Michael Vaughan insisted England's top order had not become a "cosy" club after naming an unchanged side for the second Test against New Zealand starting here Friday.
During England's 2-1 Test series win in New Zealand in March, England took action after losing the first Test in dropping fast bowlers Stephen Harmison and Matthew Hoggard. But the batting order remained intact.
England haven't managed a first innings score of 400, the minimum total which usually puts an opposition side under pressure, in their last 10 Tests.
In the drawn first Test of this three-match series at Lord's they saw openers Andrew Strauss and Alastair Cook share their first century stand as a first-wicket partnership.
But both batsmen got out when well set after England's attack had dismissed New Zealand for a modest 277.
It needed a crafted hundred from England captain Vaughan to get his side to a total of 319, a first innings lead of just 42.
"I certainly don't think it's cosy," Vaughan said of England's top six.
"I see the way the lads train and I don't see any complacency in any of the batsmen," he also told reporters at Old Trafford here Thursday.
"What the lads have to do is just go out and play, play the moment and big scores we'll be round the corner."
But he admitted England's first innings returns were a concern.
"We really do look to try to get two players to a hundred in the first innings to get the big score. More often than not, one of us has got a hundred but then we've fallen short of the 400, 450, target we like to achieve."
"We are all playing well at times but not well as a collective unit. The most important thing is winning games of cricket. To do that you have to get 400 on the board consistently.
"I look back to India (in England) last summer, the way the ball swung around it was quite tricky. Sri Lanka's a tough place to bat and New Zealand can be tricky.
"But we are still better than the runs we've scored in the last year.
"I think this wicket is a perfect opportunity for us to get those first innings runs."
And with the likes of Owais Shah and Ravi Bopara waiting in the wings, Vaughan warned: "I don't think anyone's place is guaranteed with the strength in depth we have."
Although England added Hampshire quick Chris Tremlett to their squad, he didn't make it into the final XI, with Ryan Sidebottom, James Anderson and Stuart Broad retaining their places in a three-man pace attack.
"Tremmers is bowling well and this kind of wicket could suit his style of bowling but I fully believe the young lads deserve another crack," Vaughan said.
"I felt they all bowled well in spells at Lord's and they all could bowl well on this kind of wicket. They deserve another opportunity to prove what they are made of."
It was the fourth Test in a row that England had named an unchanged team and Vaughan saw parallels between now and 2005 when England, for the first four Tests of their victorious Ashes campaign, stuck with the same XI.
"This is the fourth game on the trot I've been able to announce the same team," he said.
"I've been involved in an England team a few years ago that was very consistent in the 11 players we picked and that achieved great results."
