The English opening batter Crawley has indicated he had no knowledge of comments from skipper Ben Stokes about the team environment as no place for "those lacking fortitude".
Stokes delivered this message in multiple conversations following his team's defeat in the second match of the Ashes series against Australia previously.
Ahead of the third Test, where the visitors are staring at a series loss at the earliest opportunity, Stokes noted he had let his sentiment to "circulate freely" among the squad.
"I've done the necessary discussions in recent days that I required," said the England leader.
But, after the opener made a knock of 85 on the penultimate day in the third Test, he commented: "I didn't see that."
"I wasn't actively searching for it. We take everything that is said in the media with some skepticism," he added.
Frank Discussions and Consistent Messaging
Stokes made the "weak men" observation subsequent to England suffered a loss in the second Test to fall two matches behind.
The England squad afterwards took a break to Noosa in the gap between the second and third Tests.
Prior to the Adelaide contest, he revealed his team had held "raw" conversations and he had asked them to "show a bit of dog" in their battle to remain in contention in the series.
Yet, the Kent batsman stated the messaging from Stokes and coach McCullum had remained in line with their previous three years in charge.
"The atmosphere has been extremely upbeat, the same as always," said Crawley. "The focus is just trying to be optimistic, play our way, with great liberty. It felt like we could do something special going into this game."
Australia On the Verge of Rapid Ashes Triumph
Crawley's dismissal on day four came during a crucial triple-strike by Australia off-spinner Nathan Lyon.
The spinner's triple strike in a short spell – including the wickets of Harry Brook and Stokes himself – meant the chasing side six down for 207 in pursuit of a daunting target of 435 runs.
This means, the home team require just four more wickets on the final day to secure an insurmountable three-nil lead with three matches played.
A loss would prolong the English team's drought in Australia to 18 Tests and condemn them to a fourth successive overseas Ashes series loss.
This series will be completed in just 11 days of play – after England fell the initial matches in rapid time respectively.
The last time 1921, when the Australians sealed victory in the UK in eight days, has the outcome of the urn been decided more swiftly. The hosts have also won in eleven days on two other occasions in the modern era.
"This is disappointing," admitted Crawley. "Our goal was to win the Ashes and we're facing elimination at this point."
"There will still be significant pride at stake and we'll certainly approach it like that," he continued.
"The challenge has been tough. They're a very, very good side. It was always going to be tough coming here to face them. They entered as the front-runners and they've proven why."
Ollie Pope's Position Under Scrutiny
While Crawley's innings in the third Test probably answers doubts about his short-term future in the side, Ollie Pope looks under threat for his spot in the Melbourne Test on Boxing Day.
Pope fell for 17 in the team's second knock on Saturday, extending his modest returns versus the old enemy.
Across 16 Ashes innings, the Surrey man has never made a fifty and averages just 17.62.
Only one other England player since 1900 – Dennis Amiss – has featured as many times in the top order in Ashes Tests and returned a lower average.
But, the opener insisted any notion his teammate is under the microscope comes from "the media" – referring to the journalists – "not inside the camp."
"The squad is fully aware of his considerable talent," added Crawley. "He has had a productive year to be frank."
"He has produced some really good knocks. It is noise externally. There is no discussion like that regarding Pope amongst the players," Crawley finished.
