The Queen has led the messages of congratulations for British teenager Emma Raducanu following her "remarkable" history-making US Open triumph on Saturday.

The 18-year-old became the first-ever female or male qualifier to win a major tournament, triumphing 6-4 6-3 over fellow debutant finalist Leylah Fernandez at Flushing Meadows.

Raducanu did not drop a set throughout the tournament on her way to victory in only her second career grand slam after reaching the fourth round at Wimbledon earlier this year.

The achievement by Raducanu, who is the youngest women's grand slam finalist since a 17-year-old Maria Sharapova won at Wimbledon in 2004, was labeled as "remarkable" by the Queen.

"I send my congratulations to you on your success in winning the United States Open Tennis Championships," the Queen's message to Raducanu said. 

"It is a remarkable achievement at such a young age, and is testament to your hard work and dedication. 

"I have no doubt your outstanding performance, and that of your opponent Leylah Fernandez, will inspire the next generation of tennis players.  I send my warmest good wishes to you and your many supporters."

The Duke and Duchess of Cambridge also offered their congratulations along with United Kingdom Prime Minister Boris Johnson who praised the British sensation on social media.

"You showed extraordinary skill, poise and guts and we are all hugely proud of you," Mr Johnson wrote.

There were further tributes on social media coming from musicians Liam Gallagher and the Spice Girls, as well as football identities Marcus Rashford and Gary Lineker.

Emma Raducanu believes her shock US Open triumph highlights just how strong women's tennis is after winning Saturday's final against Leylah Fernandez ​in straight sets to become the first qualifier in history to win a grand slam.

The 18-year-old, ranked 150 by the WTA before beginning her tournament in New York some three weeks ago, prevailed 6-4 6-3 against fellow debutant finalist Fernandez.

Victory in Saturday's final caps a remarkable and life-changing couple of months for Raducanu, who also reached the last 16 of Wimbledon before pulling out of the competition due to medical reasons.

Raducanu is the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 and she feels the women's game is in strong hands.
​
"First of all, I really want to congratulate Leylah and her team – she played some incredible tennis and has beaten some of the top players in the world," Raducanu said in her on-court interview as she was handed the trophy by the legendary Billie Jean King.

"The level was extremely high and I hope we play each other in many more tournaments and hopefully finals.

"It shows the future of women's tennis and depth of the game is so great, every player in the draw has a shot at winning any tournament. 

"I hope the next generation can follow in the steps of some of the legends, for example Billie Jean right here."

Raducanu did not drop a set in her remarkable run at Flushing Meadows as she became the first British female to win a major tournament since Virginia Wade on home soil at Wimbledon 44 years ago.

Wade was in attendance for the final at Arthur Ashe Stadium – as was Tim Henman – and Raducanu will now be out to match or indeed better the success of the three-time grand slam winner.

"It means so much to have Virginia here and also Tim , British icons and for me to follow in their footsteps... it gave me the belief I could do it."

Raducanu proved too strong for world number 73 Fernandez with a perfect mix of power and precision that saw her hit 22 winners to her opponent's 18.

Only twice did Fernandez break Raducanu and the British teenager won 67 per cent of points behind her first serve.

"Leylah is always going to play great tennis and fight, that is why she is in the final, I knew I would have to dig deep," Raducanu said.

"As for this three weeks in New York, I would say having such a supportive team, the LTA my agent, and everyone back home watching on TV, thank you so much for your support over the years.

"Thank you for making me feel so at home from my first qualifying match, you have spurred me on in some difficult moments and I hope me and Leylah put on a good match today."

Emma Raducanu and Leylah Fernandez had the biggest moments of their careers – their lives, surely – coming up in a matter of moments, but both of the teenage sensations seemed calm and collected as they fulfilled some final media duties prior to heading out onto court at Arthur Ashe Stadium.

"I can't wait to get stuck in," said Raducanu, the first qualifier in history to reach a grand slam final. "I think we're just going to go out there and have fun," said Fernandez, vanquisher of US Open champions past over the course of the last two weeks.

Those questions were preceded by a commemoration of an event that occurred in New York 20 years ago to the day, the players waiting in the tunnel as tributes were paid to the lives lost on September 11, 2001, when the towers fell and the world changed.

Neither Fernandez nor Raducanu were born. Indeed, the latter does not turn 19 until November, and her opponent celebrated her 19th on Monday, a day before beating Elina Svitolina in the quarter-finals.

