Alexander Zverev is targeting an elusive grand slam title after the Olympic Games gold medallist capped a fine year with ATP Finals glory.

Zverev outmatched defending champion and second seed Daniil Medvedev 6-4 6-4 to claim his second ATP Finals crown in Turin on Sunday.

Champion at the Tokyo Games, Zverev became the first player to beat the world number one and two in the semis and final since Andre Agassi in 1990, having upstaged Novak Djokovic in the final four.

After celebrating his 59 tour-level victories – the best on tour – Zverev turned his attention to grand slams.

Despite his success at the Olympics and Masters 1000 level, Zverev is yet to break through at slams having lost last year's US Open final, while reaching three semi-finals previously.

Asked if he was closer than ever to winning a slam, Zverev replied: "I think so, yeah. I mean, why not, right?

"I've kind of succeeded at every single level. There's one thing missing. I hope I can do that next year."

Zverev, who claimed a tour-leading sixth title this season, added: "They [things] couldn't be much better, to be honest.

"I'm obviously happy with how the season went, I'm happy with the finish of the season because obviously it was a great year.

"To capture the title here has been incredible."

US Open winner Medvedev also backed Zverev to conquer a grand slam tournament, saying: "Sascha is a great player who is capable of beating anybody, so he definitely can win a Grand Slam, because It’s just obvious.

"But he's not the only one and that's where it gets tough. He was in the semi-finals of the US Open and lost in five sets [to Djokovic]. Who knows maybe if he was in the final he might have beaten me.

"It's just a matter of every tournament is a different scenario and surface, you have to win seven matches to be a grand slam champion. Is he capable? Yes. Is he going to do it? We never know."

The Los Angeles Lakers overturned a 17-point deficit and a chaotic third-quarter brawl which led to LeBron James' ejection to trump the lowly Detroit Pistons 121-116.

James was ejected after an elbow to the eye of Pistons center Isaiah Jackson, who reacted angrily, leading to a wild melee in Detroit on Sunday.

Jackson repeatedly charged at James and had to be restrained by team-mates and coaches. Both players were ejected, with the latter's elbow deemed a flagrant 2 foul.

The Lakers were trailing by 12 points at the time of the incident early in the third quarter, before Russell Westbrook and Anthony Davis led a rally on the road.

Westbrook (26 points, 10 assists and nine rebounds) had 15 points, six assists and five rebounds in a final period dominated by the visiting Lakers 37-17.

Davis had 30 points, 10 rebounds, six assists, five blocks and four steals – the star becoming the first Laker with a 30/10/5/3/5 game since Hall of Famer Shaquille O'Neal in 2001.

James, in his second game back after an abdominal injury laid him off for two and a half weeks, played 21 minutes for 10 points and five assists before his ejection as the Lakers improved to 9-0 for the season.

Number one draft pick Cade Cunningham registered his first career triple-double for the Pistons with 13 points, 12 rebounds and 10 assists.

Suns maintain hot streak

The Phoenix Suns recorded their 12th straight win as Cam Johnson had a career-high and game-high 22 points off the bench, including four triples in a 126-97 rout of the Denver Nuggets, who were without MVP Nikola Jokic (shoulder) for the second successive game. Chris Paul (nine points and 10 assists) has had 47 games with 10-plus assists and 0 turnovers since entering the league in 2006. He has the most such games since 1985.

Paul George hauled the Los Angeles Clippers past the Luka Doncic-less Dallas Mavericks 97-91 with 29 points and six assists. The Mavs were still without Luka Doncic (knee/ankle).

DeMar DeRozan scored 31 points in the Chicago Bulls' 109-103 victory over the New York Knicks. Julius Randle posted 34 points for the beaten Knicks, who led entering the final quarter.

Mild Curry returns

Stephen Curry returned from a minor hip issue but was well down on his usual output with only 12 points, making two of 10 field-goal attempts and one of six beyond the arc in the Golden State Warriors' 119-104 triumph over the Toronto Raptors.

Anthony Davis defended Los Angeles Lakers team-mate LeBron James after his ejection in the wild win over the Detroit Pistons, insisting the NBA superstar is not a "dirty dog".

James was ejected for an elbow to Pistons center Isaiah Stewart's eye, which was deemed a flagrant 2 foul, with the incident setting off a wild brawl in the Lakers' rallying 121-116 victory.

