Serena Williams played down her prospects of winning a record-equalling 24th grand slam title at the French Open, insisting the standard on the WTA Tour is now so high that every match is a battle.

The three-time champion at Roland Garros made it through to the last 16 thanks to a 6-4 6-4 win over Danielle Collins.

However, the American - who has been stuck one slam behind Margaret Court's career tally ever since winning the 2017 Australian Open - had to work hard on Friday, including battling back from 4-1 down in the second set as she reeled off five games in a row to move on.

Williams is the only top-10 player left in her half of the draw following Aryna Sabalenka's exit earlier in the day, yet knows there is a long way to go in her quest to reign once more in the Paris.

"There's still a lot of matches, a lot of great players, as we can see," Williams told the media.

"There's so much depth in this game now, it doesn't matter if you're playing in the first round or not, you really have to fight for every match and nothing comes easy."

After struggling for form coming into the tournament, Williams feels tough contests like the one she had against Collins can only be beneficial.

"Today in particular, this whole week thus far, I just needed a win," the seventh seed said. "I needed to win tough matches. I needed to win sets. I needed to win being down.

"I needed to find me, know who I am. Nobody else is Serena out here. It's me. It's pretty cool."

Elena Rybakina – an impressive 6-1 6-4 winner against Elena Vesnina in little over an hour - is the next hurdle for Williams to clear.

SABALENKA SUNK, AZARENKA EASES THROUGH

With Ashleigh Barty forced to retire through injury and Naomi Osaka withdrawing from the event due to mental health concerns, Sabalenka was the highest seed left – well, she was until coming up against Anastasia Pavlyuchenkova.

Sabalenka rallied after losing the first set to draw level but then fell apart in the decider, serving four double faults and producing 17 unforced errors.

Pavlyuchenkova capitalised to complete a 6-4 2-6 6-0 triumph that avenges a loss to her opponent at the semi-final stage in Madrid during this year's clay-court swing.

Next up for the 31st seed will be Victoria Azarenka, the former world number one who eased past Madison Keys 6-2 6-2.

"I felt I played very disciplined today. I played smart. I tried to be aggressive," Azarenka said after winning in 70 minutes.

"My opponent, Madison, she really likes to dictate the points, so I tried to take that away from her, really step in, and make a lot of different balls so I’m pretty proud I was able to sustain my level."

MIXED FORTUNES FOR ROMANIAN DUO

Sorana Cirstea explained how a change in approach has helped her roll back the years after overcoming Daria Kasatkina in straight sets.

The Romanian's solitary quarter-final appearance at a slam came in the French capital 12 years ago but she has been in excellent form on clay this year, including claiming a title in Istanbul and a final appearance in Strasbourg.

"I'm taking it day by day, like I'm not going too far ahead with my mind," Cirstea told the media. "I'm actually enjoying all this process. Definitely I'm enjoying [it] much more than I did 12 years ago, and I think this comes with maturity."

While Cirstea has not made it this far in a grand slam for a long while, next opponent Tamara Zidansek is into the last 16 at a major for the first time.

Despite losing the first set in a hurry against Katerina Siniakova, the Slovenian rallied impressively to seal a 0-6 7-6 (7-5) 6-2 victory and continue an impressive run that was started by an upset over Bianca Andreescu.

Paula Badosa also needed three sets to overcome Romania's Ana Bogdan, including saving a match point, and extend her winning streak to eight matches as she came out on top 2-6 7-6 (7-4) 6-4. Indeed, for the season she now boasts a 16-2 record on clay.

Spain and Portugal drew 0-0 at the Wanda Metropolitano on Friday in an engaging warm-up friendly ahead of Euro 2020.

The previous two champions of Europe could not be separated in Madrid as Alvaro Morata and Diogo Jota missed the pick of the chances.

Luis Enrique and Fernando Santos named strong starting line-ups for an energetic first half, with Manchester City's Aymeric Laporte winning his first cap at the heart of the Spanish defence.

Laporte was a little fortunate not to be punished with 21 minutes left as Cristiano Ronaldo got free in the box before heading wide from one of the quieter second half's few good openings.

After a slick start in possession, Spain looked to have conceded from Portugal's first attack, but Jose Fonte's powerful header was disallowed for a push.

Ferran Torres missed Spain's first clear-cut chance, nodding wide at the far post after Morata crossed expertly from the left.

Ronaldo and Renato Sanches combined well to trigger a counter-attack, and the Portugal captain was almost presented with a chance when Spain goalkeeper Unai Simon's attempted clearance cannoned off the Juventus star.