Whether down to youthful exuberance, or the fearlessness that inexperience can bring, both players – who last met in the second round of the juniors at Wimbledon in 2018 – lived up to their promises in the pre-match interviews, to the benefit of an audience that can only have been glued to whatever screen they watched on, not to mention the 23,000-strong crowd in attendance at Flushing Meadows.

It was a final that could have gone either way, yet ultimately in the moments it really mattered most, it was Raducanu who came out on top, a 6-4 6-3 victory sealing one of the most unlikely successes of all time.

The tone was set immediately in the first women's slam final between two unseeded players. Raducanu applying pressure and breaking serve to edge ahead.

But Fernandez has had to battle back against the odds throughout her incredible run, beating defending champion Naomi Osaka, former world number one Angelique Kerber and current number two Aryna Sabalenka. The scores were level two games later.

Raducanu had not dropped a set throughout her run, but at 30-0 down in the fifth game, it appeared to be swinging in Fernandez's favour. Four straight points from the Briton ensured that was not the case.

Special tennis was on show. Quality, control and poise worthy of players way beyond their years. After an hour, something had to give, and it was Raducanu who, at the fourth time of asking, broke serve to seal the set.

What did Fernandez have left? Was this the beginning of the end for the youngest player to beat more than one top-five opponent at the same slam since Serena Williams saw off Monica Seles, Lindsay Devenport and Martina Hingis in 1999?

Yet Raducanu found herself 2-1 and a break down three games into set two.

Fernandez could not capitalise and Raducanu returned from an 82 mile-an-hour serve to get back on the front foot. An exquisite forehand winner saw her break for 4-2.

Raducanu's Wimbledon came to an end in tears at the fourth-round stage. When she moved to within a game of grand slam immortality, there was hardly a flicker of emotion.

Fernandez said she was out to have fun, though, and a smile was back on her face as two championship points went begging for Raducanu, who then skidded across the baseline, cutting open her knee in the process.

A medical time out was required and Fernandez's joy turned to frustration. It might have been crucial, Raducanu saving two break points before an outstanding ace secured her place in history.

Ten matches, no sets dropped – Williams was the last player, in 2014, to win the US Open without dropping a set. Raducanu is also now the first woman to win a title so early in her slam career, in just her second major appearance. 

Nine years and one day since Andy Murray won his first major on the same court, a new British hero emerged.

Virginia Wade, the last British woman to reach the Flushing Meadows final in the Open Era and the 1968 champion, watched on as the iconic Billie Jean King handed the trophy over to a superstar in the making.

Big names were absent from Flushing Meadows this year, but Raducanu and Fernandez served up a final, and a result, for the ages.

Emma Raducanu became the first qualifier in tennis history to win a grand slam final after beating Leylah Fernandez 6-4 6-3 in the US Open final on Saturday.

Eighteen-year-old Raducanu, who was ranked 150 by the WTA before the tournament and had only played in one other major (Wimbledon earlier this year), enjoyed a sensational run at Flushing Meadows and proved too strong for Fernandez, 19, who was also contesting her first grand slam final.

Briton Raducanu – the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 – showed no signs of nerves in the opening set, taking a decisive advantage.

A roller-coaster second set could have gone either way, but from a break down, Raducanu hit back to serve out the victory in an epic final between two of tennis' rising stars.

Neither player looked fazed by the magnitude of the occasion during the first set, with a series of high-quality rallies and superb winners lighting up Arthur Ashe Stadium.

Raducanu started strongly and went 2-0 up after a pulsating game on Fernandez’s serve, which lasted more than 10 minutes and had seen the Canadian save five break points before eventually succumbing.

Fernandez responded well, though, breaking back immediately before restoring parity on her own serve.

The first set went with serve until Fernandez was serving to stay in it at 5-4 down.

Raducanu squandered three set points before ultimately taking her fourth with a thumping forehand down the line, securing the lead after exactly one hour.

The British player had three break points in the second game of the second set, but Fernandez rallied to hold.

That recovery galvanised Fernandez, who broke Raducanu in the next game at the third time of asking, although her opponent broke back immediately with two wonderful backhands to see out the game.

Raducanu held her serve before opening up a 4-2 lead as Fernandez wilted under a string of excellent shots.

After a dramatic medical time out at 30-40 down on her own serve for a cut below her left knee, which left Fernandez visibly frustrated, Raducanu came back out renewed and served an ace to seal arguably the most unlikely grand slam win of all time.

