Red Bull chief technical officer Adrian Newey is expecting a "tough year" in the 2023 Formula One season due to punishments issued for the team's budget cap breach.

The constructors' championship winners were handed a $7million fine by the FIA and a reduction of aerodynamic testing time in the wind tunnel, which Newey says will cost the team.

Another dominant year for Red Bull is therefore unexpected, with the punishment opening the door to Ferrari and Mercedes to dethrone two-time drivers' champion Max Verstappen.

Newey has conceded that the team are set for a difficult period in the 2023 season, particularly with regulation changes that will result in "significant aerodynamic change".

"There's no testing, it's very difficult to put an answer to say that [the punishment] will cost us so many tenths of a second per lap," he said.

"But the reduction of internal testing means we can therefore evaluate less, less different components, less different ideas.

"If we're really smart and always puts on the right things on the model, then it doesn't make much difference. But that's not how it works; there are always some parts that you hope will work and don't and vice versa.

"So, it's difficult and it's a restriction for sure that will affect us.

"I think then there's a regulation, a small regulation change over the winter, which is lifting of the floor edge by 50 millimetres, which of course, sounds tiny, but in reality, it's quite a significant aerodynamic change.

"So, like all teams were working to reduce the deficit from that in addition to the normal development that goes on from year to year, I think we've obviously had a good year, particularly in the second half of the season. We do have the best car.

"But Ferrari won't be resting, and they will be kind of sorting out where the weak areas that they had a couple of reliability problems with, and they made a couple of pit wall mistakes. So, they'll be right back.

"And then, of course, Mercedes. They were quite a long way off the pace and evolving. But then they won the last race but one, so we know they will be right there. It's going to be a tough year for sure."

The 2023 Formula One season begins in Bahrain in March, with a record-breaking 24 races scheduled across the year.

Fikayo Tomori is aware "I have to do more" to avoid a repeat of the "disappointment" at being left out of England's World Cup squad.

Despite playing every match for Milan in Serie A this season, while missing just one of their six Champions League games through suspension, the defender was not included by Gareth Southgate, whose side were eliminated by France in the quarter-finals.

Tomori also played a key role as the Rossoneri last term, featuring 31 times as they ended their 11-year wait to claim the Scudetto, pipping rivals Inter to the title on the final day of the campaign.

But having only earned three senior England caps since making his debut against Kosovo in November 2019, the 24-year-old feels he must raise his game to force himself back into contention for the European Championship in 18 months' time, should the Three Lions qualify.

"I'm always motivated, obviously there is disappointment because I wanted to be there," he told DAZN. "But it didn't happen, and I know I have to do more to go to Euro 2024.

"There was disappointment, but I have to keep working and then let's see. Right now, I'm happy and content."

Tomori and Milan resume their Serie A title defence when they travel to Salernitana on January 4. Stefano Pioli's side are second after 15 matches, but already trailing unbeaten leaders Napoli by eight points.

The centre-half admits the reigning champions have had to adapt to different challenges from their opponents this season, but he is confident the campaign can culminate in a successful title defence.

"In my opinion, the most difficult thing is to win again," he added. "Last year, we know that there weren't many people who thought we could win. But now we have done it, and we have the Scudetto on our chest, whoever plays against us changes.

"So, we have to look for another way to win and another level - both in mentality and in play. We knew it would be difficult, but we can win again, and we will do everything for that."

Marc Cucurella says Chelsea's players will work to implement Graham Potter's ideas when the season restarts, backing the former Brighton and Hove Albion boss to succeed at Stamford Bridge.

The pair arrived at the club a month apart, with the Spaniard sold to the Blues before his coach followed him from the Amex Stadium following Thomas Tuchel's dismissal.

With only seven wins from his first 14 games, Potter is yet to deliver the turnaround in fortunes new owner Todd Boehly was likely hoping for, with the club eight points off the top four.

But Cucurella is confident they will make strides under the Englishman, tipping them to improve over the remainder of the campaign.

"We need to work and understand his ideas and the results will arrive," he told The Sun. "It is difficult because it is a new coach with different ideas.

"It is difficult to change without the time to train. This part of the season we have time, we meet more and know the ideas of the coach. This second part of the season, I am excited for."

Though several members of Chelsea's squad have been away on World Cup duty since mid-November, the Blues have continued to train, including a warm-weather camp in Abu Dhabi.

Cucurella, one of those who has remained with the club, says he has valued the chance to reconnect with Potter, and that the team are viewing the restart as a fresh campaign.

"This is maybe another season," he added. "It is good for us. The last games before the break, we didn't play too good or get results, but this is a new season.

