Australian selectors will keep faith with their current squad, and Michael Clarke as captain, for the series-ending Ashes Test at the Oval. But coach Darren Lehmann hinted the end of that match will be the beginning of an overhaul focused on blooding longer-term players who, with Steve Smith as their captain, are more likely to succeed in all conditions. 
When asked if the Ashes series would mark a period where the hierarchy went back to "square one", almost an end of an era, Lehmann replied: "Yeah, probably."
"For us it's about moving forward ... working out what our best line-up is in different conditions and making sure we've got players who can adapt between spinning wickets and seaming and spinning wickets and making sure they can cover both formats really well," he said.
"We've got a bit of thinking to do and reviewing what went wrong. It's about getting batsmen who can bat long periods of time and bowlers who can put pressure on, day in and day out."
Lehmann said his favoured approach of Australia playing "aggressive" cricket did not preclude them from playing defensively when conditions demanded, and waiting for an opportunity to fully implement their more aggressive strokes.
"I think England played good, aggressive cricket this series ... we just didn't adapt well to have times to play aggressive cricket, to stay in long enough to be able to get the bowlers into their third or fourth spells and be able to play aggressively then," he said. "England took us on and played really well. What we've got to learn is making sure we're staying in long enough to make big scores. First morning was tough work we know, but it wasn't a 60 wicket, there's no doubt about that."
If selectors elect to implement a hardline philosophy it could result in Chris Rogers not being given the chance to play on, if his healthy form during the Ashes prompts him to officially rescind his retirement plans, and 35-year-old Adam Voges being discarded despite his unbeaten half-century in the second innings at Trent Bridge.
"They've played well," Lehmann said. "Adam's struggled but played really well which is pleasing for him. So we just need to sit down and think about that, how we want to go about it and what we think the best future for Australian cricket is ... We're not afraid to make the tough call, but you've got to also look after Australian cricket in the right way and we've got to make sure we're doing the right things by the players both old and new."