Lewis Hamilton has predicted an "easy win" for championship rival Max Verstappen in Sunday's Italian Grand Prix and is focused only on trying to "limit the damage" caused by his disappointing showing in the sprint race.

Mercedes driver Hamilton was made to pay for a poor launch in Saturday's half-hour 18-lap race as he slipped from second down to fifth, behind Lando Norris, Daniel Ricciardo, Verstappen and winner Valtteri Bottas.

With Verstappen starting from the back of the grid on Sunday after taking a penalty for a power unit change, each driver moves up a place, meaning Hamilton will start in fourth and Verstappen in pole position.

Victory in the sprint race – just the second to have ever been staged after the inaugural event at Silverstone in July – also meant Red Bull's Verstappen extended his championship lead over Hamilton from three points to five.

And seven-time world champion Hamilton fears that gap could grow wider come the end of the main event in Italy, with the Briton's main aim being to finish ahead of McLaren pair Ricciardo and Norris in second place.

"We lost a lot of points," he told Sky Sports. "I've got to try and figure out how I can get by the McLarens tomorrow, and try to limit the damage. 

"It's not the outcome we wanted and we can't afford days like these, especially when it is this close in the championship.

"You saw the pace of the Red Bull. I don't know if Max was quicker than Valtteri but they're so fast, and now he's on pole, so it should be an easy win for him."

Verstappen was considered an outsider for the sprint but comfortably finished in second, though the Dutchman is taking nothing for granted heading into Sunday's race.

"I expected we would lose points on Saturday, but I have increased the lead a little," he told De Telegraaf. "Every little bit helps, of course. But it can also quickly turn around. I know all about that.

"I don't expect it to be a straightforward and easy race – Valtteri coming from the back, Lewis P4, they have a lot of pace, so we'll see what we can do against them."

Bottas' triumph came in the same week it was confirmed he will switch from Mercedes to Alfa Romeo next year, having been dropped in favour of George Russell.

The Finn also led the way in the traditional qualifying session on Friday and his sprint race victory never looked in doubt as he retained first place throughout.

With the elation of finishing first comes some disappointment for Bottas, however, as he always knew he would be starting the main event from the back of the grid due to Mercedes' decision to add a number of new power unit elements to his car.
 
"What can I say, it's been a perfect weekend so far and now I have a grid penalty," he said. "That happens, but it's good to see we have good speed from the car here, good pace, and I'll be fighting tomorrow, going as high as I can.

"For sure it's annoying. We've done good the last two days, with good performances and then you kind of reset completely for the day after and you start from the back.

"Those are things that are out of my hands, so I won't waste too much energy or be too negative about it because there's absolutely nothing I can do about it.

"The only thing I can do is try my best and go full gas tomorrow. At least I got a few points – every point counts for me personally and for us as a team."

Antoine Griezmann was eager to return to Atletico Madrid, according to Diego Simeone, who acknowledged there will be plenty of expectation on the forward.

Griezmann left Atleti for Barcelona in 2019 but, on deadline day, the 30-year-old returned to the Spanish champions on a season-long loan with an option to extend the deal.

With Barca hit by huge financial losses, the Catalan club needed to get Griezmann's wages off their books, even with Lionel Messi having left for Paris Saint-Germain.

Griezmann's departure from Atleti two years ago was by no means a smooth one, with supporters seemingly aggravated by the prolonged nature of the move. In 2018, the former Real Socieded attacker committed his future to the club, only to leave a season later.

However, Simeone insists Griezmann, who scored 94 LaLiga goals for Atleti in his first spell, was determined to return from Barca.

"I found a Griezmann who was eager to return," Simeone said ahead of Sunday's meeting with Espanyol, with Griezmann having been included in Atleti's squad for an immediate return to the city of Barcelona.

"[He was] enthusiastic about the option of returning to the team, and people will demand from Griezmann what they demand from us every day.

"The fans are very demanding and it is normal for them to demand from Griezmann what they demand from us every day."

Griezmann has joined a sparkling attack at Atleti, with Luis Suarez, Joao Felix and Angel Correa likely to be competing with the World Cup winner for a place up front. 

"Actually, when you talk about a better or worse squad, short or deep, everything is seen as a consequence of what is going to happen during the season," said Simeone when asked if his team were favourites for the title.

