Iga Swiatek coasted through to the quarter-finals of the Ostrava Open after defeating Yulia Putintseva as Paula Badosa faltered against Anett Kontaveit.

Favourite Swiatek provided an astute performance to ease past Putintseva 6-4 6-4 to secure a potential quarter-final tie with Elena Rybakina.

Petra Kvitova, who is second seed in Croatia, did not enjoy as comfortable a victory but battled past Anastasia Potapova 6-1 6-7 (4-7) 6-3 to confirm her last-eight berth.

The ninth ranked Badosa, however, was not as fortunate as she was dumped out by Kontaveit, who cruised to a 6-3 6-4 win over the world number 27 in just over an hour.

Jelena Ostapenko set up a last-16 clash with fourth seed Maria Sakkari as she defeated Anna Blinkova 6-4 6-0, while Alison Riske recovered from a second-set setback to defeat Fiona Ferro 6-4 1-6 6-4.

Riske will now meet Jil Teichmann, who shocked former world number one Angelique Kerber, and whoever wins will be rewarded with a tie against world number 10 Kvitova.

Achraf Hakimi scored a last-gasp winner as Paris Saint-Germain maintained their 100 per cent record in dramatic fashion with a 2-1 vitory at Metz.

Hakimi had opened the scoring in the fifth minute, only for PSG to pegged back by Kiki Kouyate's 39th-minute header.

Deprived of Lionel Messi's services because of a knee injury, PSG looked to have run out of ideas, but Dylan Bronn's dismissal for a second yellow card set in motion a thrilling and fractious finish.

Metz coach Frederic Antonetti was sent off for his protestations and moments later Hakimi lashed the winner into the bottom corner in the 95th minute, prompting a furious response from Metz goalkeeper Alexandre Oukidja as PSG made it seven wins from seven.

A long evening appeared to be in store for Metz when PSG broke the deadlock in impressive fashion. Mauro Icardi's delicate chip was cleared off the line by Matthieu Udol, who could not repeat the feat to prevent Hakimi's follow-up from crossing the line.

Yet PSG failed to make the most of their first-half dominance. The visitors enjoyed three-quarters of the possession in the opening period but were pegged back from a set-piece as Kouyate met Lamine Gueye's corner with a powerful header that proved too strong for Keylor Navas.

Gueye could have completed the turnaround on the stroke of half-time, but he failed to find a way past Navas when sent through on goal by Ibrahima Niane.

Neymar fizzed an effort past the near post as PSG sought to regain their lead and the Brazil star was to the fore again when Hakimi blazed high across the face of goal from his clever lofted pass.

Kylian Mbappe almost caught Oukidja off his line with a long-range free-kick, and that should have been Metz's last scare. But there was a twist in the tale as captain Bronn received a second caution for time-wasting having kicked the ball away, with Hakimi cutting in and converting from another superb Neymar pass after Antonetti had seen red.

Wolves missed three penalties to hand Tottenham a 3-2 shoot-out victory following a 2-2 draw in Wednesday's EFL Cup third-round clash.

Tanguy Ndombele and Harry Kane fired Tottenham into a two-goal lead inside 23 minutes but Leander Dendoncker responded for Bruno Lage's men before the interval.

Daniel Podence levelled things up 13 minutes after the break following a mistake from Ndombele, but penalties were required at Molineux as neither side could find a late winner.

Pierluigi Gollini managed to save from Dendoncker and with both Conor Coady and Ruben Neves faltering, Spurs marched into the fourth round despite Pierre-Emile Hjobjerg missing.

Ndombele opened the scoring with 14 minutes gone, getting the better of Coady before drifting inside Willy Boly and slotting through John Ruddy's legs.

The visitors doubled their advantage nine minutes later, with Dele Alli carving open the Wolves defence before Kane drilled into the bottom-left corner.

However, Dendoncker halved Spurs' lead as he climbed the highest from Rayan Ait Nouri's outswinging corner to head into the top-right corner.

Alli and Kane attempted to link-up once more after half-time, but Ruddy was on hand to deny the former before Ndombele was at fault for Wolves' equaliser.

