Andy Murray will face the surprise package of last year's Australian Open in Saturday's final of the Sydney Classic.

Blocking Murray's way to a first ATP Tour title since October 2019 will be Russian player Aslan Karatsev, whose gritty win over Dan Evans prevented an all-British final.

Evans won a marathon tie-break in the second set of that encounter but could not maintain the level as he lost out 6-3 6-7 (13-15) 6-3 to a player who caused a sensation by reaching the 2021 Australian Open semi-finals.

It was also a case of digging deep for Murray, who picked up a stellar win over American Reilly Opelka, triumphing 6-7 (6-8) 6-4 6-4 against the fourth seed and world number 25. Murray is ranked down at number 135, but this strong week has provided evidence he still belongs at a much higher level.

Three years have passed since Murray came to Australia and indicated he was close to retirement due to hip trouble. He has battled back against the odds to stay active, but his lone ATP singles final appearance since that point came at the 2019 European Open in Antwerp, where he beat Stan Wawrinka to land a surprise title.

Now he is back in another title match, for what will be just his fourth singles final on the main tour since the end of the 2016 season, when he reached world number one status.

Murray rifled 16 aces and no double faults, winning an impressive 88 per cent of points when he landed his first ball in court, and his serve was not broken at any point by Opelka.

He has 46 singles titles and dearly wants to reach 50 before calling it a day, with a glorious chance to land a 47th coming up on Saturday.

Karatsev, the world number 20, is not a player that Murray would underestimate. He was ranked 114th and largely unknown before going on his run to the final four in Melbourne last February, but he has since pushed on and should provide a stiff test for three-time major winner Murray.

"It's already been a great week for me, big progress from anything I've done in the last year or so, to string four matches together like this and against top players in Basilashvili and Opelka," said Murray. "I'll go for 47 tomorrow. It's been a good week, I've played better with each match, so hopefully I'll step it up again."

At the Adelaide International 2 event, Australian wildcard Thanasi Kokkinakis produced a stunning semi-final win over fourth seed Marin Cilic, battling to a 6-2 3-6 7-6 (12-10) victory over the former US Open champion, teeing up a shot at Frenchman Arthur Rinderknech in the title match.

Senegal failed to take advantage of their apparent superiority against Guinea as they were held to a 0-0 draw at the Africa Cup of Nations.

The Lions of Teranga reached the final of the 2019 tournament but are still awaiting their first AFCON title and better attacking play will be required for them to do so on the evidence of this Group B encounter.

Liverpool manager Jurgen Klopp was left to rue the absence of Senegal's Sadio Mane and Guinea's Naby Keita, as well as Mohamed Salah of Egypt, in their 0-0 EFL Cup draw with Arsenal on Thursday. But neither Mane nor Keita could provide the moment of magic to break the deadlock in Bafoussam, though it was not for lack of trying.

Guinea, for whom Keita played a game-high 18 passes in the opposition half, should have taken the lead in the 31st minute when Morgan Guilavogui shot straight at Seny Timothy Dieng after a counter-attack, while Mane created Senegal's best chance of the game in the 67th minute only for Bouna Sarr to skew hopelessly wide from close range.

Sarr's miss encapsulated a match in which the two teams combined for just three shots on target, though both should sail into the next round having each claimed four points from two games in a group with minnows Malawi and Zimbabwe.

Pep Guardiola's considers Chelsea boss Thomas Tuchel as "one of the few" managers he still learns from.

Guardiola's Manchester City play host to Tuchel and the Blues on Saturday in the standout match of the weekend's Premier League schedule.

City head into the game with a 10-point lead over second-placed Chelsea – only four times before have the Premier League leaders had a bigger lead over their nearest challengers after 21 matches.

On each of those occasions, the team with the lead has gone on to win the title, and victory over Chelsea could see City end the weekend with a 13-point advantage as long as Liverpool do not beat Brentford.

City will certainly be considered favourites given the impressive job they did on Chelsea at Stamford Bridge in September, only winning 1-0 but outplaying Tuchel's side practically throughout.

