Arsenal head coach Mikel Arteta has defended the decision to let Pierre-Emerick Aubameyang join Barcelona and not replace the striker in January.

The Gunners allowed Aubameyang to depart on a free transfer in the last window after stripping the 32-year-old of the captaincy following a disciplinary issue.

The Gabon international, who reportedly agreed a significant pay cut to move to Barca, did not play for Arsenal after December 6, but has started in an impressive run of form for the Catalan club.

Aubameyang netted a hat-trick in a 4-1 thrashing of Valencia, becoming just the fourth player to score in LaLiga, the Premier League, Bundesliga and Ligue 1 in the 21st century.

He followed that up with strikes against Napoli and Athletic Bilbao to make him LaLiga's first African player to score in three games in a row in all competitions, since Youssef En-Nesyri for Sevilla in March 2021.

But Arteta does not regret the decision to let the forward leave, despite the Gunners appearing short-handed with just Alexandre Lacazette and Eddie Nketiah to call upon up top.

"We always make decisions in the best interests of the club and to get the best performances from the team," Arteta told Sky Sports when asked about Aubameyang's exit.

"We made that decision as three parties. One was the club, one was Auba, and the other was Barcelona. The three of us believed it was the right thing to do.

"That was a possibility, but I think when you have a clear direction and process of how you make your decisions, you have to be ruthless."

Looking at how the decision angered some Arsenal supporters, Arteta added: "You have to have a certain courage and consistency in those decisions.

"If one decision is to only bring in players we can afford, who are going to make the team much better straight away, and who are sustainable for our future, then that should be the case.

"So, even if you are tempted to do something, but you think it's going to bring you trouble in the coming months or years, you should not do it. I think we were brave not to do it."

Indeed, Arsenal have improved markedly since Aubameyang's departure, winning seven of nine top-flight games since the last time the former Borussia Dortmund star played.

Lacazette has filled the void that Aubameyang left, with his role in Jose Sa's late own goal securing a 2-1 win over Wolves in their last outing, and Arteta has been pleased with the 30-year-old, who has taken on the captaincy for now.

"Laca has a really important quality, which is that he makes the people around him better," Arteta said. "He understands the game really well, he's a really intelligent player and his work-rate is phenomenal.

"I think he's been very unlucky not to score another four, five, six goals in this period. We want to give him the confidence and he will do that but, for me, he scored last week against Wolves. He was there to make the final action to win the match."

Arsenal will look to continue their pursuit of the Champions League qualification spots when they travel to strugglers Watford on Sunday.

Ravindra Jadeja took up the mantle for India as his unbeaten 175 guided Rohit Sharma's side into a commanding position on day two of the first Test against Sri Lanka.

Rishabh Pant fell short of a century on day one in Mohali, but day two also belonged to the hosts, who were 446 runs ahead at stumps on Saturday.

Jadeja resumed on 45, yet the world's second-best Test batsman had ticked over 100 by the time lunch arrived, with India at 468-7 after ending day one on 357-6.

Ravichandran Ashwin reached 61 from 82 deliveries, with his stand including eight fours, before falling to Suranga Lakmal (2-90) in the first session.

Jayant Yadav was dismissed for two shortly after lunch, but Jadeja went on the offensive, putting on a century stand for the ninth-wicket alongside Mohammed Shami (20 not out) before Sharma declared on 574-8.

Virat Kohli, playing in his 100th Test, received a guard of honour from his team-mates as India headed out to field, though Sharma's hosts were made to wait for a breakthrough as Sri Lanka's openers started in solid fashion after tea.

That breakthrough came in the 19th over when Ashwin trapped Lahiru Thirimanne leg before wicket. The opener sent it upstairs, but the review merely confirmed the decision.

Dimuth Karunaratne (28) followed soon after, again unsuccessfully reviewing for an lbw decision, albeit this time on umpire's call.

Jasprit Bumrah thought he had bowled Pathum Nissanka, only to have overstepped his mark, but he got his wicket when Angelo Mathews was given out lbw, with the review again confirming umpire's call.

