Iga Swiatek warned the tennis schedule is "not safe" and "could cause injury" as she pulled out of the Billie Jean King Cup Finals.

The world number one was due to represent Poland in an event that will be staged in Glasgow from November 8-13, but withdrew on Monday.

That competition will start just a day after the WTA Finals finish in Fort Worth, Texas.

US and French Open champion Swiatek criticised governing bodies the WTA and International Tennis Federation (ITF), who run the Billie Jean King Cup, over the calendar.

"I was thinking it through a lot and discussing it with my team, but I will not be able to play at the Billie Jean King Cup in Glasgow," Swiatek posted in an Instagram story.

"It makes me sad. I'm very sorry, because I play for Poland whenever it's possible and I always give it my best.

"Playing in Poland this year [in the qualifiers] was an honour and I hoped to do this again at the end of the season.

"I'm disappointed that tennis governing bodies didn't come to an agreement on something as basic as the calendar of tournaments, giving us only one day to travel through the globe and changing the time zone.

"The situation is not safe for our health and could cause injury."

Inter head coach Simone Inzaghi believes his team need to play with "aggression and determination" against Barcelona in the Champions League on Tuesday.

Inzaghi is under fire after a run that has seen Inter lose four of their last six in all competitions, with a 2-1 home defeat to Roma at the weekend leaving the Nerazzurri ninth in Serie A, already eight points behind joint-leaders Napoli and Atalanta.

And Tuesday's match will see them host a Barcelona side in red-hot form, top of LaLiga and yet to lose a league match this season under the leadership of former midfielder Xavi.

In his pre-match press conference, Inzaghi outlined just how tough a task the game was going to be, while explaining how his team need to play at the San Siro if they are to get a result.

"Tomorrow is a great opportunity, knowing that we meet a very strong team, probably one of the best in Europe," Inzaghi told reporters.

"It is a complete, strong team with a lot of quality. They know how to do everything, they have pressing and ball recovery. It is a team that knows how to do everything in possession and non-possession.

"Barcelona are a very strong team, complete in all departments. They have a lot of quality, plus they have [Robert] Lewandowski.

"We will have to play a game of aggression and determination."

Inzaghi also had positive news about striker Lautaro Martinez's availability for the fixture, adding: "This morning Lautaro made an exam where no injury was evident.

"He finished the game [against Roma] fatigued, today he will do a partial training and we will see what his condition will be."

Christian Horner remains confident Red Bull did not breach Formula One's budget cap rules last season ahead of the results of an FIA investigation.

The constructor faced reports both they and Aston Martin spent more than the $145million during Max Verstappen's title-winning campaign in 2021.

As Sergio Perez stormed to victory at the Singapore Grand Prix, clamour over the findings reached fever pitch, with Mercedes principal Toto Wolff claiming the breach was an "open secret".

But Horner has reiterated his belief the team remain inside budget constraints, while continuing to linger the threat of legal action against his rival over comments he considers defamatory.

"We're absolutely confident in our submission," he said. "Our audit was signed off by our auditors. We believe we are comfortably within the cap.

"We will consider all of our options. It was totally unacceptable to make a completely unfounded allegation – and on the basis of what knowledge? Where is this source of information?

"It was a confidential submission between the team and the FIA. I have no idea of the compliance of any of our rivals. So where does that information supposedly come from?"

Verstappen holds a 104-point lead over Ferrari's Charles Leclerc, and is closing in on his second world title, though if the FIA were to find Red Bull in breach last season, there could potentially be future repercussions on his prospects.

Jonathan Taylor's knee injury is reportedly not thought to be serious, though the Indianapolis Colts' star is a doubt for their clash with the Denver Broncos on Thursday.

Taylor was injured as the Colts' uneven start to the season continued with a 24-17 defeat to AFC South rivals the Tennessee Titans on Sunday.

The defeat dropped the Colts to 1-2-1, with Indianapolis once again struggling to justify considerable offseason hype.

An extended absence for Taylor, who last year led the NFL with 1,811 rushing yards and 18 touchdowns on the ground, would deal another substantial blow to the Colts' hopes of returning to the postseason.

NFL Media's Ian Rapoport calmed fears of Taylor being out for the long term, but pointed out that the tight turnround could make it difficult for him to feature in Week 5.

