A brusquely assured first-half demolition job from Bayern Munich reaffirmed their Bundesliga title defence credentials in a 4-0 win over Bayer Leverkusen.

Goals from Leroy Sane, Jamal Musiala and Sadio Mane all before the interval put the champions firmly in the driving seat for a deserved victory at Allianz Arena on Friday, before Thomas Muller added a fourth close to the end.

After a dismal domestic run saw them go four league games without a win, questions had been asked about Julian Nagelsmann's side and their purported chances of claiming another top-flight crown.

But for now, they have been emphatically silenced, while Gerardo Seoane's side saw their horror-show start to the campaign worsened in painful fashion on the road.

It took Sane just three minutes to split open the visitors, fed off the right wing and able to roll a deflected strike beyond the wrong-footed Lukas Hradecky.

Musiala followed suit just after the quarter-hour mark, playing a one-two with Muller off a long ball before squeezing a shot in, and Sane added a third from the edge of the box six minutes from the break.

Mane saw a second overturned 10 minutes after the interval when VAR deemed Odilon Kossounou to have been fouled, but that call was likely scant consolation for Leverkusen.

Yet Bayern were not done, and when Muller pressed Hradecky late on, a tragicomic slip from the goalkeeper left an open net for the veteran to turn home and round off a comprehensive win.

Red Bull chief Christian Horner has described claims of the team breaking Formula One's $145million (£114m) budget cap as "speculation", though Ferrari and Mercedes state the situation is an "open secret".

Two teams have reportedly breached F1's spending regulations, one of which is by a "significant amount", and Red Bull have swiftly been attributed with guilt – although there is no proof.

Horner told BBC Sport that it was "purely speculation" and added to Sky Sports he was "not aware" of any breach.

"We are certainly not aware of any [breaches]. The accounts were all submitted way back in March, so it's been a long process with the FIA going through, and we are in that process as we speak," he said.

The FIA will issue certificates of compliance on October 5, or announce any breaches, but both Mercedes and Ferrari suggested there was an understanding on the grid that two teams are at risk of punishment.

Mercedes team principal Toto Wolff claimed one such party was "fundamentally massively over". 

"There's a team in minor breach, which is more procedural, and another team that is fundamentally massively over and that is still being looked at," he said. "That's an open secret in the paddock."

And there was a similar view from Ferrari, with racing director Laurent Mekies saying: "It's now no secret that two teams broke the 2021 budget cap regulations, one by a significant amount, the other less so."

The situation creates a significant headache for the FIA, with the 2021 season already shrouded in controversy after Max Verstappen pipped Lewis Hamilton to the title in the final race in Abu Dhabi, with race director Michael Masi failing to implement the rules correctly after a late safety car.

Emergence of further controversy will not be welcomed, and questions will be asked as to why the results are so delayed, with F1 now in the back end of the 2022 season and Verstappen waltzing to a second title in a row.

Punishments for budget cap breaches can be severe, with potential points deductions for minor violations, while the heaviest punishment for a larger breach includes banning a team or driver.

A breach last year would also have a knock-on effect into the current campaign as the cap includes development of the car for the following season.

Novak Djokovic sealed his place in the final four at the Tel Aviv Open after beating one of his "best friends" Vasek Pospisil on Friday.

The Serbian was made to work hard by his Canadian opponent, particularly in the first set, but eventually won 7-6 (7-5) 6-3.

Djokovic was particularly impressive on his second serve, winning 70 per cent of them, only four per cent less than his first serve success rate, and he hit just eight unforced errors compared to Pospisil's 21.

"It was a great, positive win," Djokovic said afterwards. "Vasek is one of my best friends on the Tour. We have known each other for many years. It is never easy playing someone you respect so much and like so much, but we are both professionals and wanted to win the match and you can see that.

"I think the level of tennis was really high. Especially towards the end of the first set and the second set. Credit to him for fighting. It's great to see him back."

The number one seed will play Roman Safiullin in the semi-finals after the Russian beat Arthur Rinderknech 6-4 6-1.

