Luka Doncic banked 40 points for the Dallas Mavericks but still felt he was to blame for Wednesday's 120-114 overtime defeat to the Oklahoma City Thunder.

The two-time NBA All-Star impressed with a further 10 assists, five rebounds and three steals, yet it was not enough to prevent the Mavericks from falling to back-to-back defeats.

The Thunder scored a quick lay-up with eight seconds remaining of regulation time to tie the contest, with Doncic missing on a 28-foot 3-pointer at the buzzer.

Despite registering his second-highest score of the season, one short of the 41 managed against the Toronto Raptors last month, Doncic was not pleased with his overall display.

"That was just my bad. I didn't see it coming," said Doncic of his defense on the Thunder's final shot in regulation. 

"This game is on me… the last two possessions shouldn't happen. By far, my worst defensive game this year for sure, and it's just on me."

It is the first time since Christmas that the Mavericks have lost successive games and leaves them fifth in the Western Conference, now 29-23 for the season.

Lu Dort was the hero for Oklahoma, scoring 14 straight points in overtime and 30 in total – his second 30-point game of the season, compared to one in the previous two years.

"In the biggest part of the game, he had his foot on the gas and closed it out for us," said Thunder coach Mark Daigneault.

The Mavericks had won their previous eight home games, but head coach Jason Kidd had no complaints about the defeat.

"They just played harder than we did," Kidd said. "When it got tight there, we started to play better. 

"We put ourselves in a position like Orlando: Someone had to make a shot – someone did. We just couldn't get the stop on the other end."

Frank Vogel hailed the "mental toughness" of Anthony Davis and his Los Angeles Lakers side after snapping a three-game losing run with a 99-94 win over the Portland Trail Blazers.

Davis stepped up in the absence of LeBron James – missing a fourth straight game with knee soreness – with a double-double of 30 points and 15 rebounds in Wednesday's contest.

The eight-time NBA All-Star has now had at least 30 points and 15 rebounds in three games this season and has averaged 29.3 points over his last three outings.

Davis's latest haul helped the Lakers improve to 25-27 in the Western Conference, and head coach Vogel was particularly pleased with the spirit he saw from the 28-year-old.

"He had some great sequences of grabbing rebounds in traffic," Vogel said.

"Tonight was about mental toughness and making enough plays and shots. It was a hell of a game by Anthony."

Nineteen of Davis's 30 points arrived in the final 12 minutes, with seven of his 15 rebounds coming in the fourth quarter

"I just tried to come out with the mindset of ending the streak," Davis said. "We have to play with some urgency. We just fought hard tonight. It was a great game for us."

Carmelo Anthony added 24 for the Lakers, who had lost to the Philadelphia 76ers, the Charlotte Hornets and the Atlanta Hawks in their previous three games.

Despite the best efforts of 30-point Norman Powell, Portland have now lost three in a row and five of their last six in a run that has seen them slip to 10th in the Western Conference.

"We had a couple breakdowns today," Powell said. "We had some good stops but gave them second and third-chance opportunities."

The Lakers are back in action against the Los Angeles Clippers on Thursday, while Portland face the Oklahoma City Thunder on Friday.

Kyrie Irving is growing tired of the Brooklyn Nets using "get-better jargon" after the team suffered a sixth straight NBA defeat in a 112-101 loss to the Sacramento Kings.

The Nets have slumped to sixth in the Eastern Conference standings and are now on their worst streak since a seven-game losing run between December 2019 and January 2020.

Nic Claxton had a career-high 23 points to go alongside 11 rebounds, while James Johnson put up 18 points. Irving had 14, but it was a tough night for the usually prolific James Harden, who had just four on the back of two-of-11 shooting.

Irving feels there have been "morale victories" during the Nets' barren run but he has little interest in anything other than actual wins.

"When you're going through a losing streak, not many people want to hear the same thing over and over again," he said.

"The get-better jargon that we consistently use, it can get mundane. 

