Frenkie de Jong is unsure of Barcelona's title credentials despite their improving LaLiga form.

De Jong scored the opener and created a late second for substitute Riqui Puig during Sunday's 2-0 win at Elche.

That made it four wins out of four for Barca in Spain's top flight since the turn of the year, although they will be 10 points behind Atletico Madrid having played a game more if the leaders are able to beat Valencia in Sunday's late kick-off.

"I'm not sure," he told LaLiga TV when asked whether Ronald Koeman's side are back in the title race.

"We have to win our games and we'll see where we end up towards the end of the season."

Nevertheless, the Netherlands midfielder has no doubt Barca are an improved side after a tough start to life under his former national team boss Koeman.

"Since the new year we're a lot better and we've played most of the games away from home and won all of them in LaLiga. We're in a better moment," De Jong said.

"I think [beating Elche] will do us good, we've worked hard, especially now in the new year. We're growing and improving as a team and hopefully we can keep improving."

De Jong's tally of five goals across his season-and-a-half with Barca has already bettered his total of Eredivisie strikes for Ajax (four) across five campaigns, and the 23-year-old also feels that the imperative to improve applies to him personally, even after a man-of-the-match display.

"Yes, I do think I can play better but it’s not only about goals and assists," he added. "Of course I'm happy but there's more to come."

Frenkie de Jong played a prominent role as Barcelona beat LaLiga strugglers Elche 2-0 to stay in touch with the leading pack.

Lionel Messi completed his two-match suspension for a red card during the Supercopa de Espana defeat to Athletic Bilbao and Barca struggled to create clear chances in his absence against well-organised opponents.

But an error from Diego Gonzalez allowed De Jong to take advantage in the 39th-minute – the Netherlands international unlikely to score an easier one than his fifth LaLiga goal.

A minute from time, De Jong then turned provider as he crossed for Riqui Puig to head home, ensuring Barca are three points behind Real Madrid, although they will be 10 points shy of Atletico Madrid again if the leaders are able to beat Valencia later on Sunday.

Manchester United boss Ole Gunnar Solskjaer left Bruno Fernandes out of his starting line-up for Sunday's FA Cup clash with Liverpool.

Fernandes, who has been United's shining light since arriving from Sporting CP almost 12 months ago, was only a substitute for the fourth-round game.

This season he has scored 15 goals and supplied nine assists in 28 games across all competitions from his advanced midfield role, but there have been questions asked about his form in recent weeks.

He has just one goal and no assists in four Premier League appearances since the turn of the year.

Into the United team went former Ajax midfielder Donny van de Beek as Solskjaer decided the game presented a chance to rotate his squad, making five changes to the side that won 2-1 at Fulham on Wednesday.

Solskjaer explained why Fernandes did not start, saying on BBC One: "It's rotation in the squad.

"Donny needs to be playing games as well and it's a big game for Donny to come into.

"He's done nothing wrong when he's been around the club so I'm looking forward to seeing him in there."

Premier League leaders United also brought in goalkeeper Dean Henderson, centre-back Victor Lindelof, midfielder Scott McTominay and forward Marcus Rashford, as David De Gea, Eric Bailly, Fred and Anthony Martial dropped out.

Liverpool also showed five changes as Jurgen Klopp looked for a response to Thursday's shock 1-0 home defeat to Burnley, which ended a 68-game unbeaten run at Anfield in the Premier League.

Teenage centre-back Rhys Williams came in for the absent Joel Matip, while James Milner and Curtis Jones were selected as Xherdan Shaqiri and Alex Oxlade-Chamberlain dropped to the bench.

Sadio Mane and Divock Origi were also substitutes as Klopp gave starts to Mohamed Salah and Roberto Firmino, with the Old Trafford clash coming a week on from these two sides battling out a dreary goalless draw at Anfield in the league.

Robert Lewandowski became the first player in Bundesliga history to score in eight successive away games and Thomas Muller scored twice as leaders Bayern Munich cruised to a 4-0 win over Schalke.

Second-place RB Leipzig suffered a shock loss to Mainz 05 on Saturday and Bayern took full advantage at the Veltins-Arena on Sunday, moving seven points clear at the top.

