Barcelona took a "giant step" towards a successful season with a thrilling comeback win over Granada, Ronald Koeman said.

The Catalans claimed a remarkable 5-3 Copa del Rey quarter-final win on Wednesday after forcing extra time at Estadio Nuevo Los Carmenes.

Barca were trailing 2-0 as late as the 87th minute only for Antoine Griezmann and Jordi Alba to force the additional period, after Francisco Trincao, Lionel Messi and Ousmane Dembele had all hit the woodwork.

Griezmann made it 3-2 only for a Fede Vico penalty to level matters again, but Frenkie de Jong scored from a rebound and Alba smashed home a stunning volley to secure Barca's semi-final spot.

Koeman last week suggested his side were not ready to compete for the biggest trophies and the Barca boss remains unconvinced they could end 2020-21 winning LaLiga, the Copa and the Champions League.

However, he believes their fightback against Diego Martinez's side could perhaps be a turning point in their campaign.

He said: "I was referring to winning the three trophies: LaLiga, the Champions League and the Copa. I don't believe [we can win all three]. But I've always believed in the team. We've improved many things, above all in character. We've taken a giant step forward.

"It helps to have spirit and strength in the team. That's the way. We've worked a lot to get to the moment when the team starts to believe and it's a proud feeling. And it's come at an important moment of the season.

"We started the game really strongly, we played really well in the first 20 minutes. A mistake in playing where we shouldn't be playing cost us a goal.

"You have to highlight the team's mentality because we never gave up. We had really bad luck with the woodwork. We did everything to win the game.

"We deserved it due to the mentality of the team, but on this occasion, we showed we know how to suffer. We knew how to defend the result and we deserved the win."

Griezmann proved pivotal to the result, scoring Barca's first before setting up Alba's equaliser with a cushioned header from a Messi cross.

The France star then converted an emphatic header of his own and teed up Alba's spectacular second with a clever outside-of-the-foot pass.

It was the first time the €120million man had been directly involved in four goals in the same game for the Catalans.

"I'm really pleased with Griezmann," said Koeman. "I know it's really important for him. The team needs him. With his effectiveness, we're more dangerous."

Paris Saint-Germain returned to winning ways in Ligue 1 with a 3-0 victory over bottom side Nimes at the Parc des Princes on Wednesday. 

The champions suffered a shock 3-2 loss to lowly Lorient on Sunday - their first defeat under Mauricio Pochettino - but responded with a comfortable victory on home soil. 

Star man Angel Di Maria profited from a terrible Lamine Fomba error to open the scoring and then crossed for Pablo Sarabia to add a second before half-time. 

Kylian Mbappe scored a stunning third goal for PSG, who were without the suspended Neymar, but they remain third in the table as leaders Lille and second-place Lyon also triumphed.

Moise Kean clipped the outside of the post with a header from 10 yards but PSG were ahead seven minutes later through Di Maria's composed finish. 

Nimes midfielder Fomba played the ball straight to Di Maria's feet and the Argentina international fired away from Baptiste Reynet after teeing himself up. 

The home side nearly had a second soon after when Presnel Kimpembe headed a corner back across goal and Thilo Kehrer turned it against the underside of the crossbar. 

But Sarabia did manage to double his team's tally nine minutes before the interval, heading Di Maria's right-sided cross into the bottom-right corner from five yards. 

Fomba was denied by Sergio Rico as he tried to make amends for his earlier error, while Anthony Briancon and Renaud Ripart also had attempts saved by the stand-in PSG keeper. 

Nimes continued to ask questions of their opponents but the game was put out of their reach by Mbappe, who curled a shot past a stranded Reynet to seal the win. 

Atalanta were unable to make the most of their superiority as they were held to a 0-0 draw at Napoli in the first leg of their Coppa Italia semi-final, with David Ospina keeping the visitors at bay.

Gian Piero Gasperini's men were in control for much of the game and created the best chances of the match, but they ultimately had to settle for a draw ahead of the return leg in Bergamo next week.

Luis Muriel was Atalanta's danger man, proving a real nuisance to Napoli as he offered a threat in front of goal and also proved an able creator, though Ospina in the home side's net stood firm.

Napoli might have been expected to produce an improvement after the interval but still they struggled to craft openings of their own, consigning them to an underwhelming 0-0 first-leg draw.

