Zinedine Zidane was in a defiant mood and vowed neither he nor his Real Madrid players will throw in the towel during a difficult period.

Los Blancos coach Zidane was absent for the team's past two LaLiga fixtures due to coronavirus, with Madrid following a victory over Deportivo Alaves with defeat against Levante.

The Levante loss was Madrid's fourth in LaLiga this season, one more than they suffered in the whole of their title-winning 2019-20 campaign.

Throw in a shock Copa del Rey defeat to Alcoyano and the pressure has been mounting on Zidane's position as head coach.

But a noticeably fired-up Zidane came out fighting when previewing Madrid's clash against Huesca.

"Well, I can't see into the future, I can't tell you what will happen. I think we need to be in this until the end," he said.

"There's a lot of talk that maybe a change is needed, maybe the manager, maybe this, maybe that, whatever needs to happen will happen. 

"I've said since day one I'm fortunate to be here, I'll make the most of my time here until my last day at the club. 

"If people want me to throw in the towel or the players to give up, I can say neither I nor the players are going to do that. 

"Of course a lot has been said about what we're going through right now, this spell, we haven't recently won enough games. But we're confident we can turn the tide.

"I think we all want to, we all need to, give our all until the end of the season. Of course, a lot could happen from now until the end of the campaign but as a team we're all rowing in the same direction. We're never going to give up, we'll give 100 per cent."

Madrid won 10 straight games and drew their final league fixture when LaLiga resumed after lockdown last season to win the title by five points.

This time around they are third and 10 adrift of leaders Atletico Madrid, with their city rivals owning a game in hand.

There have been suggestions Madrid need to freshen up an aging squad in the close season, but Zidane thinks his team deserved the opportunity to defend their title and more respect should be shown.

"I work, as you know, every day with the players, not at home, although I have been at home recently. Now I'm recovered and fully on board again," he added. 

"We're the defending league champions, we won the title last year. We had the right to try and defend the title we won last season. Maybe next season things will change, but I think we should have the chance to rightfully defend what we won last season. 

"We're not talking about what we won 10 years ago – it's about respect. It's a question I understand, I see comments of course. I think it's good you can say you don't want me here, or don't want me at the club but I think we just need a chance to defend what we won last season.

"I'm the number one in charge of this project. As for next year there'll be changes but I think we deserve this year, this squad deserves the chance to prove themselves to do this for the fans. 

"Nobody is going to jump ship, we'll all going to give it our all for the fans. Hopefully we can give them some things to celebrate, to shout about, they love their team, want to see the team win, play good football. We're going to try and do all those things.

"When we play badly or have a poor result, I think the press can sometimes criticise or be over the top. 

"I think we earnt that respect, and if we don't reach our goals come the end of the season, hand up I'll be the first to accept the blame. 

"Maybe I'm a bit angry, upset, I've been locked up indoors recovering from COVID. Now I'm back we'll battle until the end."

Novak Djokovic said it was "a tough one" to take after Serbia's hopes of retaining the ATP Cup title were ended by defeat to Germany.

The world number one scored a tense 6-7 (3-7) 6-2 7-5 victory over Alexander Zverev in their singles rubber, levelling the match after Jan-Lennard Struff beat Dusan Lajovic in three sets.

Zverev and Struff then teamed up in doubles to net a 7-6 (7-4) 5-7 10-7 win over Djokovic and Nikola Cacic.

The singles workout and win sets up the eight-time Australian Open champion well for the start of that grand slam next week, which was the consolation Djokovic could take from defeat.

Speaking about his singles clash with Zverev, Djokovic said: "It was anybody's game really. He was a set up, a couple points here and there in the beginning of the second. I just returned well when I needed to and closed out the match.

"It's never easy playing against Sascha [Zverev] when he's in form, and he's in really good form. We pushed each other to the very limit, and I'm glad that I had such a battle with him.

"It's unfortunate we lost the tie. That's what this competition is all about. It's about the team, not about winning one match, a singles match. Yeah, it's a tough one."

Germany advance to face Russia in the semi-finals on Saturday, with Daniil Medvedev and Andrey Rublev a formidable combination awaiting them.

