Ravichandran Ashwin said he never envisaged bowling for his country when he was a teenager let alone taking more Test wickets in India than Harbhajan Singh after tormenting England on Sunday.

Ashwin took 5-43 on a dramatic day two in Chennai, where the tourists were bowled out for only 134 in reply to India's 329 all out.

Virat Kohli's side were 54-1 at stumps – leading by 249 runs – and well on course to level the four-match series.

Ashwin generated huge turn and bounce, with the spinner's drift also causing the England batsmen all sorts of trouble.

Only the great Anil Kumble (350) has more Test scalps than Ashwin in India after the 34-year-old moved past Harbhajan's total of 265.

Ashwin vividly recalls watching Harbhajan take 15 wickets in Chennai to secure a series win over Australia 20 years ago, and expressed his pride after bettering the Indian great's tally of scalps on home soil.

"When I watched the 2000-01 series, when Bhajju Pa [Harbhajan] played, I didn't even imagine I would go on to become an off-spinner for my country," Ashwin said.

"I was still a batsman for my state. Trying to accelerate towards batting and playing for my country. I wasn't even sure I would go on to become a player for the Indian team.

"Lots of my team-mates from that age, from that generation, used to make fun of me because in my action I used to try to bowl like Bhajju Pa.

"From there on to come on and go past him has to be incredibly special. I didn't know of it. Now that I know of it, I am incredibly happy. Sorry, Bhajju Pa."

Ashwin put England under huge pressure in such tough conditions as he took his 29th five-wicket Test haul – putting him level with Glenn McGrath in seventh on the all-time list.

The wily Ashwin has now claimed the wickets of 200 left-handers in the longest format, a landmark he reached by bowling Stuart Broad.

Novak Djokovic fought into the quarter-finals of the Australian Open despite concerns over a muscle injury, seeing off Milos Raonic in four sets.

Djokovic's hopes of defending his title appeared to be in doubt when he said he had a "muscle tear" and was unsure whether he would play the fourth-round clash.

But his history of dominance over Raonic was perhaps a motivating factor in him taking to the court and he stretched his head to head lead to 12-0 with his 300th grand slam win, becoming only the second player in history to reach the landmark.

He did not have it all his own way, a spirited Raonic levelling matters in the second set after losing the first on a tie-break.

However, Djokovic was in control thereafter, progressing 7-6 (7-4) 4-6 6-1 6-4, though a last-eight meeting with Alexander Zverev may prove a sterner test.

Djokovic made it eight wins in nine in tie-breaks with Raonic to take the first set and things looked bleak for the Canadian when he received treatment on his foot in the second set.

But that break proved just the tonic for Raonic as he went on to win a set against Djokovic for the first time in four grand slam meetings.

Yet the tide turned emphatically back in Djokovic's favour in the third – the Serbian winning five straight games to move into a 2-1 lead.

His success came through a familiar strategy against a player of Raonic's power on serve.

Djokovic wasted few opportunities to punish the second serve and consistently took Raonic out of his comfort zone by forcing him into long rallies.

Raonic, to his credit, did save four break points in the fourth set but the dam finally burst and he could not prevent Djokovic from snatching the fifth chance that came his way, the world number one ensuring there was to be no shock as he reached another milestone in a remarkable career.

Data Slam: Djokovic's delightful dozen

Djokovic is through to a 12th quarter-final in Melbourne, the eight-time winner last failing to reach the stage in 2018, when he lost to Hyeon Chung.

WINNERS/UNFORCED ERRORS
Djokovic – 41/25
Raonic – 50/35

ACES/DOUBLE FAULTS
Djokovic – 10/3
Raonic – 26/3

BREAK POINTS WON
Djokovic – 3/11
Raonic – 1/3

Central Coast Mariners extended their lead at the top of the A-League thanks to a 2-0 win at 10-man Wellington Phoenix.

The hosts operated with reduced numbers for more than an hour of the contest after David Ball was given a deserved straight red card for a reckless lunge on Matt Simon.

Simon recovered well enough to give Central Coast the lead five minutes before half-time, clipping home Marco Urena's excellent throughball.

The goalscorer heaped praise on the experienced Costa Rica playmaker afterwards.

"You can see Marco's quality out on the pitch and that pass was just another showing from him of how good he is," Simon said.

"And he's only going to get better.  I think he's still got a little bit to go to get 100 per cent fit but I think he's shown his qualities so far."