Although Napoli looked bright at first, Atalanta soon became the dominant force and went close to a fluke early lead when Muriel's wicked free-kick delivery from the left drew a desperate save from his compatriot Ospina in the hosts' net.

The excellent Muriel was involved again soon after as he fed Matteo Pessina into the box, but Ospina saved at his feet and Rafael Toloi hopelessly shot wide a few minutes later following a clever one-two.

Muriel then wasted a decent chance of his own late in the half, blazing over from just inside the area after cleverly evading Kalidou Koulibaly.

Ospina remained busy at the start of the second period as he first rushed out to thwart Muriel, before holding on to Joakim Maehle's excellent header from a corner just past the hour.

Napoli's midfield presence diminished considerably as they lost Diego Demme and Lorenzo Insigne in quick succession to knocks, with Atalanta's dominance increasing as a result.

But Robin Gosens missed a glorious chance as he headed wide 13 minutes from time and that proved to be their final opportunity.

Josh Adams has been suspended for Wales' Six Nations games against Ireland and Scotland after breaching COVID-19 protocols.

Wayne Pivac's squad were released from their training camp on Saturday and wing Adams attended a gathering the following day, where his immediate family were present.

That breach of the rules came to light when the squad returned for international duty on Tuesday, with Adams missing Wales' first Six Nations game against Ireland at the Principality Stadium on Sunday and the trip to Murrayfield six days later.

Adams said: "I would like to apologise unreservedly. When out of camp, at the weekend, I made an error of judgement. I attended a small gathering of immediate family to celebrate a family milestone.

"It was wrong to do this. I'm aware that everyone needs to follow the rules and being in the public eye I have a responsibility to lead by example and I've fallen short on this occasion.

"I'd like to apologise to my team-mates and to our supporters for my mistake."

Wales head coach Pivac said: "We are extremely disappointed with the breach and have acted robustly and swiftly to take all appropriate measures.

"All players and management have received detailed briefings and education regarding our protocols, and everyone has a responsibility to abide by the rules.

"On this occasion, Josh has made an error of judgement, he made a mistake and he has shown immediate remorse. He was present at a small, immediate family gathering to celebrate a milestone with those close to him but that is against the rules and action had to be taken.

"All members of the national squad have received extensive COVID-19 protocol briefings and education. We will continue with our programme, which has been very effective to date, and remind everyone of their responsibility to not only adhere to the extensive measures in place but also to set an example.

"We will work with Josh in relation to his integration back into camp following a further testing and re-education process."

England batsman Zak Crawley is a doubt for the first Test against India after suffering a wrist injury. 

Crawley slipped outside the dressing room in Chennai on Tuesday and it is feared he may have suffered a fracture just three days before England start a four-match series with Virat Kohli's side. 

He must now wait for scan results to discover the extent of the injury, which he suffered on the eve of his 23rd birthday. 

An England and Wales Cricket Board statement said: "Zak Crawley did not train today at England's practice session in Chennai. 

"He slipped outside the dressing room yesterday (Tuesday) and has injured his right wrist. 

"We are waiting on the results of scans and will know more tomorrow, ahead of our final practice. There is nothing further to add at this stage." 

Crawley opened in Sri Lanka in the absence of Rory Burns, but looked set to move to number three at M. A. Chidambaram Stadium after Jonny Bairstow was rested. 

England will have to rethink the order if he is unavailable, although there was positive news over Ollie Pope, who has recovered from a shoulder injury and could make his comeback after being added to the squad.

South Africa will want to avoid being on the wrong end of a series sweep as they aim to end a barren run in Asia when they go up against Pakistan in the second Test. 

Having suffered a seven-wicket defeat in Rawalpindi, the Proteas are now winless in their previous 13 Tests on the subcontinent, a dismal run of form that followed a 153-run victory over Sri Lanka in Galle in July 2014. 

The tourists were undone by Pakistan's spin pairing of Yasir Shah and Nauman Ali in the first game, with the duo taking 14 of the 20 South Africa wickets to fall at the National Stadium. 

However, the venue for the second Test could offer a little more help to the quicker bowlers, a welcome boost for struggling South Africa as they bid to draw level. 