Despite that wobble from Chelsea and the fact City have a healthy lead at the summit, Guardiola still counts Tuchel among the few rivals he looks to for inspiration.

"He's so creative, one of the few managers I learn constantly from, to become a better manager myself," Guardiola told reporters.

"Excellent in all departments. I enjoy since he was in Mainz and Borussia Dortmund, always I enjoy watching his teams and the way he's playing, the approach.

"I think he's dignified and he makes world of football better. When you find a manager who always wants to be positive in the way they play, it's good."

Earlier in the day, Tuchel revealed his regret at Chelsea going too defensive in their clash with City at Stamford Bridge.

City were the far greater threat, attempting three times as many shots as Chelsea (15 to five), who did not test Ederson once.

Chelsea accumulated just 11 touches in the opposition's box compared to City's 34, while the visitors' 1.47 expected goals (xG) suggested Tuchel's side were somewhat fortunate to concede just once.

Tuchel's comments would hint at Chelsea turning up in Manchester with a more positive approach, and that appears to be what Guardiola is preparing for.

"I can't imagine what is going to happen. If he didn't like how they played at home, they play different away," he said.

"Seeing the Liverpool game and both Tottenham games, I saw Chelsea as completely different at Tottenham than they played at Stamford Bridge.

"I don't know if the plan was like this, or they couldn't do it. With this quote, I presume the approach that Chelsea will have tomorrow.

"Every game is completely different, [our] performance was really good, minimising the Champions of Europe when all players were fit and there.

"It was really exceptional. In that moment we were below them, knowing the difficulties if we didn't get the points. Our commitment with and without the ball was exceptional.

"We won unfortunately with a small margin, we couldn't score much more. We had three one-on-one situations, but the victory was nice.

"[Saturday] will be completely different. We learned from that, like how we can be better especially in attack, [so] they will change, like their manager said, their approach. They know they need points to be still there [in the title race]."

The debate around coronavirus-enforced postponements reared its head again after Burnley had their game with Leicester City called off, but Guardiola – who confirmed his side have had more positive COVID-19 cases – did not want to get into it.

"It's a Premier League decision," he said. "I don't get involved. COVID is all around the world. The situation is there, in the next two or three months it will still be there, hopefully it will decrease step by step."

On City's cases, he added: "Some people are coming, some are positive again. When you test once, twice negative, then you come back, otherwise you stay at home.

"It happened in the last two-three months affecting all the clubs. We have some new cases, they want privacy so I can't say who."

Ralf Rangnick has told Dean Henderson and Donny van de Beek to sit tight and wait for their chances to come at Manchester United.

The United interim boss, who expects to have Cristiano Ronaldo and Harry Maguire back for Saturday's Premier League match at Aston Villa, knows Henderson and Van de Beek have been considering leaving Old Trafford.

Speaking in a news conference on Friday, Rangnick made the case that goalkeeper Henderson and midfielder Van de Beek can be useful assets for the Red Devils over the closing months of the season.

He described Henderson as a "fantastic" shot-stopper, but recognised he wanted Premier League game time that cannot be guaranteed at United. The Englishman has played just twice for United this term, neither appearance coming in the league.

Rangnick also knows Van de Beek is hungry for first-team football for the sake of his Netherlands career, with the World Cup coming up in Qatar at the end of the year.

Addressing Henderson's situation initially, Rangnick said: "I told him that I would like him to stay because he's a fantastic goalkeeper. In training yesterday, he had another couple of fantastic saves.

"I really like to have him on board, as one of three top goalkeepers. I can fully understand that he wants to play because he's in an age where, as a goalkeeper, he should regularly play.

"On the other hand, we are still in three competitions, we need the three goalkeepers we have right now. I told him that, but I can also, on the other hand, understand his desire to get game-time elsewhere in the Premier League."

David de Gea has reasserted himself as United's first choice between the posts, after Henderson played 13 Premier League games last season, while the other senior goalkeeper on United's books is third-choice Tom Heaton.

Henderson was not involved in the FA Cup clash with Villa on Monday, when United took a nervy 1-0 win in the third round. De Gea started that game and Heaton was the substitute goalkeeper, with Rangnick saying it was illness that kept Henderson out of the game.

