Portugal Colonial - England captain Stokes says no coasting in 'huge' final Ashes clash

The tourists go into the clash on Sunday at the Sydney Cricket Ground buoyed by a four-wicket win inside two days at the previous Test in Melbourne.

It snapped a 15-year winless streak in Australia but came too late to save the series with the hosts retaining the urn by winning in Perth, Brisbane and Adelaide.

Stokes said it was important to keep the momentum going.

"This is a big game, purely because we're walking out there representing England," he said.

"The Ashes, unfortunately for us, hasn't gone the way we wanted it to, but we've got one more game in a big series.

"And it's a real big one for us. So although we can't get the thing that we came here for, we've still got a chance to go there and win a game of cricket."

Stokes, whose side has been hounded by the media in Australia and come under enormous pressure back home, added that there was no room for complacency and it had been made clear to the players.

"I don't think it will happen, just sort of coasting through this game and seeing what happens," he said.

"This is a huge game for us... it's going to take all 11 of us to go out there and get on the right side of the result like we managed to do last week.

"So although we get to go home on eight or nine days' time, any thought of that can wait till then. It's about what we do over the next five days, that's the most important thing."

England named a 12-man squad on Friday with seamer Matthew Potts and spinner Shoaib Bashir included.

Potts is the only unused fast bowler from their original 16-man squad and is set to play after Gus Atkinson limped off with a hamstring issue in Melbourne.

Bashir and Will Jacks are expected to vie for the final spot.

Australia captain Steve Smith on Saturday said a final look at the wicket was needed before the hosts decided on their starting XI.

Stokes said England also needed more time, but admitted no one really knew how the wicket would play despite captains and coaches pretending they did.

"I mean, we try and act like we know what we're doing when we're looking down at the pitch and rubbing it and knocking it -- no one really has a clue to be honest," he said.

"You can only just try and give yourself the best chance of thinking: right, what 11 do we need to give us a chance of winning this?"