"Game to game we're feeling like we're coming out with some morale victories if we lose, but I'm tired of that."

Harden has been contending with an issue to his right hand and a hamstring complaint, with his return his lowest since playing the Chicago Bulls on May 15 last year.

Despite the Nets' woes, Harden is confident the team can soon turn the corner, especially if they can get some key personnel back after the All-Star break.

"There's no concern," Harden said. 

"We don't have our entire team and this is happening to us. We're just trying to figure out what works best, what guys fit, what guys don't. 

"Hopefully after the break we can get our whole roster and start making strides in the right direction."

The Nets have had issues with their roster. Kevin Durant (knee) remains absent, while Joe Harris and Marcus Aldridge (both ankle) are still out, and Irving's involvement is restricted to road games as he is ineligible to play fixtures in New York as he is unvaccinated against COVID-19.

Head coach Steve Nash says the main objective right now is merely to show improvement on the court.

"This trip our objective is to get better. The first two games and the first half tonight we were getting better," Nash said. 

"We didn't contain the ball enough in the second half and we didn't make plays."

The Nets will aim to return to winning ways in Friday's trip to the Utah Jazz.

Superstars of the winter sports world are lining up at Beijing 2022 to create more breathtaking Olympic memories.

This festival of fast-paced action and technical excellence, a bewilderingly brilliant show set on snow and ice, has delivered sporting legends since it was first staged 98 years ago.

The Winter Olympics has ballooned in scale since Chamonix 1924, but its foundations were set then, with bobsleigh, curling, ice hockey, skiing in its varying forms and both figure skating and speed skating on the original programme.

Here, Stats Perform looks at the achievements of the greatest athletes to strike gold.

BIATHLON: Ole Einar Bjorndalen

Stemming from the sport known in 1924 as military patrol, biathlon is that peculiar blend of cross-country skiing and rifle shooting. It might be archaic in origin, but so too is the 100 metres dash at the summer Olympics, and biathlon remains an integral part of the winter programme.

Norwegian master Bjorndalen has been its greatest exponent, winning five solo gold medals and three in relay events. He competed at each Games from Lillehammer 1994 through to Sochi 2014, first striking gold at Nagano 1998. Bjorndalen peaked at Salt Lake City in 2002, landing four golds.

His fame has never rivalled that of a Michael Phelps or Usain Bolt, even though biathlon commands huge television audiences in parts of mainland Europe. Yet the man whose hunger for devouring the competition earned him the nickname of 'The Cannibal' belongs in Olympic legend.

Four silvers and a bronze took him to 13 Olympic medals in all, the most successful male Winter Olympics athlete for the most successful nation in the history of the Games.

CROSS-COUNTRY SKIING: Marit Bjorgen and Bjorn Daehlie

Bjorgen is the most successful athlete in Winter Olympics history, with eight gold medals, four silver and three bronze, out-ranking even Bjorndalen in Norway's parade of great champions.

She scooped 18 World Championship golds too, had 114 wins among 184 top-three finishes at World Cup events, and ranks as the third most successful Olympian of all time in terms of medals won, after swimming great Phelps (28 medals, including 23 golds) and Soviet gymnast Larisa Latynina (18 medals, nine golds).

Bjorgen made her Olympic debut in 2002 but had to wait until 2010 before landing a first gold at the Games, triumphing in the pursuit, the sprint and the 4×5km relay. Three more triumphs followed in Sochi, before Bjorgen, by now a mother, won twice again at Pyeongchang in 2018. Her career climaxed in a dazzling triumph by almost two minutes in the 30km race on the final day of competition, the gold vaulting Bjorgen above Bjorndalen on the all-time list in the process. She retired a matter of weeks later, a mission accomplished.

Oslo-based Bjorgen ranks only just ahead of compatriot and fellow cross-country superstar Daehlie in the grand totting up. Daehlie was the first Winter Olympics star to land eight gold medals, winning those from 1992 to 1998, including two in front of home crowds at Lillehammer in 1994.

