Bill Belichick believes it is too late in the season to rip up the playbook for the New England Patriots, even as the perennial contenders continue to struggle with their form.

A 24-10 loss to the Buffalo Bills last Thursday saw the Foxborough outfit drop to 6-6 for the season, leaving them outside the AFC's wild card slots with a handful of games to go.

Though there is plenty of time to still salvage their season, the Patriots appear to be in something of a rut, with quarterback Mac Jones involved in a sideline outburst last week.

Belichick, however, will not introduce wholesale changes, claiming they are too deep into the season to do so, and stating they merely need to execute their existing tactics.

"I think we need to do what we're doing better," he told radio station WEEI. "I don't think at this point making a lot of dramatic changes. It's too hard to do that.

"If we can just do, consistently, what we're doing, I think we'll be all right. We just haven't been able to have enough consistency. That's hurt us.

"It's not one thing. One time, it's one thing, [and] next time, it's something else. We just have to play and coach more consistently.

"I think we'd all certainly like to be doing better than what we've been doing, from a record standpoint and from an individual execution [standpoint]. But we're going to look ahead and not backward."

The Patriots are not in action for another week now, and will return to the field against the struggling Arizona Cardinals next Monday.

Baker Mayfield will be released by the Carolina Panthers on Monday, bringing an end to a brief and disappointing stint with the franchise.

The first overall pick of the 2018 NFL Draft was traded away by the Cleveland Browns in July, with the Panthers giving up a conditional fifth-round draft pick.

After competing with Sam Darnold for the starting quarterback berth, Mayfield started the season as QB1 until suffering a high-ankle sprain in a Week 5 loss to the San Francisco 49ers – returning in Week 8, when he was backup for P.J. Walker.

Having made his last appearance in a Week 11 defeat to the Baltimore Ravens, the NFL Network's Ian Rapoport reported Mayfield will be released by the Panthers and will hit the waiver wire on Monday.

Mayfield will depart the Panthers with a disappointing 1-6 record, throwing as many interceptions as touchdown passes (six).

A pass completion percentage of just 57.8 per cent is the second-worst across the NFL, only ahead of the New York Jets' Zach Wilson (55.6 per cent).

Kyle Shanahan believes the San Francisco 49ers will still "have a chance" with quarterback Brock Purdy after he was thrust into the starting role following a season-ending injury to Jimmy Garoppolo.

Garoppolo suffered a broken foot on the 49ers' first drive of their thrilling 33-17 win over the Miami Dolphins on Sunday, which maintained San Francisco's one-game lead atop the NFC West at 8-4.

Purdy was the final pick in the draft this year, earning him the tag 'Mr Irrelevant', but he is now the focus of San Francisco's season after an encouraging performance in relief of Garoppolo.

The former Iowa State quarterback completed 25 of his 37 passes for 210 yards, two touchdowns and an interception, the Niners outscoring the Dolphins 30-10 after Garoppolo left the game as San Francisco's top-ranked defense rattled Tua Tagovailoa and the NFL's most explosive offense.

Now the 49ers, a team who had Super Bowl aspirations with Garoppolo under center after he took over from injured 2021 third overall pick Trey Lance, must try to achieve their goals with Purdy under center.

While most may believe their hopes are now over, Shanahan is not giving up.

"What impressed me about Brock in [training] camp," Shanahan said, "is he was always willing to let it rip.

"He's decisive. He started for years [at Iowa State] at a high level. You gotta have some balls to play quarterback in this league, and he does. We think we'll have a chance with him."

Purdy will this week prepare for his first start, which will come against the man regarded as the greatest of all time, Tom Brady, and the Tampa Bay Buccaneers.

"Pretty cool," Purdy told King when asked about going against Brady. "The GOAT. He's been playing football longer than I've been alive."

But Purdy knows he will not have to do it alone, as he enters arguably the best offensive ecosystem in the NFL with Shanahan calling the plays for an attack stacked with weapons, and he also has the assistance of a defense that forced three turnovers from Tagovailoa as the 49ers beat a team led by former offensive coordinator Mike McDaniel.

"I know the question is, can I step in and continue this ride of what our team has done?" added Purdy.

"It's not just a one-man show or anything like that. What Jimmy did for this team was amazing in terms of getting it rolling and getting us on a streak to win.

