Captain Alastair Cook says it will take a monumental effort to hold on to the Ashes as England bid to defy history and fight back from 2-0 down against Australia.
The rampant Australians cruised to an emphatic 218-run victory in the second Adelaide Test, less than an hour into Monday's final day, to follow up their crushing 381-run win in Brisbane.
Cook, with his own form under scrutiny after scores of three and one in Adelaide, said the tourists would have to turn things around quickly in the third Test in Perth, where they have not beaten Australia since 1978, to keep the series alive.
No England side has come back from 2-0 down to win an Ashes series, but Cook's team only have to draw the series to hold the urn.
"It's certainly not impossible. A lot of people who'll be sitting in this room and outside will probably give us no chance," Cook told reporters.
"But if we believe in our dressing room that the urn's gone, then it might as well have gone. Two-nil is obviously not a great situation to be.
"It's going to take a monumental effort from us to do it, but we're the only guys who can turn it around."
Cook said although there was only a three-day turnaround to Friday's third Test there was enough time to work on their problems.
"What's gone on in the past is of no relevance whatsoever. You can say that we haven't won there for however many years, it's of total irrelevance to this team," he said.
"We have to go there as this side in 2013 and deliver something very special or we're not going to do what we've come to do.
