SIR Clive Woodward has admitted he had sensed England's Grand Slam defence would be derailed by Ireland - but warned his European rivals that the world champions had drawn strength from the result.
Ireland became the first team to triumph at Twickenham in a Test match since 1999, emerging convincing 19-13 winners as England's quest for a second successive RBS Six Nations clean sweep was halted in dramatic fashion.
The Irish executed their simple gameplan to perfection, assisted by a shocking display from the World Cup winners, who were severely hampered by their misfiring line-out - with hooker Steve Thompson the biggest culprit.
"The line-out was just the tip of the iceberg when it comes to what went wrong," Woodward said.
"The guys in the line-out have been beating themselves up this week but they shouldn't be because the result was a combination of 100 different things.
"We got what we deserved at the weekend and we now have several training sessions to put everything right. I'm very aware of what happened - the standard of our performance was not something I ever expected to see.
"How we lost by just six points is beyond me. But it's just the check we needed - everyone has now been given a wake-up call, and that includes me. We didn't play well in Rome or Edinburgh and we knew we were going to lose sooner or later.
"We could feel the defeat coming before the Ireland game because it felt like we'd been skiing uphill all week. Playing for England is not about caps, it's about winning Tests. We're top of the tree and want to stay there, so it's good it's happened now.
"But just as we understand the reason behind our success over the last four years, we also know why we lost on Saturday - and that just makes you more confident. We are stronger because we know where we went wrong."
Woodward's troops will be able to redeem themselves in eight days' time when they play Wales at Twickenham, and the England boss has added two players to his squad in preparation for the match.
Leicester prop Julian White and Sale Sharks hooker Andy Titterrell have been called up for training at Pennyhill Park next week, and their presence should put pressure on Wood-ward's first choice front row.
White is on the comeback trail from knee surgery and Woodward will be keen to see how he performs for the Tigers against Northampton tomorrow, while the soon-to be retired Jason Leonard is also in the reckoning.
Full-back Iain Balshaw is included in the 28-strong squad despite suffering from a groin strain, while Mike Tindall and Danny Grewcock could return.