"The challenge for me is like, man, can I step up in that position and continue to feed those guys? Get them the ball. Make the right checks in the run game. Allow the defense to play great and play with them. That's the challenge for me and that's how I look at it and I'm excited for it."

FIFA has opened disciplinary proceedings against the Uruguayan Football Association and four of the Celeste's players – including Edinson Cavani and Diego Godin – following the team's furious reaction to their World Cup exit.

Uruguay failed to escape Group H despite Friday's 2-0 win over Ghana, as South Korea advanced at their expense following their comeback victory against Portugal.

Diego Alonso's team were ultimately eliminated on the basis of goals scored, and reacted angrily when Cavani was denied a late penalty after going down in the Ghana 18-yard box.

Social media footage showed the former Manchester United striker pushing the VAR monitor over after the final whistle, while several other Uruguay players surrounded referee Daniel Siebert.

FIFA detailed the charges, alleging misconduct of Uruguayan players and officials, offensive behaviour and discrimination, in a statement released on Monday.

The statement also said Uruguay quartet Cavani, Godin, Jose Gimenez and Fernando Muslera were being investigated separately for alleged offences relating to offensive behaviour, violations of the principles of fair play and misconduct. 

Speaking after the game, which almost certainly marked the end of his World Cup career, striker Luis Suarez declared: "FIFA is always against Uruguay".

In a separate statement, FIFA revealed Serbia would also face charges of misconduct, discrimination and failure to preserve order and security following their fractious 3-2 defeat to Switzerland on the same day.

Serbia's loss ensured they finished bottom of Group G, while Switzerland advanced to the last 16 by joining pre-tournament favourites Brazil on six points.

A fully fit Sergi Roberto was among a small group of Barcelona players who returned to training on Monday.

The versatile 30-year-old has not played since dislocating his left shoulder after scoring in Barca's 4-0 thrashing of Athletic Bilbao in October.

Sergio Roberto was cleared to train at the Ciutat Esportiva Joan Gamper over three weeks before the Blaugrana are back in action against Espanyol on December 31.

Defender Ronald Araujo also reported for training to continue his recovery from a groin injury that prevented him from playing for Uruguay in the World Cup.

Franck Kessie was also out on the pitch as he works his way back a hamstring injury.

Midfielder Kessie has been linked with Inter, Tottenham, Aston Villa and Fulham just five months after joining the Catalan giants from Milan on a free transfer.

Hector Bellerin, Marcos Alonso and Inaki Pena trained following a fortnight off while many of their team-mates were at the World Cup.

Head coach Xavi will welcome back more players who are no longer playing in the tournament in Qatar later this week.

Luis Diaz is among the 33 players Jurgen Klopp is taking with him for Liverpool's training camp in Dubai.

The Premier League side are heading to the United Arab Emirates on Monday for warm-weather training in preparation for the resumption of domestic football at the end of the month, following the break for the World Cup in Qatar.

Diaz – who has four goals and two assists in 12 games for Liverpool this season – has been out of action since suffering a knee injury in the 3-2 defeat at Arsenal on October 9, but the Colombian attacker is expected to be fit to take part in team training during the trip.

Fellow injured team-mates Joel Matip, Naby Keita, Diogo Jota and Arthur Melo are also included in the travelling party, though the latter two are not thought to be close to returning and will simply just be given a change of scenery in their rehabilitation.

Liverpool will play friendlies against Lyon and Milan while out in Dubai, before returning to face Manchester City in the EFL Cup fourth round on December 22.

With the Merseyside club only having seven players at the World Cup, manager Klopp has been able to take a strong squad, which also includes Mohamed Salah, Andrew Robertson, Thiago Alcantara and Roberto Firmino.

Darwin Nunez – who was eliminated in the group stage with Uruguay – will join up with the squad next week, with Dubai only a short flight from Qatar.

Christian Horner was not surprised to hear of Mattia Binotto's departure from Ferrari and rubbished speculation he would leave Red Bull to fill the vacancy.

Ferrari announced last week that Binotto had handed in his resignation as team principal after a frustrating season, where the team fell short of their objectives despite a fine start to the campaign.

An error-strewn year saw Charles Leclerc lose a 46-point advantage over Max Verstappen and Red Bull, eventually finishing a distant second-place to the two-time world champion.

