England closed day four of the second Ashes Test needing 178 more runs for an historic victory in Adelaide.
The Three Lions will start day five on 176/4 having been set 354 to win – which would represent their highest ever fourth-innings run chase in Tests – with captain Joe Root 67 not out overnight.
Earlier in the day, James Anderson took his first five-wicket haul in Australia as the hosts were bowled out for 138.
Australia started the day on 53/4 and England looked to continue their momentum from day three, with Stuart Broad crashing a bouncer into Nathan Lyon's helmet early on.
It seemed to shake up the nightwatchman and he was soon dismissed by Anderson for 14, spooning straight to Stuart Broad at mid off.
Anderson then removed the out-of-sorts Peter Handscomb as the Australia batsman attempted to guide the ball down to third man only for Dawid Malan to take a fantastic diving catch.
Chris Woakes then took the wicket of Tim Paine thanks to a magnificent catch in the deep from Craig Overton, before the seamer took his second of the morning as he clean bowled Shaun Marsh.
Anderson completed his first five-wicket haul in Australia – and 25th in Tests – when Mitchell Starc top edged high into the air for Moeen Ali to take a simple catch.
Craig Overton then claimed the final wicket of Josh Hazlewood as Australia were bowled out for 138, leaving England with a target of 354 to win.
Set a record fourth-innings run chase for an England team, the tourists' openers made a solid start, Mark Stoneman taking the attack to Australia with some crunching boundaries.
But the first-wicket stand of 53 was broken when Alastair Cook was trapped lbw by Lyon, with the decision given on DRS.
His opening partner followed with just one more run on the scoreboard, with Stoneman edging to Usman Khawaja off Starc for 36.
That brought captain Joe Root to the middle and, along with James Vince, he saw England through to dinner on 68/2.
The lights came on after dinner and Australia made a quick breakthrough when Vince loosely chased a wide delivery from Starc and edged to Handscomb at first slip.
Root and Malan saw England through most of the remainder of the session, with the captain passing fifty and looking in good touch and Australia frustrated as Steve Smith lost both of his reviews.
Twenty minutes before stumps, Australia made the breakthrough when a ferocious ball from Pat Cummins nipped through Malan's defence and smashed into his off stump.
“The game is still in the balance. We’ve got six wickets to get effectively as many runs as we’ve already got so we are in a good position, the wicket’s still good. It’s a matter of taking it each ball at a time.”
Stat of the Day
James Anderson's figures of 5/43 were his best ever in Australia.