"These weeks gave us time for training to prepare for the second half of the season. It is good training together because you understand the players.

"All the changes are difficult. We have a lot of players to come with a new manager, [and] not a lot of training time because we play a lot of games.

"We need to know his ideas and then play together. These weeks have been very good for us."

Chelsea's first game back will see them welcome Bournemouth on December 27.

LIV Golf has added three new events to the circuit's 2023 schedule, which will take place in Arizona, Oklahoma and West Virginia.

Last month, the controversial Saudi Arabia-backed tour announced stops in Mexico, Spain, Singapore and Australia would be included on the calendar next year.

Wednesday's addition of three competitions to take place in the United States means LIV Golf has now revealed half of its 14 planned events for 2023.

A statement from the circuit said: "LIV Golf today announced three new championship venues that will host tournaments as part of the 2023 LIV Golf League schedule. 

"The Gallery Golf Club in Tucson, Arizona (March 17-19), Cedar Ridge Country Club in Tulsa, Oklahoma (May 12-14), and The Greenbrier in the Allegheny Mountains of West Virginia (August 4-6) will welcome many of the sport's biggest stars in the groundbreaking LIV Golf League teeing off in 2023."

LIV Golf chief executive and commissioner Greg Norman added: "LIV Golf's expansion to new US markets adds to the growing excitement for the league launch in 2023. 

"More fans across the country and around the globe will experience the LIV Golf energy and innovative competition that has reinvigorated the sport.

"These championship courses will contribute to the transformative season ahead for players, fans and the game of golf."

LIV added that final rosters for the rebranded LIV Golf League will be announced in 2023, with 12 team franchises set to compete across 14 events for a total of $405million in prize purses.

Grant Wahl died after an undetected aortic aneurysm ruptured, the American journalist's wife Dr. Celine Gounder has revealed.

The 49-year-old collapsed in his seat while reporting on last Friday's World Cup quarter-final between Argentina and the Netherlands at Lusail Stadium.

Wahl was attended by medics inside the ground and taken to hospital, but his death was later announced and an outpouring of tributes soon followed.

He was flown back to New York City on Monday, and an autopsy revealed the cause of his death, with wife Gounder ruling out any sort of foul play.

"Grant died from the rupture of a slowly growing, undetected ascending aortic aneurysm with hemopericardium," Gounder posted on her husband's blog. 

"The chest pressure he experienced shortly before his death may have represented the initial symptoms. No amount of CPR or shocks would have saved him. 

"His death was unrelated to COVID. His death was unrelated to vaccination status. There was nothing nefarious about his death."

Wahl, who was best known for his long career with Sports Illustrated, attended a medical clinic at Qatar 2022's Main Media Centre four days prior to his death after feeling unwell and was diagnosed with bronchitis.

The much-respected reporter was at the centre of controversy earlier in the World Cup when he sported a rainbow t-shirt in support of LGBT rights as he attempted to attend a match.

He was initially prevented from entering Ahmad bin Ali Stadium for the United States' group game against Wales, although he was later allowed inside.

Wahl's brother suggested he had been "killed" in the immediate aftermath of his death, but he later said he "regretted" those comments and no longer believed that to be true ahead of Wednesday's announcement.

Paying her own respects to her husband, Gounder said: "We will forever cherish the gift of his life; to share his company was our greatest love and source of joy.

"Grant was an incredibly empathetic, dedicated and loving husband, brother, uncle and son, who was our greatest team-mate and fan. 

"While the world knew Grant as a great journalist, we knew him as a man who approached the world with openness and love."

A World Cup security guard has died following a serious fall at Lusail Stadium during last Friday's quarter-final between Argentina and the Netherlands.

John Njau Kibue received emergency treatment inside the ground and was taken to a nearby hospital, where he passed away in intensive care on Tuesday.

The Qatar Supreme Committee confirmed Kibue's passing in a statement on Wednesday and announced an investigation will be held into the circumstances leading to his death.

"We send our sincere condolences to his family, colleagues and friends during this difficult time," the statement read.

"Organisers are investigating the circumstances leading to the fall as a matter of urgency and will provide further information pending the outcome of the investigation. 

"We will also ensure that his family receive all outstanding dues and monies owed."

Kibue is the second known migrant worker to have died since the tournament began, following the death of a Filipino man in the group stage at a resort used by Saudi Arabia.

Speaking last week, Qatar 2022 chief executive Nasser Al Khater said "death is a natural part of life" when he was questioned over the passing of the migrant worker.

The Lusail Stadium is to host Sunday's final between Argentina and either France or Morocco, who face off in the second semi-final on Wednesday.

