Joe Root insists there is still plenty to play for as far as England are concerned, despite having already lost the Ashes series to Australia after a dire first three Tests.

A chastening innings defeat in the third Test at the MCG gave the hosts an unassailable 3-0 lead, with England now just playing for pride in the final two, starting with the fourth Test at the SCG in Sydney this week.

"You can dwell on what's happened so far, or we can look at the opportunities that present themselves in the immediate future," Root said. "That can be the making of some sides and the start of something, that's the approach we'll have to take."

The England captain – who received the backing of Ben Stokes on Monday – also insisted he will continue focusing on the job at hand as he dismissed topics surrounding his future.

"I need to make sure that my full focus is on these two games," he added. "First and foremost, I need to try to get the best out of the group, make sure we put in those performances we keep banging on about out there on the field.

"We'll worry about the captaincy at the end of the series. I've got two big games here to manage well."

Root will lead England as captain in a Test for the 60th time, overtaking the record of 59 set by his predecessor Alastair Cook.

England's preparation has been far from ideal, with four coaches – including Chris Silverwood – in isolation, with assistant coach Graham Thorpe set to lead in Silverwood's absence.

The fourth Test will be the Pink Test at the SCG, the traditional event to raise funds for the Jane McGrath Foundation, the charity co-founded by former Australia cricketer Glenn McGrath following his wife's breast cancer diagnosis in 2005.

The ex-bowler's attendance is in doubt, however, after he tested positive for coronavirus on Sunday.

England to decide whether to stick or twist

The tourists made some notable changes for the third Test that it would be fair to say did not have the desired effect, but whether they change things back is far from certain.

Rory Burns was dropped after scoring just 51 runs in four innings across the first two Tests at an average of 12.75, but fellow opener Haseeb Hameed has only managed 65 in six innings at an average of 10.83.

Zak Crawley replaced Burns, making just 17 runs in Melbourne, but for a player who has played so little cricket recently it might be considered more beneficial in the long-term to give him another outing.

Chris Woakes was also left out of the third Test after an expensive return of 149-1 with the ball in Adelaide, but the all-rounder could be brought back for his batting as his average of 26.25 is the third best England have in this series.

Stuart Broad could come back in having been a surprising omission for the first and third Tests, as referenced by Steve Smith in the lead up to the clash in Sydney.

Only two players in English history can better Broad's career record of 120 Test wickets against Australia.

Options not a problem for Aussies

While England are desperately looking for players to put together a competitive side, Australia are wrestling with the conundrum of whether to leave out a bowler who took 6-7 in the second innings of the last Test.

Scott Boland had a Test debut to remember in his home-ground of the MCG, taking England wickets in the second innings with astonishing regularity, but with Josh Hazlewood possibly being available again after injury, Boland could be the one to make way.

Travis Head will miss out after testing positive for COVID-19 and is likely to be replaced by Usman Khawaja. Head has somewhat surprisingly been the hosts' top batsman in the series so far, scoring 248 runs in four innings at an average of 62.00.

There have been some calls for spinner Mitchell Swepson to be given a game in preparation for Australia's tours of Pakistan and Sri Lanka later this year, but the SCG has not always been a kind pitch for spin.

England captain Joe Root urged his team to respond in "disjointed and challenging circumstances" ahead of the fourth Ashes Test in Sydney.

The tourists have already succumbed to yet another series loss Down Under before a ball has even been bowled in the penultimate Test at the Sydney Cricket Ground, having been outclassed in Brisbane, Adelaide and Melbourne.

England's task has further mounted heading into the next Test, which starts on Tuesday, with head coach Chris Silverwood leading a list of absentees from the backroom staff due to COVID-19 issues.

Alongside the coaching shortage, some local net bowlers for the England side have also been withdrawn due to coronavirus complications, but Root insisted the seeming crisis is an opportunity for his team to unite.

"It has made things disjointed and challenging but it is a chance to come together," Root told BBC Sport.

"We're trying to manage it as best we can. In terms of practice, it's obviously going to look very different.

"We've all just got to be good human beings, good professionals, help each other out where we can and try and get the best possible prep going into these last two games.