Morata threatened twice just after the restart, denied by Simon and then by a Fonte block, with his follow-up effort bobbling wide, before Pablo Sarabia steered a good chance over the bar.

Portugal then should have taken the lead on the hour mark, Jota's header from six yards out deflected over after Ronaldo clipped a cross to the left-hand post.

Ronaldo then glanced wide from Bruno Fernandes' wicked delivery, Laporte given a let-off after allowing the forward a free header in the box.

Koke almost forced the winner in the closing minutes, his free-kick from the left of the box parried away by Rui Patricio before it could creep into the bottom-right corner. Morata should have won the contest in injury time, but could only rattle the crossbar after being gifted a free run at goal.

What does it mean? Euros heavyweights in need of sharpening before finals

Each of these sides have reason to be pleased with their performance on Friday, although a few more training sessions for the forwards would not go amiss.

There were just three efforts on target in the contest and two of those came in the dying minutes through Koke's free-kick, which was glanced on by Torres, and a last-gasp header from Danilo Pereira that Simon saved comfortably. 

Busquets doing the old guard proud

Sergio Busquets is one of the few surviving bastions of Spain's 2008-2012 dominance of the international stage, keeping his place in the squad despite not always looking his sharpest for Barcelona in 2020-21.

He managed 63 commanding minutes here at the heart of midfield, winning back possession 12 times and making 34 passes in the Portugal half – each game-high totals during his time on the pitch.

Few home comforts for Joao Felix

Atletico Madrid's Joao Felix gave the home fans few reasons to worry in his 45-minute outing.

Ill-suited to Portugal's early counter-attacking play, he completed only six passes before being withdrawn at the break for debutant Pote.

What's next?

Each side has one more warm-up game before their Euros campaigns start. Spain face Lithuania in Leganes on Tuesday, while Portugal host Israel in Lisbon on Wednesday.

The Singapore Grand Prix is cancelled and "several options" for alternative races are being considered, Formula One organisers have confirmed.

The race at the Marina Bay Street Circuit was originally scheduled for October 1-3 this year.

However, the event has been called off amid concerns from authorities that Singapore's strict coronavirus control measures would not be compatible with thousands entering the country for the weekend.

A statement from F1 on Friday said: "Formula One and race organisers have confirmed that this year's Singapore Grand Prix will not take place, with organisers citing ongoing safety and logistic concerns brought about by the Covid-19 pandemic.

"As previously stated, Formula One say they will continue to work with all promoters during this fluid time and have several options for additional races."

Colin Syn, deputy chairman of the race, was quoted by the BBC as saying that cancelling the Singapore event for the second year running was "an incredibly difficult decision" but necessary due to "the prevailing restrictions for live events in Singapore".

The city state has tough measures in place to limit travel from abroad, while a robust test-and-trace system has helped to keep COVID-19 cases to just over 62,000.

According to reports, Turkey is being considered as an alternative venue. Istanbul Park was due to be used as a substitute for the Canadian Grand Prix but was cancelled after a rise in coronavirus cases.

A revival of the postponed Chinese Grand Prix and a possible second race in Austin, Texas have also been mooted.

Serena Williams produced an emphatic fightback in the second set to eliminate Danielle Collins 6-4 6-4 and secure a spot in the last 16 of the French Open.

While the first set provided few difficulties for the 23-time grand slam winner, she found herself trailing 4-1 in the second as Collins threatened to force a decider.

But Williams channelled her frustrations impressively, and far better than her opponent, with the 39-year-old setting up a fourth-round clash with Elena Rybakina.

Williams might have had an early advantage as some brutal returns gave her three break points in just the second game of the match, but Collins came back to hold.

The first break eventually came in the seventh game of the contest, Williams squeezing a shot over after a drop shot, then guiding a return to the back of the court with Collins in no position to respond.

Although a second break in the first set eluded Williams, she sealed the set on her serve soon after.

The second set saw Collins' serve broken in the first game, but her response was emphatic, producing back-to-back breaks of her own.

That had Collins in control of the set at 3-1 up, with Williams' frustration evident at the end of almost every point and not helped by her five double faults, one of which gifted away a second break.

Williams began to use that anger for good as she played even more aggressively.

Initially Collins rode the punches well, playing Williams impressively as she forced the seventh seed out wide and then read her cross-court return to seal the fifth game to love and a 4-1 lead.

But Collins quickly fell apart, Williams winning five games on the trot as she came back from a precarious position to seal her progression, showing commendable mental fortitude along the way.

