England destroyer Glenn McGrath insists Australia can dominate the rest of the Ashes if they repeat their Lord's form.
"England still have some quality players," he cautioned, praising Steve Harmison's bowling in the first Test.
"Also the way Kevin Pietersen batted shows he thinks about the game and seems to have a pretty good game plan.
"We will have to overcome that but it depends on how we play. If we bat and bowl as well as we can, I don't think England are going to get near us."
McGrath made a mockery of pre-match claims that he was "getting on a bit" and "past his best", claiming figures of 9-82 as he won the man-of-the-match award.
"Things like that don't worry me whatsoever," he said. "Everyone talks it up a bit before the game but that is fine with me.
"At the moment I have never felt better bowling-wise, mentally and physically. To be honest I probably feel younger than I ever have."
If that is a worrying prospect for England for the remainder of the summer, the way Pietersen took to Test cricket was a major bonus.
His knocks of 57 and 64 not out on his debut only served to highlight the vulnerability of some of his more established colleagues
But the newcomer believes the rest of England's batsmen will respond to the challenge posed by Australia's bowlers in the second Test.
"Everybody has a bad day or a bad game but they are all quality players," Pietersen added.
"Most of our top order average over 40 and they will bounce back. They are positive players, we are a positive team and we are not going to hold our heads down.
"We have got a lot of positives to take out of this game - the opening partnership (in the second innings), Steve Harmison's bowling, a bit of my batting.
"It is a case of going out and squaring the series in Birmingham now."
