Andrey Rublev was pushed hard by Jeremy Chardy on Friday but eventually secured his 18th successive ATP 500 win to set up a semi-final meeting with Stefanos Tsitsipas at the Rotterdam Open.

Chardy managed to save match points in the second set, as Rublev wobbled at the crucial moment, but the Russian got the job done 7-6 (7-2) 6-7 (2-7) 6-4.

The pair were on court for just under two hours and 40 minutes and racked up a considerable number of winners, with Rublev's 44 eight more than the Frenchman.

His 18-match winning streak in ATP 500 events has only been bettered on five previous occasions since 2009, all of which were achieved by Andy Murray, Rafael Nadal or Roger Federer, who holds the record of 28 successive victories.

If he is to get any closer to Federer's remarkable haul, Rublev will have to go beyond Tsitsipas, but Friday's match took plenty out of him.

"I will try to do as much as I can to be ready for [the semi-final]… Stefanos also had two tough matches [this week]," said Rublev.

"He had three sets [on Thursday] and today he had three sets. Now he has to play doubles. It is not easy."

As Rublev alluded to, Tsitsipas certainly did not have it all his own way against another Russian, Karen Khachanov, coming from a set down to win 4-6 6-3 7-5.

Tsitsipas also had to contend with being 3-1 down in the third set – but Rublev knows all about the Greek's ability to come back from the brink having lost to him in last year's ATP Finals despite having match point.

"He [Khachanov] was playing great tennis and I wasn't sure if I would be able to compete," Tsitsipas said after the contest.

"I had an amazing 5-0 lead in the second set and that brought a lot of confidence into my game. We had great rallies and the quality of tennis was excellent. You need to stay as calm as possible in three-setters. I have won a lot in the past and with experience, it gives me an idea of how to play in these tight moments."

Borna Coric and Marton Fucsovics will go head-to-head in the other semi-final.

Croatian Coric came through in straight sets against Kei Nishikori, though it was by no means a straightforward victory as he was pushed to tie-breaks in both sets, winning 7-6 (7-2) 7-6 (7-4).

Fucsovics saw off Tommy Paul 6-4 6-3 to reach the last four.

Blake Griffin could be set to swap the team sitting at the bottom of the Eastern Conference standings for a potential title contender after reportedly agreeing a contract buyout with the Detroit Pistons. 

Stories on Friday of a parting of the ways between the Pistons and Griffin hardly came as a surprise, considering he had not featured for the team in their previous 10 games prior to the All-Star break. 

Both parties had agreed for the 31-year-old to be held off the active roster as the franchise worked towards a solution over his playing future.

With no trade able to be worked out, a settlement has instead been reached with Griffin – whose contract was due to run until the end of the 2021-22 season – that will see him become a much-coveted free agent. 

Now the six-time All-Star waits to see what offers come his way. According to Adrian Wojnarowski of ESPN, the Brooklyn Nets, Golden State Warriors, Miami Heat and Portland Trail Blazers are among those interested.

Griffin had averaged 12.3 points per game while shooting 36.5 per cent in his 20 outings for Detroit, who have found wins hard to come by in the 2020-21 campaign. 

Those figures are well down on his career numbers, though. After 642 games, he averages 21.4ppg, as well as 8.7 rebounds and a field goal percentage of 49.5 per cent. The only area of improvement this season has been free-throw success, landing 71 per cent compared to 69.5 per cent overall.

Selected with the first overall pick in the 2009 draft, Griffin spent his first eight seasons in the league with the Los Angeles Clippers, though his debut campaign was a write-off due to injury. 

However, he was named Rookie of the Year in 2011 after playing in all 82 games, making his first All-Star appearance and also winning the dunk contest. Further injury issues hampered his progress, yet the Clippers still gave him a five-year, $173million contract in July 2017. 

Just six months later, he was traded to the Pistons. Griffin was the leading piece in a six-player deal that also saw Detroit give up protected draft picks to acquire the power forward.