Former world number one Jason Day will not be making an imminent defection to LIV Golf, but has not ruled out departing the PGA Tour in the future if his view changes.

The Australian, who won the 2015 PGA Championship for his only career major to date, is close friends with countryman Cameron Smith, who made the switch after winning The Open Championship earlier this year.

With several of the sport's leading stars having defected to the Saudi Arabia-backed breakaway, a bitter civil war has been sparked between the two tours.

While stating he would not follow Smith to the Greg Norman-headed competition immediately, Day refused to completely chalk off a switch down the line, while adding he remains saddened by the split.

"I definitely would say no, I wouldn't go as of now," he told the Palm Beach Post.

"[But] who knows in a year's time, you might think differently.

"I don't blame some of the guys for going because there's quite a lot of money these guys are earning. I understand it.

"For me, it just depends on how you feel about major championships. I know that's all up in the air right now if they're going to play or not, and they don't have world ranking points out there.

"It's disappointing there's a divide on both sides. All those guys out there are my friends.

"Some of the friendships fractured between some of the guys who have been more outspoken [but] I don't mind the guys leaving."

Day suggested a potential way to harmony would be to stage the PGA Tour from January through August, and then have the LIV competition follow to complete the year.

"I honestly wish the tours could join somehow," he added. "That would be great. I think that could potentially work if you want to do it. That would be fun."

The prospect of England appointing a foreign manager if Gareth Southgate leaves the role is "unacceptable", according to his predecessor Sam Allardyce. 

Southgate's future as England manager is uncertain following the Three Lions' 2-1 World Cup quarter-final loss against France.

He remains under contact until the end of Euro 2024 but has indicated he will make a decision on his future after Christmas.

The likes of Mauricio Pochettino and Thomas Tuchel have been touted as potential replacements if Southgate does depart, but Allardyce is against the appointment of a non-British coach.

"It can't happen, not again. There are enough qualified British managers in this country to pick the right man," Allardyce, who led England for one game in 2016, told Sky Sports.

"I just don't see it. I think it would be a massive knock-back for our country, and a massive knock-back for young managers trying to make their way.

"It's hard enough to get in the Premier League as a British manager, but to think that it's taken away from you to become the national team's coach… I think it's unacceptable, personally."

Fellow former England boss Fabio Capello said Southgate should stay on if he has the full support of the squad on Tuesday, and while Allardyce concurs, he would understand if Southgate opted to step down.

"How long do you want to put up with that scrutiny and that pressure? Lots of managers will leave their positions at the end of the World Cup," Allardyce said.

"While it's an experience and a job you could never turn down, not in my opinion anyway, there's a time when you have gone through the mill enough.

"I think this squad is good enough for him to think: 'I need to carry on because I think we could win the Euros'.

"But there is the other side of it to consider: 'how much more pressure do I want to continue to cope with, and is it time for me to bow out?'"

England's hopes of reaching the final four were dashed when Harry Kane blazed an 84th-minute penalty over the crossbar, having converted from the spot earlier in the second half.

Allardyce does not believe the presence of Kane's Tottenham team-mate Hugo Lloris in the France goal impacted his miss, putting it down to the pressure of the moment. 

"I don't get any of that rubbish about Lloris sussing him out because they play for the same club. It was the pure pressure of the event," he added.

"He strikes a penalty so well normally, and if he struck it as well as he did the first one, Lloris would have had no chance.

"I always said from the start that we had the strongest squad in this World Cup, and I still believe that. The biggest regret is that this competition only arrives once every four years."

Paulo Bento has thanked South Korea's players for providing him with "one of the most beautiful experiences" of his life in their run to the knockout stage of Qatar 2022.

South Korea pulled off a late 2-1 win over Portugal in their final group game to reach the last 16, where they were heavily beaten 4-1 by Brazil.

Bento, appointed in 2018 as Shin Tae-yong's successor, announced immediately after that match he would not be renewing his contract with South Korea.

The Portuguese coach said a final farewell to supporters on Tuesday before flying back to his homeland.

"I am thankful to all the players, due to their professionalism, work ethic and their behaviour," Bento said.

"They gave me the opportunity to have one of the most beautiful experiences of my life, which I will never forget.

"Personally I have no words to thank you all for the respect, affection and support you showed during this amazing experience."

South Korea also drew 0-0 with Uruguay and lost 3-2 to Ghana in Group H, with their win over Portugal enough to see them through on goals scored.

It was the first time since 2010 that the Asian nation had made it past the first hurdle, though they were outclassed by Brazil in a one-sided last-16 tie.