"It is easy to think of the best before the game starts and for there to be some imagination about the names, but the names do not make a team. The men do that.

"So, we will go without changing anything, with the commitment that I have with the club, and tomorrow we will play against a very complex, aggressive opponent who will be tough, like everyone else in the Spanish league.

"We hope to improve compared to what happened last season. We did not have a good Copa del Rey [run], in the Champions League we would have liked to compete better [and] we [also] have the Supercopa de Espana.

"Four competitions where hopefully we can improve the numbers from last season, as we are always looking to do."

Massimiliano Allegri has full faith in his Juventus squad turning around their campaign and challenging for the Serie A title after falling to a 2-1 loss at Napoli.

Juve's slow start to Allegri's second spell in charge continued on Saturday as second-half goals from Matteo Politano and Kalidou Koulibaly earned Napoli a comeback win.

The Bianconeri, who led through Alvaro Morata's 10th-minute strike, have now failed to win any of their first three league games for just the second time in 52 Serie A seasons.

Saturday's late loss also means Allegri has failed to win any of his past eight league games in charge of Juve either side of a two-year sabbatical.

After collecting just one point from their first three matches of the 2021-22 campaign, six-time Scudetto winner Allegri is adamant that his side will grow stronger.

"I have ample trust in this group. I know they will make up the lost ground," he said. "This group is destined to grow thanks to the blows taken.

"This evening's defeat was different and we must quickly put it behind us."

After profiting from a Kostas Manolas error to take the lead in Naples, Juve themselves gifted their opponents – who now have three wins from three – a couple of goals.

Wojciech Szczesny parried Lorenzo Insigne's shot into the path of Politano for Napoli's leveller and could only push a poor Moise Kean header straight to Koulibaly for the late winner.

It is the first time since March 2010 that Napoli have recovered from a losing position to beat Juventus in the league and Allegri accepts his side were not good enough.

"I liked the attitude of the team in the first half, but in the second half Napoli got the upper hand. Sometimes you are made to pay for individual mistakes," he said.

"Szczesny does not lack calmness. He made a mistake with his handling today, but he will be in the team on Tuesday.

"As for Kean, these things happen in football sometimes. We also conceded similar goals to Udinese and Empoli

"From a technical point of view, we could have done better. We haven't won yet, but now we start thinking about our next match in the Champions League."

That European tie with Malmo on Tuesday is followed five days later by a huge clash with Allegri's former side Milan at the Allianz Stadium.

"We know that we need to be more lucid near the area, though the team did what I asked of them today from a tactical point of view against a good Napoli side," Allegri added.

"In football there is no room for mistakes. We have an important test ahead of us that we must overcome in order for it not to become a mental thing."

Juve, who were missing some key players on Saturday, managed just eight shots in total against Napoli and none at all on target in the second half.

That makes it back-to-back blanks for the Bianconeri since Cristiano Ronaldo left the club to rejoin Manchester United, but Allegri reiterated he is eager to move on from that high-profile exit.

"Ronaldo is part of the past, he made a choice," Allegri said. "Now he's gone. Juve let him go because you can't keep a player against your will."

Francesco Bagnaia produced a "perfect lap" to seal pole position for Sunday's Aragon GP.

The Italian delivered a lap of one minute and 46.332 seconds on his second run to break the lap record at Aragon, which had stood since 2015.

Ducati team-mate Jack Miller was his nearest rival at just 0.366secs adrift, giving Ducati their first one-two in qualifying since Aragon 2018.

It marks Bagnaia's second pole of the 2021 season and the 50th for Ducati in MotoGP.

"I think it was a perfect lap," said Bagnaia. "It was great. I did a nice sector one, the sector two was incredible too and our bike in sector four helped us a lot.

"Also, entry to the last corner was incredible. I looked at the data of Jorge Martin this morning, who was doing a different line compared to me, and then I tried to do the same and I improved a lot. I didn't expect to do a lap like that."

Bagnaia has never won a MotoGP race and he is keen to avoid complacency ahead of Sunday's race at MotorLand.

"I'll just try to set my pace and be fast," he added. "It will be important what happens with the tyres after 15 or 16 laps and in the last part of the race I feel strong, we will see if I am strong enough to win.

"The important thing will be to stay with the best from start to finish.

"It’s difficult to say that I'm ready to win or that I can win, but all the things are there."

Fabio Quartararo completed the front row, extending his run of consecutive top-three qualifying results to 11 this season.