Dhananjaya de Silva also went lbw, attempting an unwise sweep from Ashwin as India capped off a fine day.

Sri Lanka's review misfortune

Sri Lanka fell foul of an umpire's call twice, so it would be harsh to say they wasted their reviews on trying to overturn the dismissals of Karunaratne and Mathews.

De Silva did not even attempt to get a reprieve from the technology, though Charith Asalanka did use one wisely to avoid being given out late on to Jadeja.

Jadeja stakes his claim

India's Jadeja is arguably the best all-rounder in world cricket at the moment, and he proved his quality with his exceptional knock, which included three sixes and 17 fours.

His 175 is a new personal high in Test cricket for the 33-year-old and came at a strike rate of 76.75. It might just have put this match beyond the tourists, too.

Nikita Mazepin said he was "very disappointed" after Haas sacked him from their driver line-up and cut lucrative ties with Russian backer Uralkali.

Russian racer Mazepin was consistently a backmarker during the 2021 season, his first year on the F1 grid, and was frequently outperformed by team-mate Mick Schumacher.

It has been Russia's invasion of Ukraine that has cost him his seat for 2022, however, rather than his results on the track.

Mazepin's father, Dmitry, has close ties to Vladimir Putin, holding face-to-face business talks with the Russian president as recently as January. Dmitry Mazepin is deputy chairman of Uralkali, the potash producer that has been a major financial backer of Haas.

As well as ousting 23-year-old Mazepin, Haas announced the commercial link with Uralkali has also been scrapped with immediate effect.

Haas removed the Uralkali logos from their cars for the final day of pre-season testing in Barcelona last month, in keeping with wider efforts to impose sporting sanctions on Russia.

The Russian Grand Prix for 2022 has been cancelled, with F1 announcing this week it has terminated its deal for future races in the country.

Mazepin responded to news of his dismissal by Haas on Saturday, stating: "I am very disappointed to hear that my F1 contract has been terminated.

"While I understand the difficulties, the ruling from FIA plus my ongoing willingness to accept the conditions proposed in order to continue were completely ignored and no process was followed in this unilateral step."

He did not clarify further on those points, but said he would elaborate on his statement "in the coming days".

"To those who have tried to understand, my eternal thanks," Mazepin added. "I have treasured my time in F1 and genuinely hope we can all be together again in better times."

Before Haas announced their decision, it had already been revealed that Mazepin would be banned from competing at the British Grand Prix.

J.B. Bickerstaff worked with James Harden while the duo were with the Houston Rockets, and the Cleveland Cavaliers coach continues to be impressed by the Philadelphia 76ers man.

Harden registered 25 points, 11 assists and three rebounds as the in-form Sixers won a fifth straight game on Friday, beating the Cavs 125-119.

While Joel Embiid failed to hit his usual high marks, scoring 22 points, Tyrese Maxey stepped up with 33 points, including five threes.

Harden added two three-pointers to the 76ers tally, moving onto 2,559 for his career, meaning he only needs one more to match Reggie Miller for third on the all-time list (regular season only).

"He sees the game a step ahead," Bickerstaff told reporters when asked about Harden.

"He's not one of those guys that's just going so fast he's waiting for the offense to react.

"He's forcing the defense to react. He's one of the most creative decision-makers and passers in our game. He also knows when to make the play that's right in front of him."

Reflecting on his team's display, Bickerstaff – who was fined $20,000 after being ejected from the game during Monday's defeat to the Charlotte Hornets – was satisfied despite a third-straight loss.

"We felt and looked like ourselves for the first time in a while," he said. "We just happened to run into a really good basketball team."

Harden finished with at least 20 points and 10 assists for a third game in four, yet the former Brooklyn Nets shooting guard was not thrilled with his own display.

"I've got to do a better job of being more solid, I've got to be smarter so I can be out there and help my team," he told reporters.

Yet Maxey stepped up regardless, and Harden was impressed.

"On any given night, it can be any one of us to go off," Harden said of his team-mate. "Tyrese really picked it up for us tonight." Coach Doc Rivers, meanwhile, labelled Maxey "a fearless kid".