Their plans for the first Test were hampered by the late withdrawal of Tabraiz Shamsi, who suffered a back issue in the warm-up and had to be replaced by paceman Lungi Ngidi.  

Shamsi has recovered in time to be considered for selection, while opening batsman Dean Elgar is also fit to play after a taking a nasty blow to the hand while batting in his team's second innings. 

South Africa fought hard in the face of a hefty first-innings deficit but were left with too much to do after only making 220 on day one. Amid the frustration, all the top seven in the order reached double figures but failed to build on it, their cause not helped by both Rassie van der Dussen and Temba Bavuma getting run out. 

As for the hosts, their line-up may well depend on the pitch. Considering the balance of the side worked so well last time out, it could be they go with the same XI again. 

The top order did struggle but Fawad Alam's century and a wagging tail helped rescue their first innings, having at one stage slumped to 27-4 late on day one. Babar Azam had a quiet debut in his role as Test captain in terms of his output with the bat, managing 37 runs in his two knocks.

CAPTAINCY SWANSONG FOR DE KOCK? 

It appears Quinton de Kock is set for his final Test in charge of the Proteas – for now at least. The wicketkeeper-batsman may have been set to continue in the role for the Tests against Australia on home soil, but that series has been postponed. Instead, the break will allow De Kock to get some well-earned rest and team management to assess their options. 

"When we get back after this tour we've got a bit of time before our next series so we can sit down and make a good, solid call on who can take over from him and release him from that burden and try and get the best out of him," South Africa coach Mark Boucher said on the eve of the game. 

 
SPINNERS IN SIGHT FOR YASIR 

Yasir played a pivotal role in the opener, finishing with match figures of 7-133. His haul in Karachi takes his career tally in Tests to 234 wickets, meaning he is just three shy of fifth place on the all-time list for Pakistan.  

The great Abdul Qadir currently occupies the spot, while another leg-spinner in Danish Kaneria sits third on 261. However, there is some way to go to catch the bowler on top; Wasim Akram finished his career with 414 wickets at a ridiculously impressive average of 23.62.  

KEY MATCH FACTS

- South Africa will be looking to avoid a fourth consecutive multi-game Test series loss away from home; it would be the first time the Proteas have lost as many such series in succession since losing each of their first seven in the format (July 1907 – February 1932).

- Pakistan won their most recent Test at Rawalpindi Cricket Stadium by an innings and 44 runs (against Bangladesh, February 2020). They will be aiming to secure back-to-back triumphs at the venue for the first time.

- Babar Azam has scored a century in each of his previous two Test innings in Rawalpindi; no player has more at the venue in the format (Saeed Anwar and Michael Slater also have two).

- Pakistan have dropped 13 catches in Tests so far this year, the most by any side and one of only two in double figures (India – 10).

- Kagiso Rabada has a bowling strike rate of 41.1 in Test cricket, the best by any player to take at least 150 wickets in the format.

- Faheem Ashraf finished with the best dot ball percentage (89.3 per cent) of any bowler in the first Test, though it was the first time he has failed to claim a wicket.

Bayern Munich are still waiting on Leon Goretzka and Javi Martinez to return negative coronavirus tests so they can resume first-team duties.

The midfield duo are set to be absent once again for Friday's Bundesliga match at Hertha Berlin after testing positive for COVID-19 last week.

Speaking at a pre-match news conference, head coach Hansi Flick confirmed Martinez's spell of self-isolation is set to end on Wednesday, with Goretzka having to wait until Friday.

After the Hertha game, European champions Bayern will fly to Qatar to commence their Club World Cup campaign.

"With Javi and Leon it is the case that we do a test after the quarantine, I can't comment on that because I don't have the results," he said.

"Javi has to take the test and then it will be determined if he still has the virus in his body. We have to wait from day to day.

"We also know with Leon that it takes a few days longer. He also has to be tested, everything will depend on that."

With or without Goretzka and Martinez, Flick conceded the Club World Cup will place an additional strain upon Bayern within an already condensed schedule.

"Qatar is very stressful, we have the flight and the games on Mondays and Thursdays. It was clear to us that we would not have time for proper training," he said.

"The team, coaching team and club want to win the next title, we all know that it is not easy.

"In addition to getting some vitamin D [sunshine], it is also a change from everyday life, even if the journey is dangerous.

