as bad as it gets.
"This is not me being overcritical. It was there for everyone to see."
Dallaglio, who won 85 England caps as back-rower from 1995-2007, added: "The players need to take a very long, hard look at themselves and come up with some answers. I thought England didn't fire a shot."
Clive Woodward, the coach of an England team featuring Dallaglio that won the 2003 Rugby World Cup, was equally damning.
"The score flattered England, it was nowhere near that close. Make no mistake, this was a huge setback for Eddie Jones and the squad," Woodward wrote in his Mail on Sunday column.
"The team selected was fine -- I really liked the look of the team actually - but their game plan and execution was very poor.
"Owen Farrell was in a state of shock during the post-match interviews. If we are brutally honest England scarcely fired a shot."
Meanwhile Mike Brown, England's most-capped full-back, suggested in the same newspaper that veteran Australian coach Jones replace skipper Farrell at fly-half in a bid to revive the 2019 World Cup runners-up.
"Next weekend could be time for a change and I would put Owen Farrell on the bench and start with George Ford against Italy on Saturday," said Brown.
"Compared to his usual high standards Farrell was poor at Twickenham, with England wasting four-man overlaps and kicking the ball away."