Giannis Antetokounmpo and Jrue Holiday called for reigning NBA champions the Milwaukee Bucks to keep improving after they battled past the Chicago Bulls.

The Bucks edged out the Bulls 118-112, with Holiday finishing on 26 points, while Giannis Antetokounmpo had 34 points and 16 rebounds as Milwaukee made it three wins on the spin.

It was not all straightforward for Mike Budenholzer's side, though, given they went from leading by 14 in the second quarter to trail by seven through the third.

However, Holiday delivered 15 points in the fourth quarter as the Bucks rallied to another victory, just as they did at the Miami Heat to triumph by one on Wednesday.

"It's just a feeling and you know you've got to turn it on," Holiday said.

"It's time for us to lock-in. It's time for us to just concentrate, be aggressive and make good plays, smart plays, down the stretch."

The Bucks are now tied with Chicago for the Central Division lead, both sat on 39-25, with Milwaukee next hosting the NBA-leading Phoenix Suns on Sunday, with the Bulls going up against the Philadelphia 76ers a day later.

"We got to keep it up," Antetokounmpo said. "If good things are going on, you got to keep waking up the next day and keep learning something new, keep evolving, keep improving."

Milwaukee did well to limit a star-studded Bulls line-up. Zach LaVine headed the Chicago scoring with 30 points, while DeMar DeRozan managed 29 but finished 11 for 30 from the field.

DeRozan believes Milwaukee displayed their championship credentials.

"I felt like we competed," he told reporters. "It came down to the last couple minutes. They're defending champs for a reason."

Formula One team Haas have cancelled the contract of Russian driver Nikita Mazepin amid the Ukraine crisis.

Mazepin's father, Dmitry, has close ties to Vladimir Putin, holding face-to-face business talks with the Russian President as recently as January.

Dmitry Mazepin is deputy chairman of Uralkali, the potash producer that has been a major financial backer of Haas.

As well as ousting 23-year-old Mazepin, who was the only Russian with an F1 drive for the 2022 season, the commercial tie-up with Uralkali has also been scrapped.

It comes as Russia's invasion of Ukraine continues. Thousands have reportedly been killed since the start of the attack on February 24, including many civilians.

Haas said in a statement on Saturday: "Haas F1 team has elected to terminate, with immediate effect, the title partnership of Uralkali, and the driver contract of Nikita Mazepin.

"As with the rest of the Formula 1 community, the team is shocked and saddened by the invasion of Ukraine and wishes for a swift and peaceful end to the conflict."

Haas removed the Uralkali logos from its cars for the final day of pre-season testing in Barcelona last month.

The team's other driver is Mick Schumacher, son of German great Michael Schumacher. Haas have yet to announce who will replace Mazepin in the new season, which gets under way in Bahrain in two weeks' time.

The Russian Grand Prix for 2022 has been cancelled, with F1 announcing this week it has terminated its deal for future races in the country.

Elina Svitolina saw her hopes of delivering an emotional title for Ukraine ended by Camila Osorio in a tough quarter-final loss at the Monterrey Open.

Top seed Svitolina wore the yellow and blue colours of her home country, which has come under attack from Russia's military in the past fortnight.

However, the former world number three could not capitalise on a fast start, or a big lead in the deciding set, as she slipped to a 1-6 7-5 7-6 (7-5) defeat in two hours and 33 minutes.

Svitolina held a 4-1 lead in the third set, but 20-year-old Colombian Osorio recovered the double break to edge out the 2020 champion, sealing the win in a deciding tie-break.

That was the third tight three-set battle of the day, with Brazil's Beatriz Haddad Maia earlier scoring a 4-6 6-4 7-6 (9-7) win over Marie Bouzkova, and Nuria Parrizas Diaz achieving a 6-3 1-6 6-4 victory in an all-Spanish clash with Sara Sorribes Tormo.

Parrizas Dias will face Osorio in Saturday's semi-finals, while Haddad Maia faces a tussle with US Open runner-up Leylah Fernandez, who was a late-night 7-6 (7-4) 6-4 winner against China's Wang Qiang.

