Melbourne: England batsman Kevin Pietersen thinks Australia is still "very vulnerable" despite leveling the Ashes cricket series and claims the home team's new verbal aggression shows it is "under huge amounts of pressure."
In an interview with English media, Pietersen escalated vocal sparring between the teams, describing England's 267-run third Test loss at Perth as a "hiccup" and saying it was still confident of a historic series win.
In recent days, Paul Marsh, head of the Australian Cricketers' Association, said fear of the consequences of sledging had affected Australia's form and opponents had been quick to exploit its "weakness."
Marsh said Australia's win over England in Perth, which followed its innings and 71-run loss in the second Test at Adelaide, had resulted from a return to its "natural instincts."
Verbal sparring between the teams has noticeably increased. England wicketkeeper Matt Prior criticised Australian fast bowler Peter Siddle for giving him a verbal "send-off" after his dismissal in the third Test.
Siddle responded by saying England only complained because it lost.
"We won the game. That's why they're making such a big deal of it," he said.
Pietersen increased the ante on Thursday.
"When you're under extreme amounts of pressure, you talk a lot more," he said. "And the good thing about our team is, we're on a plateau. We do what we do.
"We made a hiccup last week. Yes, we were constructive in the criticism that we chucked around the team meeting about preparation and whatever. But we haven't come out and made any bold, huge statements about this and about that."
Pietersen said the English squad is keenly aware of Australia's vulnerabilities.
"There are a lot of areas in their team that are very vulnerable and we just need to do what we do and wipe the slate clean and forget Perth," he said. "Think about Adelaide, think about how well we did there and how well we did in Brisbane. We're absolutely fine."
England hasn't won an Ashes series in Australia since 1986-87 but Pietersen said the current team remained confident of revising history.
"I just think we've got a wonderful opportunity to do something that hasn't been done for 25 years," he said. "That's driving us all on to do something amazing."
Australian captain Ricky Ponting looks increasingly likely to play in Melbourne after breaking the little finger on his left hand attempting a slips catch in Perth. Pietersen said he was not surprised.
"I've played in a series with a finger broken," he said. "You just ring-block it. It's not a huge drama. You just numb it so you don't feel the pain.
"Ricky Ponting might bat without gloves; he's so tough!"
Australia wicketkeeper Brad Haddin said Ponting remained a key figure in the Ashes campaign despite his loss of batting form.
"He's our leader and we get a lot of inspiration from him," Haddin told a news conference Thursday. "He's been a great leader for Australia for a long time and especially with this group of players.
"You just have to see the turnaround we had from Adelaide to Perth to see the effect he has on the cricket team. It's very important that he plays."