Ferrari's hunt for a successor to Binotto has seen Horner linked with a move across the paddock but he affirmed his commitment to Red Bull.

Asked whether he was surprised by Binotto's exit, Horner told Sky Sports: "Not really. It is obviously Ferrari's choice.

"I think it will be the sixth team principal I have sat opposite since I've been at Red Bull. Obviously, it's very difficult for him. They had a great car this year, they were very competitive.

"My commitment is very much with the Red Bull team. I've been there since the beginning and have a really close attachment."

Verstappen will be looking to hand Red Bull a third consecutive drivers' championship in 2023, as well as retaining the constructors' championship, but Horner expects a tougher fight when the season begins in March – predicting Mercedes to be back near the top.

"Both those guys [Lewis Hamilton and George Russell] had great seasons. George finishing ahead of Lewis in his first year with the team was an impressive performance but Lewis is obviously still right there," Horner added.

"You've got to assume they're going to come back fighting hard next year, Ferrari as well will be looking to make progress, so it's set to be a really tough season."

Red Bull will also have to cope with the penalty issued for breaching Formula One's budget cap, resulting in a reduction of time allowance in the wind tunnel.

However, with development of the 2023 car already well underway before the punishment was issued, it is expected that the biggest impact from the penalty will be felt in 2024.

Walid Regragui is targeting a history-making victory over Spain as he insisted his Morocco team have put any negativity behind them.

Morocco have been one of the surprise packages of the World Cup in Qatar, with the Atlas Lions shocking Belgium on their way to winning Group F, which also included 2018 runners-up Croatia.

Regragui has done an impressive job since taking over in August, with an own goal against Canada in the group stage the only time his side have conceded during his tenure.

Morocco last reached the knockout stage of a World Cup in 1986, when they lost to West Germany.

They will have to beat a European heavyweight in the form of Spain to make the last eight for the first time in their history.

The countries met in the group stage of the 2018 World Cup, with Iago Aspas' late goal denying Morocco victory in a feisty 2-2 draw in Kaliningrad.

"Revenge? No, we're not seeking revenge at all," Regragui said when asked about that game. "We're not looking at the past, we’ve got a new generation and for me the mentality has to change, the negative aspects are the old Morocco.

"It's not the same team as in 2018, not the same Spain team as in 2018. It's two high-level teams coming up against each other. I don't even think we should be talking about revenge."

Spain and Morocco have a complicated relationship, politically and socially, and asked if this was the most important game in Morocco's history, Regragui replied: "I hope in the future there will be more important games, hopefully in the quarter-finals.

"We can't change what happened against Germany in 1986. We've got 24 hours to prepare for the game, make history and be the only ones to do so in Morocco.

"We are going to give it our all and not have any regrets. We don't want to leave the competition with regrets."

Morocco are the only African or Arabian team left in the tournament following the elimination of Cameroon, Senegal, Ghana, Tunisia, Saudi Arabia and Qatar, but Regragui does not believe that adds extra pressure.

"On the contrary, we don't have anything to lose. We will come out swinging, with a winning attitude, to hoist the Moroccan flag high," he said.

"We want to make all Arabs and Africans happy and we want their prayers and support to give us that extra ingredient. Before it was just Moroccans, now we will add the Arabs and Africans with their support and prayers.

"There will be millions of people watching. We don't want any regrets, we want to give the best of ourselves. 

"My work is to find the balance. It's not about doing too much to minimise that they could pull off something beautiful. We shouldn't go out with any complex, yes we are the underdog but we should go out and play without regrets.

"We've united Moroccans behind this team – that's the biggest victory we could have."

Kyle Walker can counter Kylian Mbappe when England face France in the World Cup quarter-finals as the Manchester City star is "the best right-back in the world" to face the forward, according to Gary Neville.

The Three Lions set up a last-eight match with Les Bleus after seeing off Senegal with a 3-0 victory inspired by Jude Bellingham and Phil Foden.

Gareth Southgate's side will face one of the toughest tests in world football against Didier Deschamps' defending champions, particularly with Paris Saint-Germain forward Mbappe in fearsome form.

But Neville feels England are well-equipped to keep him quiet, pointing to Walker as the key man who can thwart the threat posed by the 23-year-old.