Oliver Bozanic made it 2-0 from the penalty spot after another misguided Phoenix challenge - this time from Te Atawhai Hudson-Wihongi on Daniel De Silva - and there was little doubt from that point that the Mariners would open up a four-point gap over second-placed Macarthur.

Brisbane Roar had the chance to leapfrog the Sydney club but were held to a 0-0 draw at home to Newcastle Jets.

The Jets are seventh with two wins from eight games so far, with Valentino Yuel close to a being a topical matchwinner on Sunday when his 25-yard drive boomed back off the post.

Wellington are only kept off the bottom by Melbourne Victory on goal difference, although they have only played six times.

Simona Halep set up a quarter-final duel with Serena Williams after showing admirable character to battle back from a set down to beat Iga Swiatek 3-6 6-1 6-4 and seal her 100th grand slam match win.

Halep and Swiatek put on a thrilling show in the night session on Sunday, as the Romanian two-time grand slam champion demonstrated her fighting spirit to come from a set down and reach the last eight.

Swiatek took charge in the first set after saving the first two break points of the contest, eventually putting herself in a commanding position as she won the 10 of the final 11 points of the set, but Halep remained focused as her 19-year-old opponent began to wobble in the second.

Halep then snuffed out any threat of a turnaround by breaking back straight after losing on her own service in the decider and she went on to set up a meeting with Williams, who had overpowered Aryna Sabalenka earlier in the day.

Naomi Osaka also advanced, though she was by no means comfortable, while Hsieh Su-wei beat Marketa Vondrousova in straight sets.

HALEP'S REVENGE

Halep's clash with Swiatek was their first since the French Open last October, when Swiatek ran out a 6-1 6-2 winner and went on to claim her maiden major title.

Revenge was on the cards at Melbourne Park and Halep got the job done impressively, showing her mettle to return from a set down.

"Well, I thought before the match that I have to be a little bit more aggressive than Paris. In Paris I have been very far back, and my ball didn't go through the court," the second seed said. "So, I thought that it's a better chance to go and hit.

"The pressure came from the way I played the last match against her. I just expected a better game from myself, which I did, and I'm really happy about that."

Halep accepts facing Williams will be an entirely different challenge, but she remains confident despite lauding the American a "legend" in her on-court interview.

"Of course it's different, she's the only one with 23 grand slams, so you cannot compare Serena with all of us, because we do not have so many grand slams," Halep added.

"But when I step on the court, it's just another opponent, and always I'm focused on myself more than I focus on who I play. We played so many times. I know what to expect. I will just try to do my game, and I will be confident."

WILLIAMS ON COURSE

All eyes are on Williams yet again, as she hopes to equal Margaret Court's record of 24 grand slam titles – and on the evidence of her latest win, she will take some stopping as she won 6-4 2-6 6-4.

Williams revealed she had to cope with a little off-court stress this week with her clothing line, and Sabalenka certainly kept the pressure up as the 22-year-old took the second set.

But Williams responded well to the seventh seed, who became the first player to take a set off the former world number one. Williams said she remained confident despite that setback.

"Like I said on the court, I just felt like even games that I lost, I was so close to winning. Not all games, but probably most of those games," she said. "I just needed to play better on the big points.  I knew that I could. I still hadn't reached my peak. I was like, 'Okay, Serena, you got this, just keep going.'"

OSAKA RELEASES HER ANGER

Osaka was in a real spot of bother against Garbine Muguruza, but saved two match points.

The 2019 champion Osaka steadied herself and felt more composed after a brief show of frustration, as she struck the ground with her racquet.

Ultimately, she emerged a 4-6 6-4 7-5 victor, and Osaka felt letting frustration get the better of her for a moment helped her cause.

"On the first match point, I was just thinking that I didn't hit a decent serve that entire game, so I should really focus on my serve," he said. "I feel like my serve stats were pretty good that set, so I was just telling myself to do better.

"Then on the second point, when the rally started, I just told myself not to push [the ball] but also don't do something crazy and make a really bad unforced error. I felt the entire match I was overthinking. There was a moment when I got angry and hit my racquet on the ground. I feel like I released a lot of the thoughts that I had. It just made me go more into instinct-based tennis."

She will face Hsieh next, the world number 71 having beaten Vondrousova – ranked 51 places higher – 6-4 6-2.

Ravichandran Ashwin claimed his second successive five-wicket haul as India skittled England out cheaply on day two to put themselves in total command of the second Test.