"Blake has been a great representative for our franchise and for the city of Detroit," Pistons owner Tom Gores said in a statement.

"His work ethic and his approach to the game contributed a lot to our culture. He has been a consummate pro and we wish him continued success. I'm grateful for everything he did for our team and for our community."

Petra Kvitova ended the run of qualifier Jessica Pegula to set up a 2018 final rematch against Garbine Muguruza at the Qatar Open. 

Kvitova saw off Pegula in straight sets, triumphing 6-4 6-4, meaning she will be involved in the final of the tournament for a third time in four years. 

Having twice let slip breaks in the opener, the 2020 runner up edged ahead again at 5-4 before serving out for a 1-0 lead. 

Pegula appeared set to draw level when she raced 3-0 ahead in the next, only to be pegged back by Kvitova, who hit 26 winners and the same number of unforced errors. Victory was eventually sealed after one hour and 18 minutes on court. 

The two-time Wimbledon champion secured the trophy in Doha three years ago by beating Muguruza, who did not even have to hit a ball to progress on Friday after opponent Victoria Azarenka withdrew from their semi-final due to a back injury. 

That title showdown in 2018 went the distance, Kvitova rallying after losing the opening set to eventually prevail. 

"I think it's going to be a tough match," Muguruza said, according to the WTA Tour's official website.  

"We played here in another final three years ago, so just looking forward to playing that match and hopefully getting the trophy." 

The Spaniard has been in impressive form this week, ending Aryna Sabalenka's hopes of defending her crown in the last 16 before thrashing Maria Sakkari in a lopsided quarter-final.

Meanwhile, in Friday's action at the Lyon Open, second seed Fiona Ferro rallied from a set down to beat fellow Frenchwoman Clara Burel and reach the semi-finals. 

Ferro's 2-6 6-1 6-3 triumph means she is certain to break into the top 40 in the world for the first time in her career.  

The only other seed left in the draw is Paula Badosa, the Spaniard knocking out Kristina Mladenovic. Her reward is a last-four clash with qualifier Clara Tauson, conqueror of Camila Giorgi in straight sets. 

George Russell hopes Williams can make a flying start to the Formula One season in Bahrain - but he believes Mercedes are the only team who will be sure they are race-ready.

British driver Russell caught the eye when he replaced Lewis Hamilton at Mercedes for one race last year, after the world champion tested positive for COVID-19 and missed the Sakhir Grand Prix.

He went close to winning that race until a pit-stop error and a puncture late on cost him a probable victory, and he then returned to his regular drive at Williams.

Mercedes have assured Russell, who is part of their junior driver programme, that he can have a racing future with them if his development continues as expected.

That could come as soon as next year, but for now Russell's focus is on delivering for Williams.

The team has been in transition following the takeover by Dorilton Capital, and German motorsport veteran Jost Capito was appointed chief executive officer during the close season.

Russell believes Williams, who failed to score a point last season, should be better placed in 2021 to at least improve on that disappointing outcome.

"We want, the bare minimum, to be fighting with the Haas and the Alfas, as we did last year, and closing the gap to that midfield," Williams said.

"We made nine out of 17 Q2 appearances and that is definitely a thrill. That's got to be almost an aim every weekend for myself and team."

The season begins in Bahrain on March 28, and by then there should be evidence of which teams have made progress since 2020, with testing taking place, also in Bahrain, on the March 12-14 long weekend.

Russell admits it is a waiting game to see how rivals have advanced, or regressed.

"Fingers crossed that they go backwards and we go forwards," he said, in an Instagram chat on Formula One's official page. 

"Ultimately, we may go to Bahrain and see every other team has progressed more than us.

"We may go there and see we've made great progress. Until we get to Bahrain not a single team, probably bar Mercedes, can tell you how they're going to perform."

Russell, 23, has been tipped for a big future in the sport. He also believes Williams, a great name from the history of Formula One, can begin a journey back to the top of the sport.