"Whether it be putting pride back into the badge, whether it be making sure that we get Test Championship points, [and] for individuals making sure that they're pushing hard to cement their spots in the team. There's a huge amount to play for this group of players.

"We've got to stay tight, we've got to stay together. And we've got to put in a performance on one of the great Test venues in world cricket."

Root enjoyed an outstanding 2021 on the personal front, finishing with 1,708 runs at an average of 61 – the third-best haul in a calendar year, only behind Vivian Richards (1,710 in 1976) and Mohammad Yousuf (1,788 in 2006). 

Indeed, Root scored 26 per cent of all of England's runs last year – the highest proportion of any player for their respective teams in 2021 – but questions have been raised over the 31-year-old's captaincy credentials.

Nevertheless, Root – who received the backing of Ben Stokes earlier on Monday – ensures he will continue focusing on the job ahead as he dismissed topics surrounding his future.

"I need to make sure that my full focus is on these two games," he added. "First and foremost, I need to try to get the best out of the group, make sure we put in those performances we keep banging on about out there on the field.

"We'll worry about the captaincy at the end of the series. I've got two big games here to manage well."

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.

India coach Rahul Dravid praised "phenomenal leader" Virat Kohli for keeping team morale high amid ongoing questions regarding his resignation as T20I captain and subsequent removal as ODI skipper.

Kohli confirmed before the T20 World Cup that he would leave his role as India skipper in the shortest format, though he does intend to carry on playing in the team.

The 33-year-old believed he would continue as ODI and Test captain but is now only the skipper for red ball matches, with Rohit Sharma leading the side in limited overs games.

BCCI chief Sourav Ganguly explained the selectors felt there would have been too much leadership in the white-ball squad had there been two captains for each of the formats.

Ganguly also claimed that Kohli had been asked to stay on as captain, though the batsman dismissed those claims and has opted against attending pre-match media duties since.

But Kohli impressed as India beat South Africa by 113 runs at Centurion in the first Test of their three-match series and Dravid hailed the superstar for remaining focused on the matter at hand.

Speaking at a news conference on Sunday ahead of the second Test in Johannesburg, Dravid said: "I know there's been a lot of noise on other issues a little bit, outside of the group, even leading into this Test match, but honestly, in terms of keeping the morale high, it's not been very difficult because, to be honest, it's been led by the skipper himself.

"I think Virat has been absolutely phenomenal over the last sort of 20 days that we've been here – the way he's trained, the way he's practised, the way he's connected with the group.

"As a coach, sometimes, leading into the series, you know that there's not really too much you can do once the game starts, or there's not too much you can control in the results. But what you're really looking to do as coaches or as support staff, we're looking to prepare well and get the team into a really good space. 

"And Virat has been phenomenal in that – the way he's led the team, he's been absolutely, truly a leader, and I couldn't speak more highly about him and the way he's committed to his own preparation, his own practice, and also just the way he's connected with the group over the last two weeks.

"On and off the field he's truly been a fantastic leader and a really good captain, so that's really helped in creating a really good space. I felt we were in a really good space leading into the first Test match, and a lot of that was led by Virat and his leadership really came to the fore. 

"It's not been hard, it's been a pleasure to work with someone like Virat, he's been a phenomenal leader, and even personally I think that he's in a really good space."

"I think he's been a real credit to himself and to Indian cricket over these last two weeks in spite of all the noise that's been there around him."

Dean Elgar was "shocked" by Quinton de Kock's decision to retire from Test cricket but says South Africa have to "get over it and move on".

De Kock dropped a bombshell after a defeat against India in the first Test at Centurion last week by calling time on his Test career at the age of 29.

The wicketkeeper-batsman revealed he wanted to spend "more time with his growing family" rather than continue playing for his country in the longest format.

Proteas captain Elgar was taken aback by De Kock's announcement, but knows his side cannot dwell on the loss of such an important player ahead of the second match of the series against Virat Kohli's team.

Elgar said: "I was pretty shocked. I wasn't aware this was going to happen, but sitting down with Quinny that evening and him explaining to me the reason.

"I very much respect his decision and fully understand the space he is in."

Opening batter Elgar said De Kock's decision to quit is another setback for South Africa, who have had issues to contend with on and off the field 

He added: "It's disappointing. Not having Quinny around is disappointing for me. It's something I need to get over because I know there's other talented players within our system that I need to give a lot of attention to now and that's perfectly fine.