Van de Beek came off the bench in the 72nd minute to strengthen a midfield that was being over-run.

The former Ajax man could be practically assured of regular involvement at another club, but at United he has been used just seven times in the Premier League this term. All those appearances have been as a substitute, with Van de Beek spending a meagre total of 68 minutes on the pitch.

"It's the same situation as it is with Dean," said Rangnick. "I'm glad to have him in the squad."

The former RB Leipzig boss said he spoke to Van de Beek after training two weeks ago.

"I told him I would advise him to stay until the end of the season. He wants to play in the World Cup for his country and [Netherlands coach] Louis van Gaal obviously told him that in order to be a regular starter for the World Cup, he needs to regularly play for his team," Rangnick said.

"I can understand his desire to play; on the other hand, we have a lot of competition in our squad in exactly those positions."

United were without Maguire and Ronaldo for the cup clash with Villa, so to have them back adds experience and quality at each end of the pitch, albeit with neither man having been at the height of his powers in recent weeks.

Across his career, Ronaldo has been involved in 11 goals in nine Premier League starts against Villa (eight goals, three assists). That is the most goals he has scored (eight) and been involved in (11) against a specific opponent in the competition.

Jadon Sancho and Phil Jones should also be up for selection after being absent for the FA Cup game.

"I think they will be available," Rangnick said of his quartet. "They only trained yesterday for the first time, Cristiano yesterday, Harry the day before yesterday.

"We have to wait for the final session this afternoon but as it seems right now, they should be available for tomorrow."

While the signs are positive there, United will be hampered by one-match suspensions for Luke Shaw and Scott McTominay that rule both out of the Villa Park game.

Villa have not won any of their last 22 home league games against United (D7 L15) since a 3-1 victory in August 1995. That ranks as the longest winless home run any side has had against another in English Football League and Premier League history, according to Opta.

However, Villa scored a 1-0 win at Old Trafford in September, with Bruno Fernandes missing a last-gasp penalty, and will be attempting to win consecutive league games against United for the first time since November 1976.

They last did the league double over the Red Devils in 1954-55. A United win would be their 300th away from home in the Premier League, making them the first side to reach that mark.

Jurgen Klopp insisted the thought of 350 games as Liverpool manager will not enter his mind when he reaches the landmark in the Reds' clash with Brentford.

Klopp has enjoyed huge success since taking over in 2015, reaching two Champions League finals and winning the tournament in 2019 before guiding Liverpool to their first Premier League title a year later.

However, Liverpool head into Sunday's clash with the Bees 11 points behind league leaders Manchester City and having been held to a 0-0 draw by Arsenal in the first leg of their EFL Cup semi-final.

Asked about the prospect of reaching game 350, Klopp told a pre-match media conference: "I'm really happy and proud of the things we have achieved here so far, but I don't think a second about it.

"It's just the next game is really decisive when you are manager at this club. In all competitions, everybody, ourselves involved, expects to win the next game and that's the task.

"But it's fine, we have a great squad, great players and I'm really happy about the time we had here so far and hope to enjoy the next few years.

"These numbers are not important to me, but 350 is a nice one, better than 15 and out."

Winless in their last three Premier League games and without star forwards Mohamed Salah and Sadio Mane as they compete in the Africa Cup of Nations, Liverpool saw Virgil van Dijk, Andrew Robertson and James Milner sustain knocks against Arsenal.

However, all three are available to face a Brentford team who held Liverpool to a 3-3 draw in the reverse fixture in London in September.

"As far as I know, no new real injuries," Klopp added. "Knocks last night, Virg, Robbo, Milly, but directly after the game, medical team said all are fine.

"We will see. No 'injuries' so far."

The cup tie with the 10-man Gunners saw Liverpool rack up 78.1 per cent possession and 17 attempts to Arsenal's three, but only one of those efforts hit the target.

Speaking about the absence of Salah and Mane, as well as midfielder Naby Keita, in the aftermath of that stalemate, Klopp said: "Any team would miss Salah, Mane and Keita.

"Could we be prepared for it? I don't think so.