The French rider, however, does not believe he has the pace to keep up with the Ducati pair.

"I want to have fun. Of course, it would be great to fight for the podium," he said.

"But to be honest, I don't feel I have the pace, so I will try to manage the best result as possible and I will try to stay with the front guys and fight until the end.

"But right now, at least we need to make a step in the warm-up to be able to fight for the podium tomorrow.

"So, let's hope for an improvement on the warm-up."

British tennis was on a super Saturday high at the US Open as Emma Raducanu took centre stage – after Joe Salisbury, Gordon Reid and Alfie Hewett celebrated title success.

Salisbury completed a remarkable doubles double, adding the mixed title to the men's crown he secured on Friday, and Reid and Hewett teamed up to clinch a calendar Grand Slam in wheelchair men's doubles.

After Salisbury and American partner Rajeev Ram won the men's doubles title by beating Jamie Murray and Bruno Soares, Salisbury returned on Saturday to land another title, the fourth major of his career.

Salisbury teamed up with another American partner, Desirae Krawczyk, to see off Mexican Giuliana Olmos and Salvadorean Marcelo Arevalo 7-5 6-2 on Arthur Ashe Stadium, in the match directly before the women's final.

Raducanu, the world number 150, was going for glory in the women's singles final against another unlikely finalist in Canada's Leylah Fernandez.

If she was seeking inspiration from fellow Britons, it was in plentiful supply, with wheelchair maestros Reid and Hewett scoring a 6-2 6-1 doubles victory over Japan's Shingo Kunieda and Argentina's Gustavo Fernandez.

That meant they sealed a clean sweep of the Australian Open, French Open, Wimbledon and the US Open in 2021, becoming the first men's wheelchair duo in history to perform that feat.

France's Stephane Houdet previously won a calendar Grand Slam in the event, but he played with two different partners during the 2014 campaign, landing three titles with Kunieda and one with Joachim Gerard.

Robert Lewandowski was withdrawn during Bayern Munich's 4-1 win at RB Leipzig as a "precaution", though Serge Gnabry does appear to be a doubt to face Barcelona on Tuesday.

Julian Nagelsmann enjoyed a personally satisfying return to former club Leipzig on Saturday, as Bayern ran out comprehensive winners at the Red Bull Arena.

The coach was given a frosty reception at the start, with fans annoyed that he took several members of the coaching staff and Marcel Sabitzer to Bayern despite promising not to raid his former club.

Leipzig's social media team stoked the tension by poking fun at Nagelsmann and the situation before the game, posting a mocked-up image of Nagelsmann driving a car with his coaching staff, Sabitzer and Dayot Upamecano – who agreed a deal with Bayern before his boss arrived – present as passengers. "Remember, it's the away dressing room for you this time, guys," read the caption.

Nagelsmann had the last laugh as Bayern comprehensively left with all three points – Lewandowski's early penalty was added to by a Jamal Musiala volley, Leroy Sane's tap-in and a late Eric Maxim Choupo-Moting strike.

Musiala was ultimately the key man with a goal and an assist, but he was only on the pitch due to an injury suffered by Gnabry late in the first half, and Nagelsmann could not be sure he will be fit to face Barcelona in Tuesday's Champions League opener.

"With Serge there is something in his back, maybe lumbago [lower-back pain]," he told Sky. "I can’t make a prognosis for Tuesday just yet.

"He's already being treated by the medical staff and we'll have to see how he's doing tomorrow and what extent things are to know if he'll be back to work by Tuesday."

Lewandowski was also withdrawn later in the game once Nagelsmann was confident the contest was over.

It seems he too was struggling with an injury, though Nagelsmann was less concerned about the prolific striker's condition, adamant they planned to give him a bit of a rest towards the end anyway.

"It's like that with Lewy, he's had a few problems in the adductor area," Nagelsmann added.

"I don't think that's anything structural, at least the doctor told me that. It was just a precautionary measure.

"When it was quickly 3-0, we decided to switch him earlier so that he would just stay fit and healthy."

Mauricio Pochettino insisted Kylian Mbappe has plenty of love for Paris Saint-Germain after the speculation surrounding a move to Real Madrid last month.

PSG reportedly rejected three bids - the last one said to be worth up to €200million - from Madrid for the 22-year-old, whose contract with the Ligue 1 giants runs out at the end of the season.