"As tough as it is, it's one of those things you need to crack on with and get over as quickly as possible.

"The players respect the environment, we've realised we've had quite a few setbacks over recent times and this is just another one we need to be clever around and we need to get over because the game moves on. I don't see this affecting the players and them still being shocked about his retirement."

The Proteas start the second Test at the Wanderers on Monday striving to prevent India from sealing a first Test series win in South Africa.

Elgar expects a response from his side after India beat them at Centurion for the first time in the longest format.

"I don't think I can say the words that I've been saying recently, but we've had hard chats I have had a lot of talks with the guys, even if it's in a personal capacity," he said.

"I take the guys aside and just chat, give them a little bit of affirmation to put him in a better mind space."

He added: "Players have to take responsibility. You can talk and talk until there's action. I said to the guys: ''I need to see actions'.

"Test cricket is a hard and ruthless environment and if you want to survive and be successful in this format you need to ask yourself the hard questions and respond to those questions.

"That's the culture I was brought up with and I want the other guys to think about it. They're not bad players. They haven't become any weaker.

"They just need to be mentally a bit more switched on and understand Test cricket is bloody tough and you're facing some of the best bowlers in the world now. You need to put on your big boy pants and react to what's happened."

Stuart Broad says his biggest frustration over England's Ashes failure is the feeling that he has "not really done anything" in Australia.

Australia retained the urn less than halfway through the series when they hammered England by an innings and 14 runs in the Boxing Day Test at the MCG.

Broad was dropped in Melbourne, having taken two wickets in an emphatic 275-run thrashing at the Adelaide Oval after he and James Anderson were surprisingly omitted for the nine-wicket defeat in the first match of the series at the Gabba.

The 35-year-old has expressed his frustration over being omitted twice as the wounded tourists prepare for the fourth Test at the SCG, which starts on Wednesday.

"As a wobble-seam bowler, I feel as though I missed out on two of the best wobble-seam pitches in Australia," Broad wrote in the Mail on Sunday.

"Only playing once has made this a very disappointing trip, one that has not met my personal expectations.

"The biggest frustration is losing the Ashes, being 3-0 down and feeling like I've not really done anything. Not being able, as an experienced player, to influence a series while it's live is tough.

"But that is top-flight sport, and I am not the only one who will feel this way. Ollie Pope and Jonny Bairstow, guys who have played one or two games will feel the same, and it's part and parcel of touring."

Broad says he still has the desire to play for his country in the longest format despite such a painful tour.

He added: "Has it affected my hunger to play Test cricket? No. Looking at things pragmatically, I would argue that I won't get a better chance to take wickets than at Brisbane and Melbourne. But I must be ready for my next opportunity, whether that be in Sydney, Hobart or beyond.

"There is a long time between now and the tour of the Caribbean in March and I have never been one to make emotional decisions. So I'm not going to make any spur of the moment calls on my future.

"I feel fit, I've come back from the calf injury feeling strong and I'm taking wickets in the nets. That's all I can do given the lack of tour games and the tight schedule."

England have spent long periods in bio-secure bubbles during the coronavirus pandemic and Broad says the players are feeling the impact of restrictions imposed on them.

He continued. "This tour has taken its toll on all of us. Without sounding like making excuses, we may be at the end of our mental tether with Covid.

"We are the only team that has played solid international cricket throughout the pandemic and our multi-format guys had already done 50 days in a bubble before they turned up here.

"We spent day two of the Boxing Day Test match testing for Covid and having guys moving out of their hotel rooms, away from their families, so they were no longer classed as close contacts.

"When you are faffing about with external stuff like that, it drags your focus away from where it needs to be."

Under-pressure England head coach Chris Silverwood will be absent for the fourth Test in Sydney, having tested positive for coronavirus while he was already in isolation due to what was a seventh positive COVID-19 case in the touring party. 

England head coach Chris Silverwood has tested positive for COVID-19 during his team's dismal Ashes tour.

The England and Wales Cricket Board (ECB) confirmed Silverwood, who was already due to miss the fourth Test, had joined the number of positive cases in and around the team camp.