"We want the sixth title in a year, the team would make history."

Flick had some words of encouragement for Niklas Sule, the defender who has only started two of Bayern's past six Bundesliga matches and was recently linked with a move to Chelsea.

"Niklas is an absolute option, whether in the centre or full-back position," he said of the Germany international, who suffered a ruptured anterior cruciate ligament last season.

"He did well at Schalke [last month's 4-0 win where Sule played at right-back]. Don't forget that he had a long injury.

"Niklas is a fast player who is serene on the ball and helps shape the game from behind. Given his size, he has absolute strength and I'm glad he's on our team.

"We will see how everything develops and how he sees his future. I am satisfied with his development, you can rely on him."

Preparations for the Australian Open were dealt a fresh blow on Wednesday when a member of hotel staff tested positive for coronavirus, although Victoria's premier insists the tournament is not under threat at this stage.

A 26-year-old worker at the Grand Hyatt Hotel returned a negative test at the end of his previous shift on January 29 but subsequently developed symptoms and tested positive on Wednesday.

As a result, Melbourne and the wider Victoria region has reverted to its New Year's Eve restrictions of gatherings at home being limited to 15 people and masks having to be worn in public indoor spaces.

In terms of the specific impact upon participants in the Australian Open, players, officials and support staff who were staying at the hotel during this period must now isolate and undertake a COVID-19 test.

The number of tournament-related personnel classed as "casual contacts" related to the incident is estimated to be between 500 and 600.

Nevertheless, Victorian premier Daniel Andrews told a news conference he was confident the Australian Open would go ahead as planned, even though the requirement that some players isolate and test could have an impact upon warm-up tournaments that are ongoing at Melbourne Park.

"There's about 500-600 people that are either players and officials and others who are casual contacts," Andrews said.

"They will be isolating until they get a negative test and that work will be done tomorrow so it might have an impact on tomorrow's play in the lead-up event, but at this stage there's no impact to the tournament proper.

"That's important to us, but the issue we're most focused on is much broader. That's about public health and public safety and that's why we've really pounced on this."

The Australian Open is scheduled to run from February 8-21.

Daniil Medvedev and Andrey Rublev produced ruthless performances as Russia cruised into the ATP Cup semi-finals.

Russia followed up their day-one win over Argentina with victory against Japan to ensure they will finish top of Group D.

Rublev got things rolling with an emphatic 6-1 6-3 win over Yoshihito Nishioka and Medvedev dispatched Kei Nishikori in a 6-2 6-4 triumph.

Those results meant the subsequent doubles match – which Japan won – would not be relevant.

"I am really happy for the team," said ATP Finals champion Medvedev, who has now won 12 matches in a row on the tour.

"Reaching the semi-finals is a big step – I am really happy that we made it in both singles. Both matches were straight sets, so really happy for the team and hopefully we can go further than that."

Italy, who had beaten Austria on the opening day, are also through after Fabio Fognini and Matteo Berrettini earned wins in straight sets over France duo Benoit Paire and Gael Monfils on Wednesday.

France play Austria next but neither team can catch Italy in Group C.

Alexander Zverev won a thriller against Denis Shapovalov 6-7 (5-7) 6-3 7-6 (7-4) to ensure Germany defeated Canada.

It was a first win at the ATP Cup for US Open runner up Zverev, who had a miserable tournament in 2020.

That sets up a day three contest for Germany against Novak Djokovic and Serbia where the winning team will progress to face Russia.

KYRGIOS AND WAWRINKA THROUGH

Nick Kyrgios – playing his first tournament for a year – made it two wins from two at the Murray River Open, defeating fellow Australian Harry Bourchier 6-2 7-6 (9-7).

First seed Stan Wawrinka survived a scare before prevailing against Mikhail Kukushkin to win 4-6 6-3 6-1 in just under two hours.

Wawrinka will take on Alex Bolt in the last 16, while Kyrgios should be tested against fourth seed Borna Coric.

At the Great Ocean Road Open, top seed David Goffin crashed out as world number 146 Carlos Alcaraz celebrated a shock 6-3 6-3 victory.

Karen Khachanov and Jannik Sinner were among the seeds who progressed, both winning without dropping a set.