Spain secured a shot at Italy in the second semi-final, despite a 2-1 defeat to Greece on Friday.

The Spanish team needed just one win in the group-stage match to advance, and that predictably came as Pablo Carreno Busta, ranked 16th by the ATP, beat world number 462 Michail Pervolarakis.

His 6-3 6-4 success could not be matched by team-mate Roberto Bautista Agut, who fell to a 7-5 7-5 defeat against Stefanos Tsitsipas, while Spain retired from the doubles rubber after one game, giving Greece a 2-1 success in the tie.

It remains to be seen whether Rafael Nadal will be fit to play any part in the semi-final, with the 20-time grand slam champion having been absent so far in the campaign due to a back injury.

"He's working very hard to recover his best feelings," said Spain captain Pepe Vendrell.

"Obviously he couldn't play any matches during the week. It's a situation that we have to study. But day by day he's improving. We will see [on Saturday] if he can play."

AWAY FROM THE ATP CUP, WAWRINKA ABANDONS

In the Murray River Open, Stan Wawrinka withdrew from his quarter-final with Jeremy Chardy after beating Australian Alex Bolt in a tough three-set match earlier in the day. Corentin Moutet, Dan Evans and Felix Auger-Aliassime joined Chardy in the last-four line-up.

Evans defeated Borna Coric, who had eliminated Australian hope Nick Kyrgios in his previous match.

All ATP and WTA tournaments are being played at Melbourne Park this week.

Thursday's play was cancelled due to a COVID-19 case affecting a worker from a hotel that accommodated quarantining players, and that meant Friday's schedule was packed.

The Great Ocean Road Open also saw players needing to win two matches in a day to reach the semi-finals, with Karen Khachanov, Thiago Monteiro and the Italian pair of Jannik Sinner and Stefano Travaglia coming through.

Joe Root savoured a "very special" opening day of the series against India as the in-form England captain marked his 100th Test with a sublime unbeaten century in Chennai.

Root has made a dream start to 2021, scoring a double century in the first Test against Sri Lanka and crafting a hundred in the second match as the tourists sealed a 2-0 whitewash in Galle last month.

The England skipper continued his purple patch at M. A. Chidambaram Stadium on Friday, becoming only the ninth player to reach three figures in his 100th Test.

Root was unbeaten on 128 at stumps and although Dom Sibley was dismissed in the final over of the day to end a stand of 200, England are in a strong position on 263-3.

The skipper was understandably emotional on a landmark day and was grateful for some kind words from his team-mates, particularly his deputy Ben Stokes.

He said: "It's very special. Last night the guys put a little surprise together for me – some videos from some past players, and friends and family. And Ben, in particular, stood up and said some really kind words.

"What he said should stay between the two of us and the group, but Ben's a fine human being and it was really nice of him to go out of his way to say some very special things that I will hold dear forever."

"The guys have made it very special for me and I really appreciate it. It's been an amazing two days. I was a little bit emotional [at the toss]," Root added. "I couldn't even remember our team when they asked me about it.

"I was a little bit all over the place, but thankfully when I got out there, I knew it was business as normal and I had a job to do.

"For us to start this series in the way that we have, it couldn't have gone any better, bar a little blip at the end there. So, I really hope that we can build on that tomorrow and I'm obviously delighted with how things have gone personally."

Root stressed the importance of England capitalising on such a promising start.

"We've got to look to try and get as many as we can – 600, 700 if we can, really try and make the most of the first innings while it's good," he said.

"Those foot holes are starting to wear quite quickly. So, if we can bat the whole of tomorrow and maybe into day three, then things could speed up quite quickly for us and you never know what can happen from that point onwards."

Root was full of praise for opener Sibley, who faced 286 balls in a great knock and looked untroubled until he was trapped leg before by Jasprit Bumrah (2-40)

The Yorkshireman said: "That was a fantastic innings today. To come out with maybe a few question marks in his own mind about his game against spin, for him to go and put a performance early on in this series like that, against a high quality attack delivering reverse swing as well, was really impressive.