Constant Lestienne came through a tight contest with Maxime Cressy, winning 6-7 (4-7) 6-3 7-6 (7-3), and will face number two seed Marin Cilic in the other semi after the Croatian was handed a bye following Liam Broady's withdrawal prior to their match.

At the Sofia Open, Jannik Sinner remains on course for a third successive title at the tournament, setting up a final-four encounter with Holger Rune after easing past Aleksandar Vukic 6-2 6-3, with Rune eventually dispatching Ilya Ivashka 6-2 5-7 6-4.

The other semi-final in Bulgaria will see Lorenzo Musetti take on Marc-Andrea Huesler after both won their respective quarter-finals against Jan-Lennard Struff and Kamil Majchrzak.

Phil Salt hit a blistering 88 as England beat Pakistan by eight wickets on Friday to level up their seven-match T20I series at 3-3 in Lahore.

Pakistan recovered from a slow start that saw them 15-2 at one point to post 169-6 at the Gaddafi Stadium, thanks in large to the brilliant Babar Azam (87 not out).

But England made easy work of the chase as they reached 100 from seven overs to set up a decider on Sunday.

Without in-form Mohammad Rizwan, Pakistan initially struggled as Mohammad Haris (7) and Shan Masood (0) fell early on, leaving Babar to do much of the leg work.

Haider Ali (18), Iftikhar Ahmed (31) and Asif Ali took their side to 136-4, but the latter upper cut to Reece Topley for nine runs and Mohammad Nawaz (12) followed soon after.

Babar's 87 did at least give England something to think about, but Salt and Alex Hales put on an opening partnership of 55 off 23 balls, before the latter was removed for 27.

Salt reached his half-century off just 19 balls en route to an unbeaten 88, including the decisive shot as England posted 170-2 to level things up.

Babar brilliance not enough

Pakistan were without run machine Rizwan but Babar stepped up with 87 runs off 59 balls, which included three sixes and seven fours.

Babar surpassed a milestone 3,000 T20I runs in the process, yet it was not enough to steer the hosts to an unassailable series lead.

England ease to victory

The tourists were set 170 to avoid a third successive T20I defeat to Pakistan for the first time ever and had no trouble in reaching that target.

Only once before – against New Zealand in November 2019 (6.4 overs in a game reduced by rain to 11 overs) – have England previously reached 100 from seven overs.

Salt played a key part in that as he underlined his credentials to partner Jos Buttler at the upcoming T20 World Cup.

The Boston Celtics and veteran forward Blake Griffin have agreed to a one-year contract, ESPN's Adrian Wojnarowski reported on Friday.

Griffin, 33, will add depth for a team that has endured a series of injuries in the frontcourt before the 2022-23 season has even begun.

Danilo Gallinari, Boston's top free agent acquisition of the offseason, suffered a torn ACL in August, while starting center Robert Williams III underwent knee surgery last week, keeping him away from basketball activities for at least two months.

A six-time All-Star selection, Griffin averaged 6.4 points and 4.1 rebounds in 56 games with the Brooklyn Nets last season.

Griffin's signing comes in the wake of coach Ime Udoka's year-long suspension for an inappropriate workplace relationship that is still clouded in mystery.

The Celtics tip off their season on October 18 against the Philadelphia 76ers.

The Golden State Warriors began their pre-season with a 96-87 win against the Washington Wizards in Saitama, Japan thanks to an impressive showing from James Wiseman.

A sold-out Saitama Super Arena watched on as Wiseman top-scored with 20 points from almost 24 minutes on the court.

However, it was understandably Japan's own Rui Hachimura who garnered the most noise from an adoring crowd, registering 13 points for the Wizards and, like Wiseman, a game-high nine rebounds.

After the game, coach of the defending NBA champion Warriors Steve Kerr conceded it had not been the highest-quality contest due to it being so early in pre-season, but told reporters how pleased he was with Wiseman's performance.

"James has had a really good few days of practice," he said of the 21-year-old. "His understanding of spacing and defensive communication, being in the right place, he just has a much better sense of the NBA game now than he did a couple of years ago.

"He's been putting a ton of work in, last year despite injury, he was studying and watching tape and learning from our older guys, so I couldn't be happier for James."

