Lawrence Dallaglio has vowed that England will be competitive in Saturday's second Test against New Zealand - and claimed that changes are inevitable.
England head coach Sir Clive Woodward intends naming his line-up on Tuesday, with several players sweating on starting places.
Woodward has promised not to over-react following Englands 36-3 drubbing in Dunedin, when the world champions suffered their heaviest defeat for six years.
But the axe looks certain to fall, both up front and behind the scrum, as England find themselves facing a huge test of character.
Inevitably there will be changes, because you cannot lose by that many points and not look at certain positions, said England skipper Dallaglio.
We have come down here to be competitive, and thats exactly what will happen in the next two Tests (against New Zealand and Australia).
Any defeat is disappointing, particularly to those who are not used to losing, and I havent lost many in the last couple of years.
We must not forget we won the last 12 meetings with southern hemisphere teams before the Dunedin Test, and while we have lost heavily, a lot of hard work went into creating that record and we must bounce back.
While the All Blacks ride a crest of a wave, England must effectively start again after being left floundering hopelessly in the blocks.
I know how hard it was to get England to the top - there were inglorious defeats along the way - and lets remember the pain that was suffered before the success came, Dallaglio added.
We became world champions, and the only difference is that the learning has to be done very quickly.
The real strength of a player is how he responds to failure - it will be the true measure of this team.
If we dont get certain basics right, then we will get well beaten here, and we must play our game with the passion and emotion that is required at this level.
Everyone who faces England, automatically finds that level because we are the world champions. Our passion has to come from every player, and I dont know why it wasnt there in Dunedin.
The scoreline does look very damaging, but it was down to several missed tackles that let them in for what I consider easy tries at this level."