"He should take a lot of heart and confidence from that into the rest of the series. I really did feel for him – he deserved a hundred – but that's what happens when you play against good players.

"They can take wickets later on in the day and the challenge will be to try and better that partnership that we got together, try and better that tomorrow."

Pep Guardiola expressed disappointment with Jurgen Klopp's attempt at pre-match mind games after the Liverpool manager falsely claimed Manchester City had "a two-week break for COVID reasons".

Champions Liverpool host Premier League leaders City on Sunday, where Guardiola's men have the chance to go 10 points clear of Klopp's side with a game in hand if they can claim a first win at Anfield since 2003.

Both men addressed the media on Friday, with Klopp speaking first and suggesting a coronavirus outbreak within the City squad between Christmas and new year actually helped their title bid.

Asked about Guardiola's recently repeated mantra that his team - currently on a 20-match unbeaten run across all competitions - are playing better because they have managed to "run less" in possession, Klopp focused his attention upon the spike in infections that saw City's scheduled December 28 trip to Everton postponed.

"The more you keep the ball, the less you have to run, probably. We didn't have a break," he said.

"I think City had a two-week break for COVID reasons. It's really tough. It's a tough year, season; for some teams, it looks like lesser but, for us, for the reasons you know, it's tough."

In reality, City had a seven-day break between their 2-0 win over Newcastle United on Boxing Day and a January 3 trip to Chelsea, where a squad heavily depleted by a raft of players being forced to self-isolate secured an impressive 3-1 win.

Having started his own briefing later than scheduled, Guardiola opted to respond initially with heavy sarcasm.

"He made a mistake, it was two months off or three months off. Four months we had off. That is why we are in top form right now," he said.

"Jurgen has to see the calendar again. We had COVID, we had one week and we played with 14 players at Stamford Bridge, Maybe I'm wrong, maybe it was three or four weeks.

"Tomorrow when I see Jurgen I'll say to him, 'How many weeks or days were we off?'"

Guardiola famously endured a tempestuous back and fourth with Jose Mourinho when the pair were in charge of Barcelona and Real Madrid a decade ago - an affair he was perhaps referencing when stating he held Klopp, whom he also competed against in the Bundesliga, to higher standards.

"I'm surprised," he said. "I thought Jurgen was not that type of manager like other ones [for whom] it is usual to do it. I didn't expect that comment. From him, I didn't expect it.

"He knows it’s not true, come on! Nobody in the Premier League has had two weeks off, everyone knows. In some situation you do it [mind games] for a purpose, but I did not expect he will do it."

Liverpool have lost their past two home games 1-0 to Burnley and Brighton and Hove Albion.

Nevertheless, Anfield remains something of a final frontier for Guardiola as City boss, having lost four and drawn one of his five visits to the red side of Stanley Park.

"They are always an incredibly tough team and remain a tough squad," he said.

"They know the process, the skills, the routines and methodology they do offensively. No change.

"They are aggressive and will be more aggressive than ever, I'm pretty sure. They'll rest really well after the game against Brighton and they'll recover in these two weeks off and they will be ready."

City remain without Kevin De Bruyne (hamstring), Nathan Ake (muscular) and Sergio Aguero, who has endured a prolonged absence after testing positive for coronavirus. He is expected to return in a few weeks.

South Africa face a battle to avoid another first-innings deficit after Anrich Nortje's fine work with the ball was undone by a rocky reply to Pakistan's 272 in the second Test.

Pakistan had made 145-3 on day one before rain intervened and Nortje was the cause of their frustration when play resumed on Friday, snaring 5-56 to put the hosts in the field before tea.

But the Proteas' solid early efforts with the bat - including a string of boundaries - were disrupted by Hasan Ali, who removed Dean Elgar (15) and Rassie van der Dussen from consecutive deliveries.

With those wickets right at the end of the second session, the day turned and Faf du Plessis followed to Faheem Ashraf for 17.

Nauman Ali - sublime in the first Test as Pakistan dominated - then teed up a simple but crucial catch for Shaheed Afridi to remove Aiden Markram (32), reducing South Africa to 81-4 before a mini-recovery to 106 without further loss preceded the close of play.