The France midfielder was caught in possession by Hwang Hee-chan, with Dendoncker subsequently finding Podence, who curled into the bottom-right corner to level.

Kane's header almost restored Spurs' lead but Ruddy's reflex save kept the scores level before Neves' deflected strike clipped the crossbar as the tie headed towards penalties.

Neves blasted over the fifth spot-kick after the first four had all converted before Dendoncker saw his low effort saved by the Spurs goalkeeper diving to his right.

Hojbjerg could have won it for the visitors but Ruddy denied the Denmark midfielder. However, that did not matter as Coady smashed into the crossbar to hand the away side their place in the fourth round.

Reece James was the hero as Chelsea overcame Aston Villa 4-3 on penalties after a 1-1 draw in the third round of the EFL Cup at Stamford Bridge on Wednesday. 

Ben Chilwell missed a chance to secure the win during the shoot-out after Ashley Young hit the bar and Kepa Arrizabalaga kept out Marvelous Nakamba, but James made no mistake to send Chelsea through. 

Villa were the better team for much of the first half but Timo Werner put Chelsea in front in the 54th minute with his first goal for the club this season and only his fifth of 2021. 

Cameron Archer – who scored a hat-trick against Barrow in the second round – guided in a stunning header to equalise 10 minutes later, only for Chelsea to show more composure at the spot and advance.

Milan moved level on points with Inter at the top of Serie A after Theo Hernandez came off the bench to inspire a 2-0 win over Venezia.

Stefano Pioli rung the changes following the draw with Juventus on Sunday and the Rossoneri endured a frustrating evening until Hernandez set up Brahim Diaz for the opening goal midway through the second half.

Neither side had registered a shot on target until Diaz volleyed home from point-blank range at San Siro on Wednesday, but Hernandez added a second goal to seal all three points.

Victory for Milan continued their impressive start to the Serie A season despite being depleted by injuries, with this their fourth win out of five matches without defeat.

Eddie Nketiah's delightful finish added gloss to a 3-0 win Arsenal were made to work hard for at home to AFC Wimbledon in the third round of the EFL Cup.

Arsenal had won their prior two matches – against Norwich City and Burnley – by just a single goal and looked to be heading for another narrow victory as they struggled to add to Alexandre Lacazette's early penalty.

A late flurry consisted of a vital second from Emile Smith Rowe and Nketiah's gorgeous flick, however, and Mikel Arteta's men have some momentum to carry into Sunday's derby against Tottenham.

Third-tier Wimbledon were far from embarrassed, although they must have feared the worst having conceded inside 11 minutes.

Nesta Guinness-Walker's rash lunge on Gabriel Martinelli on the right side of the penalty area gave Lacazette an opportunity from 12 yards, which he dispatched by sending Nikola Tzanev the wrong way.

But that goal was Arsenal's only shot on target of the first half, even if Tzanev almost gifted them a second when he palmed a looping ball against his own crossbar following Cedric Soares' corner.

A fierce Thomas Partey shot was pushed away after the break, while Nuno Tavares could only direct a far-post header against the upright.

Arteta was forced to bring on Smith Rowe and Bukayo Saka to put the game to bed, however, and the Arsenal number 10 found the breakthrough, prodding in after a scramble with Lacazette claiming the assist.

Nketiah's backheel took the game away from Wimbledon, before Saka twice came close to getting his own name on the scoresheet, whipping a first shot wide and finding Tzanev his match from the second.

West Ham sealed their first win at Old Trafford in 18 attempts as Manuel Lanzini's first-half goal secured a 1-0 win over Manchester United in the third round of the EFL Cup.

Both sides made wholesale changes from United's 2-1 Premier League win over the Hammers at the weekend, and it was David Moyes' men who settled quickest.

They deservedly went ahead after just nine minutes through Lanzini's first goal of the season, the Argentina international taking full advantage of some haphazard defending from the hosts.

Despite bringing on Mason Greenwood and Bruno Fernandes in the second half, United never really looked like clawing their way back into the game as the Hammers held on with relative ease. 