Stewart, who was also tossed from the game, was left bloodied from his right eye and incensed, repeatedly attempting to charge at James, having to be restrained and escorted off the court by coaches and team-mates amid chaotic scenes.

James and Stewart had jostled for position for a rebound from Jerami Grant's free throw early in the third quarter, when the four-time MVP's left elbow struck the Pistons big man's eye.

"Everyone in the league knows LeBron's not a dirty dog," said Davis, led the Lakers' comeback with 30 points, 10 rebounds, six assists, five blocks and four steals. "As soon as he did it, he looked back at him and said 'my bad, I ain't try to do it'.

"I don't know what [Stewart] was trying to do. I know nobody on our team, one through to 15, was having it. We wanted to protect our brother.

"I've never in 10 years seen a player try to do that... It was uncalled for. You got a cut above your eye, accidental, it wasn't on purpose.

"We weren't going to allow him to keep charging our brother like that. I don’t know what he was trying to do. We just wanted to get the win for him."

The Lakers were trailing by 12 points at the time of the incident but went on to win behind Davis' big performance on the road.

Davis became the first Laker with a 30/10/5/3/5 game since Hall of Famer Shaquille O'Neal in 2001.

Russell Westbrook (26 points, 10 assists and nine rebounds) was important down the stretch too, with 15 points, five rebounds and six assists in the fourth quarter alone, as the Lakers dominated with a 37-17 final quarter.

Amid the chaos of the brawl, Westbrook received a technical foul which left him dumb-founded post-game, stating he was an easy target for the referees.

"I didn't know I had a tech… woah, that's interesting," Westbrook told reporters. "For being Russell, I guess? I don’t know why but whatever.

"They had to put it on somebody. I'm an easy person to put s*** on. Why not me?"

Lakers head coach Frank Vogel hailed his side's response to the incident, reeling in the Pistons' game-high 17-point lead to claim a win that helped the championship-chasing franchise improve to 9-9 for the season.

"To me, it's one of those things that can change the momentum of your season," Vogel said. "To see guys rally around a team-mate that just got ejected like that in a strange circumstance.

"We played with incredible guts, started the fourth quarter down by 15. That's the determination that this team is going to need. That's how hard we've got to play to get Ws. "That's a heck of a win for us."

Ajax head coach Erik ten Hag is focused on winning titles with the Eredivisie, insisting he has "heard nothing" about the Manchester United job.

Ten Hag has emerged as one of the leading contenders to fill the United vacancy after manager Ole Gunnar Solskjaer was sacked on Sunday following Saturday's humiliating 4-1 Premier League rout at Watford.

Ajax's Ten Hag has impressed in his time in Amsterdam, where he has delivered two Eredivisie titles and embarked on a memorable run to the 2018-19 Champions League semi-finals.

Ten Hag's side have been the entertainers of Europe this term, dazzling their way into the Champions League round of 16, while topping the Eredivisie ahead of rivals PSV on goal difference.

The 51-year-old Dutchman was asked about United's reported interest after Sunday's 5-0 demolition of RKC Waalwijk.

"I am focused on my team, we have a brilliant squad and we want to achieve a lot," Ten Hag told ESPN.

"We have a brilliant squad, we want to fight for titles. My focus is on Ajax, the rest only distracts.

"I expect from my players that they are focused on Ajax, so I have to give the right example for that too.

"You keep asking me [about my position as Ajax manager], yes it is a weird question. I heard nothing about [United's interest], so I can't think about it."

Ajax have scored 42 goals in 13 rounds this season, conceding just twice.

Ten Hag's Ajax have kept 20 clean sheets in the league in 2021, their most in a calendar year since 1997 (21).

Ajax have been led by Sebastien Haller, who has scored 17 goals in 18 appearances across all competitions.

Haller has scored the opening goal in the Eredivisie nine times in 2021 – the most for a player in a calendar year since Graziano Pelle in 2013.

Felix Afena-Gyan thanked Jose Mourinho after the teenage sensation opened his Roma account with a stunning brace off the bench to sink Genoa 2-0 in Serie A on Sunday.

Afena-Gyan enjoyed a fairytale outing, the 18-year-old substitute scoring twice to ruin Andrey Shevchenko's debut as Genoa head coach.