It ended a day of two halves as the Proteas, just like a day earlier, enjoyed a productive first session, with Babar Azam unable to add to his overnight score of 77, edging Nortje to second slip from just the second ball of the day.

Fawad Alam (45), who had held up the other end of a vital partnership on Thursday, swiftly followed, too, run out with a superb direct hit from Temba Bavuma.

Faheem steadied the Pakistan innings slightly, although Nortje's decision to take the second new ball soon paid dividends as he halted Mohammad Rizwan (18) in his next over.

That dismissal ended a promising stand of 41 and Faheem eventually ran out of partners, still unbeaten on 78 as Nortje concluded the innings and his five-for with fierce deliveries to Nauman and Shaheen in the same over.

Only if South Africa can regain some composure with the bat will Nortje be able to celebrate his contribution to a much-needed win, which would be their first in 14 Tests on the subcontinent.

HASAN ALI HAVING HIS SAY

Hasan has endured a tough time with injury in the past few years, returning to the Test arena in this series for the first time since January 2019. If the fast bowler was merely playing a supporting role to the spinners in the opening match last week, this was a more telling contribution, potentially changing the course of the result.

SOUTH AFRICA TURN TO SKIPPER

Quinton de Kock would appear to be taking charge of his final Test match as South Africa captain but may now have to rediscover his best form to make sure it is not a losing swan song. The skipper has not made a Test fifty since January 2020 or a hundred since October 2019, yet the Proteas were reeling as he arrived at the crease on Friday, able to settle the innings a little by dashing to an unbeaten 24 at stumps.

Barcelona were handed a tough draw against Sevilla in the Copa del Rey semi-finals as Ronald Koeman chases his first trophy since being appointed head coach.

The two-leg tie will be a repeat of the teams' memorable meeting at the quarter-final stage two years ago, when Sevilla won 2-0 at home before being thrashed 6-1 at Camp Nou.

Koeman, who took charge last August, saw his side beaten 3-2 in the Supercopa de Espana final by Athletic Bilbao in January, when Lionel Messi was sent off in extra time.

That silverware slipped by but the Dutch coach will hope for a better outcome for Barcelona as the Copa del Rey enters its final stages.

They were almost knocked out in the quarter-finals this week by Granada, saved by late goals in normal time from Antoine Griezmann and Jordi Alba before winning 5-3 after extra time.

Facing Sevilla will surely be no easy task given Barca, second in LaLiga, are just a point ahead of Julen Lopetegui's team.

There could be another final between Barcelona and Athletic in store, with the Bilbao giants drawn to face Levante in the other semi-final.

The first legs of each tie will be played next midweek, with the return games to be played on the first midweek in March, with exact dates for each match to be determined.

Sevilla will have extra incentive to reach the final, given that match will be staged in their home city on April 17, at Estadio La Cartuja.

Because of the coronavirus impact on Spanish football, last season's Copa del Rey final has yet to be played, with that game between Athletic and Real Sociedad to be played at the same Seville stadium on April 3.

Barcelona hold the record for the most Copa del Rey titles, having won the competition 30 times, with Athletic next on the list with 23 victories.

Jose Mourinho has little interest in external scrutiny after three consecutive Tottenham defeats, insisting he places enough pressure on himself.

Spurs host struggling West Brom on Sunday but head into the weekend eighth in the Premier League, 14 points off top, after losing to Liverpool, Brighton and Hove Albion and Chelsea consecutively.

That miserable run has made Mourinho the first Tottenham boss since Andre Villas-Boas in November 2012 to suffer three defeats in a row in the league.

Indeed, the reverses against Liverpool and Chelsea represented the first time in 327 home league matches in Mourinho's managerial career he has lost back-to-back games.

Speaking ahead of the West Brom game, where Spurs will aim to bounce back at Tottenham Hotspur Stadium, Mourinho offered a spiky response when asked about increasing pressure, referring to the club's wait for a league title that stretches back to 1961 and a total trophy drought of more than 12 years.

"I put pressure on myself every day," he said. "I don't need others to put pressure on me, I put pressure on myself every day.