He captured four silver medals across his Olympic career, too, and might have gone on to enjoy success in subsequent Games, only for injuries from a roller-skiing accident to force him into retirement in 2001, at the age of 33.

SPEED SKATING: Eric Heiden, Clas Thunberg and Viktor Ahn

Heiden's story is remarkable, with the American sweeping the board by winning five gold medals at his home Winter Olympics in 1980, taking the Games in Lake Placid by storm and instantly making himself an all-timer in speed skating. He snatched Olympic records across the board, and his feat would be remarkable enough if the story ended there, as the only winter athlete in history to win five gold medals in a Games, but Heiden had more up his sleeve.

He turned his focus to cycling and represented the United States on the track before switching to the road, winning a US national championship and competing at the 1985 Giro d'Italia and 1986 Tour de France, crashing out of the latter late on in the race. Later he became an orthopaedic surgeon, and to this day operates a medical centre in Park City, Utah.

Finland's Clas Thunberg also won five Olympic golds in speed skating, three at the inaugural Chamonix Games and two at St Moritz in 1928, before he went on to serve as a politician. Claudia Pechstein of Germany and Ireen Wust of the Netherlands have also both won five golds.

The only speed skaters to win more have been Lidiya Skoblikova, a six-time gold medallist for the Soviet Union in the 1960s, and Viktor Ahn, a more modern marvel.

Ahn, a short-track speed skater, won the first three medals of his set competing for South Korea as Ahn Hyun-soo in 2006 at Turin. He added three more after switching to race for Russia at the 2014 Sochi Games, a tough pill for Seoul to swallow, with Ahn having cited a lack of support from South Korean authorities as the reason for his sporting defection. South Korean president Park Geun-hye demanded answers.

Ahn was controversially not invited to compete for the Olympic Athletes from Russia team at the 2018 Games in Pyeongchang, South Korea. A state-sponsored doping scandal from Sochi saw the Russian Olympic Committee banned, with a makeshift team entering in their place. Ahn, who insists he has never cheated, said it was "outrageous" to exclude him.

FIGURE SKATING: Sonja Henie

Before she became a Hollywood movie star, and before Adolf Hitler became an admirer of her graceful routines, Norwegian Henie made her Winter Olympics debut as an 11-year-old in 1924. She was a raw talent at the time but in 1928 she landed the gold medal at St Moritz, before repeating the feat four years later at Lake Placid and completing a hat-trick in Garmisch-Partenkirchen in 1936. She had a fan in Hitler and warmly greeted the Nazi leader before the 1936 Games, which did not sit well with many, although she managed to set the controversy aside. Henie elected to turn professional after that triumph in Germany, ensuring she could monetise her talent, and American film studios soon beckoned.

Henie became an ever bigger star, appearing in a host of major box-office movies. Her Olympic gold medal success has never been beaten in figure skating, although Sweden's Gillis Grafstrom also won three consecutive titles in the men's event, with the first of those coming at the 1920 Summer Games in Antwerp, where figure skating was part of the programme.

ALPINE SKIING: Kjetil Andre Aamodt and Janica Kostelic

Alberto Tomba, Pirmin Zurbriggen and Marc Girardelli were bona fide superstars of the slopes in the 1980s and early 1990s, but none of them have an Olympic record to match that of Aamodt.

At the age of 20, Aamodt denied Girardelli the super-G gold at Val d'Isere in Albertville's 1992 Games, pulling off a shock victory that was an omen of things to come, although it was 10 years before he won a second Olympic gold. In Salt Lake City, Aamodt captured the super-G and combined titles, while four years later in Turin he edged out Hermann Maier to take a third super-G title, becoming the first male alpine skier to win four Olympic golds. That he did that after two injury-blighted years, at the age of 34, only enhanced the achievement.

Within minutes of Norwegian Aamodt reaching four, so too did Croatia's Janica Kostelic, the only woman to achieve such a haul. She had won three times in Salt Lake City in 2002, taking the slalom, giant slalom and combined titles, and in Turin, after a bout of sickness disrupted her preparation, Kostelic defended the combined.