Fifteen wickets tumbled on what look more like a final-day pitch at M. A. Chidambaram Stadium on Sunday, with Moeen Ali (4-128) and Olly Stone both striking twice to bowl India out for 329.

The tourists, leading the four-match series 1-0, were dismissed for only 134 in reply, giving India a first-innings lead of 195 runs in Chennai.

Jack Leach got rid of Shubman Gill but first-innings centurion Rohit Sharma was unbeaten on 25 at stumps, with in complete control on 54-1 - leading by 249 runs.

Ashwin followed up his six-wicket haul in the second innings of the first Test by taking 5-43 in a brilliant exhibition of spin bowling in dream conditions for the spinner, who generated sharp turn and bounce.

Ishant Sharma (2-22) trapped Rory Burns leg before without scoring and Dom Sibley fell for 16 after India added only 29 runs to their overnight total of 300-6.

Debutant Axar Patel (2-40) claimed the huge scalp of in-form England captain Joe Root, caught by Ashwin at short fine leg for only six to become the spinner's first Test victim.

England were reeling on 39-4 after Ashwin got big turn and bounce to see the back of Dan Lawrence and there were more roars from a crowd of 10,000 when the wily tweaker bowled Ben Stokes (18) early in the afternoon session.

Ollie Pope made 22 before falling to Mohammed Siraj and although Ben Foakes (42 not out) played superbly against the spinners, England were all out from 59.5 overs when Stuart Broad was cleaned up by Ashwin.

Leach snared Gill lbw and Rohit successfully reviewed after he was given out in the same fashion but got an inside edge, while also possibly getting away with it when he padded up not offering a shot, but India are well on course to level the series.

Kevin Durant was grateful for the warm reception and tribute video upon his first return to the Golden State Warriors as he led the Brooklyn Nets to a 134-117 win on Saturday.

Durant spent three seasons with the Warriors, winning two NBA Championships and was named Finals MVP twice.

He was absent last season after undergoing surgery on a torn Achilles tendon in Game 5 of the 2019 NBA Finals, and then opted to leave as a free agent in July that year.

Saturday's contest was his first return to face the Warriors after sitting out 2019-20, and he went on to play an important role with 20 points, second only to Kyrie Irving (23) on the Nets' side.

Durant was impressed with the focus the Nets displayed, but he went on to revel in the tribute and reception afforded to him by his former team.

"We came out and played a great game," Durant said afterwards. "We were focused from this morning in shootaround, and it was a good vibe all day.

"The tribute video was cool. I think about those moments daily. Every single moment that I have had in this league, I think about it and try to analyse it and get better.

"My time here in Golden State was so much fun. It was such a big learning experience, especially learning basketball in a different philosophy. I'm going take to that with me for the rest of my life."

Warriors coach Steve Kerr was in charge throughout Durant's three-year spell in the Bay Area and felt the tribute video was the least they could do, and a similar acknowledgement will take place once fans are allowed back in attendance.

"This is something that is such a no-brainer," Kerr said. "When Kevin came here and gave us three years of just incredible basketball, the least we could do is welcome him back with open arms.

"He's a guy that gave everything to us for three years then left with a devastating injury. There should be a lot of love, he did so much for us.''

Victory leaves the Nets third in the Eastern Conference.

Serena Williams calmed injured fears after coming through a thrilling back-and-forth against Arnya Sabalenka to reach the quarter-finals of the Australian Open.

Williams, who is pursuing a record-equalling 24th career grand slam and her first major victory in four years, prevailed 6-4 2-6 6-4 after more than two hours on court against seventh seed Sabalenka.

Her struggles during the second set appeared partly attributable to a fall but Williams recovered her poise and the 39-year-old does not expect any ill-effects in a last-eight showdown against either Simona Halep or Iga Swiatek.

"I don't think so. It didn't hurt at all. I didn't roll my ankle, so that was good," she told reporters.

"Yeah, I think it was just dramatic, me being dramatic.

"My first thought was, 'Not another ankle sprain in Australia'. But I knew immediately that it wasn't.

"Then I was more embarrassed than anything. I was like, 'Oh, my goodness'."

Williams moved well throughout the contest, assuaging any lingering concerns over Achilles problems that have dogged her of late - even manging to rally when Sabalenka reeled off three consecutive games from 1-4 down in the decider.

