England still believe ''100 percent'' they can win the Ashes from 2-0 down, and are planning to start the series all over again in Perth.

Matt Prior issued a stirring battle cry at the WACA on Wednesday, insisting Alastair Cook's tourists have the mettle to make history as only the second team - Australia managed it in 1936/37 - to recover from defeats in the first two Tests to win the urn after all.

Sussex's Prior cites ''brutal honesty'' and a readiness to learn from mistakes as the methods by which England can win in Perth for only the second time, and first in 35 years.

England's wicketkeeper-batsman, back to form with a half-century in the 218-run defeat in Adelaide on Monday, has no doubt about the tourists' ability to defy the odds.

Asked if they can still win the Ashes this winter, he said: ''Absolutely, 100 percent.

''One thing I do know about this cricket team is that when we get to this place we come out fighting.

''You have no option.''

Cook's England will not seek excuses but, according to Prior, instead identify where they have gone wrong and put it right.

''You can sit there and sulk, moan, whinge and make excuses - but you will just get beaten.

''You have to get rid of all that, and fight."