Serena Williams roared into the quarter-finals of the Yarra Valley Classic with a 6-1 6-4 victory over Tsvetana Pironkova on a star-studded day of action in Australia.

The 23-time grand slam champion was in fine form at Melbourne Park, where the biggest names in women's tennis were competing across multiple tournaments, as she sealed a straight-sets triumph to continue her preparations for a shot at an eighth Australian Open title.

In doing so the 39-year-old extended her head-to-head record over the Bulgarian to 6-0 and was delighted to get the job done.

"It's definitely nice to get another win," the American said during her on-court interview.

"She's clearly a great player, so it wasn't easy, but it was good to come through."

Speaking at her media conference, Williams added: "Last time it was an incredible three-set match, so today I was like, 'All right, let's really try and focus and learn to do better than last time.'"

World number one Ash Barty had a less straightforward path to the last eight, requiring three sets to see off Marie Bouzkova.

The home hope ultimately prevailed 6-0 4-6 6-3, with second seed and reigning Australian Open champion Sofia Kenin also taken the distance in a 5-7 7-5 6-2 win over Jessica Pegula, as Nadia Podoroska dug deep to down Petra Kvitova 5-7 6-1 7-6 (9-7).

With Barty now set to face Shelby Rogers, Danielle Collins awaits Williams having impressively defeated third seed Karolina Pliskova 7-6 (7-5) 7-6 (7-3), while Garbine Muguruza overcame Anastasia Pavlyuchenkova 6-1 6-2 to set up a meeting with Kenin.

In the Gippsland Trophy, the top three seeds all dodged upsets, with two-time grand slam winner Simona Halep, 2019 Australian Open victor Naomi Osaka and 2018 Tour Finals champion Elina Svitolina safely navigating through the last 16.

Fifth-seeded Briton Johanna Konta failed to convert two match points as she succumbed to a 4-6 7-6 (12-10) 7-6 (7-4) defeat to Irina-Camelia Begu.

Meanwhile, at the Grampians Trophy there were wins for Anett Kontaveit, Jennifer Brady and Angelique Kerber.

Daniel De Silva scored the winner as Central Coast Mariners came from two goals down to beat 10-man Melbourne City 3-2 and go top of the A-League on Wednesday.

City took the lead when Adrian Luna steered Craig Noone's delivery home with an exquisite first touch and in the 31st minute Jamie Maclaren dinked a brilliant finish over Mark Birighitti to put the visitors in control at Central Coast Stadium.

The Mariners pulled one back before half-time, though, Jaden Casella tapping in his first A-League goal after being teed up by captain Matt Simon.

Simon was making his 200th A-League appearance for the Mariners and, after drawing a foul from Nathaniel Atkinson in the box, he drilled the resulting penalty into the bottom-left corner to restore parity.

The hosts' chances of staging an unlikely turnaround were boosted by Kerrin Stokes receiving a second yellow card in the 60th minute, and De Silva got the job done with a thumping finish 10 minutes from time.

The Mariners moved three points clear of Brisbane Roar at the summit, though they have played two games more. City, runners-up in last season's Grand Final, sit eighth after a third defeat of the season.

Joao Felix has tested positive for COVID-19, adding to Diego Simeone's problems ahead of Atletico Madrid's meeting with Celta Vigo.

Portugal international Joao Felix is self-isolating at home, as team-mates Mario Hermoso and Yannick Carrasco have been doing since Friday.

A brief Atletico statement read: "Joao Felix has tested positive for COVID-19. The striker is isolating at home, in compliance with the health authorities' guidelines and LaLiga protocols."

Simeone's men have a 10-point advantage at the top of LaLiga and welcome Celta to the Wanda Metropolitano on Monday. They then travel to Granada the following Saturday.

Hermoso and Carrasco are unlikely to return for the meeting with Celta, while Kieran Trippier will be absent due to suspension.

Joao Felix marked his return to the starting line-up against Valencia on January 24 by scoring his first goal in almost two months and setting up another, leading Atletico from a goal down to a 3-1 victory.

The 21-year-old has been left out of the first XI eight times in LaLiga this season and Atletico have won all those matches.

However, when Joao Felix starts they average two more shots (12.1 to 10.0) and their goals-per-game ratio improves from 1.9 to 2.3.