Kerr referenced the "really good atmosphere" and also spoke about the adulation received by Washington's Hachimura, and the potential benefits for the NBA's global appeal as a result.

"You see how popular he is," he said. "When he spoke to the crowd they went crazy, and it was a great moment.

"The game has been a global one for a long time but the more international stars we can get, the more popular the game becomes in that particular player's country, so hopefully we'll have more and more players coming from Japan to the NBA.

"You can see it's a basketball-crazed country, people love it here and it's fun to be a part of."

A second game between the two teams in Saitama will be played on Sunday.

The NFL returns to London on Sunday with Tottenham Hotspur Stadium playing host to the Minnesota Vikings' clash with the New Orleans Saints.

Back-to-back defeats against the Tampa Bay Buccaneers and the Carolina Panthers have left the Saints looking for a response in their trip across the pond, with those losses coming despite impressive defensive performances. The Saints have held their opponents to fewer than 250 net passing yards and no more than one TD pass in nine straight games.

This season, the Saints have allowed a total of 551 passing yards (183.7 per game), which stands as the fifth-best record in the NFL. On the ground though, the story is far different – allowing 418 yards total (139.3 per game), the seventh-most.

Offensively, no team has lost more fumbles (4) than the Saints this season or thrown more interceptions (5), resulting in a turnover differential of minus 6 – again more than anyone else.

On the opposing side, the Vikings have allowed a total of 413.3 total yards per game, sitting behind only the Ravens (458) for the highest total of yards allowed per game. However, the Ravens have only allowed 18.3 points per game this season – enough to slot them into the top 10 for the fewest conceded this term.

Kirk Cousins will fancy his chances against the Saints, as he boasts a career passer rating of 126.7 against New Orleans in the regular season; the highest of any quarterback against a single opponent in the Super Bowl era (minimum 125 attempts).

In his four career matches against the Saints, Cousins has thrown 12 TD passes and just one interception, though he has lost each of his last three matchups against New Orleans.

Barcelona boss Xavi has played down concerns over the future of captain Sergio Busquets, insisting the Spain international remains "key" to his plans at the club.

A difficult start to the season for the 34-year-old, including a red card against Rayo Vallecano, seems to have stoked further suggestions this campaign could be his last at Camp Nou.

With Barca still likely to need to cut their cloth accordingly amid their financial struggles, the Spain skipper could well be one key man to depart next year.

But the defensive midfielder has publicly downplayed a definitive answer on his future, and speaking ahead of his side's clash with Mallorca, Xavi reiterated that no decisions have yet been made.

"Busquets has said publicly that he hasn't decided anything," he stated. "He will make a decision at the end of the season and for me, he continues to be key."

With domestic and European concerns to field, Barca are set to enter a major period of fixture congestion, with a dozen games crunched into the month-and-a-half stretch ahead of the Qatar 2022 World Cup.

Several of Xavi's fellow coaches across the continent have voiced their displeasure at the intense calendar, but he is instead focusing on the need to take as many points as they can at home and abroad.

"We have 12 games until the break for the World Cup," he added. "It's a momentous stretch of the season. All games are going to be very important.

"Tomorrow we have to win and show our character. We have to show our strengths."

Barca will move into an enforced break this term thanks to the mid-season winter staging of the World Cup in Qatar, adding another tough dimension to an already gruelling campaign.

With FIFA having mooted plans in recent times to potentially expand the tournament to a biennial staging, Xavi feels there should be no further restructures or moves from its traditional off-season berth.

"FIFA plans to organise the World Cup every two years," he added. "Now we have the World Cup in Qatar during the winter period.

"I think it would be better if the tournament is compiled at a separate time. Then the other time is allocated to the clubs."

Richard Mansell overcame tricky conditions to shoot a four-under-par 68 to ensure he goes into the weekend at the top of the Alfred Dunhill Links Championship leaderboard.

Mansell carded the lowest score of the round to get to ten under par, helped by four birdies on the front nine as he battled through the wet and windy weather.

The Englishman now holds a two-shot lead over Sweden's Alex Noren in second, while Antoine Rozner and Niklas Norgaard Moller sit three shots behind the leader on seven under par.