With the score deadlocked at 0-0, Afena-Gyan was introduced by Mourinho in the 75th minute and turned the match on its head, breaking the deadlock seven minutes later.

After sprinting to celebrate with Mourinho, the Ghanaian forward then sealed the victory with a sublime strike in the fourth minute of stoppage time at Stadio Luigi Ferraris.

"I thank God for this opportunity he gave me, the team, the coach, the fans, players for their amazing support," Afena-Gyan told DAZN.

"I also want to say thank you Mom, she is in Ghana, I love you."

It was a memorable night for Afena-Gyan, who became the first player born after January 2003 to score at least one goal in Serie A.

Afena-Gyan ticked off a number of feats – the youngest player to score more than one goal in a match in this season's top-five European League (18 years, 10 months and two days), youngest foreign player in Serie A's three-point era (since 1994-95) to score for Roma, youngest foreign player to net more than once for the Giallorossi in Serie A since 1994-95, while he is the first Ghanian to score for the capital club.

Afena-Gyan added: "Mourinho is a great person, a great manager and a great coach. He gives you the motivation to learn every day. I am very happy he is here.

"Tonight is a dream come true. It was my first goal, I was hoping for a very long time. I want to continue my performance, prove myself and do more in future."

Afena-Gyan was making only his third appearance for Roma, having been introduced to the senior side by veteran boss Mourinho in Rome.

"I had promised to buy Felix the boots he really likes, which are really expensive, they cost €800, so he ran over and told me not to forget! Tomorrow morning, the first thing I do is buy him the boots," Mourinho told DAZN.

"I am sorry for Mister [Daniele] De Rossi and the Primavera squad, but Felix will stay with us. The Primavera work close to us, so Felix and another four or five players have come across to the senior squad.

"What impressed me the most was his cool head in front of goal. If he is not in terms of technique fantastic, he does have a strong mentality.

"You get these kids now who think they know everything, but he is humble and you can sense he just absorbs all this information from everyone around him. That's fantastic."

The Sacramento Kings fired head coach Luke Walton amid their struggles this season, the NBA franchise announced on Sunday.

Sacramento lost patience with former Los Angeles Lakers coach Walton after losing seven of eight games to drop to 6-11 in 2021-22.

The Kings – who are 12th in the Western Conference and have not reached the playoffs since 2005-06 – promoted associated head coach Alvin Gentry to take over on an interim basis.

"After a thorough evaluation of the season thus far, I decided to make a change to the head coach position," said Kings general manager Monte McNair.

"I want to thank Luke for his efforts and contributions to our team."

Walton – an NBA champion as a player with the Lakers – had a 68-93 record as Kings coach following his arrival in 2019.

The Kings have had 10 coaches since last featuring in the postseason, with Gentry set to be the 11th since Rick Adelman guided the franchise to a 34-35 finish in 2006 and a first-round berth.

Lyon's Ligue 1 home match against Marseille was abandoned after Dimitri Payet was hit by a bottle hurled by a spectator, heaping fresh embarrassment on the French game.

Former West Ham playmaker Payet was preparing to take a corner amid a hostile atmosphere when he was struck on the side of the head by a plastic bottle full of liquid.

He immediately went to ground and needed treatment, prompting referee Ruddy Buquet to take the players off the pitch. Payet left the field with an ice pack pressed to the side of his head.

Lyon president Jean-Michel Aulas later said a spectator had been arrested in connection with the bottle throwing, and offered an apology to Payet.

The Ligue de Football Professionnel (LFP) said its disciplinary chiefs would meet on Monday, describing the rash of violent incidents in Ligue 1 as acts that are "destroying the image of the championship in France and internationally".

Lyon could face a points deduction over the incident, with Nice having been docked two points, one of which was suspended, after crowd trouble at their game against Marseille earlier this season.

The LFP said it "strongly condemns the violent aggression" that Payet suffered. "Dimitri Payet was also the target of discriminatory insults," the LFP said.

It added a firm warning that fan misconduct will lead to sanctions, stating: "Despite the firmness of the decisions of the disciplinary commission of the LFP since the start of the season [withdrawal of points, closed-door match, closure of the stand] and the work carried out with the government authorities to more effectively punish violent individuals in the stadiums, these new serious incidents are a reminder that the safety of the matches is the responsibility of the home club and the local authorities, who are ultimately responsible for resuming or definitively stopping the match."