"The arrival of Jost is massive for the team, really exciting," he said. "The future for Williams and everybody here at Grove [the team's headquarters] is really great.

"Unfortunately, things don't change in a matter of moments in Formula One, but the building blocks are really getting set in stone.

"Jost has loads of experience, he's a great character, and I think he's going to bring a lot of motivation to the team."

Russell was speaking on the day F1 chiefs confirmed the Portuguese Grand Prix on the new season's calendar, with the race inked in for May 2.

It will be the second round of 23 in the championship, with Portugal having returned to the Formula One rota last year for the first time since 1996.

Lionel Messi's inspirational form through February has seen the Barcelona captain collect his first Player of the Month award of the season.

February was Messi's most fruitful month of the 2020-21 campaign to date as he scored seven goals, two more than he managed in January.

No player scored more than him, while Real Sociedad's Alexander Isak was the only other individual to net more than four times in the month.

Messi's goalscoring habits helped Barca win four of their five games in the qualifying period, all of which saw him score at least once.

As such, Barca have improved their chances of potentially sparking a genuine title scrap in the final months of the season, with the Blaugrana only five points adrift of the leaders Atletico Madrid.

While Diego Simeone's men do still have a game in hand, Los Colchoneros also have the tricky test of a derby clash with Real Madrid to look forward to this weekend.

Messi's commitment to the cause was questioned earlier in the campaign after he rocked the club in pre-season with his transfer request.

He had only scored four times heading into December, when he added a further three – he already has 12 in 2021 and sits atop the 'Pichichi' standings with 19, three clear of nearest rival and friend Luis Suarez.

Messi is only the second Barcelona player to win the award this term, with Ansu Fati – who has missed much of 2020-21 through injury – claiming it for September.

Ronald Koeman's captain saw off competition from Isak, Yassine Bounou, Thibaut Courtois, Alex Berenguer, Nabil Fekir and Jose Luis Morales to win the prize.

George Russell has no intention of "hassling" Mercedes over his future as he focuses on trying to get the most out of a new-look Williams car in 2021.  

The British driver is heading into the final year of his contract with Williams, where he will once again work alongside Nicholas Latifi for the season.  

It will be a third year for Russell with the team, though he did step in to drive for Mercedes - having previously been part of their junior driver programme - at the 2020 Sakhir Grand Prix, replacing Lewis Hamilton after the seven-time world champion tested positive for COVID-19. 

His performance in the race - he was in front for the majority before a slow puncture forced him to settle for ninth place - led to speculation over a permanent switch, but Hamilton and Valtteri Bottas have remained together.  

While a move could still happen at some stage further down the line, Russell is relaxed over his standing within Mercedes.  

"Mercedes and Toto have always had my back and believed in me from day one. When they believe the time is right, the time will be right," he told Sky Sports at the launch of Williams' FW43B car.  

"I'm not hassling them, I’m just going out there and doing my job on the track. What comes in the future will come.  

"Obviously I had a great opportunity in Bahrain last year, but for now we will focus on the job here at Williams for this season and trying to get the most out of it."

In a somewhat surprising move, Hamilton only agreed to a one-year extension earlier this year, committing him to a ninth season with Mercedes.

Bottas' deal runs "at last until the end of 2021", per the team's statement when the Finn's future was revealed last August, so Russell could potentially be considered to replace either driver in 2022.

"Every driver wants to put themselves against the best," he said when asked if forming a partnership with Hamilton appealed to him.

"I believe in myself and Lewis is the benchmark at the moment, but equally you have a lot of fantastic drivers out there who might not have the same CV as Lewis.  

"Max [Verstappen], Charles [Leclerc], Lewis – they are all on the same level. Putting yourself against one of those three would be great for any driver."

Williams - now owned by Dorilton Capital - unveiled a new blue, white and yellow livery on Friday that takes inspiration from the team's successful cars in the 1980s and 1990s.

Rishabh Pant has revealed he took on a jaw-dropping reverse sweep against James Anderson because he felt it was a day when he could do no wrong.