Reigning NBA champions the Milwaukee Bucks claimed another big win on Friday as they toppled the Chicago Bulls 118-112.

Jrue Holiday came up big down the stretch to finish on 26 points, while Giannis Antetokounmpo had 34 points and 16 rebounds as the Bucks made it three wins on the spin.

While the Bucks are regaining form at the right time, the Bulls have now lost four on the bounce, though they hold an identical 39-25 record to Milwaukee.

Holiday hit the game-winning layup with less than two seconds left in the Bucks' win over the Miami Heat on Wednesday and he scored 15 points in the final quarter to help ensure the Bucks' 14th win against the Bulls in their last 15 meetings.

DeMar DeRozan has 29 points but was kept well contained overall, with Zach LaVine top scoring for Chicago with 30.

It was far from plain sailing for the Bucks, however, with Chicago having overturned an initial 14-point deficit to lead by seven after the third quarter.

Suns edge out Knicks as Randle's temper flares 

Next up on the Bucks' tough run are the NBA-leading Phoenix Suns, who scraped onto 51 wins for the season with a 115-114 triumph over the New York Knicks.

Cameron Johnson hit a buzzer-beating three-pointer to snag a comeback victory and finish with a career-high 38 points in the process.

The Suns, without Chris Paul and Devin Booker, looked set to lose out with the Knicks leading by 14 in the third quarter, only for Julius Randle to be ejected after a confrontation with Johnson.

Sixers make it five in a row

The Philadelphia 76ers reeled off a fifth straight win as they dispatched the Cleveland Cavaliers 125-119.

James Harden had 25 points and 11 rebounds to continue his strong start, while Joel Embiid got a relatively low, by his standards, 22 points on the board. That was no matter for Philadelphia, though, as Tyrese Maxey scored 33 points, with his haul including five three-pointers.

The Utah Jazz had a shocker as they went down 124-90 to the New Orleans Pelicans, Shai Gilgeous-Alexander's 33 points was not enough as the Oklahoma City Thunder lost to the Minnesota Timberwolves, and there were victories for the Houston Rockets, the Atlanta Hawks, the Detroit Pistons and the Orlando Magic.

Former Ukrainian tennis player Sergiy Stakhovsky is "pretty sure" he is on a Russian army target list after leaving his family to take up arms in defence of his country.

Stakhovsky, 36, recently returned to Kyiv to be part of the armed resistance following Russia's invasion of Ukraine.

The attack started last Thursday and it has continued since, with Ukrainian civilians subsequently arming themselves to fight for their country.

Stakhovsky has been especially active with media duties in the past few days, and as such he believes himself to be a marked man for speaking out against Vladimir Putin and Russia.

But the 36-year-old said he has been driven by a moral compass to fight the Russian forces despite having no formal military training.

He told Stats Perform: "You have to be scared. I mean, if you don't [get] scared then you're stupid, I guess. Then of course, you need to calculate all the circumstances and everything that could come out of it.

"I mean, I'm pretty sure that I'm on a nice list of the Russian army to, not be really – let's say – treated well. But it is what it is.

"Russia is a dictatorship state. If you show resistance, if you show that you don't agree with what they do, if you show that you don't want to have them here, they put you to the ground.

"They don't really argue with you. It's a state which is controlled by one man and the system is so rotten that it just eats up everybody who is not willing, who is actually expressing a different mind.

"So of course, it is scary, it is unpleasant. But... I can be scared in any part of the world. It's not going to change anything."

Stakhovsky, a father of three, felt he had an obligation to return to Kyiv to fight rather than stay with his family.

But he accepts there is only so much Ukrainians can do with the love, prayers and support of the world, urging politicians to do more without selling Ukraine out, convinced surrender will doom many more for speaking out.

"I wouldn't want any father to make that choice [to fight] or to make the decision anytime, anywhere in the world," he continued. "It's something that you don't really want to do. It's not, there's no right choice.

