After winning two consecutive matches, hosts Australia will aim for a series clinching win when they take on beleaguered England in the third Ashes Test at the WACA Ground here on Thursday.
In the first two matches, the Australians proved superior in every department of the game as the hosts beat the Joe Root-led side by big margins.
On paper as well as on the field, the Australian side looked solid.
For England, on the other hand, it will be an uphill task to stay alive in the series as they have not won a match here since 1978.
Apart from the game, the English team is also battling off-field issues. So it might be tough for them to remain focused on this Test match.
"As professionals -- with the young kids watching and hearing all the news -- it's very important we are on our best behaviour. Off-field behaviour needs to improve and we all know that," England spinner Moeen Ali was quoted as saying by the International Cricket Council (ICC) website.
Australia also gave a hint that all-rounder Mitchell Marsh might be included in the squad for the WACA Test.
"Other people might be unlucky to miss out but Mitchell fills the role we need for this particular Test match," Australia coach Darren lehmann said.
"As a batter, he was in some good form. But we needed his bowling as well. Now he's bowling, we can consider him," he added.
Meanwhile, senior batsman Cook says the world has changed for English cricket in the wake of the damaging Ben Stokes affair, and warned the team cannot afford any more "mistakes".
The star all-rounder is currently banned from the international game while authorities probe his alleged involvement in a late-night fight outside a nightclub.
Cook admits his side has been slow to learn from the fall-out.
Dubbed a "behavioural cleanskin", Cook senses England should have learnt their lesson months ago that standards would be intensely scrutinised in the wake of the Stokes scandal. "It has been a very strange thing. The world has obviously changed for the English cricket team from September. We have taken a couple of months to really realise that. These last two incidents have proved that. I've seen words written down, 'trivial misdemeanour at best', but since the Stokes incident times have changed for the English cricket team."
Cook was referring to further off-field alcohol-related scandals involving Jonny Bairstow and Ben Duckett on the tour of Australia.
"It's sad in some ways because we have always been a bit different to football and been able to go under the radar a bit and enjoy playing cricket for England and enjoy seeing the country outside that," Cook said.