"We've known that already for years. This team was what we had tonight, it can play and score, definitely."

Ole Gunnar Solskjaer came in for just a smattering of criticism during his final weeks in charge of Manchester United. The fact that his team had apparently forgotten how to play professional football matches was quite the talking point.

But few things put quite so many noses out of joint as his comments about Marcus Rashford some weeks before his departure.

In October, as Rashford prepared to make his first appearance since shoulder surgery two months earlier, Solskjaer suggested the forward needed to "maybe prioritise his football" after 18 months of dominating headlines for philanthropy rather than finishing.

Later, Solskjaer was forced to clarify his remarks as some felt he was criticising Rashford for tallying up free school meals instead of goals. That felt unfair given Solskjaer was generally speaking in glowing terms, but if there was a hint of brutal honesty there, it's only grown more pertinent.

Rashford is an estimable young man, one who has forced a government into two U-turns over providing for disadvantaged children, who was awarded an MBE for his charity work at the age of just 24. He is also an elite footballer who has produced far too many uninspiring performances in the past year, whose form only seems to be getting worse, who has only played a full game on two occasions all season and who caused astonishment in the Stretford End when he gave up chasing a loose ball in the penalty area in the FA Cup win over Aston Villa.

For United interim manager Ralf Rangnick, Rashford is potentially one of his greatest assets. Right now, his form – and his mood – represent one of his biggest problems.

Rash-flow problems

Rashford started 2021 in promising fashion, with six goals and five assists in 20 starts in all competitions beginning with one of each in an FA Cup win over Liverpool at Old Trafford. Soon came a seven-game run in which United went into pragmatic mode, keeping clean sheets in all but one match but scoring only four times. Rashford then netted in consecutive games and looked to be firing again.

He would only score another four goals for United all year.

Some important context is needed. Rashford went through some personal upheaval last year that would have been hard simply to shrug off. He also spent much of 2021 playing through injury: ankle and shoulder problems were a big hindrance when he was on the pitch, and the latter required an operation following Euro 2020, a tournament to which even he admitted he probably shouldn't have gone. He did go, of course: he played 83 minutes, all as a substitute, failed to score and missed a penalty in the final shoot-out. He did not then appear in 2021-22 until October 16; he marked his return with a goal, but it came in a 4-2 defeat to Leicester City that spelled the beginning of the end for his manager. This was hardly the smoothest of years.

Part of the reason Rashford played through pain for so long was he embraced being Solskjaer's Mr Reliable. He played 135 games under the Norwegian, more than any other United player. In that time, he also scored the most goals – 55, 11 more than Bruno Fernandes – and provided 22 assists, a tally behind just Fernandes (33) and Paul Pogba (23). In the nearly three years Solskjaer was in charge, both as caretaker and permanent boss, only seven Premier League players scored more goals than Rashford in all competitions.

Like many managers, Solskjaer had his favourites. It gave his team a consistent structure and meant that, when things were going well, good habits and good spirits could permeate the side. But when it started to go wrong, when players kept their places even as their form took a nosedive, the scrutiny and pressure to improve grew exponentially. This took its toll in real time: Harry Maguire went from England rock to a running joke; Fernandes looked more forlorn with every flail of his arms. And Rashford, as former United star Rio Ferdinand pointed out, has looked like he has the weight of the world on his shoulders, running himself further into the ground with every insipid display.

From April 9 until the end of 2021, Rashford scored four goals in 23 games in all competitions. Among Premier League players, he had a worse strike rate than Burnley's Jay Rodriguez (five goals in 23 games) and Leicester defender Jonny Evans (four in 21). Former Red Devil Danny Welbeck scored the same number in just 14 Brighton and Hove Albion appearances.

Over the same time frame, Rashford managed three assists, as many as Pierre-Emile Hojbjerg and Joshua King, and one less than Conor Gallagher. That left him on seven direct goal involvements, while midfielders John McGinn and Declan Rice managed eight. Rashford created 19 goalscoring chances, marginally more than Leicester's close-season signing Patson Daka (18) and Chelsea centre-back Antonio Rudiger (17). Rashford (45) had only two more shots than Rudiger over that time, with just 14 on target, the same number as Liverpool right-back Trent Alexander-Arnold.

