All-rounder Ben Stokes has no desire to take over as England captain as pressure mounts on Joe Root in light of the side's 3-0 Ashes deficit.

Root replaced Alastair Cook as England's full-time Test captain in early 2017 but has come under scrutiny with the side losing the Ashes in lopsided fashion.

The 31-year-old batsman was also in charge when England lost 4-0 to Ashes in 2017-18 and failed to win back the urn on home soil in 2019 with a 2-2 series draw.

Stokes looms as Root's obvious replacement as the side's vice-captain and arguably the only lock in England's best XI but he dismissed the role was on his radar.

"I've never really had an ambition to be a captain," Stokes said. "Captaincy is more than about setting fields, picking the team, making decisions out there in the middle.

"A captain is someone you want to go out and play for. Joe Root is someone I always want to play for.

"It's totally Joe's decision. He shouldn't be forced into doing it. I'm sure Cooky felt the same way. He did it for so long and when he knew his time was up, his time was up. Those discussions haven't entered anywhere near Joe yet.

"I don't sense that at all with Joe. He's brought this team a long way. He's done some great things. Obviously this series hasn't gone too well, not from a captaincy point of view, but from a team and results point of view."

Stokes, who has only managed 101 runs at 16.83 and four wickets at 62.25 this series, threw his support behind under-fire coach Chris Silverwood.

"Unfortunately, the captain and coach bear the scrutiny for [results], but there are 10 other guys out there in the field," he said.

"That's [the media's] job, to say, 'Should people step down?' At the end of the day, the most important people's opinions are those guys in the dressing room and they've got our thorough support.

"Chris Silverwood, exactly the same. He's a real players' coach. He stands up for you as individuals and players as well.

"All the hype in the media recently about their futures, it's your job to write that, but they know full well they have the support of everyone in there and that's all that matters."

The fourth Ashes Test starts in Sydney on Wednesday.