The Taegeuk Warriors intend to name Bento's successor by February ahead of the next international break the following month.

Chelsea forward Armando Broja is expected to miss the rest of the season after rupturing the anterior cruciate ligament in his right knee during a friendly against Aston Villa on Sunday.

Broja, who spent the 2021-22 season on loan at Southampton, has made 18 appearances for Chelsea this term, scoring his first Blues goal in October's Premier League win over Wolves.

The Albania international was chosen to lead the line against Villa in Abu Dhabi, with Graham Potter looking to get his squad up to full speed ahead of the Premier League's resumption later this month.

However, Broja was carried from the field after going down clutching his left knee, having fallen awkwardly when appearing to catch his studs in the turf.

A Blues statement read: "Having sustained a knee injury during the first half of Sunday’s friendly against Aston Villa, Armando underwent further assessment following the club’s return to England.

"Scan results from those assessments have unfortunately confirmed an anterior cruciate ligament rupture and that surgery will be required.

"Following the operation, Armando will work closely with the club’s medical department during his rehabilitation and is expected to miss the remainder of the 2022-23 campaign."

A youthful Chelsea side fell to a 1-0 defeat against Unai Emery's men, with John McGinn sweeping home the only goal of the game after seven minutes.

Chelsea will resume their Premier League campaign against Bournemouth on December 27 at Stamford Bridge, having dropped to eighth in the table following a poor run ahead of the World Cup.

Radja Nainggolan has accused former Roma sporting director Monchi of ruining the club, laying the blame for their struggles at his feet.

The Spaniard, who is now back with former club Sevilla, arrived at Stadio Olimpico in 2017, amid a period where the club were frequent rivals to Juventus in the Serie A title race.

Although they finished third in his first season, an exodus of key players – including Nainggolan, and now-Liverpool duo Mohamed Salah and Alisson – saw them finish sixth in 2018-19.

The club have struggled to recover their top-four status since, even after Monchi's own exit in 2019, and Nainggolan has suggested it was the Spaniard's calls that sunk their once-promising credentials.

"He ruined the team," he told Tradizione Romanista. "He sold all the players. I can't even name him. If I'd known he was leaving soon after I went, I would have stayed.

"We had very strong players, and then we sold them. If you want to win, you have to keep strong players. If you always change, you will never have a solid base to work off."

At 34, Nainggolan shows no sign of slowing down, but the midfielder says a return to Roma will not be on the cards if he looks to depart Antwerp.

"If I went back to Roma now, I would run the risk of ruining all of the wonderful memories I have there," he added.

"Roma was the place, in terms of football, where I felt loved and respected. I'm too old to go back now. I live for football in my own way."

Cheteshwar Pujara and Shreyas Iyer steered India to an opening-day recovery against Bangladesh in the first Test in Chattogram.

The tourists won the toss at Zohur Ahmed Chowdhury Stadium and opted to bat first, with opener KL Rahul deputising as captain in place of the injured Rohit Sharma.

Impressive knocks from Pujara (90) and Iyer (82 not out) helped them steadily build a total they hope will offer a defence against their hosts, ending the day on 278-6.

But sturdy figures from Taijul Islam (3-84) and Mehidy Hasan Miraz (2-71) helped Bangladesh keep their opponents on something of a leash.

The early momentum appeared to favour them, with a three-wicket flurry taking Shubman Gill, Rahul and Virat Kohli - the latter for a solitary single - at the cost of just seven runs as India were swiftly reduced to 48-3.

A hard-hitting cameo from Rishabh Pant, with 46 off 45 balls and eight boundaries to boot, saw India wrestle back control.

When he fell to make it 112-4, Iyer - in just his sixth Test match - joined Pujara at the crease to mount a controlled partnership, putting together 149 for the fifth wicket.

It was Bangladesh who served up the final sting of the game however, following the latter's dismissal, with Axar Patel trapped lbw off the final ball of the day to keep this encounter hanging in the balance.

Iyer showcases middle-order strength

Having nabbed a century on debut against New Zealand last year, the India batter has posted another four half-centuries since at the Test crease for his country.

His latest however was an assured knock - that included 10 fours - to bring some needed momentum back to the tourists, and will return to the crease in a bid to reach three figures and push India beyond 300 on Thursday.

Seamers struggle for Bangladesh

Ebadot Hossain and Khaled Ahmed led the hosts' bowling attack out of the gates in Chattogram, but both failed to really cause problems the longer the first day wound on.

With just one wicket between them - that of Rahul, early on - they looked lacking in threat compared to the rest of their team-mates, with few full balls between them.