DATA SLAM: GO BIG OR GO HOME

It is fair to say Williams' serving was a little wild at times – she was looking to be aggressive to put Collins on the back foot as early as possible. However, it left her with as many double faults as aces, five apiece. Nevertheless, the three-time French Open champion got the job done, with a huge serve ultimately sealing the victory.

WINNERS/UNFORCED ERRORS

Williams – 22/20

Collins – 18/21

ACES/DOUBLE FAULTS

Williams – 5/5

Collins – 1/3

BREAK POINTS WON

Williams – 4/8

No play was possible on day three of the first Test between England and New Zealand at a soggy Lord's.

England had been due to resume on 111-2 in their first innings after bowling out the Black Caps for 378, only for persistent rainfall throughout Friday to make sure the players never made it out onto the field.

Saturday's action will be extended to try to make up some of the time lost with 98 overs now scheduled – weather permitting, of course.

Opener Rory Burns and captain Joe Root are the two not out batsmen for England, having reached stumps on the second day unbeaten on 59 and 42 respectively.

Their partnership of 93 had helped the hosts out of an early hole, Dom Sibley having departed for a duck at the start of the fourth over before Zak Crawley then fell soon after for two, leaving the score at 18-2.

Devon Conway had starred for New Zealand with the bat, the debutant becoming just the seventh player to register a double hundred on debut in Test cricket as he made exactly 200. 

After Lord's, the teams will move on to Edgbaston to conclude the two-match series, though the Black Caps will remain in England as they take on India in the ICC Test Championship final later in June.

Trent Alexander-Arnold says he is "absolutely gutted" to miss England's Euro 2020 campaign after suffering a thigh injury against Austria on Wednesday.

The Liverpool full-back was the centre of heated speculation ahead of Gareth Southgate's decision to cut his preliminary squad to a selection of 26 this week.

Alexander-Arnold was picked, though, along with three other recognised right-backs in Kyle Walker, Reece James and Kieran Trippier.

However, the 22-year-old will play no part in the competition having gone off injured late on in the 1-0 friendly win over Austria after clearing the ball.

Alexander-Arnold, who faces around six weeks on the sidelines, posted an image on his Twitter account on Friday with the caption: "Absolutely gutted." 

Southgate will not confirm a replacement until after Sunday's friendly against Romania.

Chelsea have exercised the option to extend Thiago Silva's contract, meaning the defender will remain with the Premier League club for a further year.

The Brazil international was signed on a free transfer ahead of the 2020-21 campaign after leaving Paris Saint-Germain, making 34 appearances in all competitions for the Blues.

Silva started in the Champions League final against Manchester City but was forced off late in the first half through injury, leaving him to watch from the sidelines as his team-mates clinched a 1-0 triumph in Porto to secure the trophy for a second time.

The 36-year-old will now be staying at Stamford Bridge for the 2021-22 season to continue working under Thomas Tuchel, who has himself committed his future to Chelsea by signing a new deal that runs through to 2024.

"When we brought Thiago Silva in last summer, we knew we were adding a world-class player to the squad," Chelsea director Marina Granovskaia said.

"Thiago has duly shown everyone at Chelsea his immense quality throughout this season, and he has had a huge influence on and off the pitch for us.

"We said when he signed that we hoped Thiago would add new trophies to his impressive list of honours, and he has done just that with our success in the Champions League this weekend. We now hope that he carries on in exactly the same fashion in the coming year."

Eric Maxim Choupo-Moting has signed a new two-year contract with Bundesliga champions Bayern Munich. 

Choupo-Moting, 32, joined Bayern in October 2020 after spending two seasons with Ligue 1 giants Paris Saint-Germain, initially signing a one-year deal.  

The striker made 32 appearances in all competitions in his maiden season with the club – only 13 of which were starts – and scored nine goals. 

Choupo-Moting, who will play under new head coach Julien Nagelsmann next term after Hansi Flick left to take the Germany job, said: "I am proud to be here. FC Bayern is a very special club; the number one club in Germany and also one of the best clubs in the world. 

"My first year here was great. On the pitch, but also off the pitch, we had a lot of fun together. I want to continue to have success with the team. I'd like to reach the DFB-Pokal final in Berlin and ideally win the Champions League." 

Board member for sport Hasan Salihamidzic added: "We are happy that Maxim will stay with us for another two years. 

"He is a very important player for us, performing strongly last season and scoring many goals. Maxim can be used in several positions, has very good technique, a lot of experience and is a goal threat. 