Test cricket's most prolific pace bowler was staggered to be carved away to the boundary in such an unorthodox manner, as India got the better of England on day two in Ahmedabad.

Anderson had only just taken the new ball and had seen it already thrashed to the boundary by Pant from successive balls.

On his way to 101, Pant decided the moment was ripe to paddle Anderson over the England slips for one of the most remarkable shots likely to be played in a Test.

The fourth and final match of the series is leaning heavily India's way after they reached the close on 294-7, with a first-innings lead of 89 runs. 

Pant said of his special shot: "You have to premeditate that, but when everything is going your way you can try your luck sometimes."

Quoted in the Times of India, he said: "I get the license most of the time, but I have to assess the situation and take the game head on. I like to make the team win and if the crowd is entertained by that, I'm happy."

Pant came to the crease with India in trouble on 80-4, and they were also stumbling at 146-6, but his alliance with Washington Sundar (60 not out) turned the momentum of the game.

Anderson eventually took revenge, having Pant caught by Joe Root to end a 118-ball innings, but it was the batsman's day after he began with a cautious approach.

"If the bowlers are bowling well, respect it and take the singles, and that was on my mind," Pant said. "I like to play the situation and I just see the ball and react - that's the USP of my game.

"The team plan was to get to 206, past the England total, and then get as many runs as possible after that as a batting unit."

England are confident spinner Dom Bess will rediscover his rhythm after being left frazzled by India's batsman and his own wayward line on day two of the fourth Test.

India reached 294-7 thanks to a stunning 115-ball century from Rishabh Pant, who helped the hosts establish an 89-run lead, after surviving a big lbw shout from Bess shortly before tea.

Bess finished without reward, with figures of 0-56 in 15 overs pointing to a lack of threat from the 23-year-old off-spinner. He bowled with a lack of control at times, throwing in far too many full tosses, and will want to get among the wickets on Saturday morning and put a bad Friday behind him.

He was recalled for this contest in Ahmedabad having been left out for the second and third Tests, both of which England lost after making a winning start to the series in Chennai.

England spin coach Jeetan Patel said Bess had "needed a break" and was "jaded" by his experience of that opening match.

But Patel trusts Bess is capable of troubling batsmen again, and said of his disappointing performance so far in this match: "It's no real one thing, it's just a fact it didn't work out for him today.

"There's still room for him to improve, like everyone in this group, but Bessy's still very young. He's still learning how to bowl red ball at Test level which is very difficult. He'll be better for these experiences going forward.

"There's some things with Bessy that we'd like to get into. He's got time after this Test match to get back and look at that, but right now he's got a job to do and that's getting those three wickets tomorrow.

"He would have liked to have bowled a lot better today and liked to have given a lot more to the group, and it didn't work out for him. They played him very well. They sat on him and looked for balls to score off when they could.

"Right now he will be quite down and quite tired, but the beauty of this game is the fact there is another opportunity tomorrow."

Ben Stokes, by contrast, was hailed as England's 'Superman' by Patel. 

Stokes took 2-73 in 22 overs to follow up his 55 with the bat on Thursday, and at stumps he appeared exhausted, having been running in amid searing heat.

"Stokesy's your man. He's the guy you want to go to for anything really," Patel said. "He's almost like a Superman with this sort of stuff. He really does enjoy the tough battles.

"He bowled a lot of overs today. He almost bowled the whole first session and he got some crucial wickets for us on the way.

"He's pretty cooked as you can imagine, but he's a warhorse and he loves it. He loves when it gets tough and he loves when it gets hot and tiring, and that's when he stands up most. Hopefully we see the best of him again tomorrow."

Patel said Pant's innings was "pretty special" but claimed the match was "still quite in the balance".

"He came out after that tea break and took it to us," Patel said of Pant's effort. "Hats have to go off to how they played that."