"I've worked really hard on my movement. Yeah, I like retrieving balls. I mean, obviously I like to be on the offense, but I can play defence really well, as well.

"I do get a lot of balls back when I need to. I didn't think about my Achilles. It's so good to not think about it. Oh, my goodness. It's been a problem actually since 2018.

"I just never want that problem again. It feels really good to just play and to run, to not feel that. It's a great relief."

Arguably Williams' greatest inconvenience around the match was not a physical one, after she had to participate in a Saturday conference call to avert an "emergency" at her clothing business.

"Tennis is a lot less stressful. I don't have to manage a team. I do manage a team actually, but it's different," she chuckled. "Even though I am the CEO of my tennis team, it's definitely different.

"I think a part of me loves being on the court because it's free-flowing. It's not like I have to kind of just manage and make sure everyone is able to perform.

"I have a second career and it's fun. One of our main players, our employees, had an emergency. You got to step it up when you got to step it up.

"I was smart about that. I scheduled a call directly after my practice. I was like, 'Okay, I can do it early and still have the rest of the day to relax'.

"And it was during [Williams' daughter] Olympia's nap, so it was perfect."

Lazio can win Serie A's Scudetto race this season according to Christian Vieri, who lauded Simone Inzaghi's "amazing" team.

Spearheaded by highly rated head coach Inzaghi, talisman Ciro Immobile and star midfielder Sergej Milinkovic-Savic, Lazio are once again challenging in 2020-21.

Lazio can move to within six points of top spot with victory over second-placed Inter on Sunday as they prepare for a blockbuster Champions League last-16 tie against holders Bayern Munich.

Inzaghi has renewed Lazio's fortunes since taking charge in 2016, guiding the capital club to Coppa Italia (2019) and Supercoppa Italiana (2017 and 2019) success. The Biancocelesti had not celebrated silverware since 2013.

Ahead of the Inter showdown, Lazio have found the net in each of their past 17 Serie A games – they last went on a longer streak in October 1994 (18).

Lazio have also gained the most Serie A points in 2021 (19). They are the only unbeaten side (W6 D1) – having also conceded the fewest goals (four, level with Genoa) since the turn of the year.

Vieri spent a year with Lazio in 1998-99 – scoring 14 goals in 28 appearances under Sven-Goran Eriksson as the club won the UEFA Cup Winners' Cup and Supercoppa Italiana alongside Alessandro Nesta, Pavel Nedved, Marcelo Salas, Sinisa Mihajlovic and Dejan Stankovic before a then-record move to Inter – and he hailed the work of Inzaghi.

"He has been there for four years. You can't change coach every year," ex-Italy striker Vieri told Stats Perform News. "Coaches need time. All the teams that are changing every year aren't doing well.

"Lazio are doing amazing. They have an amazing director – [Igli] Tare, fantastic. They have big players at Lazio.

"Lazio are a fantastic team. They played amazing football. In the Champions League and qualified very easy.

"Lazio are there to win everything. Lazio can win the Scudetto, you never know. Let's see what happens in the Champions League. Anything can happen, but they're doing amazing."

Lazio have not won the Scudetto since 1999-2000 – Inzaghi was part of that triumphant team as a player – but threatened to end their drought last season.

They were only a point adrift of Juventus when the league was suspended due to the coronavirus pandemic in March last year.

But when the 2019-20 campaign resumed, Lazio stumbled and eventually finished third – four points behind Juve as the Turin powerhouse claimed a ninth consecutive Serie A crown.

"Everyone stopped playing, not only Lazio. The thing is, when you play and you don't need to win the Scudetto, you play with no pressure," the 47-year-old Vieri explained.

"When they say to you, there's 8-10 games to go and we have to win all eight, and tomorrow we have to win, it changes. You stop sleeping. You're nervous because you have to win.

"One thing is winning the game and no one says anything – you're second or third but no one expects you to win. But when they say there's five games to go and you have to win all five, that changes everything.

"When they started again after COVID-19, they had to win the last six or seven games and didn't do that. Juventus are used to the pressure. That's how it is."

Roses are red, violets are blue, have we got the perfect Valentine's Day content for you!

Questionable rhymes aside (okay, very questionable), love is in the air as long-standing couples and newly formed relationships celebrate the day of romance on Sunday.

The world of football is certainly no stranger to the language of love, so before you crack open a bottle of red and exchange cheap knock-off gifts with your significant other why not get some inspiration for love with our Valentine's Day facts with some help from Cupid!