"I think we have the best right-back in the world to be able to deal with Kylian Mbappe," the former England and Manchester United full-back told Sky Sports. "In terms of physicality, pace and experience, I can't think of anyone better to match Mbappe than Kyle Walker.

"That's not to say he'll keep him quiet for 90 minutes as Mbappe is sensational and special. But we have a chance as Walker can match him in certain areas."

Qatar 2022 marks the third successive tournament at which England have made the quarter-finals, having been beaten semi-finalists at Russia 2018 before losing the Euro 2020 final on penalties. 

Neville was part of the England side that reached the Euro 1996 semis, while he was also in the squad that suffered quarter-final shoot-out losses to Portugal at Euro 2004 and the 2006 World Cup.

Nevertheless, he is all too aware of the rarity of the occasion for Southgate's squad, adding: "It's a game of a lifetime on Saturday.

"When I think back to my own career, these games are once-or-twice-in-a-lifetime opportunities. They don't come around in your life very often."

In facing the reigning holders, Neville believes the pressure will be off, with defeat not likely to be considered an upset in the way a loss to Senegal would have been.

"I don't think the lads will be able to wait for it," he added. "This is a game we can lose we know that, they are world champions and a fantastic team.

"I always think you can go and enjoy games like this as there is less pressure than playing against Senegal. As if you get knocked out there, all hell breaks loose."

Breel Embolo hailed Cristiano Ronaldo as an inspiration and Kylian Mbappe as a role model ahead of Switzerland's World Cup last-16 tie against Portugal.

Embolo has impressed for the Swiss in Qatar, scoring twice in the group stage.

That is one more goal than Ronaldo has managed, with the Portugal captain netting only in their opening win over Ghana, with the goal coming from the penalty spot.

It did, however, make Ronaldo the first man to score at five different World Cups, and Embolo is honoured to get the chance to go up against the 37-year-old on the biggest stage.

"I think Cristiano, not just for forwards, but for all athletes, is a great inspiration and is enriching for our time," he said in a press conference.

"You can only learn from someone like him. As a player and a person, it's an honour to be facing him."

France star Mbappe, meanwhile, has been in superb form, scoring five goals to lead the charge for the Golden Boot, with his excellent double against Poland on Sunday sending Les Bleus into a quarter-final against England.

Mbappe already has nine World Cup goals to his name, as many as Lionel Messi and more than Ronaldo (eight). Aged 23 years and 349 days, he is the youngest player to score five knockout-stage goals at the competition since Brazil great Pele in 1958.

Embolo is almost two years older than Mbappe, but the Monaco forward still sees him as a player to look up to.

"He's incredible. He's 23 years old, he's an incredible player, I know him from Ligue 1 and he is a role model even for me," Embolo said of Mbappe.

"What he's doing at the moment is really impressive, so I want to congratulate him, he is extraordinary.

"Nine goals in World Cups at 23 – it says everything about him. I really wish him all the best, and for him to score nine more World Cup goals."

After a full-blooded victory over Serbia to make the last 16, Switzerland are looking to win three games in a single World Cup tournament for the first time in their history.

Asked if this was the most promising Swiss squad he had been a part of at a major tournament, Embolo replied: "It's like all generations, there is a change. I joined this group six, seven years ago, so it's difficult to say this is the best generation.

"There have been very great players and these players showed us how to integrate, like Yann Sommer or Granit Xhaka. It's important to keep these values in the team and transmit to the next generation.

"If I learned something it's that if we had challenging times in our lives or at our clubs but we were always together."

This will be the third meeting between Portugal and Switzerland in 2022, having faced each other twice in the Nations League in June.

Portugal won 4-0 in a match played in Lisbon, before Switzerland won 1-0 in Geneva a week later.

"We are ready, the squad is complete. It's a big opportunity for us to make history for Switzerland, we have seen how euphoric the Swiss people are about us being at this stage," said coach Murat Yakin.

"Statistics and the past don't matter, we will focus on this game. We are familiar with this opponent and we've proven we can beat them. Everything else is history."

James Anderson says England's incredible 74-run Test victory over Pakistan may be the best he has ever played in.

The tourists took a 1-0 lead in dramatic fashion late on the final day at Rawalpindi Cricket Stadium, Jack Leach taking the final wicket with the light fading rapidly.