West Ham were rewarded for a bright start, Lanzini coolly stroking into Dean Henderson’s bottom-right corner from 10 yards following a fine run from Ryan Fredericks.

Juan Mata struck the crossbar from an acute angle soon after, while Anthony Martial saw an effort deflected wide as United looked to restore parity.

Alphonse Areola pawed away a long-range drive from Jesse Lingard as the Red Devils, who carved out 13 shots to West Ham’s four in the first half, ultimately failed to find a leveller before the break.

Ole Gunnar Solskjaer introduced Greenwood shortly after the hour mark and the teenager should have scored almost immediately, but his effort was kept out by the foot of Areola.

West Ham squandered two glorious chances in the closing stages, Andriy Yarmolenko inexplicably hitting the post with the goal at his mercy and Mark Noble firing straight at Henderson, but it mattered little in the end as the visitors ended United's EFL Cup run before it had even got going.

Lewis Hamilton is hanging on in the Formula One title race, but Mercedes are now ready to attack the 2021 run-in.

Seven-time champion Hamilton, chasing a record eighth crown, made a stunning start to the season, with three wins and a second-placed finish from the first four races.

In the 10 grands prix since, though, the Briton has taken the top spot of the podium just once, leaving him still waiting on his 100th win after a four-race drought.

Hamilton still entered the mid-season break with the championship lead, but a brutal triple-header saw him slip behind Max Verstappen, who recorded back-to-back triumphs before taking points in the sprint race at Monza, despite then crashing out alongside his rival.

Clashes between the pair have been frequent this year, but a short break before Sunday's Russian Grand Prix has allowed the contenders to focus again.

Mercedes team principal Toto Wolff said ahead of Sochi: "Our aim is to pull together a strong weekend, starting in FP1 and building one session at a time.

"Lewis is in the 10th championship battle of his F1 career, and he is laser focused on what he needs to deliver in the next eight races.

"As for Valtteri [Bottas], he's driving better than ever, like we saw in Monza – and he will be flat out every weekend.

"There's a calm determination about the team right now and the business end of a season, fighting for championships, is exactly what we enjoy the most."

Mercedes still lead the constructors' championship ahead of Red Bull.

LAST TIME OUT

Neither Verstappen nor Hamilton finished in Italy after a remarkable crash that saw the Dutchman's car land on top of his rival's halo.

Both drivers were forced to retire, with Hamilton telling of how he was "so grateful I am still here" and "incredibly blessed that someone was watching over me".

"I don't think I've ever been hit on the head by a car before," he said. "And it is quite a big shock for me."

With the two leading men ruled out, McLaren capitalised with a stunning one-two – their first since the 2010 Canadian GP.

Having just slipped behind rivals Ferrari in the standings, it was a huge result for the British outfit, as they moved back up to third.

WHAT TO EXPECT IN RUSSIA

It will be interesting to see how Verstappen and Hamilton approach this race, surely keen to avoid a repeat of Monza but also unable to risk taking their foot of the pedal in this tense tussle.

Mercedes have won every previous Russian GP, although they have been the outstanding team in each of those seasons. Now they face a real challenge.

The battle between McLaren and Ferrari is just as tense, although Bottas is maintaining a gap to Lando Norris after finishing third twice.

TOP FIVE OPTA FACTS

Mercedes dominant – With four wins for Hamilton, two for Bottas and one for Nico Rosberg, Mercedes have a 100 per cent record in Sochi. No team have won more races at a single grand prix without failing.

Hamilton at home – Hamilton has reached the podium in seven of his seven entries, registering a record four wins. His worst result was fourth in 2017.

Bottas from behind – Five of the seven winners have started on the front row, with Bottas' two victories after qualifying third the exceptions.

Ferrari frustration – Only in Abu Dhabi (12) have Ferrari made more appearances without winning ever than in Russia (seven). They have had two pole positions, two fastest laps and six podiums.

Tight at the top – The gap of five points between Verstappen and Hamilton is the closest the top two have been after 14 races since the 2016 battle between Hamilton and Rosberg (two points).

Matthijs de Ligt scored the decisive goal as Juventus came from behind to beat Spezia 3-2 and belatedly claim their first Serie A win of the season.