Bayern Munich coach Hansi Flick made no secret of his admiration for Borussia Dortmund's Erling Haaland ahead of Der Klassiker, backing the Norway international to dominate the future of the sport.

Haaland has enjoyed a rapid rise since establishing himself as first choice at Salzburg for the start of the 2019-20 season, his remarkable haul of 28 goals in just 20 matches for the Austrians propelling him to top of many big clubs' transfer shortlists.

But, while the likes of Manchester United were keen on Haaland, Dortmund persuaded him to make the move to Signal Iduna Park, where he has been an overwhelming success.

In 45 matches across all competitions, Haaland has 43 goals, while he outperformed his xG (expected goals) by 4.2 in the second half of 2019-20 after joining Dortmund, meaning not only is he scoring frequently but he is also finishing more difficult opportunities – by comparison, Robert Lewandowski has not boasted such a strong xG differential since 2016-17 (7.8).

In three previous games against Bayern – two in the Bundesliga and one in the DFL-Supercup – Haaland has two goals, but he is yet to end up on the winning side against them with BVB.

Nevertheless, Flick is well aware of the threat posed by the Molde youth product, with Bayern facing the prospect of potentially being replaced at the Bundesliga summit by RB Leipzig if Dortmund leave the Allianz Arena with all three points on Saturday.

"Haaland is what a centre-forward has to be," Flick said.

"He has an enormous hunger for goals. The future could belong to him because he has everything he needs for it.

"He's fast, has a strong finish and the right mentality. When you see the intensity with which he puts on a sprint over 80 metres – it's great. He's someone you always have to watch out for.

"It's very important to close the spaces for him. We have to cut off those passes to him."

Flick was also asked about the situation of backup goalkeeper Alexander Nubel, who arrived on a free transfer from Schalke last year having established himself as one of the world's most-promising young goalkeepers.

It was always seen as a potentially risky move for Nubel given the presence of Manuel Neuer, who has gone on to put his injury nightmares behind him and once again cement himself as Bayern's number one.

Nubel's agent recently underlined his client's frustration with the situation and suggested he would look to secure a loan move away from Bayern if things did not change, and Flick showed little sympathy in his response.

"Those are things that we talk about internally – we will have an exchange," Flick said. "But we have no business talking about that here.

"His point of view is his right. Alex knew what he was getting into when he came to Bayern Munich. My job as coach is to pick the players who are currently the best team. He played two games and now he's injured.

"The clear number one is Manuel Neuer."

Jamal Musiala has signed his first professional contract with Bayern Munich.

The rising Germany star has pledged his future to the Bundesliga champions until 2026, just a week after turning 18.

Musiala has made swift progress since joining from Chelsea two years ago and has made 26 appearances in all competitions this season for Hansi Flick's side.

At 17 years and 363 days old, he became Bayern's youngest Champions League goalscorer when he netted in the 4-1 last-16 first-leg win over Lazio.

"I'm really pleased to have signed my first professional contract at FC Bayern," Musiala said via the club's website. "I just feel very good at the club and in the team, I'm playing with the best players in the world and I can learn from them every day in training.

"Hansi Flick, [sporting director] Hasan Salihamidzic and [chief scout] Marco Neppe, along with the whole club, have believed in me and given me the chance very early on.

"I just want to repay that faith with good performances, keep getting better and win a lot more titles with FC Bayern. My aim is to become an important player for this club."

Salihamidzic said: "We're very happy that Jamal has decided to sign his first professional contract at FC Bayern on a long-term basis. This has been a joint effort.

"Before Jamal came to FC Bayern in summer 2019, we had to and were able to convince him and his family about our project. I am very pleased that our system of finding talented players, developing them and then integrating them into the first team is bearing fruit.

"Our chief scout Marco Neppe has played a significant role here. Now we must all ensure that Jamal continues to be nurtured and challenged. I am sure that he will bring a lot of joy to FC Bayern."

Musiala, who last month declared he will play for Germany at senior international level, has been tipped for a call-up to Joachim Low's squad for the coming international break.