On average, Rashford was involved in 0.41 goals per 90 minutes; among United players with at least two goals in that time, only three come off worse. One is July signing Jadon Sancho, a 21-year-old trying to adapt to a new club, new systems and new expectations. The others are Fred and Scott McTominay.

Running for Ralf

Just after his appointment, Rashford spoke positively about Rangnick's attention to detail.

"He's done a good job because prior to him coming in he spent a lot of time analysing the team and analysing individuals and he knows what our strengths are," he said to Sky Sports.

"We've got a lot more together, we've obviously been working on pressing and we'll still improve on that, but the main thing is just doing everything together as a team, whether we are attacking or defending."

For his part, Rangnick doesn't appear outwardly worried about Rashford's form, even though he was at a loss to explain it. Speaking after the win over Villa, he said: "Of course it would be good, for example, for Marcus if he could score a goal but as long as he's trying, as long as he's training well, I don't see that much of a problem."

"Trying" doesn't seem to be an issue. Rangnick, we know, is a stickler for hard running and high pressing, and only Cristiano Ronaldo (93) has made more sprints than Rashford (85) in the Premier League since the German was appointed in late November (including the 3-2 win over Arsenal, when Michael Carrick was still in caretaker charge of the side). Similarly, only McTominay (82) has contested more duels than Rashford (53), and nobody has attempted more dribbles (22). 

Going back to the start of last year, Rashford has recorded 500 sprints in the Premier League, the fourth-most among United players at a rate of about one every four and a half minutes. The only United attackers to play at least 10 times with better rates are Sancho (4.35) and Dan James (3.11), now at Leeds United. Ronaldo, if you're interested – and let's face it, you are – averages roughly one sprint every five and three-quarter minutes, which is more frequent than Fernandes, who is closer to one every six minutes.

On and off the pitch, you can't fault Rashford's endeavour. The story of the past year hasn't been one of attitude, but aptitude. Rashford runs, but not always at the right moments; he dribbles, but in the wrong areas; he finds an opening, and he makes the wrong choice.

Rash converters

You don't need to look too closely to see that Rashford's output is below par this season, but the deeper you dig, the starker that reality becomes.

His career average for minutes per goal is 207; this season, it's 282. His dribble success rate is 38.6, down from 42.5 on average. His shooting accuracy is 53.3, down from 57 on average. His crossing accuracy has more than halved from 15.8 to 7.1.

Across all competitions since January 1 last year, Rashford has attempted 207 take-ons, way more than any other United player (Mason Greenwood is next on 170), 178 of which have been in the opposition's half. His 21 drives into the box are at least 10 more than anyone else at United, he is joint-top for take-ons with a shot (seven, with Greenwood) and top for take-ons with a chance created (four). He is also United's attacking player with the most progressive carries in which he has moved with the ball 10 metres or more towards the opponents' goal (158). However much the Villa incident suggested otherwise, there's no obvious lack of effort.

Yet there is a verifiable, worrying lack of efficacy in these attempts to make things happen. Looking at the Premier League alone, only five players since last January 1 have attempted more take-ons in the opposition half than Rashford (128); the man top of that list, Adama Traore (184), is the only player with more drives into the box (26 to Rashford's 16). But the Wolves winger, so often derided for end product, has 11 take-ons with a shot and 14 take-ons with a chance created, 14 more than Rashford when you combine the two.

Over the same period, Mohamed Salah (41) had the most carries to end in a shot, with Greenwood second alongside Harry Kane with 38. There are 25 players who had more than Rashford (18). When it comes to a carry ending in a chance created, Traore is top of the table with 36; Rashford, with 10, is below 49 other players.

It reflects a recurring concern: that when Rashford runs at defenders with the ball, it's less a calculated attacking move and more one of hope, or desperation. It's a symptom of both Solskjaer's system, which relied on the spontaneity of the individual, and of Rashford's own conviction that any problem is just waiting for him to solve it. He tries to play like a man who has earned the famous United number 10, a superstar performer in a squad bursting with talent. In reality, the shirt looks heavier with every passing minute.