Mbappe has so far turned down the opportunity to sign a new deal, though the speculation has not affected his form, and he scored with a typically composed finish in PSG's 4-0 rout of Clermont on Saturday.

The France forward has now scored against 26 of the 27 teams he has faced in Ligue 1, while he has also directly contributed to a goal in each of his last 10 appearances in the competition.

Mbappe, who was taken off with 11 minutes remaining, ended Saturday's match with a game-leading five attempts, with three of those on target, including a shot that was parried out to Idrissa Gueye for PSG's fourth goal.

However, prior to his strike against Clermont, there appeared to be something of a mixed reaction from the PSG faithful at Parc des Princes, with some sections of the home fans appearing to whistle and jeer the youngster.

Pochettino claimed not to have heard anything untoward, but was adamant that Mbappe has nothing but respect for PSG.

"I didn't hear the whistles, but I heard the ovation he received when he went to take a corner in the second half with the affection of all the supporters of Paris," Pochettino told a news conference.

"He is a great professional, a great player and a good boy, he has a lot of love for this club. He has shown it since he got here.

"He is focused on improving every day, helping the team and fulfilling the club's goals. He shows great respect every day for this club, you have to salute him."

Next up for PSG is a Champions League encounter with Club Brugge. Lionel Messi and Neymar, who were both absent for Saturday's match, are likely to return and may well start in a front three with Mbappe for the first time.

Julian Nagelsmann enjoyed a glorious return to former club RB Leipzig on Saturday as Bayern Munich ran out comfortable 4-1 victors in the Bundesliga.

Nagelsmann became a source of anger among Leipzig fans after he departed for Bayern and then also took Marcel Sabitzer with him, and any such ill-feeling will not have eased after this victory.

Robert Lewandowski put Bayern in front early on with a well-taken penalty and then a quick-fire double courtesy of Jamal Musiala and Leroy Sane early in the second half put the game beyond the hosts.

Jesse Marsch's men quickly pulled one back in spectacular fashion through Konrad Laimer, but it was not enough to inspire a comeback as Leipzig's miserable record against Bayern continued, Eric Maxim Choupo-Moting adding a stoppage-time fourth for good measure.

Leipzig had already seen a penalty shout of their own controversially ignored when Kevin Kampl was penalised for handball after a VAR check in the 12th minute, with Lewandowski sweeping home the resulting spot-kick.

The hosts grew as a threat as the first half progressed and Bayern received a blow just before half-time when Serge Gnabry was forced off.

But his replacement quickly made an impact just after the break, as Musiala volleyed home Alphonso Davies' cross.

The misery of Andre Silva's disallowed goal shortly after was compounded by Sane burying a Musiala cross to essentially end Leipzig's hopes of a turnaround.

They certainly showed spirit as Laimer got one back with a sumptuous long-range strike and Silva almost reached a Christopher Nkunku pass for a tap-in.

But it was Bayern who got the only late goal, Choupo-Moting showing good composure to slam past Peter Gulacsi after Kimmich sliced open the Leipzig defence.

Juventus' slow start to life under Massimiliano Allegri continued on Saturday as second-half goals from Matteo Politano and Kalidou Koulibaly saw them lose 2-1 at Napoli.

After being held by Udinese before suffering a shock home defeat to Empoli, it looked like being third time lucky for Allegri in his second spell in charge as Alvaro Morata profited from a terrible Kostas Manolas error to open the scoring early on.

But Napoli responded through a Politano strike shortly before the hour mark after Wojciech Szczesny pushed the ball into the forward's path, and the hosts completed the comeback thanks to Koulibaly's finish five minutes from time.

It is just the second time in 51 Serie A campaigns – the other occasion being in Allegri's first tenure in 2015-16 –  that Juventus have failed to win any of their first three games to a Serie A season.

Napoli started the match on top but found themselves behind against the run of play when Morata caught Manolas in possession and beat David Ospina from a tight angle.

Dejan Kulusevski was denied by a fine Ospina save soon after, although the offside flag would have denied the forward, who was making his first start of the campaign.

Napoli showed good resolve to find an equaliser as a shot by Lorenzo Insigne, making his 400th appearance for the club in all competitions, was parried by Szczesny and Politano reacted quickest to squeeze home.

The hosts always looked the more likely to find a winner in the remaining half an hour and so that proved when Moise Kean's poor defensive header was fumbled by Szczesny for Koulibaly to score from a yard out.