Romain Langasque, who equalled the best-ever round at the Old Course at St Andrews with his opening round of 11-under-par on Thursday, endured a nightmare second day as he shot an eight-over-par 80 to fall to 19th.

Rory McIlroy was another to struggle with the conditions, with the world number two going round in 75 at Kingsbarns to drop to joint-43rd.

Scot Robert MacIntyre remains in contention after carding a second round of 70, while English pair Callum Shinkwin and Daniel Gavins are also in striking distance on five under par.

Premier League football returns in full fashion this weekend for the first time in four weeks, with the Manchester derby a highlight.

Free-scoring Manchester City have excelled so far this term, only dropping points in draws against Aston Villa and Newcastle United, while Manchester United have won their past four after starting the season with back-to-back losses.

United have already shown intent in key matches with victories against Arsenal and Liverpool, while City are yet to face one of the established 'top six' after their clash with Tottenham was postponed.

Ahead of the game, Stats Perform has dived into the Opta stats to highlight the key angles of the match.

City's pursuit of dominance

Victory for City would mark the third in a row in the Premier League against United for the first time since a streak of four wins between April 2013 and November 2014 – including a 4-1 triumph in this fixture last season.

Defeat for United would also be their 18th in the Premier League against their cross-city rivals, equalling Liverpool and Chelsea for the most losses they have suffered in the history of the competition.

City were last beaten at home against Tottenham in February and have lost only 15 of 117 Premier League matches at the Etihad Stadium with Pep Guardiola at the helm, though he has won only two of six in the league against United at the venue.

United's solid form

Four victories in a row in the Premier League for United, on the back of four consecutive defeats, has put Erik ten Hag's side in good form heading into a crucial stage of the season and the club have not won five league games on the spin since April 2021 under Ole Gunnar Solskjaer.

While City have home advantage on Sunday, the away side in the Manchester derby have won 21 times in the Premier League, with no fixture being won by the visitors more times in the competition's history – three of those being for United against Guardiola's City.

United have also won two of their past three against City at the Etihad Stadium, with a 2-0 victory in March 2021 and a 2-1 triumph in December 2019.

Haaland's haunts

Hat-tricks in back-to-back Premier League home matches heading into the Manchester derby have put Erling Haaland in with an opportunity to secure further history, with no player in the competition's history netting a treble in three consecutive home games before.

City's dominance at home is not just down to the former Borussia Dortmund man, however, as they have won each of their past seven Premier League matches at home, scoring at least three goals on each occasion – a run that stretches back to last season.

No team have won eight straight matches in the top flight of English football while scoring at least three goals in each since Tottenham between March and September 1965.

Guardiola's free-scoring side have scored 10 goals in the first half of matches and 13 in the second half, both of which are more than the eight goals United have in total – while United have conceded 75 per cent of their goals in the opening half (6/8).

Ten Hag seeks to end sorry run

Ten Hag has never faced off against Guardiola during the pair's managerial career and he will be looking to end a sorry run for United managers in his first Manchester derby since taking over at the club.

Each of the five previous United managers to have taken charge of a Premier League match against City in the league have lost their first – with David Moyes, Louis van Gaal, Jose Mourinho, Ole Gunnar Solskjaer and Ralf Rangnick all suffering defeats.

That leaves Alex Ferguson as the last United manager to win his first league match against City, which came way back in March 1987.

Manchester City will be without John Stones for Sunday's derby against Manchester United, Pep Guardiola has confirmed.

The centre-back was taken off during England's 3-3 draw with Germany on Monday with a hamstring issue.

Speaking at a press conference on Friday, Guardiola said Stones will likely be out for up to two weeks, meaning he will miss the clash with United as well as potentially another three games.

"He will be back when he will be ready," he said, later clarifying: "I think it will not be four, five, six weeks, it will be less. I don't know when he will come back but I think maybe 10 days, two weeks."

There was better news for another City defender though, with Aymeric Laporte back in training.

"Training really well," his manager said. "Training alone because everyone was with national teams, but yesterday and today he feels good."