(Well not Cupid, Opta – but the team at Opta are full of love!)

MATT LE KISS-IER LOVES TO SCORE ON VALENTINE'S DAY

Valentine's Day is of course a day for love (and overpaying for those last-minute flowers and cards you forgot to buy…).

Two players have been particularly good at spreading the joy on February 14th with Southampton legend Matt Le Tissier and ex-Liverpool striker Michael Owen each scoring three times in the Premier League on this date – the most of all players.

Here's something even more interesting about that stat, though – each man's tally is a result of scoring a Valentine's Day hat-trick.

Le Tissier registered three against the Reds back in 1994, while Owen took home the match ball with a treble versus Sheffield Wednesday four years later.

Owen's three goals are part of 12 Liverpool have tallied on the day of love – comfortably the most by a team. Arsenal follow on seven, with Aston Villa and Southampton on four.

A ROSE FOR THE LADY?

Flowers are synonymous with Valentine's Day but none more so than the rose.

Two players named Rose have plied their trade in the Premier League – Danny (194 appearances) and Matthew (five appearances). The former, of course, is an England international who with his marauding runs from full-back has often been a, ahem, thorn in the side of opponents…

There are other love-themed names to have featured in the top flight. Valentino Lazaro played 13 times in the Premier League for Newcastle United on loan last term, while Valentin Roberge made 10 appearances for north east rivals Sunderland.

The Black Cats also had Donald Love on their books, the defender having previously represented Manchester United once in the top flight.

FOXES RACK UP THE CARDS

Whether from a partner or a secret admirer, it's always nice to receive a card or two on Valentine's Day.

Unless of course you're playing in the Premier League, in which case you want to see the referee keep their cards in their pockets.

In this regard, Leicester City have not been overly successful – the seven yellow cards representing the most received by a team on Valentine's Day. Arsenal follow closely behind with six, with Manchester City on four.

The Foxes also fare badly when it comes to red cards, having picked up two on February 14th – Danny Simpson and Hamza Choudhury account for those dismissals. The only other player to have been sent off on Valentine's Day is Everton hero Duncan Ferguson ... no, we weren't shocked either.

THE BEST BROMANCES

It goes without saying that we don't need to confine our love sharing to one manufactured day of the year…

No, we should be spreading the joy in our hearts all year round and these strike partnerships certainly succeed in that category.

Going back to the start of the 2015-16 season, no two players have combined for more goals than Spurs duo Harry Kane and Son Heung-min (33).

In fact, Kane features three times in the top-five – also ranking third with Christian Eriksen (19), and sharing 18 with Dele Alli.

Manchester City pairing Sergio Aguero and Kevin De Bruyne are second with 20, while Jamie Vardy and Riyad Mahrez (18), who fired Leicester to shock title glory in 2015-16, also feature.

Dominic Thiem's bid to reach back-to-back Australian Open finals was dashed by Grigor Dimitrov as the US Open champion surprisingly crashed out in the round of 16.

Thiem lost a thrilling final to Novak Djokovic in last year's Melbourne Park decider before breaking through for his maiden grand slam title at Flushing Meadows later in 2020.

But Thiem failed to secure another second-week berth in Melbourne, where the third seed was stunned 6-4 6-4 6-0 by former world number three Dimitrov on Sunday.

Thiem was aiming to reach the Australian Open quarter-finals for the second time and become the second Austrian man to feature in the quarters in Melbourne on multiple occasions after Thomas Muster (1989, 1994 and 1997).

The 27-year-old Thiem was also bidding to reach his ninth slam quarter-final and equal Muster's record for most major last-eight appearances by any Austrian – male or female.

However, Thiem – who rallied from two-sets-to-love down to top Nick Kyrgios in the previous round – was no match for Dimitrov behind closed doors on Rod Laver Arena amid a coronavirus lockdown in Victoria.

Both players hit 25 winners, but Dimitrov only tallied 18 unforced errors to Thiem's 41 following just over two hours on court.

Dimitrov progressed to his fourth Australian Open quarter-final, extending his record for most last-eight appearances at Melbourne Park by a Bulgarian player – man or woman.

An Australian Open semi-finalist in 2017, Dimitrov will now contest his sixth grand slam quarter-final – the 29-year-old is third for most quarter-final appearances by a Bulgarian player, behind Manuela Maleeva (nine) and Katerina Maleeva (seven).