In some ways, Rashford is emblematic of United's wider problems. He desperately needs not only a morale boost, but a tactical one: he needs hardline instructions, and to play in a system in which he feels confident as well as competent. Ironically, he is one of the few for whom the Solskjaer-Rangnick transition should be simplest since both Ole's 4-2-3-1 and Ralf's 4-2-2-2 offer the kind of wide left attacking role Rashford likes best.

Whatever the root cause of his malaise, he will be desperate for things to change, and change quickly. Perhaps they will. Perhaps he'll light up Villa Park on Saturday, kick-start his return to form and United's road to redemption.

After all, U-turns are a Marcus Rashford speciality.

Novak Djokovic's Australian Open fate is set to be determined in a fresh hearing on Sunday – with the defending champion back into detention before that takes place.

In a crushing blow to his preparations for the grand slam, Djokovic learned on Friday that his visa had been revoked for a second time, meaning he faces the prospect of deportation.

The 34-year-old is fighting the decision, and lawyer Nick Wood, on behalf of Djokovic, contended in a directions hearing on Friday evening that the "underlying new rationale" behind the Australian government's latest move to kick out the Serbian is that it contends his presence "will excite anti-vax sentiment".

Wood said immigration minister Alex Hawke had given no consideration to the impact that deporting Djokovic may have among those opposed to COVID-19 vaccines, saying his client was of "negligible risk", "of good standing" and had a medical contraindication to a vaccine.

In a statement released on Friday, Hawke said the decision had been taken "on health and good order grounds, on the basis that it was in the public interest to do so".

Djokovic has expressed opposition to vaccine mandates in the past and has confirmed he has not been vaccinated.

For Djokovic, Wood said: "The minister only considers the potential for exciting anti-vax sentiment in the event that he's present, but the binary alternative of forcibly removing this high profile, legally compliant, negligible risk, medical contraindication player, precluding or impairing his ability to come back to Australia for three years and prejudicing his career, on the basis of two statements made in 2020 and the possible perception of those statements by others; the minister gives no consideration whatsoever to what effect that may have on anti-vax sentiment and indeed on public order. That seems patently irrational."

The case has been transferred from the Federal Circuit Court to the Federal Court of Australia, judge Anthony Kelly said, and will take place via videolink.

An initial hearing will take place with justice David O'Callaghan from the Federal Court on Saturday at 10:15 local time (Friday 23:15 GMT), it was announced.

Whatever happens now, this is woeful preparation for Djokovic ahead of the tournament where he was planning to mount an assault on a 10th Australian Open title, and a record-setting 21st grand slam.

He was cleared to spend Friday night at his current accommodation, rather than be moved immediately back into detention, but that is set to occur on Saturday morning at 08:00 local time in Melbourne when he reports for an interview with immigration officials.

Djokovic will then be allowed to attend meetings with his solicitors in person from 10:00 to 14:00 on Saturday, accompanied by Border Force officials, before returning to a detention hotel until he is reunited with his solicitors from 09:00 on Sunday.

To avoid possible disorder on the streets, he is set to meet his legal team away from their Melbourne offices, where fans gathered and unruly behaviour took place following Djokovic's first effort to clear a path to play at the tournament that begins on Monday.

Djokovic will for now be unable to practise at Melbourne Park. His opening match in the Australian Open is due to be scheduled for Monday or Tuesday.

Hawke explained why the visa had been revoked earlier on Friday, saying in a statement: "In making this decision, I carefully considered information provided by the Department of Home Affairs, the Australian Border Force and Mr Djokovic.

"The [Scott] Morrison government is firmly committed to protecting Australia's borders, particularly in relation to the COVID-19 pandemic."

Concerns have been expressed over the 34-year-old Djokovic's whereabouts prior to arriving in the country. Djokovic admitted there was a false declaration on his travel form to enter Australia, after it stated he had not travelled in the two weeks before arriving in the country.

The tennis star, who was seen in Spain earlier this month, put that down to "human error" and accepted breaching isolation rules in December after testing positive for COVID-19.

