England made it two wins out of two as they beat Argentina 31-12 at Twickenham on Saturday. Their victory was built on a fluid and solid first half but they will be disappointed and frustrated by their showing after the interval.
And the man who coached England to World Cup glory in 2003 said he would be asking some tough questions in the changing room.
"When you coach a team like England you choose your moment to throw a few tea cups and I think this is one of those moments," said Sir Clive Woodward on Sky Sports.
"I would be pretty mad to be honest - I think sometimes it is good to be mad when you have won a game. The first half was so good, a huge improvement from last week but then to see the pace just drop off in everything they did was disappointing.
"I would want some answers why. You don't lose your temper as a coach but a week before the All Blacks, to see us play so poorly in the second half, well I would want to ask some questions.
"England lost all their momentum in the second half, the pace of their game went; it looked like they had one eye on next week.
"England did say they wanted to win both of these games before the All Blacks and they have done that, so that is progress. They have to pick up for next week and perform for 80 minutes - if they only perform for 40 minutes like they have done today and like how they did against Australia then they are going to get beaten.
"If they take all the good from the last two games and put it together then next Saturday we could be in for another great game like we had a year ago."
Sky Sports expert Stuart Barnes echoed Woodward's concerns about England's lack of consistency.
He said: "England were very strong, very quick and very slick in the first half. In the second half they were almost anemic.
"They took their eye off the game, they got too lateral, they don't have a back five ready to take on the All Blacks.
"The final try was a reminder of what England do have - big, powerful ball carriers who can beat any team in the world around the fringes.
"If they can put the first 40 minutes of rugby together for 80 they could give New Zealand a go; if they play anything like as loose as they did in the second-half, it will be embarrassing."