There was a bizarre sideshow to the serious business of the assault on Payet, as the LFP and local authorities took contrasting views on what happened after the players were hauled off the pitch.

The LFP claimed a decision had been taken by the local Rhone prefecture to resume the game, but those officials hit out at the league authorities and said they had made no such declaration, stressing that Buquet decided it should start again before changing his mind.

Fans stayed inside the Groupama Stadium long after the incident occurred, in the hope of a resumption that never came, even though at one point it looked like doing so when the players returned to the pitch to warm up. 

The Rhone local government officials said in a statement on Twitter that a "crisis meeting" had taken place, attended by their representatives and others, including match officials and presidents of both clubs, at which referee Buquet decided the match should resume.

The Rhone officials issued a subsequent statement taking issue with the LFP take, describing it as "FALSE", adding: "The referee then invites the authorities and club presidents to his dressing room to say that he has changed his mind and that he is stopping the match."

There have been a number of major crowd trouble incidents in French football this season, starting from the opening weekend when Marseille midfielder Valentin Rongier was hit by a bottle while celebrating a goal that Payet scored against Montpellier.

Marseille and Payet were on the receiving end later in August after Nice fans hurled bottles onto the pitch. Payet was struck and hurled the bottle back into the stand, sparking a pitch invasion by Nice ultras. That match was abandoned and replayed behind closed doors at Troyes' neutral ground in October, with Nice served with their points penalty.

Saint-Etienne and Angers were delayed by an hour in starting their October 22 game after angry fans hurled flares onto the pitch and demanded Claude Puel quit as Saint-Etienne boss. There was also trouble at Saint-Etienne's game against Lyon, while the clash between Lens and Lille in September was held up after rival fans clashed at half-time.

Carlo Ancelotti hailed his Real Madrid midfield as the best in the world after Toni Kroos, Luka Modric and Casemiro turned on the style in a 4-1 win at Granada.

Kroos grabbed his first two assists of an injury-blighted season, while Modric and Casemiro laid on a goal apiece in an impressive rout on Sunday, as Madrid beat Granada for a 13th successive time in LaLiga.

The last time Granada scored a home win over Madrid was in February 2013, when they won 1-0 thanks to a Cristiano Ronaldo own goal, his only such blunder in 292 appearances in the Spanish top flight.

There was no danger of a repeat as Madrid grabbed this game by the scruff of the neck and were 3-1 up and chasing more goals by the time their hosts had Monchu sent off for a wild challenge on Vinicius Junior.

Marco Asensio, Nacho, Vinicius and Ferland Mendy got the goals, but Madrid's midfield three were outstanding, as Ancelotti admiringly acknowledged after the game.

With Real Sociedad only able to draw against Valencia in the evening game, it meant Madrid finished the weekend on top of the table by one point.

"What can you say," Madrid head coach Ancelotti told reporters. "They're playing at a very high level and are still the best midfielders in the world for me. They're doing things that I don't even ask from them, they do it naturally, and it's a big advantage for this club.

"They are the past, present and the future. If we're talking about the near future, absolutely. If we're looking in 10 years' time, then perhaps not. But we're in good shape for the future because [Eduardo] Camavinga, [Federico] Valverde and [Antonio] Blanco are ready too.

"They're used to playing together and they have qualities which are hard to explain. The way they switch positions during the game, sometimes Modric drops deep to play through the press and sometimes it's Kroos, Casemiro moves forward."

Kroos created a game-high four chances and finished the game with a passing accuracy of 97.4 per cent.

Madrid could have had more goals, but Granada goalkeeper Luis Maximiano made five saves. It was the fourth time this season the young Portuguese has made five saves or more in a LaLiga game, and only Espanyol's Diego Lopez has done so on more occasions (seven).

Ancelotti included Nacho at centre-back out of a wish to give Eder Militao a rest. He substituted the lively Vinicius late on, too, but stressed that was not due to injury but out of a wish to protect the young Brazilian.

"I took Vini Jr [off] to avoid any issues," Ancelotti said, quoted on Madrid's website. "The game was heating up, for us and for Granada I thought it was best to take him off."