Thomas Tuchel believes Chelsea cannot hope to compete in a title battle with Manchester City when they are deprived of key players.

The Blues boss said Chelsea would have to "over-perform" to be in the Premier League trophy hunt, although he claims Pep Guardiola's City side are beatable in any one-off game.

Chelsea travel to face City at the Etihad Stadium on Saturday, and defeat would see the European champions fall 13 points behind the leaders with 16 games remaining.

Tuchel has seen centre-back Andreas Christensen ruled out of the game after testing positive for COVID-19, and such cases, along with a string of recent injuries, have significantly weakened Chelsea.

Pointing to City's strong record of keeping players available, Tuchel said that "maybe it's luck or they do it better".

Chelsea have elected to recall Kenedy from a loan spell at Flamengo to bolster their resources, and Tuchel said he could offer a solution at left wing-back, with Ben Chilwell sidelined.

City simply have strong options in every department, and Tuchel said: "They are the benchmark, they are the best team in England right now. This is something we have to admit realistically.

"We don't think a lot in the scenarios of 'what happens if?'. Let's play the game. I'm always in for a good fight, but I'm also very realistic. We are always up for a good fight with Man City and always there to push them to the limit and ask them questions they maybe don't like to answer.

"But they're very strong, very consistent, and perform on the absolute highest level.

"They opened the gap not over the last month, but they opened the gap over the last years. We will come up with a plan and push and help and support in the best way with genuine belief, but a team is a different team if everybody is available."

Reece James, Chelsea's attacking right wing-back, is, like Chilwell, out for the long term, and the England duo have been sorely missed.

To lose Christensen is another major blow, and Tuchel said it made Chelsea's task "even tougher".

"But does that make it impossible? No," he added. "For 90 minutes you can do anything, you can be brave, play with courage. You need a bit of luck."

Tuchel said Chelsea took the "wrong approach" in their previous game with City this season, saying they were "too passive and too defensive" when losing 1-0 at Stamford Bridge in September, declaring it was a "lesson learned".

"We have a good squad with a fantastic mentality," Tuchel said. "We need a bit more of a fight to bring out the extra edges.

"It's not enough to find even 100 per cent; we need to over-perform to catch City to be on top of the Premier League. To over-perform, you need simply everybody."

Australia's Travis Head struck a century to punish England on a rain-affected opening day of the fifth and final Ashes Test at the Bellerive Oval in Hobart.

The hosts, who have an unassailable 3-0 lead, finished Friday on 241-6 having earlier been reduced to 12-3 by an England side who won the toss and chose to bowl first.

England showed five changes from last week's drawn fourth Test in Sydney, including a debut for Sam Billings, and started in an impressive manner.

David Warner (0), Usman Khawaja (6) and Steve Smith (0) all went by the start of the 10th over, while Marnus Labuschagne would have followed had Zak Crawley not fumbled.

That may well prove a decisive moment in the final Test as Labuschagne and Head launched a counter-attack by scoring 53 runs from the next seven overs.

But on 71 from 72 balls, Labuschagne comically wrong-footed himself when attacking a Stuart Broad delivery and could only watch from the floor as Australia lost another wicket.

England lost bowler Ollie Robinson to injury and their problems were compounded by the work of Head, who continued to rack up the runs when joined by Cameron Green.

Head survived a big scare on his way to reaching 101 from 113 balls, but his day was ended after he chipped a Chris Woakes delivery to Robinson at mid-on.

Green got to 74 before holing out at deep mid-wicket and only nine more balls were bowled due to rain, with Mitch Starc (0) and Alex Carey (10) to resume play on Saturday.

Travis keeps his Head after Crawley loses his

England could not have asked for a much better start on the green surface, with Robinson and Broad dismantling Australia's top order by dismissing Warner and Smith for ducks.

But Crawley's drop of Labuschagne, combined with England's wayward bowling from that point on, allowed Head – recently sidelined due to COVID-19 isolation – to grab the fifth Test by the scruff of the neck.

He went past the 100 mark, becoming the seventh Australian to do so in a day/night men's Test innings after Warner, Labuschagne, Khawaja, Smith, Shaun Marsh and Peter Handscomb.