"Aside from his sporting quality, Maxim is also important for our team as a person. He will help us achieve our goals in the next two years."

LeBron James has ruled himself out of competing for the United States at the upcoming Olympic Games in Tokyo. 

The 36-year-old Los Angeles Lakers star has represented his country at three Olympics, but he did not feature at Rio 2016. 

Earlier this year James had suggested he was considering playing for the USA in Tokyo.

However, following the Lakers' first-round playoff series defeat to the Phoenix Suns on Thursday, he said he would instead spend the next few months promoting his new movie 'Space Jam: A New Legacy', which is scheduled to open in July. 

Asked if the Olympics were a possibility for him, James said: "Nah, I think I'm gonna play for the Tune Squad [the name of the team in the film] this summer instead of the Olympics.

"I think that's what my focus is on, on trying to beat the Monstars – or the Goon Squad we call them now.

"I didn't have much success versus the Suns, so now I am gearing my attention to the Goon Squad here in July, in mid-July.

"So I'm going to let the ankle rest for about a month and then I'm going to gear up with Lola, Taz, Granny, Bugs and the rest of the crew. So, hopefully I'll see you all at the match."

Asked how the Lakers' early exit – the first time James has been on a losing side in a first-round playoff series in his NBA career – would benefit his body, he said: "It's going to work wonders for me. Obviously during the season I don't talk about rest, I don't even like to put my mind in that frame, it makes me weak.

"But in the off-season I've got an opportunity to rest. I've got like three months to recalibrate, get my ankle back to 100 per cent, where it was before that Atlanta game.

"That's the most important thing for me. Everything else feels extremely well. My ankle was the only thing that was bothering me in the latter stages of the season.

"It never fully got back to before the injury. But I'm happy I was able to go out there and at least try to help our team win."

Rio Ferdinand has questioned Gareth Southgate's decision to include Harry Maguire in England's Euro 2020 squad and says Marcus Rashford should not be considered for a starting spot.

Maguire was this week named as part of England's final 26-man squad for the tournament, despite missing Manchester United's final five games of the season – including the Europa League final loss to Villarreal – with ankle ligament damage.

He has yet to take part in training since linking up with his Three Lions team-mates, with Southgate admitting on Tuesday he is unsure if the defender will be ready for the Group D opener against Croatia on June 13.

With fears Maguire may not be fit enough to play any part in the group phase, former United centre-back Ferdinand does not believe Maguire should have been selected at the expense of another defender.

"Harry is important from set-pieces, as he showed at the World Cup. But I have to be honest, I wouldn't take players that are 50 per cent fit," said Ferdinand, who was speaking to Stats Perform on behalf of Heineken, an official UEFA Euro 2020 partner. 

"If I'm worried about a player being able to make 90 minutes, I wouldn't take them. Too much energy goes into talking about it and worrying about it, that it takes the focus off what you are there for as a team."

Who to play alongside John Stones in the heart of defence should Maguire fail to win his fitness battle is not the only big selection call Southgate has to make ahead of Euro 2020 getting under way next week.

The England boss is spoiled for choice in the final third, with Rashford, Raheem Sterling, Jack Grealish, Jadon Sancho, Bukayo Saka, Mason Mount, Phil Foden and Dominic Calvert-Lewin all battling for starting spots alongside captain Harry Kane.

Rashford has scored four goals in his last five appearances for England, but he struggled with a niggling injury issue towards the end of last season and Ferdinand would hold off from using the versatile forward until later in the tournament.

"If you're looking at form, I think Marcus probably doesn't deserve to start," Ferdinand said. "I think of the players around him in that position, Sancho and Foden should be picked in terms of form.

"I don't know much about Gareth's relationship with them players and what they've done in the past for him, and his confidence in certain players. Also, tactically how the game looks, who he is going to play. 

"In terms of form, I think he's scored one in nine or 10 games at the end of the season [for United]. I think he's a bit fatigued and I think he's been carrying a few injuries. I'd like to see him recuperating in this little period of time off, and then come into it fresh."

Of those eight players vying for a starting role in the final third, Aston Villa playmaker Grealish and Borussia Dortmund's Sancho lead the way in terms of big chances created in the league during the 2020-21 campaign with 14 each.

Despite missing 12 matches, Grealish was by far and away the most fouled player in the Premier League last season (110 fouls won), while his 2.68 dribbles completed per 90 minutes was bettered by just six players to have played at least 20 times.

Only Belgium (40) scored more goals than England's 37 in qualifying for Euro 2020 and Ferdinand is particularly excited by the attacking options available to choose from.