Schalke are bottom of the table with one win all season but they more than matched the European champions before Muller's 33rd-minute breakthrough.

Muller doubled his tally late on after Lewandowski had scored his latest record-breaking goal early in the second half, before David Alaba added further gloss at the death.

The division's leading scorer Lewandowski glanced over the crossbar from close range early on before a better chance came and went for Mark Uth, who headed straight at Manuel Neuer from five yards out.

Ralf Fahrmann was called into action with a fine double save to keep out Lewandowski's free-kick and Serge Gnabry's follow-up attempt. 

Gnabry went close again when glancing the side-netting with a header he should have put away, but Bayern were in front seven minutes later through Muller's powerful header. 

The attacking midfielder met Joshua Kimmich's back-post delivery and made no mistake in beating Fahrmann for his eighth league goal of the campaign. 

Gnabry thought he had added a quickfire second after Leroy Sane's initial effort was parried, only for the offside flag to go up against the former Schalke winger.

But the Bavarian giants did double their advantage early in the second period as Lewandowski controlled Kimmich's long ball, held off two defenders and slotted under Fahrmann.

It is the 11th successive Bundesliga game in which Lewandowski has scored against Schalke and he nearly added another, dragging wide from 18 yards 20 minutes from time.

Schalke are now without a win against Bayern in 21 league matches and badly faded in the closing stages, with Muller heading in from another Kimmich delivery and Alaba adding a fourth with a 30-yard drive that squirmed under Fahrmann.

Joe Root treated his England team-mates to an education in how to play spin bowling following his domination of the Sri Lanka attack, says Jos Buttler.

Captain Root backed up his 228 in the first Test victory with a monumental 186 in Galle on Sunday, falling cruelly to a run out from the final ball of the day.

Oshada Fernando's quick thinking at short leg meant England closed day three on 339-9 - a first-innings deficit of 42.

Despite that giving Sri Lanka a slight edge in their bid to secure a series-levelling win, attention afterwards understandably focused upon Root, who passed Geoffrey Boycott, Kevin Pietersen and David Gower to go fourth on England's all-time list of Test run scorers over the course of a fabulous knock.

"It was quite an amazing innings," Buttler said. "To back up his double hundred in the first Test, to show the mental and physical application to go again.

"It's been a masterclass in batting against spin. It's been a great education for all of us watching from the sidelines.

"We've thoroughly enjoyed watching him and we're gutted for him getting out in that fashion at the end of the day."

Buttler, who was the only other England batsman to pass 50, shared a 97-run stand with Root for the fifth wicket and also marvelled at his skipper's powers of endurance.

The 30-year-old Root motored on during the evening session despite cramps and back pain demonstrating the toll taken.

"For all eight days of the series so far he's been out on the field," Buttler said. "This game feels a lot hotter and lot more draining than the first game, [which had] rain breaks.

"We have to praise not only the tactical and technical aspect of his game, but the physicality and concentration to apply himself for so long.

"Once again, to back up the first Test is quite amazing really."

Lasith Embuldeniya carried the fight for Sri Lanka with superb figures of 7-132, but even the in-form slow left-armer could not escape punishment from Root, who swept with authority and even unfurled an audacious switch hit to fine effect.

"There were some quite amazing shots, really," added Buttler, who is consistently England's most innovative strokemaker across all formats. "It show the confidence and the skill level is amazing.

"He even played a little late cut left-handed. It's been great to watch. His skill level is second to none."

Kepa Arrizabalaga made another blunder and Timo Werner missed a penalty but Tammy Abraham's hat-trick got Chelsea past Luton Town with a 3-1 victory at Stamford Bridge.

Abraham's quickfire double put Chelsea in control early in the FA Cup fourth-round tie on Sunday, as last season's runners up seemed to be heading for a comfortable success.

Yet Kepa, brought in as one of seven changes made by Frank Lampard from Tuesday's defeat at Leicester City, enabled Luton to haul themselves into the contest when he failed to keep out Jordan Clark's effort.

Abraham's third goal 16 minutes from time ultimately set up a fifth-round trip to Barnsley, though Werner's woeful run in front of goal continued when his late spot-kick was saved.