The Colts are only half a game back in the AFC South race, but another defeat to a conference opponent in the Broncos would leave them in a potentially much more significant hole.

For Taylor's part, he was unsure whether he would be healthy to feature in Denver.

He told reporters of his ankle injury: "It just tweaked up a little bit, but I'm feeling good now.

"It was a lot of commotion going on. Things just happen so fast on the field. It's crazy."

Asked about his status for the meeting with the Broncos, Taylor replied: "I'm not sure yet, but we'll see how things are tomorrow [Monday] morning."

Julian Nagelsmann may shuffle his pack for Bayern Munich's Champions League game against Viktoria Plzen on Tuesday, with the depleted Bavarians set to host Borussia Dortmund four days later.

Bayern have started their Champions League campaign with back-to-back wins over Inter and Barcelona, and lead the duo by three points at the top of Group C.

Should they record another European win at the Allianz Arena next time out, Bayern will have won their first three Champions League matches for a fourth season in succession.

On the domestic stage, however, Bayern trail surprise pace-setters Union Berlin and Freiburg after an inconsistent run of results, and host rivals Dortmund on Saturday.

With Thomas Muller and Joshua Kimmich set to miss the Plzen match after contracting COVID-19, Nagelsmann is aware of the need to manage his squad.

"We need to rotate because of Joshua and Thomas, so there are different ways, there are so many options," Nagelsmann said at his pre-match press conference.

"You'll see tomorrow which I decide. We're still in a situation where we need to grab points. 

"It's important for the Champions League to win the game against Plzen, and also to keep the rhythm for the game against Dortmund, where there might be more pressure than in the Champions League.

"Plzen like to play defensively and counter-attack, and that could be a challenge. We'll try to get into our optimum phase considering what is still ahead."

Bayern have been heavily impacted by COVID-19 recently, with Manuel Neuer and Leon Goretzka withdrawing from the Germany squad after contracting the virus last month.

Nagelsmann offered a positive update on the conditions of Muller and Kimmich, and hopes to have them back after Tuesday's match, adding: "Thomas and Joshua don't have any symptoms, they're doing well. Of course, they would love to play, but nothing has changed.

"We can do the tests on Friday and if those go well, they are candidates against Dortmund. It depends on the tests we will do.

"In general, the incidence is high in Munich so it's a factor that concerns us. We've talked with the players. 

"They've had the suggestion that they're not going to go to the Oktoberfest since the officials took part, so no partying there!

"Outside of the pitch, professional players are normal people. Everybody's looking after themselves."

Nagelsmann also revealed Kingsley Coman will not feature against Plzen despite recovering from a muscle injury, but said Serge Gnabry had his full support if selected to start out wide.

"First of all, with Kingsley, he is doing well," Nagelsmann said. "He practiced well, he was great, but he's not going to be a part of tomorrow's game.

"We'll try to heighten that [his condition] in the next couple of days and then he's an option against Dortmund, but he's not going to start, that's for sure.

"He is doing well. I have good expectations that he can fill a position in the squad against Dortmund, it would be great to have him, and not so great for the opponent.

"I haven't decided 100 per cent, but Serge is certainly a candidate there. We have to see also what we will do against Dortmund, and what happens with Thomas.

"I've known Serge for ages and I think a lot of him. He doesn't worry too much on the field and plays freely. We have a good connection with each other."

Jurgen Klopp says there are no "instant" solutions in football as Liverpool look to bounce back ahead of their Champions League clash with Rangers.

The Reds failed to turn their rough form around upon their return to Premier League action this weekend when they were held to a 3-3 draw by Brighton and Hove Albion.

With just one win in their last four games across all competitions, Klopp's side - FA Cup and EFL Cup winners last term as well as Champions League finalists - risk falling short on multiple fronts this term.

But the German feels his side will be able to work out their problems, stating they must "go back to the basics" and that they cannot expect an immediate revival of fortunes.

"We realised after Napoli it was a real low point, and we had to change things quickly," he stated. "We didn't play Wolves, played Ajax, then didn't play Chelsea and couldn't keep up any momentum from the Ajax win."

"When you spot a problem and think you have the solution, you expect the solution to be instant and influential, that's never the case in football.

"When it doesn't work out, you realise step by step that you have to go back to the basics. We have to be patient again to do the right thing, and then we will be fine again."

