Australia vice-captain Steve Smith has claimed to be "surprised" at the lack of action afforded to England fast bowler Stuart Broad during the visitors' dire Ashes campaign.
Broad was dropped for the emphatic defeat in Melbourne on Boxing Day that saw Australia retain the urn after just three matches of a one-sided series.
Only two players in English history can better Broad's career record of 120 Test wickets against Australia, and the 35-year-old vented his frustration at his recent lack of influence last weekend, also casting doubt over his Test cricket future.
England's selections have faced fierce scrutiny after Australia racked up an unassailable 3-0 lead, with all-rounder Ben Stokes publicly denying he has any desire to succeed the under-pressure Joe Root as captain.
Speaking at a news conference ahead of the fourth Test in Sydney, Smith said of Broad's absence: "We have been surprised. There have probably been two wickets that would have suited him well [in the first and third Tests, in Brisbane and Melbourne].
"He bowled well in Adelaide, and he's always been a good contest for me. He's got me out a few times, I've scored runs off him. I think it's been a decent battle.
"He and Jimmy [Anderson] are two world-class performers, they have been for a long time. Maybe we'll see them out here together this week, I'm not sure."
Smith, who has averaged 31.75 across the series, has turned his attention to putting in a strong individual performance in the penultimate test, as the hosts target a whitewash victory.
"It's been a little while since I've scored a hundred, but I got close in Adelaide," Smith said.
Smith's 93 runs in Adelaide's second Test was his highest score of the series to date, and the 32-year-old is looking to roll back the clock after averaging over 100 in each of the past two Ashes series, earning a reputation as England's tormentor.
"We've played on some pretty bowler-friendly wickets in the first three Tests, and it's been tough to get into a rhythm," he noted.
"But hopefully this week I can spend a lot of time out there, get a big one and help us continue to have success."