Failure to seal maximum points at Stadio Alberto Picco would have seen the Bianconeri go five games without a victory at the start of an Italian top-flight season for the first time since 1955-56.

Massimiliano Allegri's side went ahead through Moise Kean's first goal since he rejoined his boyhood club from Everton, yet Spezia stormed back through Emmanuel Gyasi and Janis Antiste either side of half-time.

Federico Chiesa restored parity with a fine goal, though, before De Ligt ensured a much-needed first win of the campaign with 18 minutes remaining.

The Bianconeri had deservedly taken the lead shortly before the half-hour mark, with Kean collecting Adrien Rabiot's knockdown and firing in off Jeroen Zoet's right-hand post from 18 yards.

It took the hosts just five minutes to respond, however, as Gyasi cut in from the left and fired across Wojciech Szczesny courtesy of a slight deflection.

Paulo Dybala forced a fingertip save from Zoet soon after – one of 11 first-half Juve attempts to Spezia's two – but the visitors fell behind four minutes after the interval when Antiste jinked inside Leonardo Bonucci after a swift counter-attack and clipped past Szczesny.

Zoet denied Kean and Dybala, as Juve desperately tried to claw their way back into the game, and the pressure told in the 66th minute when Chiesa fired in after superbly finding his way through the Spezia defence. 

De Ligt then lifted some of the clouds that had begun to gather over the Turin giants, powering past Zoet after a corner had fallen kindly to him, much to the relief of Allegri.

Derby County are facing a 12-point deduction in the Championship after going into administration.

Amid ongoing financial issues, it was confirmed last week that Derby had filed a notice of intention to appoint administrators.

Manager Wayne Rooney revealed he only found out after the news had broken in the media, while owner Mel Morris has claimed the club is losing between £1.3million and £1.5m per month.

The EFL said in a statement on Wednesday that "in accordance with EFL Regulations, a 12-point deduction has been immediately applied to Derby County Football Club's 2021-22 season total".

It added: "The League has already held initial constructive discussions with the administrators and will remain in regular dialogue with them as they seek to find the appropriate solutions required to assist the club as it navigates its way out of insolvency."

Derby also face the possibility of a further points deduction due to a possible breach of the EFL's Financial Fair Play rules.

Andrew Hosking, Carl Jackson and Andrew Andronikou of business advisory firm Quantuma have been appointed as the club's administrators.

"COVID-19 has had a significant impact on the finances of the club and its long-term ability to continue in its current form," a statement from Hosking, released on the club's official website, read.

"We recognise that with the commencement of the 2021-22 season last month, this news will be of concern to stakeholders and fans, in addition to the city of Derby and the wider football community.

"We are in the early stages of assessing the options available to the club and would invite any interested parties to come forward.

"Our immediate objectives are to ensure the club completes all its fixtures in the Championship this season and finding interested parties to safeguard the club and its employees."

Rooney just managed to guide two-time English champions Derby to safety on the final day of the Championship season in 2020-21.

However, there was a risk the Rams could still go down due to financial regulations, though instead they were fined £100,000 and ordered to resubmit their accounts by an EFL disciplinary commission.

Derby, who face Sheffield United on Saturday, beat Stoke City 2-1 in their previous match to move onto 10 points from eight games prior to the deduction.

Simona Halep has confirmed she has parted company with her long-time coach Darren Cahill.

Halep, who was the year-end number one in 2017 and 2018, has been coached by Cahill for the past six years.

She won the 2018 French Open, her first grand slam title, under his guidance before Cahill left the team for a spell to spend more time with his family.

Cahill – who also guided Halep to the 2018 Australian Open final – returned to coach the Romanian ahead of the 2019 WTA Finals, following on from her success at Wimbledon.

The 29-year-old has endured an injury-hit 2021 and was knocked out of the US Open in the fourth round by Elina Svitolina.

In a post on her official Twitter account, Halep announced: "After six wonderful years working together, Darren Cahill and I have decided that it's time to end our working relationship.

"Thank you D for everything, for making me a better tennis player and a better person."