Wayne Pivac urged Wales not to get carried away with making it two wins from two in this year's Six Nations by beating Scotland 25-24 at Murrayfield on Saturday.

Darcy Graham and Stuart Hogg put Scotland 14 points ahead in the first half, only for Louis Rees-Zammit to reduce the deficit before half-time.

Liam Williams and Wyn Jones touched down either side of a red card for Zander Fagerson to put Wales in front for the first time, before Hogg went over again for the depleted hosts.

However, Rees-Zammit scored a brilliant solo try to seal a bonus-point victory, which followed a win over 14-man Ireland on the opening weekend of the tournament.

Prior to this year's Six Nations, Wales had won just three of Pivac's first 10 Tests at the helm and he urged them to remain grounded despite the upturn in results.

"From 17-3 down against a side full a confidence, it was very, very pleasing," said Pivac.

"There were some big moments from both sides so we are just happy to come away with a win.

"We are improving each week in certain areas of the game and we showed a lot of character today.

"The squad has changed a lot since autumn, and it's tournament rugby now, a couple months is a long time to reflect.

"We cannot get carried away with this, though, and we need to build on it."

Having also set up Williams' try, Rees-Zammit has been directly involved in six tries in just five starts for Wales (four scored, two assisted).

Pivac said of the Gloucester wing: "Louis Rees-Zammit is doing some very good things with the ball. He's got things to work on, he dropped a high ball earlier and he wasn't the complete package, but he has scored some really well-worked tries."

Hogg took his Test try tally to 22, with Ian Smith and Tony Stanger (both 24) the only players to have registered more for Scotland.

He was frustrated Gregor Townsend's men let the game slip through their fingers a week after a famous victory over reigning champions England at Twickenham.

"We're bitterly disappointed. For large parts of that game we were very much in control of it. We looked the dominant side, especially in the first half, and we started to be ill-disciplined," he told the BBC.

"For us, giving away a couple of penalties is fine, four on the bounce is unacceptable. We've gone from one end of the field to the other conceding seven points within a couple of minutes and that's international rugby. You can't let a team like Wales get easy, cheap field positions because they are going to punish you.

"I think, for us, it's a vital lesson to stay disciplined throughout. It hurts right now, and rightly so."

Lionel Messi equalled Barcelona's all-time LaLiga appearances record set by Xavi by starting Saturday's clash with Deportivo Alaves.

It was thought Ronald Koeman might opt to leave Messi out given the importance of Tuesday's Champions League round-of-16 first-leg game against Paris Saint-Germain.

However, given the depleted nature of the Barca squad at the moment, Koeman made the decision to include his captain from the start.

It was Messi's 505th LaLiga appearance for Barca, tying the haul managed by club great Xavi, and the Argentinian could surpass his former team-mate next week at home to Cadiz.

Lorenzo Insigne scored his 100th goal for Napoli to earn his side a 1-0 win over Juventus in Saturday's Serie A clash, easing some of the growing pressure on boss Gennaro Gattuso.

Juve had won their last three top-flight games by the same 2-0 scoreline but their title prospects took another dent with defeat to a spirited Napoli side at Estadio Diego Armando Maradona.

Giorgio Chiellini marked his landmark 400th Serie A appearance by giving away a penalty that was put away by Insigne for what proved to be the only goal of the contest.

Cristiano Ronaldo and Alvaro Morata went close to equalising but the visitors, who beat Napoli 2-0 in last month's Supercoppa Italiana, could not find a way through.

Napoli were already without a number of key men and lost first-choice goalkeeper David Ospina to injury in the warm-up, meaning a late call-up to the side for Alex Meret.

The hosts were fortunate to see Federico Bernardeschi balloon a promising chance into the stands but they took the lead 31 minutes in through Insigne's powerful penalty.

Chiellini jumped with his arm and caught Amir Rrahmani in the face, which VAR adjudged was worthy of a spot-kick, and Insigne did not waste the chance to bring up his century.

Juve, who had not conceded in their previous three Serie A games, should have been level early in the second half but Ronaldo fired straight at Meret from close range.

Meret was also equal to Federico Chiesa's drive and Morata had a goal ruled out following another Chiellini foul on Rrahmani in the build-up as Juve continued to press.

A final chance fell Morata's way late on but he could not get the better of inspired Napoli keeper Meret, who produced a fine save with his legs to help his side to a huge win.