Aamodt has eight Olympic medals in all (four gold, two silver, two bronze), while Kostelic has six (four gold, two silver).

George North is looking forward to the day his children face the big choice: cycling or rugby.

North is also looking forward to the Six Nations Championship, starting this weekend, when Wales begin their title defence against Ireland in Dublin.

There is an awful lot for this 29-year-old to be looking forward to, now that his injury hell has passed.

For now, North is enjoying the freedom of being able to run again, after suffering an anterior crucial ligament (ACL) injury in his right knee last April, playing for the Ospreys.

It ended his year on the rugby pitch, ruining hopes of a starring role for the British and Irish Lions in South Africa and denying him a shot at the Springboks, Australia and New Zealand in the autumn internationals.

North would sooner have been healthy and active of course, but being sidelined has had its upsides. He and his wife, double Olympic cyclist silver medallist Becky James, welcomed their second son, Tomi, a brother for Jac, in October.

Rather than dividing his time between the family and Wales camps, North has been essentially a stay-at-home dad for months on end.

"It's been brilliant. Normally I'm away playing or touring or something," says North, who is a Land Rover ambassador.

"To have this time at home, it's priceless. But Becky's been a superstar. When I had my surgery to start with, I couldn't do much on crutches with Jac, and obviously Tomi's joined us now and he's class.

"I'm in that stage now where effectively I'm in pre-season again, and I'm absolutely battered when I come home from training. And I'm not much use to anyone, but she's been amazing through this whole process.

"It has been tough, but it's been amazing you know, the two boys are amazing. Thank goodness for Becky, because it'd have been a lot harder at one point, with one leg up and hopping around the place. Especially my surgery, it was very tough. But yeah, she's a superhero."

Wales have been Six Nations champions four times in the last 10 years. Despite being holders, however, few are giving them much of a chance this time around.

After all, Wales have been up and down with results in the tournament. Across the last five years, they have trailed in fifth twice, as well as clinching a couple of championships, including the 2019 grand slam.

This time, they head into the tournament without a clutch of key players: North is absent, but so too is captain Alun Wyn Jones, with Taulupe Faletau, Leigh Halfpenny, Josh Navidi, Ken Owens and Justin Tipuric also sidelined.

Head coach Wayne Pivac said his squad has lost around 680 caps' worth of experience, but Wales should still be no mugs.

The players Pivac has chosen for the tournament come with an average of 27.1 Test caps of experience, only topped by Ireland's 30.9 among the six teams.

Those that are missing are proven class, however. In last year's championship, Faletau had 66 carries, putting him in third place among all players, while Tipuric made the most tackles (82). Faletau was fourth on that list (74), and skipper Jones was sixth (72).

On the Six Nations all-time list, North, who has featured on the wing and at outside centre, ranks fourth for metres gained (2,548), third for defenders beaten (126), and third for most clean breaks (48).

Jones is top of the all-time tackles chart (719), with fly-half Dan  Biggar a different animal to the absent lock. Biggar sits second on the Six Nations' all-time try assists list, after setting up 17 five-pointers in the competition.

To lose a raft of proven top-level talent would hurt any team, and North is not blind to that. He has been in and around the Wales squad since his late teens, however, so is certain there will be no defeatist attitude in Pivac's camp.

"Obviously there are a number of players out missing, and I think Wayne's come out with a stat of something like 680 caps that he's lost," says North. "That's a tough place to be."

But can Wales kick on regardless? North says so.

"Well, that that's the only way you get better, isn't it? By pushing the standards up every time," North tells Stats Perform News.

"I think for us, as Wales, we're used to being the underdogs, and we're always used to being kind of like always wanting more, and I think that shows in the performances that we have and the results we have had of late.

"From the lads' point of view, that's something they will certainly be looking at: how they push on from last year. Obviously winning the championship [is one thing], but you know the next step is backing it up again and as we said, it's going to be incredibly tough for the boys."