It emerged after the Melbourne Boxing Day Test that a member of Silverwood's family had tested positive.

That set up the possibility that Silverwood himself may have come into sufficiently close contact to be infected.

Silverwood was forced to isolate, ruling him out of the Sydney Cricket Ground clash with Australia, which begins Down Under on Wednesday. Now, a positive test means he must wait to rejoin the team.

England are expecting him to be available again to take the reins for the series closer in Hobart, starting on January 14. In the meantime, batting coach Graham Thorpe is stepping up to direct team operations.

In a widely reported statement, the ECB said: "England men's head coach Chris Silverwood has tested positive for COVID-19.

"Silverwood has been isolating in Melbourne since December 30 following a positive test from one of his family members. He will remain in isolation until January 8.

"Silverwood is asymptomatic and is fully vaccinated. He is expected to return to the England party in Hobart ahead of the fifth Ashes Test."

The news comes after England great Graham Gooch expressed dismay at England's inability to be competitive in Australia.

They have already lost the series, after suffering heavy defeats in Brisbane, Adelaide and Melbourne, with Silverwood's position coming under scrutiny.

Speaking to Stats Perform, former captain and opener Gooch said: "I'm bitterly disappointed because losing a Test match is one thing, losing a series is one thing.

"But, what's really concerning for me is the lack of competitiveness of our team against Australia not only in the match at Melbourne, but in the previous two matches. 

"They've outplayed us, out-batted, out-bowled and out-fielded us in all three Tests, in most of the sessions.

"We've had a couple of half sessions, which we've done well with Joe Root and Dawid Malan scoring a few runs, Jimmy Anderson bowling a brilliant spell to help England dismiss Australia at the MCG for 267. But apart from that, we've been lacking."

Off-spinner Nathan Lyon says there are no dead rubbers as Australia chases a 5-0 whitewash of England in the 2021-22 Ashes.

Australia leads the series 3-0 after three dominant victories ahead of the fourth Ashes Test starting on Wednesday at the SCG.

There has been speculation about the make-up of the Australian side given they have already secured a series victory with dilemmas on Josh Hazlewood's fitness and Scott Boland's place along with talk of a second spinner in Mitch Swepson.

Lyon, who has taken 12 wickets in the three Tests, insisted Australia were determined to pursue victory and pick the best side possible.

"There's no more dead rubbers - and I've never considered them when you wear a baggy green - firstly because there's the World Test Championship and we want to go 5-0 up," Lyon told reporters on Sunday.

"If the conditions suit then we pick the best team to win that Test to make sure we keep moving forward. The Ashes for me is the pinnacle but I'd love to be part of a Test Championship final to state our case for the number one team in the world."

Australia missed out on the World Test Championship final last year, finishing third behind winners New Zealand and India. The Aussies have won the past two Ashes on home soil 4-0 and 5-0 respectively.

Lyon endorsed fellow spinner Swepson, who is set to get Test opportunities in 2022 with tours of Pakistan, Sri Lanka and India to come.

"I love bowling in partnership with spinners for sure," Lyon said. "I've done it a lot in subcontinent conditions so if the opportunity does come to play two spinners I know we'll really enjoy building that partnership. We've been doing it in the nets but it's a lot different."

Hazlewood, who has missed the past two Tests with a side injury, is expected to train fully with the group on Monday and could replace Boland who took 7-6 in the second innings of the third Test.

England star Jos Buttler insisted that he has no intentions to retire from Test cricket despite a crushing Ashes series loss to Australia.

Buttler declared he would play without fear ahead of his first red-ball series Down Under but has since mustered just 96 runs from the opening three outings, averaging just 19.2 against Pat Cummins' relentless bowling attack.

The wicketkeeper is not the only England batter to have struggled, given Chris Silverwood's side have already succumbed to a series defeat against Australia before a ball has even been bowled in the penultimate Test in Sydney.

After Quinton de Kock announced he was hanging up his South Africa whites to focus on his young family and limited-overs cricket, questions were raised whether the multi-format Buttler would follow suit and arrive at a similar conclusion.

But 31-year-old knocked back those suggestions on Saturday as he expressed his commitment to the longest form of the game, despite England's beleaguered Test team struggling recently.