"In this case, I have three kids, which I have to raise, and I have to look after and I want to enjoy them finally, after finishing my career. And instead of that I'm here in Kyiv with a gun and trying to prove a point that Russia is doing the wrong thing.

"Yes, I'm morally right, 100 per cent and all of Ukraine is right. Russia is at fault, but the whole world just seems not to… well, the people of the world they care. They care and they send their appreciation, their love and their prayers and their support, but it's not going to do justice.

"The politicians are the main players in this whole area, and if they don't step up, if they don't save lives – because after all, the most important part in all of it in life is life itself – if they have a chance to save everything starting from tomorrow, they should.

"But they should not on terms that [mean] we give up [in] Ukraine and we save lives [by surrendering], because that's killing lives because then after they surrender Ukraine, the Russian machine will find every single individual who was in the resistance, who was willing to fight, and they will kill him, or put him in prison, they will poison him, they would kill him, it doesn't matter how, but they will find a way to get rid of these people.

"And we're talking about more hundreds and thousands of people. Russia these days is a Soviet Union of the Stalin era. It's a machine which is killing people."

Viktor Hovland holds a two-shot lead at the half-way point of the Arnold Palmer Invitational after Rory McIlroy endured a disappointing finish.

Overnight leader McIlroy was not as sharp as he was on the opening day at Bay Hill but still looked in with a chance of retaining his status as pacesetter for much of the round.

That was until the 15th, when he needed three putts from 30 feet. He then missed a birdie opportunity on 16 and failed to save par from eight feet on 17.

The Northern Irishman ultimately finished at level par for the day with 72 – Hovland, who started on the 10th, carded 66, giving him the round of the day and the lead.

His score would have been even better had he not bogeyed the 13th, however he responded admirably to that set-back with three birdies in his next four holes.

Hovland added two more on the fourth and sixth to ultimately set the clubhouse lead as he moved to nine under for the tournament – McIlroy failed to rise to his challenge.

Joining McIlroy two shots back on seven under in a tie for second are Talor Gooch and Tyrrell Hatton, the latter of whom felt his four-under 68 was "pretty flattering".

Similarly, Hovland is not getting carried away with his position in the standings, particularly considering he was only two shots off the lead heading in the weekend last year and went on to finish 15 off the pace.

"I kind of try to forget the weekend here last year," Hovland told the PGA Tour. "I played really well the first few days, very similar to how I played so far this year.

"The course just gets harder and harder every single day, and it started blowing. A few too many bad swings and I ended up in bad spots and just didn't really take my medicine."

As for McIlroy, the four-time major champion was taken aback by how quickly conditions on the course changed from Thursday, adamant he will be better prepared on day three.

"Those are the sort of greens you expect to see late on a Sunday, not late on a Friday," McIlroy added. "It's going to be interesting to see where they go from here, but it's going to be a good test over the weekend.

"I'm glad I got 18 holes in those conditions because the course definitely changed a lot from when I played it yesterday morning to this afternoon. I'll be a little more prepared for it [on Saturday]."

Billy Horschel is one shot further back on six under, and then there's a three-shot gap to a group of seven – world number one Jon Rahm is at two under.

Patrick Reed, Henrik Stenson and Justin Rose were among those to miss the cut, which was set at three over par.

Barcelona have confirmed 18-year-old winger Pablo Torre will join the club from Racing Santander at the end of the season in a deal that could cost them more than €20million.

Spain youth international Torre, who will turn 19 in April, has signed a four-year contract, which contains a €100m release clause.

A technically gifted and tricky wide player, Torre made his first-team debut for Racing as a 17-year-old in July 2020 and went on to establish himself as a regular for the senior side in 2020-21.

This season, Torre has had a hand in 12 league goals in Group 1 of the Primera Division RFEF, Spain's third tier.

Real Madrid and Real Sociedad were also linked with the youngster, who reportedly had a €10m release clause, but Barca have beaten their rivals to the punch.

Barca will pay an initial €5m to Racing, but that could increase significantly depending on his development, with the deal structured similarly to that which brought Pedri to Camp Nou from Las Palmas.