Liverpool's mixed form has made it hard for new signing Darwin Nunez to have the desired impact after an early season red card, but Klopp is unconcerned over the forward's personal attributes.

"He is still adapting," he added. "New players come in and everybody talks about them and wants them to shine immediately and that happens from time to time.

"We had a long talk yesterday and we told him we are completely calm. It's really important in our situation that he isn't worrying. The three-game suspension didn't help him to settle, that's clear.

"The team isn't flying and that doesn't make it easier for a striker, especially a finisher. It's not that everything is clicking, that is not our situation at the moment."

Dan Campbell vowed to "look at everything" after the Detroit Lions' defense produced a miserable performance in a 48-45 loss to the Seattle Seahawks.

While few anticipated the Lions to emerge as contenders in Campbell's second season as head coach, there were expectations of a significant upturn after a talent-poor team stayed competitive throughout 2021, a campaign that was followed by a strong offseason.

Yet such expectations look misplaced after a 1-3 start in which the Lions have scored an NFL-high 140 points but conceded 141, also more than any other team in the league. They are the first team in NFL history to have scored and conceded at least 140 points in their opening four games.

The Seahawks and Lions combined for 93 points and 1,075 total yards of offense (Seattle – 555 yards; Detroit – 520 yards). It marked the second game in NFL history in which two teams combined for at least 90 points and 1,075 total yards of offense, joining the Cincinnati Bengals at the Cleveland Browns in Week 2 of the 2007 season. 

The Lions allowed 10.7 yards per pass play and 7.1 yards per rush in a game in which Seattle converted nine of their 12 third downs.

Campbell showed last season he is not afraid to make mid-season coaching changes, taking over play-calling duties from then offensive coordinator Anthony Lynn after an 0-8 start in 2021.

But he defended defensive coordinator Aaron Glenn despite that unit's ineptitude seeing a sensational offensive performance go to waste.

"I just don't feel our swagger," Campbell said. "I mean, we knew if we could get this team in second-and-long that would go a long way and then, we would — you would need to produce because it's been an area where that team has not been as good. And boy, we didn't make the most of it.

"Now look, they got us in a couple of third downs there late, third-and-longs that we have not been exposed to yet. And they gutted us. They got us good. And it was good designs by them, good play designs and in critical moments, they — it was good. It was real good by them.

"I've got a lot of faith in Aaron Glenn," Campbell said. "I've got a ton of faith in those assistants, and I think it's just — I think we sit down and I think we look at everything together.

"Because really, I think more than anything maybe it's time for a deep dive, a real deep dive into it. Players, everything that we're doing, but I also trust what he's doing.

"And there's a reason why I hired him, and so I want to let him do his job. But certainly, I'm going — I mean, I've got to look a lot deeper than I have."

Arsenal defender William Saliba has revealed he is in talks over a new contract at the Emirates Stadium after making a fine start to the season.

Having returned from a loan spell at Marseille ahead of the 2022-23 campaign, Saliba has started all eight of Arsenal's Premier League games this season, seven of which have ended in victory.

Saliba has formed a fearsome defensive partnership with Gabriel Magalhaes during Arsenal's best start to a Premier League campaign since 2007-08 – when they went on to finish third after taking 22 points from their first eight matches.

The France international's current deal runs until 2024, and he is hopeful of reaching an agreement to extend his stay.

Asked whether he could agree fresh terms after impressing in Saturday's 3-1 derby win over Tottenham, Saliba said: "Yeah, we will see. They [the club and his representatives] talk a little bit."

Saliba believes Arsenal are growing in confidence with each victory, adding: "You have to wait every time and I waited a long time for my first North London Derby. I enjoyed it from the first minute to the end, and now I am so happy. 

"We are so happy to win at home against Tottenham. It was a hard game, but we were focused all the game. We deserve this win.

"We play against the best players in the world. It is good for young players like me, and I learn a lot.

"The more we win, the more we are confident. We want every week to win, to win, to win — and that's it."

Arsenal goalkeeper Aaron Ramsdale has watched Saliba's development from close quarters in the season's early weeks, and has described him as a "Rolls-Royce" of a defender. 

"He has fit in really well," Ramsdale said. "It is a credit to him that he has been put straight into the team. He is a bit of a Rolls-Royce with the way he moves, and he has never seemed fazed.