"In terms of wide players, we must have some of the biggest talent," he said. "We've got Foden, Sterling, Rashford, Grealish, Sancho, and Mount can play there as well – so six of the most talented, impactful players that are playing at the moment. 

"You look at Sancho, over the last three years has got 30 goal involvements every year, which is astounding for a kid who had been 21 and under. 

"Jack Grealish has been one of the hardest to combat players in the Premier League when he's fit. Phil Foden is deciding games in Champions League knockout stages, for one so young, and Man City are dominating in midfield. 

"It's crazy. You've also got Sterling, with what he's done over the last three years, his trophy haul that he's building at the moment is up there with the best. Those young players, it's mouthwatering."

While a number of positions are up for debate, it is certain that captain Kane – who topped the scoring charts in qualifying – will lead the line for the Three Lions.

Kane won his third Golden Boot after scoring 23 times in 2020-21, becoming the third player after Thierry Henry (four) and Alan Shearer to achieve such a feat.

He also set up 14 goals to become just the second player in the Premier League era to top the charts for both goals and assists (also Andy Cole in 1993-94).

The Tottenham striker's future is a hot topic of debate heading into the tournament after recently admitting he is at a "crossroads" in his career, but Ferdinand does not expect that to have any sort of impact on his performances.

"It happens to the best players," he said. "These players we're talking about with speculation, like Sancho and Kane, they have this every day of the week. This is normal for them, they are just in a tournament, that's the only difference.

"I think Harry has shown he enjoys wearing the armband. He enjoys the responsibility, some players grow with it. This tournament, I'd like to see that."

Ferdinand was speaking as part of Heineken's 'Enjoy the Rivalry' campaign, which encourages fans to watch Euro 2020 matches alongside their rivals.

The United legend was pranked by fellow former pro Robbie Savage as part of the initiative, culminating in the ex-England international having his portrait draped in a flag of rivals Wales.

"I was a bit surprised, I've got to be honest," he said. "I was probably being a bit too polite because there were two young ladies in front of me and I didn't want to be... well I saw the Welsh flag and I thought what are these people playing at?

"They don't understand the rivalry that we have with Wales and all of a sudden they drape me in a Welsh flag. It was weird.

"I think 'finally together again to be rivals', is a perfect strapline. I think everyone's waited for this opportunity, to have some sort of rivalry with teams, with people, with individuals."

The Blues beat the Reds 31-24 in Brisbane on Friday to stay top of the Super Rugby Trans-Tasman table.

Leon MacDonald's side have now won four out of four in the competition, though they were denied a precious bonus point at Suncorp Stadium against the injury-plagued Reds.

Harry Wilson found a gap to score the opening try of the match for the home team, but Brandon Paenga-Amosa's yellow card for collapsing a maul proved to be a turning point.

Dalton Papalii and winger Mark Telea crossed over for the Blues in the space of seven minutes as MacDonald's charges took full advantage of the one-man advantage.

Patrick Tuipulotu and Finlay Christie were next to dot down for the leaders, either side of Paenga-Amosa's try, to give their side a 17-point advantage.

The Reds made a fight of it late on when a crosskick sent Filipo Daugunu over, soon followed by a successful penalty from the Fiji-born winger, but the comeback fell just short.

The Blues are one point better off than Super Rugby Aotearoa champions the Crusaders, who also made it four wins from four by defeating the Western Force 29-21 in Christchurch.

Scott Robertson's side were made to work hard for the victory after falling behind to Toni Pulu's well-taken try inside the opening four minutes.

Manasa Mataele finished soon after and Will Jordan slid over to complete a quickfire turnaround for the Crusaders, who went further ahead thanks to Whetu Douglas.

Ollie Callan's score from close range looked to have given the Force some hope, only for Sione Havili to cross the whitewash after the half-time hooter had sounded.

Jordan got his second of the game to give the Crusaders a 15-point lead and they stayed strong at the back until the final seconds.

Jordan Olowofela chased down Kyle Godwin's kick and went over, denying the Crusaders a bonus point in the process.

Thomas Tuchel has signed a two-year contract extension with Chelsea after guiding the club to Champions League glory.

The German replaced Frank Lampard in the Stamford Bridge dugout in January, also leading Chelsea to the FA Cup final and into the top four of the Premier League in his first four months in charge.

Tuchel signed an 18-month deal with the Blues at the time, but he has been rewarded for his successful start to life in west London with a contract that runs through to the end of 2023-24.