Torre will initially link up with Barca B in pre-season, though the route from the second team to the senior side has been well-trodden in the past 18 months or so, with Pedri and Gavi just two youngsters to quickly make the step up.

Inter made up for a dip in their determination and character with a resounding 5-0 win over Salernitana, according to Lautaro Martinez. 

A four-game winless run in Serie A and two wins in seven in the competition had seen Inter slip off top spot and fall two points behind leaders Napoli. 

However, the Nerazzurri returned to the summit on Friday after Martinez found the back of the net in a top-flight game for the first time since December. It ended a barren run of no goals in 425 minutes, making it his worst such spell in all competitions since going 430 minutes without a goal in January 2018.

The Argentina international ended the match at San Siro with a hat-trick, while strike partner Edin Dzeko scored the other two as Inter went a point clear at the summit ahead of Napoli's meeting with Milan on Sunday. 

Martinez was pleased to see Simone Inzaghi's side get back on track after a sluggish start to the year. 

"A win was missing and there were no goals for the team. Today we scored five and we are happy," Martinez told Sky Sport Italia. 

"I personally experienced a difficult moment because a striker lives to score goals. Today I was lucky enough to score three goals. 

"I went out on the pitch with a lot of desire and anger because it was an important match for us and an important period is approaching. 

"We had to demonstrate a lot of things because we have lost a bit of determination and character.  

"When I go to bed, I talk a lot with my wife because I'm sad when I can't help the team with goals. I talked a lot with her, with friends and my family. I dedicate these three goals to my daughter. 

"[Inzaghi] always gives me confidence. He fights with us from the sidelines."

Phil Mickelson will skip the Players Championship as his hiatus from golf continues. 

Six-time major champion Mickelson was a notable absentee from the 144-player field that features 48 of the top 50 in the world rankings. 

The 51-year-old said in February he was taking some time away from the sport following the backlash to his comments promoting a Saudi Arabia-backed Super Golf League. 

Mickelson had suggested that although Saudi Arabia has "a horrible record on human rights", the threat of the potential breakaway competition could be used to "reshape how the PGA Tour operates". He subsequently apologised for making "reckless" comments. 

While Mickelson has yet to set a date for his return to action, it will not come at TPC Sawgrass next week. 

Harris English, Steve Stricker and Tiger Woods were the only other qualified players not to commit to the competition. 

Jurgen Klopp hinted he could remain at Liverpool beyond 2024 if he has the energy required. 

Speaking ahead of Wednesday's FA Cup victory over Norwich City, Klopp said he was unsure whether he would extend his contract at Anfield. The German's deal is due to expire at the conclusion of the 2023-24 season. 

The 54-year-old has won five trophies – including Premier League and Champions League titles – during his six and a half years on Merseyside, and on Friday he said it was still his intention to see out his deal. 

However, he believes it is more important that the club is positioned to continue challenging for multiple honours even if he is no longer at the club. 

Asked what would convince him to continue at the helm, Klopp replied: "If I have the energy levels for it. That is important. I love what I do but I've said a couple of times there must be something else out there in the world, to be honest, apart from always thinking about properly skilled, good-looking, fantastically nice football players. 

"But I really don't think about it. At the moment I am full of energy but we have to – I have to – make sure that is the case because I don't want to sit around and be more tired than others and think: ‘Wow, why is everyone bothered about the things out there because I couldn't care less?' 

"My future will be OK. I don't have to plan. I could book last minute – let's put it like this. It is not a problem. No, the plan is the future of the club that we are constantly working on, that everything is in place and the things we do are not for me, not for us, not for this generation, they are for a long, long time. 

"So many things we've tried to improve over the years. It's about just doing the right things, employing the right people, putting them in the right positions. It doesn't mean you win the title, it just means you have the right people for the right job, so use them – and that's what we try. 

"These people – a lot of them are here at the moment – will be good and it will be fine whenever it will be after I leave. The plan at the moment is to do 2024, thank you very much." 

Liverpool will look to close the gap to reigning champions and Premier League leaders Manchester City to three points by defeating West Ham on Saturday. City are in action against local rivals Manchester United the following day.