Hertha Berlin have sacked head coach Bruno Labbadia and general manager Michael Preetz following a poor run of form.

Saturday's 4-1 home loss to fellow strugglers Werder Bremen proved to be the final game in charge for Labbadia, who was only appointed nine months ago.

Labbadia guided Hertha from 13th to 10th upon taking over from Jurgen Klinsmann last season but the Old Lady have failed to push on this term.

They have lost three of their previous four games and have won just four of their 18 league matches all season.

With the capital club only two points above the relegation play-off spot having played a game more than 16th-place Cologne, the board has now taken action.

Hertha confirmed the news on their official website on Sunday, with chairman Carsten Schmidt concerned about his side's slide down the division.

"Week in, week out, Bruno and his coaching staff have invested a lot of hard work into the team's development and we would like to thank him greatly for that," Schmidt said. 

"Ultimately, however, the return of 17 points from 18 games leaves us in a very precarious situation. 

"After much deliberation, we feel that a change of head coach can give the team fresh impetus. We will clarify his successor as head coach in the coming days."

Preetz has spent close to a quarter of a century at Hertha, including the past 12 years as part of the management staff.

Sporting director Arne Friedrich will take over Preetz's duties until the end of the campaign, when a permanent replacement will be announced.

President Werner Gegenbauer said: "Hertha have a lot to thank Michael Preetz for. During his time here, he has established Hertha as a Bundesliga club.

"But looking at the development both in the last campaign and the current one, we have decided to take a different direction for his role in the future. 

"Nevertheless, I want to express my sincerest thanks to Michael Preetz for his fine work for so many years."

Hertha were among the biggest spenders in European football in 2020, bringing in the likes of Krzysztof Piatek, Matheus Cunha and Lucas Tousart.

Piatek and Cunha have scored a combined 19 goals in 60 Bundesliga appearances since arriving in January last year, with the latter responsible for 11 of those goals.

While their big-name forwards have failed to fire, Hertha have also struggled defensively. Only bottom-two sides Mainz (38) and Schalke (44) have conceded more than their 32 goals in 2020-21.

Hertha's next permanent head coach will be their fifth in the past two years with Pal Dardai, Ante Covic, Klinsmann and now Labbadia having departed since June 2019.

Arthur scored his first goal for Juventus as the defending champions beat Bologna 2-0 to go fourth in Serie A.

Juve claimed their first trophy under boss Andrea Pirlo with a Supercoppa Italiana victory over Napoli in midweek and got their title bid back on track at Allianz Stadium on Sunday.

Arthur's deflected first-half strike and a Weston McKennie header moved the Turin giants seven points adrift of leaders Milan with a game in hand.

Juve, beaten by Inter last weekend, were not at their best but although Bologna had their chances, they are now without a win over the Bianconeri in 19 attempts.

Pirlo's side took the lead in fortuitous fashion after 15 minutes, when Arthur's long-range drive struck Jerdy Schouten and gave wrongfooted goalkeeper Lukasz Skorupski no chance.

Skorupski produced a fine double save to prevent Juve from increasing their advantage, using his feet to deny Federico Bernardeschi from close range after palming away a strike from Cristiano Ronaldo.

Juan Cuadrado fired wastefully off target before Roberto Soriano went close to equalising late in the first half with a shot from inside the penalty area that flashed wide.

A fine reflex save from Wojciech Szczesny prevented Cuadrado's header from gifting Bologna an own goal early in the second half and the Juve keeper once again had to be alert keep out Riccardo Orsolini's left-footed strike.

Bologna were made to pay for their profligacy when an unmarked McKennie nodded in Cuadrado's corner 19 minutes from time.

Skorupski denied McKennie a quickfire double with a great reaction save before preventing Alvaro Morata from adding a third goal at his near post.

The busy Skorupski beat away Adrien Rabiot's left-footed shot and saved a powerful Ronaldo strike as Juve saw out a comfortable win.

Kyrie Irving revelled in a hard-fought victory for the Brooklyn Nets over the Miami Heat after he went into a "winning" zone in the fourth quarter.

The Nets got back on track after consecutive defeats to the Cleveland Cavaliers by overcoming the Heat 128-124 on Saturday.