He responded to reporters questioning his plans to continue playing red-ball cricket: "It's certainly my ambition. I don't think I'd have put as much into it as I have done if it wasn't.

"I have fantastic family support – they're very supportive of me and my career, and make a lot of sacrifices for that. It's certainly maintained my drive and ambition to try and play [Test cricket]."

He added: "That's Quinton's own personal situation. As a huge fan of his, I'm disappointed that he's at that stage. I love watching him bat, keep wicket and play Test cricket. 

"I commend him for making a decision that's right for him. But I feel I've got that support and in a place where I want to try to make it work."

Amid speculation over Silverwood's future following another thrashing to the old enemy Australia, Buttler and his team-mates now have the chance to prove their worth in the final two Tests in early January.

And Buttler reassured that all of the England camp are pulling in the same direction as they look to play for pride with their series out of their reach.

"One thing is we're massively in it all together," he continued. "We live it all together and we want to play well for each other. It's frustrating for Chris he's not here with us [due to COVID-19] – another complication of the tour – but we're certainly very united.

"There is an overriding sense of disappointment and frustration with the situation we've found ourselves in. We certainly don’t want to be a team to lose 5-0."

England have a chance to right some of their wrongs when they next challenge Australia on Tuesday at the Sydney Cricket Ground.

Only so much of the blame for England's poor Ashes series can lie with captain Joe Root, according to former skipper Graham Gooch.

Australia have already retained the Ashes with two Tests to spare, having established an unassailable 3-0 lead, dominating the opening three matches in Brisbane, Adelaide and Melbourne.

Root has been one of the only England batters to perform well, going on to become the leading run-scorer as the nation's Test captain, a role he has fulfilled since 2017.

He will lead England out for a record 60th time in the fourth Test in Sydney, overtaking Alastair Cook's tally of 59, while 26 per cent of all the team's runs were scored by Root in 2021, with the Yorkshireman plundering 1,708 in total.

However, England have averaged just 187.5 with the bat in six innings, failing to score more than 300 in any of the first three Tests down under, and Root's leadership abilities have come under scrutiny.

But after Chris Woakes backed the 31-year-old to stay on, Gooch has also offered his support to Root, but suggested the skipper may need to take a more realistic view on his team's scenario.

"I like Joe a lot. He's a brilliant player; a world-class player. He's not a bad captain; I don't think it’s his fault," Gooch, who scored 8,900 Test runs for England between 1975 and 1995, told Stats Perform.

"But to keep saying we’re close to Australia, that we can feel it coming, and one good session or one good day is going to turn it around. I don't think that’s going to wash really. We've been comprehensively beaten.

"I think it's a bit galling for us ex-pros and captains to hear."

Gooch, fourth on the all-time list for runs scored as England's Test captain, also paid tribute to the victorious Australia, whose strong displays he feels have played a major part in the tourists' slump.

Asked whether he believed the outcome of the Series was down to the hosts' performances or a poor showing by England, he said: "I think it's a bit of both.

"I think you've got Australia doing what they do best. They're aggressive, they're ruthless. If they smell blood, they capitalise on it.

"It's not because England have been so poor; they have not allowed England to be successful."

England coach Chris Silverwood will miss the fourth Ashes Test after a family member of the touring party tested positive for coronavirus.

Silverwood's position has come under question after England's dismal form in Australia, with the hosts having already retained the urn by racing into a 3-0 series lead.

Defeats in Brisbane and Adelaide were followed by a capitulation in Melbourne this week, with the third Test not even lasting three days.

Silverwood will be unable to be in attendance for the fourth match of the Tour in Sydney, as England desperately search for a result in order to avoid a whitewash.

A family member who travelled to Australia has tested positive for COVID-19 in the latest round of PCR tests administered to the touring party, the England and Wales Cricket Board (ECB) confirmed.

Silverwood will therefore have to isolate for 10 days, along with his family, in Melbourne. Another round of PCR tests will take place on Thursday.

The fourth Test is due to start at Sydney Cricket Ground on January 5, with the series finishing in Hobart after coronavirus regulations in Western Australia meant Perth was unable to host the final match.

Veteran Australian opener David Warner has set his sights on one last crack at the Ashes on English soil in 2023 as he looks to bury his demons from 2019.