In the 2021 Six Nations, Wales made the most tackles of all teams (871), were third for tackle success with a healthy 88.2 per cent record, ranked second for lineout success with 90.8 per cent, and matched France for the most scrum success with 96.2 per cent.

Pivac's side averaged 3.7 points per entry into the opposition 22, making them the only side to average over three points per entry. It is a hard act to follow.

The loss of veteran skipper Jones gives 32-year-old playmaker Biggar the opportunity to lead the team into the championship.

"Yeah, it's not easy following the most capped player in the world is it!" North says. "I wouldn't like to follow Alun Wyn, put it that way.

"But what you're getting with Dan is a fierce competitor who drives the squad from the front row, right the way back all the way through to the full-back.

"He expects high standards of everyone, and he expects those standards of himself. I'm excited to see Dan as captain because what you see on the field is a fierce competitor. And that's not just on the field, that's Monday to Friday, and that's in whatever jersey he is.

"He expects the best for himself, and also the best from others because you know he is a competitor and wants to win."

North has the most international tries of all current players in the world game, and he has spoken of hoping to be available to Pivac at the back end of the championship.  Wales have home games against France and Italy on March 11 and 19 to finish the campaign.

He longs to make his children proud, even though both are much too young to understand his day job, or to understand their mother was a world champion.

From the routines of parenthood to the cauldron of the Principality Stadium, North is focused on pulling out all the stops. Jac and Tomi are keeping him grounded but also fuelling his ambitions.

"Obviously they don't know what Dad does. They don't know what Mum used to do," he says. "And I think that's something that's special.

"I am looking forward to the day that I'd be able to play and Becky can bring the boys to watch. I'm incredibly proud and honoured to be able to play rugby, but to be able to share that with the boys and, you know, show them more. Whatever they want to do in the future, there's always that conversation, is it a bike or a rugby ball?"

North, who during last year's Six Nations became the youngest player to reach 100 caps for any country, is targeting the 2023 Rugby World Cup as a long-range goal.

That could add up to over two months away from home, and given he will be 31 by the time that tournament comes around, it might be a last shot at global glory.

"I've got a fair few steps to cross off before we get back in any jersey. Certainly it's something I want to be able to put my hand up and be fighting for my selection there," he says.

"I've been very fortunate to go to a few now, and you know that's a big push. It's not too far away, and it's something that is certainly exciting."

There he goes again, always looking forward.

Anthony Davis stepped up with a double-double in LeBron James' absence as the Los Angeles Lakers ended their three-game skid with a 99-94 win over the Portland Trail Blazers.

James was absent for the fourth straight game with a knee issue but Davis took charge with 30 points, 15 rebounds and three blocks.

Russell Westbrook contributed with a double-double with nine points, 10 rebounds and 13 assists, while Carmelo Anthony added 24 points for the Lakers. Norman Powell landed five three-pointers in his 30-point haul for Portland.

The Lakers had raced to a 12-point quarter-time lead but the Blazers narrowed that to one point by half-time before seesawing second half which went down to the final moments.

The win means the Lakers improve to 25-27 but remain ninth in the Western Conference.

Embiid, LaMelo and Doncic star in defeats

Joel Embiid had 27 points and 14 rebounds but could not lift the Philadelphia 76ers as they went down 106-103 to the Washington Wizards. Spencer Dinwiddie (14 points, 12 rebounds, 10 assists) had a triple-double for the Wizards, while Kyle Kuzma added 24 points.

LaMelo Ball was excellent in a losing side as well, providing a career-high 38 points including four triples with six rebounds and nine assists as the Charlotte Hornets went down 113-107 to the Boston Celtics. Luka Doncic also had 40 points as the Dallas Mavericks lost 120-114 in overtime to the Oklahoma City Thunder.

Ja Morant had 23 points, four rebounds and nine assists as the Memphis Grizzlies won 120-108 over the New York Knicks, while the Utah Jazz snapped their five-game skid with a 108-104 win over the Denver Nuggets.