Seamers Anderson and Ollie Robinson were outstanding, generating reverse swing with an old ball on a placid pitch as Pakistan were bowled out for 268 in a run-fest after a bold day-four declaration from Ben Stokes.

Anderson took 4-36 and Robinson 4-50, while Stokes also bowled brilliantly in England's first away Test victory over Pakistan for 22 years - and only their third of all time in the country.

The evergreen Anderson felt the victory on a surface that was a batter's paradise could be the finest of his long Test career.

Asked if he had seen anything like it, he told Sky Sports: "I don’t think I have actually. It's probably one of the best wins I've been involved in, if not the best.

"On a pitch like that, to play the way we did, to score runs at the rate we did, we gave ourselves a chance to get the result.

"It was an unbelievable effort from everyone. We knew it was going to be difficult, it just feels like with Ben and Brendon [head coach McCullum], their mantra is 'we've got to take wickets'. We look to take wickets all the time.

"We knew it was a big push, we dug deep to get anything out of that wicket."

Anderson, Robinson and Stokes bowled 66 second-innings overs between them in a Herculean effort in the heat.

The 40-year-old Anderson said "I think we all kept each other going. At times each of us was tired and one of us would pick the other up. We managed to get through some long spells.

"It's nice to have the win but I don't think tomorrow will feel great for me. It was a long five days."

Gavi is retaining faith in Spain's style of player even if the impressive teenage star knows La Rojo must learn from the mistakes made against Japan when they face Morocco in the last 16 of the World Cup.

Spain were on course to top Group E when Alvaro Morata headed an early opener on Wednesday, but goals from Ritsu Doan and Ao Tanaka helped the Samurai Blue leapfrog their opponents in stunning fashion.

For three incredible minutes, Spain even looked set to join Germany in making an early exit as Costa Rica briefly occupied second place.

Spain ultimately survived despite seeing their seven-match unbeaten run (excluding shoot-outs) at the World Cup halted, and Gavi says Tuesday's game represents a chance to right some wrongs.

"The match against Japan has to serve as a lesson for what is to come. Luckily, that defeat has been resolved and we are clear about what we have to do," Gavi told Marca.

"We are in the round of 16 and there are some very good teams that haven't been able to do it. That's why we have to really think that pressure is a privilege."

Spain completed 2,489 passes in their group-stage campaign, their most at a single tournament on record (since 1966), while their tally of 969 passes against Japan was a record for a losing team at the tournament.

While Morocco showed their counter-attacking quality to claim four points from games against Croatia and Belgium, Gavi believes Spain must stick to their principles.

"We are not going to lose focus on the goal, which is to win the World Cup," he added. 

"We are going to look for it by being faithful to what we have been doing all these years. It would be a mistake to give up everything we believe in."

Morocco are featuring in the knockout stages of a World Cup for just the second time, having been beaten at this stage by West Germany in 1986.

The Atlas Lions are chasing a slice of history on Tuesday, when they could match the longest unbeaten run managed by an African side at the World Cup – currently Cameroon's five-game sequence between 1982 and 1990.

After a 2-1 win over Canada ensured Morocco topped Group F, coach Walid Regragui called for his side to aim high.

"We didn't come just to say 'oh, we almost got close'," he said. "We need to get the results as all the European or South American teams do. We need to emulate them."

PLAYERS TO WATCH

Morocco – Hakim Ziyech 

While Romain Saiss and Nayef Aguerd are likely to be busy in the Morocco backline, Regragui's men will carry a threat at the other end – chiefly through Chelsea creator Ziyech.

Ziyech has played more passes into the box (17) and created more chances (4) than any other Morocco player at the World Cup, as well as leading his team-mates for ball carries (43) and combined distance carried (477.6 metres).

While Ziyech's counter-attacking prowess is clear, he also scored his first World Cup goal last time out, and the 29-year-old could be a thorn in Spain's side.

Spain – Alvaro Morata

While Barcelona playmakers Gavi and Pedri have stolen the headlines for Spain in Qatar, fine margins can often decide knockout games – and Morata's contribution could be key. 

Though maligned by some, Morata has been consistent in front of goal at this tournament, hitting the net on each of his three appearances despite playing a total of just 126 minutes.

Morata started two of Spain's three knockout games at Euro 2020 last year, and if he can reward Luis Enrique's faith with another goal, he will join David Villa as just the second Spanish player to score in four consecutive World Cup matches.