"Since 2012 without three defeats in a row, correct? How long since a title? Maybe I can give one."

Mourinho added his focus remains on the short term and again getting the better of Sam Allardyce, the West Brom boss against whom he has never lost in 12 Premier League meetings.

Even with West Brom 10 points shy of safety after losing to bottom side Sheffield United, Mourinho is aware of the threat they pose.

The Baggies have held Manchester City and Liverpool away from home this term and beat Mourinho's Manchester United at Old Trafford during their previous relegation campaign in 2017-18.

"The most important thing now is West Brom," Mourinho said. "I don't even want to think about [subsequent fixtures against] Everton or City.

"After City, we go to Austria in the Europa League, which is a big competition for us that we have good expectations in.

"But I don't even want to think about that, I want to think about West Brom. That's a big game. Sometimes big games are just against the top six or the London derbies or whatever it is, other times big games are games like this.

"It's a big game for West Brom because they need a victory, they need points to survive, to get out of where they are.

"It's a big game for us because we need to leave the position where we are, which is not a dramatic position like theirs but is a very bad position for us, so we need to leave it.

"We need to break the dynamic of three defeats like you saw, so it's a very important match for us.

"But the reality is until the end of the month we have great motivations in front of us. The Europa League is something that since the beginning we put a lot on.

"I cannot forget that we had to play many games to qualify for the group stage, games with two days in between, travelling around Europe to play.

"The team wants and the team is waiting for that, maybe the squad needs that, but let's focus on West Brom because it is the next match and, after three defeats, we have to win against West Brom; we cannot even think a different thing."

An own goal from substitute George Timotheou gave Perth Glory a 2-1 comeback win over Adelaide United in the A-League.

United captain Stefan Mauk put the hosts ahead in the 20th minute, timing his run into the box perfectly to convert Ben Halloran's cutback.

The advantage remained until the 73rd minute, when Bruno Fornaroli converted from Neil Kilkenny's pass to crown a patient team move.

Ten minutes later, Perth grabbed the goal that moves them up to third in the standings - leapfrogging teams including Adelaide, who drop to sixth.

United failed to deal with a short corner and the ball broke to Daniel Stynes, whose drive took a decisive deflection off the unfortunate Timotheou.

Joe Root once again led from the front for England, marking his 100th Test match with another glorious hundred against India in Chennai.

Visiting captain Root came to the crease before lunch on day one of the first Test after the tourists lost Rory Burns and Dan Lawrence, the latter for nought, with the score on 63.

Alongside opener Dom Sibley, who was trapped lbw for a typically robust 87 by Jasprit Bumrah from the final ball of the day, Root came through a stern examination before making hay as the India attack tired.

It was another sparkling display from the 30-year-old right-hander, whose 128 not out followed scores of 228 and 186 during last month's 2-0 win in Sri Lanka and left England 263-3 at stumps.

Rory Burns was back at the top of the England order having sat out the previous tour due to the birth of his first child and the Surrey left-hander looked in fine touch after Root won the toss, delightfully clipping Ravichandran Ashwin through midwicket after he and Sibley brought up the fifty partnership.

But Ashwin (1-68) had his revenge in an awful moment for Burns, who misjudged a reverse sweep to loop a simple catch to wicketkeeper Rishabh Pant and depart for 33.

Lawrence was promoted up the order after Zak Crawley was ruled out with a sprained wrist, and India skipper Virat Kohli decided to see how he might fare against quality pace bowling. He soon had an answer as Bumrah (2-40) found reverse swing to pin the Essex man in front.

Root survived a strong lbw appeal from Ishant Sharma and he and Sibley were forced to dig in against some high standard bowling either side of lunch.

Again displaying impeccable balance and judgement, Root initially put away the sweep shot that served him so well in Sri Lanka and was watchful against Ashwin and slow left-armer Shahbaz Nadeem on a surface displaying more bounce than expected.

He started to move through the repertoire when all-rounder Washington Sundar entered the attack. The partnership was 77 when England reached tea at 140-2, with Sibley through to a half-century.