Up against an inspired Bam Adebayo, who scored a career-best 41 points, Brooklyn relied on the star power of Irving, Kevin Durant and James Harden to get them over the line.

"It's not every day you see this collection of guys playing together in NBA history, so we want to take full advantage of that," Irving told reporters.

Irving proved decisive, with 18 of his 28 points coming in the fourth quarter, including three three-pointers.

"It's winning time," Irving told reporters while explaining his mentality in the final quarter.

"I've always said that throughout my career. When it gets down to that point, obviously you just want to buckle down on the defensive end, get stops, and I felt like we did that.

"We had two losses where we had to learn a lot very quickly and we just moved on to the next night. I feel like we gave the effort in spurts, and obviously we want to have more consistency in that, and that'll take time. I'm happy with the effort."

While Durant topped the Nets' scoring with 31 points, Harden also stepped up to the plate, posting 12 points and 11 assists with seven rebounds.

"It feels good not to have to score so much to give ourselves a chance to win a game," eight-time All-Star Harden said.

"I can go out there and just be a playmaker and shoot my shot when it's available and still get guys involved, and still have a chance to win the game.

"That's a change. But for me just being the player that I am, impacting the game in other ways other than scoring."

Durant, meanwhile, hailed Irving as the difference-maker.

"You've seen how special and talented and hard-working Kyrie is," Durant told reporters. "He works on all of those shots every day and he comes in with that mentality that especially late in the games he'll have to knock those down for us.

"He's an all-world player, he's a great team-mate but when the ball is in his hands late in the game, our team is just so unpredictable because he can make the pass, he can score in the mid-range, score in the three-point area, get to the basket and we've got weapons around him that makes it tough to guard.

"We're going to need that from him going forward and he was phenomenal in the fourth."

Though the Nets' star trio ultimately claimed the win, Miami's Adebayo was at his best, finishing with five rebounds and nine assists in addition to his 41 points.

"It was about time Bam had 40 in terms of getting a lot of those moves that he's been working on in the offseason," said Irving, who – against coronavirus protocols – attempted to swap jerseys with Adebayo on the court before a Heat official intervened.

"Just watching him grow since high school, be able to take over at this point for kind of an undermanned Miami team, it's good to see."

England captain Joe Root was denied a second consecutive double century when he was run out for 186 from the final ball of day three in a gripping second Test against Sri Lanka.

The great Wally Hammond remains the only Englishman in history to have passed 200 in consecutive matches, although Root looked certain to join him as he took the fight to the hosts in majestic fashion

Root is now fourth in England's list of all-time Test runs scorers, having surpassed Geoffrey Boycott, Kevin Pietersen and David Gower over the course of a truly magnificent knock, which accounts for the bulk of England's 339-9 – a first-innings deficit of 42.

Before Oshada Fernando collected sharply at short leg to catch the visiting skipper out of his ground, this was another England innings that pitted two supreme performers at the top of their game against one another, with Sri Lanka left-arm spinner Lasith Embuldeniya taking 7-132 in a near lone response to Root's brilliance.

Embuldeniya's wide angle on the crease and ability to find biting turn accounted for openers Dom Sibley and Zak Crawley on day two, and he saw off Jonny Bairstow and Dan Lawrence in similar fashion on Sunday.

Bairstow could only add four to his overnight 24 after a review showed a faint inside edge onto pad that was pouched by Oshada, while Lawrence nicked a beauty to Lahiru Thirimanne at first slip.

Root's immaculate sweep shot meant he was able to largely avoid such problems, even punishing the excellent Embuldeniya with his audacious switch hit.

Substantial support for the captain finally arrived in the form of Jos Buttler, whose crunching off-side drive and reverse sweep were in good order during a fifth-wicket partnership of 97.

Somewhat unfortunately, the latter shot would prove Buttler's downfall after lunch when, on 55, he struck a delivery from debutant Ramesh Mendis (1-48) into his boot and it looped up for the ever-alert Osada to catch.

The Thirimanne-Embuldeniya combination accounted for Sam Curran, Dom Bess and Mark Wood, although Bess played tidily for an important 32 in a stand of 81 as Root motored on despite beginning to struggle with cramps and back pain.