"He is still a young boy so still makes mistakes, so at the minute it is either Ben [White], myself, Gabriel or Thomas Partey digging him out and he is digging other people out as well.

"That is the main thing at the minute, our mistakes aren't leading to too many things and that is the sign of a team who have good characters in and around that back five."

Carlo Ancelotti believes Real Madrid "deserved" to beat Osasuna in Sunday's draw, but called for a reaction from his players as he defended his decision to keep Eden Hazard benched.

The Belgium international was a spectator as Los Blancos slipped to a 1-1 draw against their visitors, with Karim Benzema fluffing a potential match-winning penalty to ensure the spoils were shared.

The club's first dropped points of the domestic season saw them surrender top spot to rivals Barcelona, with the pair's Clasico encounter – which takes place in just under a fortnight – set to represent a huge moment in the title race.

Speaking after Sunday's stalemate, Ancelotti acknowledged his team's frustrations after they dominated for long periods, but added that he anticipates a response.

"This team is upset when it doesn't win," he stated. "The game was under our control and we deserved to win. 

"We're not happy and that's the reason why this side won a lot last year. We're not happy with the draw and we will react soon. 

"We shouldn't be making excuses about the [international] break. We need to manage the break. We've got a very good squad."

Mariano Diaz was preferred to Hazard when Ancelotti required attacking reinforcements in the second half, and the Italian was succinct in his reasoning for the Belgian's absence.

"It was a game that needed a strong centre forward who was good in the air like Mariano, who had chances to score with his head," he added. "It wasn't the right match for Hazard’s qualities."

Meanwhile, Thibaut Courtois missed the game through a case of sciatica, but Ancelotti is hopeful he could return as soon as the club's midweek Champions League encounter with Shakhtar Donetsk.

"He's got some tests and we'll see if he can get back," he stated. "It's a muscular issue, I think it's with the sciatic nerve. We'll find out if he can play on Wednesday."

Erling Haaland shares many of the same qualities as Cristiano Ronaldo and Zlatan Ibrahimovic, according to Peter Schmeichel, who has described the Manchester City man as several top strikers "put into one player".

Haaland produced an incredible display as City swatted aside Manchester United for a 6-3 derby win on Sunday, scoring a treble and teeing up two goals for fellow hat-trick hero Phil Foden.

The Norwegian – who has scored 14 goals in his first eight Premier League appearances – has now scored a hat-trick in three successive home league games, becoming the first player to do so in the competition's history.

After watching Haaland tear United apart at the Etihad Stadium, Schmeichel picked out similarities between the 22-year-old and several striking legends.

"The biggest part of a good striker is patience. I played against some of the best strikers, and when they go missing is when you really have to concentrate," the former United and City goalkeeper told BBC Radio 5 Live.

"The Cristiano Ronaldos, the Filippo Inzaghis of this world – they disappear then all of a sudden they get the chance.

"When you look at Haaland, you see different players. That Zlatan-like goal, and Ronaldo is in there too. You see top, top strikers in one.

"That is why he is so dangerous. He has the luxury of seeing many top strikers and they are all put into one player."

Haaland's dominant display on Sunday saw him become just the 25th player to record five goal involvements in a Premier League game – and the youngest to ever do so (22 years, 73 days).

In Haaland and team-mate Kevin De Bruyne, meanwhile, City have the highest goalscorer and top assist-maker in Europe's top five leagues this season (in all competitions).

Haaland has already found the net 17 times this season, with five of those strikes being laid on by De Bruyne, who has a total of 10 assists in 2022-23.

Carolina Panthers head coach Matt Rhule said a change at quarterback was "not right to speak on" after Baker Mayfield's struggles continued in a 26-16 defeat against the Arizona Cardinals.

Mayfield threw two interceptions in the loss, finishing with a season-low passer rating of 61.9 as the Panthers slipped to 1-3 for the season.

Under Mayfield's leadership, the Panthers have managed a league-low 262.3 yards per game this season, as well as recording the NFL's third-least passing yards per match.

When asked whether Mayfield's status as starter was at risk after the game, Rhule told reporters: "I'm going to refrain from anything big picture until tomorrow.

"At the end of the day, I'm on the headset, I see the things, I know that it's never just one person here, one person there, it's a lot of different things.

"I'll try to give you a really well thought-out answer after watching the tapes.