Green shoots of recovery

Australia all-rounder Green had a maiden hundred in his sights, only to fall to Mark Wood's short-ball trap 16 runs shot of three figures.

At 22 years and 225 days, he is the youngest player to score 50 or more runs in a men's Test innings for Australia at Bellerive Oval and the fourth youngest overall at the ground.

Philosophical differences were behind the Houston Texans' decision to part with head coach David Culley after one season with the team, according to general manager Nick Caserio.

The Texans ended a disappointing campaign 4-13, and offensive coordinator Tim Kelly has also departed after eight years with the franchise, which finished third in the AFC South for a second consecutive season.

The Texans ended their season with a 28-25 loss to the Tennessee Titans, leading a late fightback against their rivals after finding themselves 21-0 down at the halfway point.

Caserio, who has been in the GM post for just a year, released a statement explaining the decision to relieve both Culley and Kelly of their duties, with the Texans ending the season ranked last in the NFL for total offense, and Culley having reportedly resisted attempts to make changes to his offensive staff. 

"Earlier today, I met with David Culley and Tim Kelly to inform them we will be moving in a different direction with the head coach and offensive coordinator positions," the statement read. "I came to this difficult but necessary decision after reviewing our football operations.

"While a change after one season is unusual, we had philosophical differences over the long-term direction and vision for our program moving forward. 

"We appreciate coach Culley for helping us navigate through a difficult season, but it is my responsibility to make decisions that I feel are best for our organisation.

"The search for the next coach of the Houston Texans will begin immediately."

Barbora Krejcikova saved seven match points on her way to beating Anett Kontaveit in a thrilling Sydney Tennis Classic semi-final on Friday.

The world number four prevailed 0-6 6-4 7-6 (14-12) in a match that went the distance and will take on Paula Badosa, who beat in-form Daria Kasatkina in the other semi-final.

Krejcikova had lost five in a row against top-10 players and was soundly beaten in the first set, but she held in the second and earned the only break in the ninth game to level up. 

That set up an incredible decider, which fourth seed Kontaveit led 6-5, but she could not take the first three of her match points as Krejcikova battled valiantly to force a tie-break.

Krejcikova felt her opponent's pain as she then squandered two match points of her own when leading 6-4. 

It appeared neither player wanted to win as two more match points went begging for Krejcikova and four for Kontaveit in what turned into a real classic.

But Krejcikova eventually took her fifth opportunity to see off Kontaveit and reach a sixth WTA singles final.

"I think from both sides it was a really, really tough match," Krejcikova said. "I think we played wonderful tennis. 

"It was very, very tight, and I'm really happy that I was able to hold the nerves better and that I won this match.

"I was just playing, just trying to fight for every single ball. When I had those match points down, I was just trying to figure out how to build up the point and how to win the point."

Badosa awaits Krejcikova in Saturday's final after beating Kasatkina in a match with far fewer twists and turns.

Competing in her second semi-final in as many weeks, it was similar disappointment for Kasatkina as she fell to a 6-2 6-2 loss.

French Open quarter-finalist Badosa hit 26 winners to Kasatkina's 12 and did not look back after winning 14 of the opening 16 points.

At the Adelaide International 2, meanwhile, it will be an all-American final as Madison Keys and Alison Riske advanced past Tamara Zidansek and Coco Gauff respectively.

Riske was given a walkover win against Zidansek, who withdrew with an abdominal injury, while Keys beat compatriot Gauff in three sets.

Real Madrid defender Dani Carvajal will miss the Supercopa de Espana final against Athletic Bilbao in Riyadh on Sunday after testing positive for coronavirus.

Carvajal started the 3-2 semi-final win over fierce rivals Barcelona at King Fahd Stadium, but will not feature in the showpiece at the same venue this weekend.

The LaLiga leaders revealed on Friday that the Spain international had returned a positive COVID-19 test.

Lucas Vazquez replaced Carvajal at the end of normal time in the victory over Barca, which was secured courtesy of Federico Valverde's extra-time strike.

Holders Athletic came from behind to beat Atletico Madrid 2-1 in the second semi-final on Thursday.