It was a monumental effort over the course of 309 deliveries that did not deserve its cruel sting in the tail.

Reggie Miller hailed Stephen Curry as an inspiration after the Golden State Warriors guard went past him on the NBA's all-time three-pointers list.

The Warriors lost 127-108 to the Utah Jazz at Vivint Smart Home Arena on Sunday but Curry had a moment to savour when he sunk his 2,561st effort from deep.

It leaves only Ray Allen ahead of Curry on 2,973 and Miller joined the Warriors' postgame media call via Zoom to pass on some warm words.

"Congratulations, this is an unbelievable achievement," he said, accompanied on the call by his son - a self-confessed huge fan of Curry.

"I know the work is not done, I know you're chasing Ray, but you are an inspiration to so many little ones, like mine.

"I'm so proud of all the work because I know what goes into that.

"I know the countless hours, when it's easy to go hang with your boys, hit the clubs, sleep, do other things.

"But you're in the lab getting your work done."

Curry said going past Miller was "pretty special" and "something I've been looking forward to for a very long time".

"That means a lot, Reg. I appreciate it," he replied.

"Like you said, I know I have a lot more to take.

"That competitive juice, the work that goes in, the appreciation of every game I get to play - to shoot the ball at this level and follow your footsteps in that regard means a lot.

"You and Ray, to have two guys to have reached back and encouraged me the way you have means a lot. I appreciate you, man."

Even though he still needs more than 400 three-pointers to make up the ground on Allen, Curry's rate of scoring means his move to the top of the pile should only be a matter of time.

Over the course of a 715-game NBA career, he averages 3.6 per game and boasts a 43.3 per cent success rate from beyond the arc.

Dustin Poirier declared "I'm the champ" after defeating Conor McGregor by technical knockout at UFC 257 in Abu Dhabi on Sunday.

A string of punches to McGregor's head in the second round made Poirier a leading contender for the UFC lightweight title, which is still held by Khabib Nurmagomedov despite the Russian having retired.

Poirier said he would be open to a rematch with McGregor or a bout with Nate Diaz but ruled out a fight against Michael Chandler, who defeated Dan Hooker on his UFC debut in the co-main event.

Asked if a fight with former Bellator lightweight champion Chandler interested him, Porier said: "No, it does not. Respect to Chandler, great win over a guy, but to come in and beat a guy I just beat and get a title shot?

"Dude, I've been 27, 28 fights in the UFC, trying everything, fighting the toughest of the toughest guys to get my hands on gold. He should fight Charles Oliveira or something, let them go at it.

"That doesn't really interest me at this point. I'll go and sell hot sauce if that's the case.

"It's not even my position, I've just been putting in the work, that's why I can sit here and talk about it because I've been in the division and the UFC for a long time fighting the best of the best to him.

"No disrespect to him … it's just my feelings towards the division and the sport. I feel like I lost to Khabib, I came out and put on a fight of the year for you guys, got my hand raised against a top-five opponent after that, then I come in here and Khabib doesn't want to come back, and one of the biggest fights you can get I knock this guy out too.

"Khabib reiterates he doesn't want to fight anymore. Dude, I'm the champ.

"Fighting a new guy to the UFC who just beat a guy whose coming off a loss that I just beat for the belt, that's not exciting to me."

Poirier ranked the victory over McGregor as one of his best, particularly because the Irishman won their first meeting in 2014 and had never been knocked out before.

"It's up there, especially finishing a guy who's never been finished like that, it's up there man," he said.

"Touching that UFC interim belt was so important to me, and putting my hands on the undisputed world title before this is all said and done is what I want to absolutely do, but this is a big one."

Poirier lost his first and only shot at the title when he was submitted at UFC 242 by Nurmagomedov, who bowed out after making Justin Gaethje tap at UFC 254 last October.

Asked whether Gaethje or Oliveira was more deserving of a chance to fight him for the lightweight belt, he replied: "Oliveira, because he's never had the opportunity.

"Gaethje just came out here and got beat. As I did. Not a knock on Gaethje, but he lost. Oliveira probably, or let them fight to see who gets it. There are so many tough fighters in the 155-pound division."