PREDICTION

Spain have never lost in their three previous meetings with Morocco (W2 D1), and Opta's prediction model makes them strong favourites to advance to the last eight, giving them a 61.3 per cent chance of victory.

However, Morocco did claim a 2-2 draw in the teams' only previous World Cup contest in 2018, and a repeat – which would mean extra-time and potentially penalties – is given a 24 per cent chance. 

The Atlas Lions have provided one of the great underdog stories of this tournament, but their chances of an historic victory are rated at just 14.7 per cent, making them big outsiders.

Cristiano Ronaldo appears to have found his next club.

Marca reported on Monday the former Manchester United forward was set to join Al Nassr on January 1 after agreeing his exit from Old Trafford last month.

News of a lucrative contract offer from the Saudi Pro League club emerged last week, with Ronaldo said to be in line to earn more than £100million a year.

The 37-year-old, who is still in World Cup action with Portugal, appears destined to head outside of Europe for the first time in his storied career.

Al Nassr are not a renowned name in Europe but have enjoyed huge success in Saudi Arabia, so what can Ronaldo expect should he head to Riyadh?

Who are Al Nassr?

Formed in 1955 and winning the Saudi top flight in their very first season, Al Nassr have nine championships to their name – second only to Al Hilal's 15.

Indeed, Al Nassr and Al Hilal have between them won eight of the past nine Pro League titles, although Al Hilal have taken the most recent three in a row.

The two sides contest the Riyadh derby, with Al Hilal winning the most recent edition 4-0 in March.

Ronaldo's new team-mates

Saudi Arabia's entirely Saudi-based World Cup squad included six Al Nassr players, with Sultan Al Ghannam and Abdulelah Al Amri appearing as substitutes in the shock defeat of Lionel Messi's Argentina.

But the better known players in the Al Nassr squad are likely those from foreign shores.

Cameroon's World Cup star Vincent Aboubakar is joined by former Brazil midfielder Luiz Gustavo, along with three-cap Argentina international Pity Martinez.

Goalkeeper David Ospina has represented Colombia at several World Cups, as well as turning out for Arsenal and Napoli, while Talisca was once a highly rated young forward at Benfica and has scored regularly at Al Nassr.

South Korea's left-back Kim Jin-su is out on loan.

Potential debut date

The Saudi season paused in October ahead of the World Cup but will begin again next week.

Al Nassr are set to play Al Hilal on December 26, meaning Ronaldo will have missed the derby if he joins in January.

The legendary striker could be in the line-up against Al Tai in Al Nassr's first match of 2023 on January 5, however.

Al Shabab lead the Pro League by three points ahead of second-placed Al Nassr, with a top-of-the-table clash lined up for January 13.

Ruben Dias pleaded with the Portuguese media to promote unity rather than trying to create a divide following criticism of Cristiano Ronaldo.

Fernando Santos' Portugal side will face Switzerland in the last 16 of the World Cup on Tuesday after winning Group H despite a shock defeat to South Korea on matchday three.

Ronaldo endured a particularly difficult day against the Taeguk Warriors.

He failed to hit the target with either of his two shots and was caught offside three times, with a couple of those situations raising questions of his concentration.

The 37-year-old was withdrawn in the second half and simultaneously had a disagreement with South Korea forward Cho Gue-sung.

Since then, a poll on the website of Portuguese newspaper A Bola suggests 70 per cent of supporters want Ronaldo to be dropped, and defender Dias had a defiant response.

"I actually think you shouldn't ask Ruben Dias that, but you should ask that to Cristiano Ronaldo," the defender told reporters.

"I'd like to take this moment to say, in this tournament the press is supporting us and Ronaldo, so I'd like to make an appeal to the press; as we progress, instead of creating a divide, create unity, then who knows maybe we'll have good strength and positive energy for all involved."

If Ronaldo was to be dropped, Rafael Leao would be among the favourites to step in.

The Milan forward came on as a substitute in all three of Portugal's group games, but Santos appears to think he still requires some adaptation work.

"He has a huge potential, and I think he will have a promising career," Santos added.

"But of course he faces the difficulties of any player who has a place in a club like his, where he plays more on the left and playing for the club he has more freedom.

"But at national team level, he needs to adapt to the others, to players who excel for their clubs but have a different [role] at the national team."