"All that being said, I believe that we can play better than that. I just feel like we have to expect more from all of us as an offense, and it starts with me first.

"Offensively, we have to score more points. So yeah, we have to get it corrected, but in terms of any one person, I just don't think it's right to speak on it right now."

Mayfield's likely replacement would be Sam Darnold, though he is yet to come back off injured reserve after suffering an ankle sprain in Carolina's preseason.

Darnold started at quarterback 11 times for the Panthers last season, going 4-7 after joining in a trade from the New York Jets.

New York Jets head coach Robert Saleh lauded returning quarterback Zach Wilson following Sunday's 24-20 win over the Pittsburgh Steelers.

The Jets looked set for a third loss of the season when Steelers rookie Kenny Pickett scored two rushing touchdowns to hand the hosts a 20-10 second-half lead in Pennsylvania.

However, the first-round draft pick threw three interceptions as the Jets had the last laugh, with Breece Hall sealing victory when he ran for a two-yard touchdown with 16 seconds remaining.

Wilson – featuring for the first time since he suffered a knee injury in the Jets' preseason opener – was crucial to their revival, completing 10 of his 12 passes for 128 yards and a touchdown in a brilliant fourth quarter.

Speaking after the win, Saleh hailed Wilson's ability to handle pressure, declaring: "Zach doesn't flinch.

"I'm sure there were a couple of plays he wishes he had back. But he got us out of a lot of bad situations with his mobility. I thought he played a pretty good game, [for] his first game back."

Wilson himself, meanwhile, was delighted by the Jets' late show, adding: "All the ups and downs of trying to overcome adversity, it was just such a good win.

"I think there was so much growth those last two minutes as an offense, executing a drive as clean as it was and punching it in. It was just awesome

"It's just the NFL, man. We had some good things early, we scored, then things got stalled out. 

"My mentality is just keep doing my job, keep chipping away. That was my message and that's what everybody did. 

"There was some frustration, but it was the right frustration. That was a cool opportunity for us to lose a lead like that and come all the way back for the win."

Asked whether he was convinced the Jets would get over the line on their decisive late drive, Wilson added: "Yeah, 100 per cent from the beginning. 

"I think there was no doubt in our minds, especially when I hit a couple of quick passes, we hit a couple of runs as an offense. You could just feel it."

Pittsburgh Steelers head coach Mike Tomlin refused to commit to starting Kenny Pickett in Week 5 after the first-round draft pick made his NFL debut in their 24-20 loss to the New York Jets.

After a first half in which the Steelers only managed a pair of field goals, Tomlin introduced the 24-year-old quarterback, who ran in for two rushing touchdowns to hand Pittsburgh a 20-10 lead.

However, Pickett also threw three interceptions as the Jets hit back, and rookie Breece Hall's game-winning touchdown reduced the Steelers to 1-3 for the season.

Pickett's introduction came as something of a surprise after Tomlin appeared to rule out a change at quarterback following the Week 3 loss to the Cleveland Browns, and he refused to give away his future plans after Sunday's game.

"I'm not going to talk extended as we sit here," said Tomlin. "We did what we needed to do to put ourselves in a position to win this game. We'll do it again. 

"But I like to just keep it where we are in terms of what transpired here today. We'll deal with next week, next week."

Asked why he brought Pickett in, Tomlin added: "We just thought we needed a spark. 

"We didn't do much in the first half, not enough offensively and thought he could provide a spark for us.

"I thought he did some good things. I thought there was some energy there. We scored some touchdowns. But obviously we also turned the ball over.

"We're disappointed, but what transpired is not anything mystical. That's what we talked about as a collective in there. 

"No disrespect to the Jets. They made plays and won the football game. But it's not about who we play.

"It's not about rabbits' foots and so forth. We've got to play better. We've got to put them in a better position. We've got to perform better. And I'm talking about the collection of players and coaches in there."

Pickett, meanwhile, fronted up for Pittsburgh's defeat as he echoed Tomlin's call for improvements, saying: "I'm just disappointed. 

"[I] wanted to come in and get the win so that's really just the emotion, just disappointed we didn't come out with the outcome we worked so hard for. Definitely something we need to learn from and move on.

"The plays were there, we made plays, but the turnovers killed us. It's definitely on me and I have to improve."