The 35-year-old left-handed batsman has defied his age with the third most runs in this Ashes series after being Player of the Series as Australia lifted last month's T20 World Cup.

Warner was part of losing Australian touring Ashes parties in 2013 and 2015 and was tormented by Stuart Broad in 2019 when he was dismissed by the seamer seven times in 10 knocks, managing only 95 runs across the series which finished 2-2 with the visitors retaining the urn.

"James Anderson sets the benchmark for older guys these days, we look up to him getting on in our days," Warner told reporters.

"Winning the Ashes here was obviously a big one. We still haven't beaten India in India, that would be nice to do.

"And England away, we had a drawn series but hopefully if I manage to get that opportunity, I might think about going back."

The 89-Test veteran has scored 7,551 runs with 24 centuries but battled during the 2019 Ashes in England.

"In terms of 2019, it was obviously in England so he [Broad] was able to get the ball to come back into us and away from us," Warner said.

"For me it was one of those tours where I didn’t back my game plan and I went too defensive, and I didn’t attack. That was my fault, and he bowled really well.

"Out here, they have obviously picked Ollie Robinson for a reason ... he’s averaging 21 with the ball, he’s had some success in England, he bowls a good line and length. I wouldn’t say I was surprised, they’ve done it before in Australia.

"They haven’t played both of them [Broad and James Anderson] too often here – you might see him [Broad] play next game, and maybe Jimmy misses it. I can’t worry what they’re doing, but from our perspective I think it’s great he [Broad] is not playing."

Warner also backed under-pressure opening partner Marcus Harris who scored a game-high 76 in the third Test at the MCG after managing only 38 runs in his previous four innings.

“His courage to keep fighting and working ways out to score runs when bowlers are bowling good lines and lengths, he fought it out really well and I’m really pleased for him," Warner said.

Chris Silverwood believes England can take "positives" out of a humiliating MCG thrashing that ensured Australia retained the Ashes less than halfway through the series.

Scott Boland claimed astonishing figures of 6-7 as the tourists capitulated to 68 all out in the morning session on day three, suffering a chastening innings-and-14 run defeat.

England needed a victory to have any chance of regaining the urn, but suffered a third hammering of what has been a painful series for Joe Root's side.

James Anderson had given them hope by taking 4-33 as were Australia bowled out for 267 on day two, but their batting frailties were exposed yet again on Tuesday.

Yet head coach Silverwood says it is not all doom and gloom for England and believes he still has the players' backing.

Asked if the players are stilt responding to him as head coach, Silverwood told BT Sport: "I think they are.

"We had a good honest chat after the last game [the defeat at the Adelaide Oval]. We just have to put performances together and start pushing back.

"It is disappointing for us all and the lads will be feeling that in the dressing room.

"But I have to give credit to Australia, particularly Scott Boland on debut and Pat Cummins and Mitchell Starc for their opening spell last night.

"We had a good honest chat after the last Test, we just have to couple those performances together and find a way of pushing back against this bowling attack and scoring runs.

"Yesterday we had a little bit of disruption in the morning [a positive COVID-19 test in the team's family group] and I think the way the guys applied themselves on the field and the way the bowling attack rallied and got us back into this game was a credit to them.

"The way we caught in the last innings was good as well and I think there are positives coming out of this."

Silverwood believes England can salvage some pride in the remainder of a series that was over so soon after it started.

"We want to take something away from this series and we want to come back and compete in the last two Test matches," he added.

"We do have some world-class players and some youngsters as well who are learning on the job constantly. What we have to do is try and give them some confidence, we know they have ability and we do back them.

"We have to give them the opportunity to come out and show what they can do in the last two Tests."

Boland's figures were the best innings figures by any Australian on Test debut in Australia since Albert Trott took 8-43 against England at the Adelaide Oval in January 1895. 

Joe Root has refused to be drawn into the discussion around the state of English cricket despite Australia retaining the Ashes in record time and insists the series is not over.

England were humbled by an innings and 14 runs at the MCG on Tuesday as Australia claimed a series-clinching victory for an unassailable 3-0 Ashes lead.

Australia will now chase a 5-0 whitewash over England who were ripped apart inside an hour on the third day, bowled out for a meagre 68 which marked the nation's ninth-lowest Ashes score.