Napoli star Victor Osimhen will undergo surgery after suffering multiple facial fractures during the 3-2 Serie A defeat to Inter.

Osimhen was hurt in a clash of heads with Inter defender Milan Skriniar as the Nerazzurri ended leaders Napoli's unbeaten start to the season on Sunday.

He was substituted in the 55th minute and taken for tests, which the club later confirmed had revealed "multiple displaced fractures of the left orbit and cheekbone".

"The player will undergo surgery in the next few days and will remain under observation at Niguarda Hospital in Milan tonight [Sunday]," Napoli said.

Osimhen is Napoli's leading goalscorer in 2021-22, with five in Serie A and four in the Europa League.

The Nigeria international scored seven times in September alone, a tally matched only by Real Madrid striker Karim Benzema across Europe's top-five leagues.

Only Borussia Dortmund's Erling Haaland was younger than Osimhen, who turns 23 next month, among players in those top-five leagues to score 10 or more goals in both 2019-20 and 2020-21.

Simone Inzaghi urged Inter to build on their strong performance against Napoli after ending the Serie A leaders' unbeaten start to the campaign.

Piotr Zielinski netted Napoli's first away goal in four league games against the Nerazzurri to open the scoring with their first strike at San Siro since April 2017.

However, Hakan Calhanoglu equalised from the spot before teeing up Ivan Perisic's header to put Inter 2-1 up at half-time, the Turkey international recording at least a goal and an assist in a Serie A match for the 10th time since his debut in 2017-18.

Lautaro Martinez seemed to have put the game out of Napoli's reach, though substitute Dries Mertens' pulled one back to overtake Antonio Vojak as the club's leading scorer in the Italian top flight with his 103rd goal.

The defending champions managed to hang on to end Napoli's 21-game unbeaten league run, taking them within four points of the top two, and Inzaghi wants more from his side ahead of a crucial Champions League clash with Shakhtar Donetsk on Wednesday.

"It was a key game for the season, although the most important one will be in three days' time," Inzaghi told DAZN.

"We beat a very strong Napoli side and we did it deservedly too. It's always going to be a struggle against Napoli, especially as they have on average the highest possession statistics in Serie A this season with 60 per cent.

"We must continue like this. We've got to focus on the Champions League next because it's been too many years that Inter haven't got past the group phase and we have a big opportunity to achieve it.

"Wednesday we have a great chance, we have some injuries but it's a moment like this for everyone. We have to move forward match after match. We have left some points because the Champions League is very important for us."

Inter had Samir Handanovic to thank for the three points after his stoppage-time save against Mario Rui in which he tipped onto the crossbar from the left-back's header at the back post.

Mertens then blasted over during a chaotic eight minutes of additional time and Inzaghi admitted he was concerned in the closing stages while explaining why Calhanoglu got to take the first-half penalty.

"We had been a whisker away from winning several of the other head-to-head clashes, so a little fear was inevitable towards the end during eight minutes of stoppages," he added.

"We had tests in training, Perisic, Calhanoglu and Lautaro took three penalties each and scored all three, so I said just decide between yourselves! Hakan is in great shape at the moment and I wouldn't have taken him off if he wasn't on a yellow card today."

Dimitri Payet was hit by a bottle thrown from the crowd early in Lyon's home game with Marseille, causing Sunday's big Ligue 1 clash to be suspended.

Former West Ham playmaker Payet was preparing to take a corner amid a hostile atmosphere when he was struck on the side of the head by a bottle full of liquid.

He immediately went to ground and needed treatment, prompting referee Ruddy Buquet to take the players off the pitch.

Payet left the pitch with an ice pack pressed to the side of his head.

There have been a number of major crowd trouble incidents in French football this season, starting from the opening weekend when Marseille midfielder Valentin Rongier was hit by a bottle while celebrating a goal that Payet scored against Montpellier.

Marseille and Payet were on the receiving end later in August after Nice fans hurled bottles onto the pitch. Payet was struck and hurled the bottle back into the stand, sparking a pitch invasion by Nice ultras. That match was abandoned and replayed behind closed doors at Troyes' neutral ground in October.

It remained to be seen whether Sunday night's game would continue, with the players still off the pitch more than half an hour after Payet was hit.