Nets skid extends to six games

The Brooklyn Nets slumped to their sixth straight defeat, their worst skid since January 2020, after a 112-101 loss to the Sacramento Kings. James Harden, nursing a sore hand, only managed four points shooting two-of-11 from the field, which was his lowest return since May 15 last year.

Raul Jimenez's 80th-minute penalty has earned Mexico a hard-fought 1-0 victory over Panama to open up a four-point gap between the sides in the race to qualify for Qatar 2022.

Jimenez returned after missing the past two games with a calf injury to be a constant threat for El Tri, before converting the spotkick won by Diego Lainez in Mexico City on Wednesday.

The late strike eased the pressure on El Tri head coach Gerardo Martino after Saturday's 0-0 home draw with Costa Rica, as third-placed Mexico moved clear of fourth-placed Panama in the CONCACAF playoff spot with three games to play.

Wolves forward Jimenez had the bulk of Mexico's chances, including having an early second-half goal disallowed by the VAR.

Lainez, who was introduced as a 66th-minute substitute for Hirving Lozano, won the penalty with quick feet after being upended by Abdiel Ayarza. Jimenez sent Panama goalkeeper Luis Mejia the wrong way with his cool finish.

In the fifth minute of stoppage time, the visitors almost grabbed a crucial late equalizer when Michael Amir Murillo pushed forward and glanced a header wide.

The United States took a big stride towards 2022 World Cup qualification with three set-piece goals in a 3-0 victory over already-eliminated Honduras in freezing Minnesota on Wednesday.

Weston McKennie, Walker Zimmerman and substitute Christian Pulisic netted the goals as USA moved to 21 points from 11 games, rebounding from their 2-0 loss to Canada last time out as they chase qualification for Qatar 2022 after missing out four years ago.

The victory was crucial for second-placed USA to move clear of the chasing pack, with third-placed Mexico to host fourth-placed Panama later on Wednesday.

The temperature dropped to minus 18 degrees in the first half with players from both sides permitted to wear full overhead balaclavas and hand warmers.

Juventus midfielder McKennie opened the scoring with an eighth-minute near-post header from Kellyn Acosta's free-kick, before Nashville defender Zimmerman bundled home a second in the 37th minute from a set piece.

McKennie and Timothy Weah almost combined for a third in the 50th minute only to be thwarted by substitute Honduras goalkeeper Edrick Menjivar.

Chelsea star Pulisic was introduced in the 64th minute and scored three minutes later, volleyed home a loose ball from a corner after Zimmerman's knockdown. Pulisic also had a late goal disallowed for offside.

Top seed Diego Schwartzman cruised into the quarter-finals of the Cordoba Open after a straight-sets win over countryman Juan Pablo Ficovich on Wednesday.

World number 14 Schwartzman triumphed 6-3 6-2, converting three of five break points to win in one hour and 10 minutes.

Schwartzman will face Colombian lucky loser Daniel Elahi Galan who progressed with a 6-2 3-6 6-1 victory over Jaume Munar.

Eighth seed Pedro Martinez was eliminated by Argentina wildcard Juan Ignacio Londero 6-3 7-6 (7-3).

Londero will face Serbian Nikola Milojevic, another lucky loser, who got past wild card Tomas Martin Etcheverry 6-3 7-6 (7-4).

New York Jets offensive lineman Cameron Clark will retire at the age of 24 due to a spinal cord injury.

Clark's agent confirmed the decision with the risk of paralysis if he continued to play, having suffered the injury in a training camp.

The 2020 fourth-round pick was injured on August 3 in Jets training and was motionless for several minutes.

At the time, the Jets labelled the injury a spinal cord contusion and said he would make a full recovery but Clark missed the entire 2021 NFL season and has now opted to retire.

"Based on the advice of Dr. Andrew Hecht, a prominent orthopedic surgeon at Mt. Sinai Hospital in New York, Cameron will not be able to continue to play football for the New York Jets," Clark's agent Alan Herman told ESPN.