City welcome an in-form United to the Etihad Stadium, with Erik ten Hag's men winning their last four Premier League games, leading to the Dutchman securing September's manager of the month award.

"I always expect the best," Guardiola said. "They come with good results against tough sides, with Southampton it's not easy but especially Liverpool and Arsenal at home, and yeah, good momentum for them."

The former Barcelona and Bayern Munich boss also compared the Manchester derby to El Clasico and Der Klassiker, suggesting it has been easier to manage derbies in Germany and England since his time in LaLiga.

"In Spain, Barcelona and [Real] Madrid is more noisy the days before, more media, everything. The rest, in Germany, here, perfect. You can work, people expecting, enjoy to watch the derby, that's all.

"It's important, big rival in the city. We will try to figure out what we're going to do and what we can do to beat them. No more than that.

"In these kind of games you don't have to make extra emotion, everyone knows it. The stadium will be full... I'm looking forward to it."

Liverpool manager Jurgen Klopp admits Trent Alexander-Arnold has "space for improvement" defensively when questioned over the full-back not featuring for England.

The 23-year-old was called up by Three Lions' boss Gareth Southgate for the fixtures against Italy and Germany, but failed to get on the pitch in either as Chelsea man Reece James played both matches.

While Alexander-Arnold has shown plenty of attacking ability over his career, registering 45 assists for Liverpool in 167 Premier League appearances, his defensive capabilities have been questioned.

And Klopp feels Alexander-Arnold could become more solid going backwards, telling reporters ahead of Liverpool's match against Brighton and Hove Albion: "I see him differently. People say he's not a good defender. That's not true.

"He is a good defender, but he doesn't always defend good. That's true. That's what we're working on. He's a young player, he's 23, and there's space for improvement definitely.

"We only discuss it on the level we discuss it because his offensive impact is so extreme. Is he always exceptional? No."

Klopp also feels the discussion over Alexander-Arnold's role in the England squad is harming their chances at the upcoming World Cup, after former Aston Villa forward Gabby Agbonlahor said the defender should "retire" from international duty until Southgate left his position.

"We can now discuss selections until the World Cup starts. It's one of the reasons why you make massive stories of why the [England] team can't prepare properly," Klopp added.

"If you ask me for my honest opinion, it will create headlines, that's clear. Do you want that? It helps Germany maybe, but not England.

"If you want them to play a good World Cup, then don't cook it too hot. Otherwise, you discuss this until November, and don't let them work properly.

"I think you could see a little bit, England are slightly under pressure because they don't play to their full quality in this moment.

"Let them do the job, and criticise afterwards."

Casper Ruud stumbled to defeat against Japan's Yoshihito Nishioka as the French Open and US Open runner-up bowed out in the Korea Open quarter-finals.

World number two Ruud lost 6-2 3-6 6-2 in Seoul on Friday as the Norwegian found the going too tough in his first tournament in Asia for three years.

Ranked 56th before this week, Nishioka is one win away from vaulting back into the top 50, potentially going beyond his highest ranking of 48th if he reaches the final.

He said, quoted on the ATP website: "I feel great. My motivation is very high. I am playing very well, very smart."

Assessing top seed Ruud, Nishioka said: "I know he came from Europe and played at the Laver Cup, which is not easy matches. He wasn't settled on this court or this country yet, maybe. I was ready. I was focused on playing against him and I had a plan and it worked."

Nishioka had an outstanding run to the Washington final in August, before losing out to Nick Kyrgios in the title match. That was a major outlier in his season, which has consisted largely of early-round defeats.

His semi-final opponent will be American Aleksandar Kovacevic, a 24-year-old world number 222 who is enjoying the biggest week of his career. A 'lucky loser', handed his place in the draw when a spot opened up, Kovacevic has taken full advantage and beat compatriot Mackenzie McDonald 4-6 6-3 6-2 in their last-eight battle.

Canadian Denis Shapovalov, still seeking a first final appearance of the year, moved one step away by beating Moldova's Radu Albot 6-2 6-2, setting up a clash with American Jenson Brooksby, who was handed a bye due to Cameron Norrie pulling out with illness.
