The English opening batter Crawley has indicated he had no knowledge of statements from captain Ben Stokes regarding the team environment as no place for "weak men".
Stokes made this message in several conversations following England's defeat in the second Ashes against the Australians previously.
In the lead-up to the Adelaide Test, where England now face defeat at the earliest opportunity, the captain noted he had allowed his message to "drift around" within the squad.
"I have completed all the talking over the past two days that I needed to have done," said Stokes.
But, following the opener made a knock of 85 on the penultimate day in the third Test, he stated: "I missed those remarks."
"I didn't see and wasn't really looking out for it. We take anything stated in the media with a pinch of salt," he added.
Frank Discussions and Steady Philosophy
Stokes made the "weak men" observation subsequent to England suffered a loss in the second Test to go 2-0 down.
The England squad afterwards went on a holiday to a Queensland resort between the second and the upcoming matches.
Prior to the Adelaide contest, Stokes said his players had held "raw" conversations and he had asked them to "show a bit of dog" in their effort to stay in contention in the Ashes battle.
Yet, Crawley asserted the guidance from Stokes and head coach McCullum had remained in line with their previous three years in leadership.
"The atmosphere has been very positive, unchanged," said the opener. "It's just trying to be optimistic, playing our brand, with great liberty. It felt like we could do something special entering this game."
The Hosts Close of Historic Ashes Triumph
The opener's dismissal on day four was part of a crucial triple-strike by Australian spinner Nathan Lyon.
Lyon's three wickets in a short spell – he also bowled Brook and Stokes himself – left the chasing side six down for 207 in pursuit of a notional target of 435 runs.
Consequently, Australia require just four more wickets on Sunday's last day to move to an insurmountable 3-0 advantage after three matches played.
Defeat would prolong the English team's drought in this country to 18 Tests and ensure a fourth straight overseas Ashes series defeat.
The current battle is set to be decided in only 11 days of cricket – after England losing the initial matches in two and four days each.
Not since 1921, when the Australians sealed victory in the UK in eight days, has the destination of the urn been decided so quickly. Australia have also won in eleven days on two other occasions in the modern era.
"This is disappointing," said Crawley. "We came here to win the Ashes and now we are facing elimination now."
"There remains significant pride at stake and we will certainly approach it with that mindset," Crawley added.
"It's been tough. Australia is a formidable team. It was always going to be hard touring here to face them. They were the favourites and have demonstrated their quality."
Pope's Place Under Scrutiny
Although the opener's performance in Adelaide likely secures questions about his short-term place in the side, Ollie Pope appears under immense pressure for his position in the fourth Test on Boxing Day.
The Surrey batsman was out for 17 runs in the team's second innings on Saturday, adding to his poor record versus Australia.
Across 16 Ashes innings, the Surrey man has failed to score a fifty and averages 17.62.
A solitary other English batsman since 1900 – Amiss – has featured an equal number of innings in the top six in the Ashes and recorded a poorer average.
But, Crawley said any notion Pope is being scrutinised originates with "the media" – referring to the journalists – "and not within the team."
"We all know how good of a player he is," added Crawley. "He has had a productive year if I'm honest."
"He has produced some really good knocks. This is talk from the outside. There's no discussion of that nature regarding Pope in the camp," Crawley concluded.
