Australian fast bowler Mitchell Starc has warned England's batsmen to expect an even tougher time in the third Ashes Test in Perth.
England succumbed to a 120-run defeat in the second Test in Adelaide, leaving them trailing 2-0 in the series with three matches still left to play.
The visitors have struggled for batting form for most of the series, with no Englishman having made a century so far, and lost six wickets for just 64 runs as they collapsed from 169-4 to 233 all out in their final innings in Adelaide.
A win at Perth, where England have won only once and not since 1978, would see Australia regain The Ashes, and Starc believes that the Perth wicket - which is renowned as one of the world's quickest - could see the Australian bowling attack improve and cause more issues for the English batsmen.
"The exciting thing is our bowling group can still get better," the 27-year-old told the Daily Mail.
"We've obviously managed to take 40 wickets in the last couple of weeks and do some really good things, but I think there's still a lot of room for improvement.
"I hope we see a nice, fast, bouncy wicket - a WACA of old - and we can get stuck into their batters again."
The third Ashes Test in begins on Thursday, December 14, with England knowing that defeat would mean sliding to an unassailable 3-0 series deficit and see Australia regain The Ashes.