Despite the apparent gulf between the two sides and the disastrous nature of the MCG defeat, Root remained upbeat about achieving something out of the series ahead of Tests in Sydney and Hobart.

The situation has led to discussion around England's Test team and whether the County system is preparing players appropriately to compete at the elite level but Root would not be drawn on that.

"The series isn’t over yet," Root said at the post-game news conference. "We've got two very big games. It'd be wrong to look past that.

"As a player you talk about the next hour or the next session or the every next ball and managing that to be the best of your abilities, that applies to me as captain of this team.

"We have to make sure we come away from this tour with some better performances and a win or two."

Root added: "We need to put some pride back in to the badge. We need to give people back home something to celebrate and look fondly back on from this tour.

"It's bitterly disappointing to be 3-0 down but with two matches to go we have to make sure we come away with a couple of wins."

Root refused to use England's internal COVID-19 issues as an excuse for their ordinary third day display as they lost their remaining six wickets for 37 runs in 15.4 overs after resuming at 31-4.

The England skipper added that he felt his side had fought back on the second day with the ball, bowling Australia out for 267 to trail by 82 runs, but were unable to sustain their fight once again.

"I actually thought the way we went about our cricket on the field was excellent," Root told Fox Sports. "We put them under pressure and got ourselves in a position where we were very much in this Test match.

"We need to be more like that more frequently throughout the last two games."

He continued: "We've just got to do things for longer. There's been small pockets but nowhere near long enough to get into a Test match.

"We know the areas we need to improve on. We need to stay strong and make sure we use the next two Test matches as a real opportunity to take something away from this tour."

Debutant Scott Boland was "speechless" after his remarkable 7-6 spell locked in Australia's Ashes series victory over England with an emphatic win at the MCG.

Australia retained the Ashes by winning the third Test in Melbourne by an innings and 14 runs with right-arm fast bowler Boland making history in an astonishing spell.

Boland claimed four wickets in 11 balls on the third day, dismantling England's line-up as they were skittled for 68.

Australia clinched victory inside 81 minutes on the third day led by Boland's heroics, winning the game inside two days and one session.

"I'm speechless," Boland told Fox Sports after the game. "Coming in today I thought we had a pretty good chance of winning but never thought it'd be over before midday."

Boland, 32, had played 80 first-class matches prior to his Test debut, with his previous best-ever figures being 31-7.

"That's my best-ever figures," Boland said. "I got a couple of seven-fors in first-class cricket but nothing happened that quickly."

Boland, who was named Player of the Match, was fiercely supported by his home crowd, receiving wild applause every time he returned to the deep after each bowling over late on the second day and early on the third.

"They were amazing," he added. "They supported me so much from day one. Going down there just gives you a real big buzz."

Australia skipper Pat Cummins said Boland's success, having stepped up with Jhye Richardson, Michael Neser and Josh Hazlewood unavailable due to soreness or injuries, was a great sign for the hosts.

"It's a great sign for the health of Australian cricket we've got so many boys to pick from," Cummins said.

"Scotty came in, we were confident he'd do well, not quite this well, but we know whoever steps in is going to do a great job."

England only lasted 15.4 overs on the third day, with Australia retaining the Ashes within 13 days of cricket this series.

Australia lead all the key statistics, with the top four batting averages (Travis Head (62.0), David Warner (60.0), Mitchell Starc (58.5) and Marnus Labuschagne (57.25)) and top three leading wicket-takers (Starc (14), Nathan Lyon (12) and Cummins (10)) emphasising their dominance.

"I think we've been relentless with bat and ball when we've had to be," Cummins added. "The bowlers turned up and owned that good area around the top of off stump.

"The batters have really earned their runs. Some partnerships, Marnus [Labuschagne] and Davey [Warner] have earned the right to bat long, they've left well.

"When opportunities presented they've been brave and taken on the game. All round everyone has contributed."

Australia can claim a 5-0 whitewash with victories in Sydney and Hobart in the remaining two Test matches.

"I think any Ashes series is where you try to make a mark in your Test career," Cummins said. "Back to last series 4-0 and the one before that was 5-0, that goes down in history.

"We've got a chance to start cementing our identity and [it] can be the start for the next few years."