They motored on in the evening session, with Root reaching three figures with a trademark tuck behind square into the leg side before shedding his earlier inhibitions and bludgeoning Ashwin for a slog-swept six. He must continue on Saturday without Sibley, whose 286-ball vigil came to a cruel end.

Ajax goalkeeper Andre Onana has been suspended for 12 months by UEFA due to a doping violation, the Eredivisie club have confirmed.

Ajax and Onana will appeal to the Court of Arbitration for Sport (CAS) to overturn the ban, imposed after an out-of-competition test in October 2020 found the substance Furosemide in the player's urine.

The club said the test result was due to Onana, 24, mistakenly taking Lasimac – a drug prescribed to his wife – when he felt unwell.

UEFA therefore accepted Onana "had no intention of cheating", an Ajax statement read.

It added: "However, UEFA believes, on the basis of the applicable anti-doping rules, that an athlete has a duty at all times to ensure that no banned substances enter the body."

The suspension is effective from Friday and applies to "all football activities, both national and international".

Ajax managing director Edwin van der Sar said: "We explicitly renounce performance-enhancing drugs, we obviously stand for a clean sport.

"This is a terrible setback, for Andre himself but certainly also for us as a club. Andre is a top goalkeeper, who has proven his worth for Ajax for years and is very popular with the fans.

"We had hoped for a conditional suspension or for a suspension much shorter than these 12 months, because it was arguably not intended to strengthen his body and thus improve his performance."

Cameroon international Onana has been a key man for Ajax since his debut in 2016-17, playing his part in runs to the Europa League final and Champions League semi-finals.

His absence is the latest blow to Ajax, who earlier confirmed they would be unable to correct the administrative error that saw Sebastian Haller left out of their Europa League squad.

Haller, signed from West Ham for a club-record €22.5million last month, was not included in Ajax's initial list for European competition for the second half of the season.

Coach Erik ten Haag described the mistake as "an administrative error with major consequences" and "an incredible setback" for the player, although he confirmed Ajax would be addressing the matter with UEFA.

However, a further club statement has now confirmed UEFA sent "a final message" to say Haller could not be added to the group.

Haller has scored two goals in his first seven games for Ajax in all competitions.

England captain Joe Root has become the ninth player in history to score a century in his 100th Test match.

The 30-year-old made his milestone appearance on day one of the first Test against India in Chennai on Friday.

During a terrific third-wicket stand with Dom Sibley, Root marked a memorable day with the 20th Test ton of his international career off just 164 balls.

Only eight players have previously celebrated a century of Test caps by scoring 100 runs, the last being Hashim Amla, who scored 134 for South Africa against Sri Lanka in January 2017.

The highest such score for a centurion is 149, set by Gordon Greenidge for the West Indies against England back in April 1990.

Root is just the third Englishman on the list, following Colin Cowdrey in 1968 and Alec Stewart in 2000.

England lost Rory Burns for 33 and Dan Lawrence for a duck before Root and Sibley began to nullify the India attack.

England were 227-2 as Root celebrated a third century in as many Tests, with Sibley on 83 from 250 deliveries.

Serena Williams has withdrawn from her semi-final at the Yarra Valley Classic due to an injury to her right shoulder.

As a result, home favourite Ash Barty will progress to the final of the Australian Open warm-up event at Melbourne Park.

Williams, who is chasing an eighth Australian Open crown and an historic 24th grand slam singles success, had been in impressive form this week, demolishing Tsvetana Pironkova in straight sets.

Friday's quarter-final against American Danielle Collins proved a harder slog, as she was forced into a match tiebreak to win 6-2 4-6 10-6.

An anticipated showdown against Barty will now not come to pass, with the world number one to pursue a ninth career title against either Garbine Muguruza or Marketa Vondrousova.

"I think the rust is always there for everyone the first few matches of the season. But without a doubt, I felt better and better each match," Barty told reporters after being taken the distance by Shelby Rodgers.

"Each match has been very different, different challenges, different things I've had to overcome, which is the best thing, to be able to work through those and give myself another chance to play a little bit better the next day, focus on some new challenges for the next day."

Williams is due to face Germany's Laura Siegemund in the first round of the Australian Open on Monday.
