Paul Collingwood believes Australia face a long road back as they look to recover from a 2-0 Ashes series deficit.
Collingwood, who scored a double century in a losing cause as England went 2-0 down on their tour of 2006-07 (going on to lose 5-0), knows how it feels to be in the position Australia find themselves.
England followed up their narrow victory in Nottingham with a comprehensive triumph at Lord's at the weekend to take a huge leap towards retaining the Ashes.
"You just sense, did they miss their opportunity at Trent Bridge?" he told Sky Sports. "If the score was 1-1 things might be a little different.
"You sense England have upped the ante a little bit, the confidence levels have grown and Australia's are diminishing, to be honest.
"It's tough to turn it around but at least they've got a bit of time to re-charge the batteries. They've got an opportunity at Sussex to score some runs in the middle.
"It's the batting line-up that's under pressure. England have been in this situation before in Australia and at 2-0 it's hard to bounce back.
"England will be wanting to keep them down and hoping Sussex can cause them a few problems next week."