Jets head coach Robert Saleh told ESPN: "A great young man, with a bright future, I am thankful for Cameron's peace in making his decision, however bittersweet it may be.

"He made it to the league because of his talent, hard work and attitude and I have every confidence that they will all continue to serve him as he transitions to the next step."

Roger Federer still has the drive to return to the ATP Tour but is yet to run and is still months away in his recovery from a third knee operation.

The 40-year-old 20-time grand slam winner missed last month's Australian Open after a knee operation in August.

Federer has not played since a quarter-final loss to Hubert Hurkacz at Wimbledon last year and previously said he would be "incredibly surprised" if he was fit to play at the event in 2022.

"It's a very important next few months ahead of me," Federer said at a sponsor's event on Wednesday. "I'll know a whole lot more in April what my body is going to be like.

"Up until now I was not able to run yet and do the heavy workload. I hope that starts in the next couple of weeks and then we'll see how my body reacts.

"For now, the drive is there. I'm really motivated to do my work and what I'm allowed to do. I'd love to do way more, but the doctors are holding me back a bit."

The eight-time Wimbledon champion elaborated on his recovery, revealing he hopes to put weight on his knee again in the coming weeks.

"I can still not run. But I'm working daily in the gym," Federer said. "I really hope that I can put weight on my knee again in two to three weeks. Then we'll see how the body reacts so we can hit the ball again in April or May."

He added: "Of course I wish that everything could go quicker. But the doctors don't want me to overdo everything."

Rangers gave the Old Firm Derby away to Celtic, but Giovanni van Bronckhorst does not think it will be decisive in the Scottish Premiership title race. 

Celtic took the lead through Reo Hatate inside five minutes at an electric Parkhead on Wednesday and completely controlled the clash between the top two during the opening period. 

Hatate rifled in a brilliant second and two minutes later crossed for Liel Abada to make it 3-0 on the stroke of half-time. 

Rangers improved after the restart but were unable to stop their 21-game unbeaten run coming to an end, with Celtic replacing them at the Premiership summit and going a point clear. 

"It seemed like it was the first Old Firm game we'd played. We know what the Old Firm will bring, what we have to do … but it seemed like we weren't ready for it," Van Bronckhorst told Sky Sports. 

"You see the way we gave the goals away. It's the sharpness, I cannot say otherwise. It's not going with your man, not being ready for the battles. I think it was unbelievable the first half I saw. 

"I think our Old Firm game started in the second half. We were much better, much more aggressive and we played the second half really well. But in the first half we gave the game away. 

"It wasn't something I expected. When I see the trainings we had, the focus we had before the game, but when the whistle blew, we were just waiting for the goal to be scored. We were too naive and we deserved to be down 3-0 with the way we played. 

"We had an honest conversation in the locker room after the game.  

"We're not the first Rangers team to lose. I lost very big here as a player, but we eventually became champions that year. Of course, we wanted to win this game, but these games don't decide the championship. We still have many games to play and we have to be ready." 

The victory was Ange Postecoglou's first since taking charge of Celtic and ended a six-game winless run against Rangers in the league. 

The Australian was thoroughly impressed with how his team outplayed Rangers and believes there is still plenty more to come from the Bhoys. 

"Our first 45 minutes were outstanding; three great goals," Postecoglou told the BBC. 

"Our football was pretty special and their keeper pulled off some great saves. In the second half, we had to defend a bit more but we've been a team that can do that. It shows another layer. We knew the consequences, what it meant to our supporters, and we stood up. 

"Considering the context of the game and the opposition, I thought our football was outstanding. It's the kind of football team we want to be. It doesn't mean you disrespect or dismiss the opposition. We are still developing, but we want to take it to the opposition, and if we do that, we can take it to any opposition. 

"We've still got key players missing, very influential players. Some are just in the door. Reo Hatate and Matt O'Riley have played fewer than five games. Our target was not top spot, our target is to win things, and if we're going to win things, we have to keep improving."
