Borussia Dortmund striker Sebastien Haller has withdrawn from their pre-season camp in Switzerland after discovering a tumour, the club has confirmed.

The Ivory Coast international, who signed for the Black and Yellow on a four-year deal earlier this month from Ajax, has returned to Germany for further tests.

The Bundesliga outfit asked for the privacy of the 28-year-old and his family to be respected, adding they would provide further updates when possible.

Haller initially complained of feeling unwell after a training session on Monday, before subsequent medical examinations discovered a tumour on his testicle.

"This news today came as a shock to Sebastien Haller and to all of us," sporting director Sebastian Kehl stated.

"The entire BVB family wishes Sebastien a full recovery as soon as possible and that we can hug him again soon. We will do everything in our power to ensure that he receives the best possible treatment."

Haller's move to Dortmund marks his second Bundesliga spell, after previously playing for Eintracht Frankfurt, and comes on the back of an impressive resurgence at Ajax following a lacklustre period with West Ham.

The forward finished last season as the Eredivisie's top scorer, with 21 goals in 31 games.

Barbora Krejcikova beat Suzan Lamens in the opening round of the Hamburg European Open for her first victory on clay in over a year.

The third seed, who claimed a second Wimbledon women's double title this month, saw off qualifier Lamens 6-2 6-4 to reach the last 16.

Her most recent victory on a clay-court surface prior to Monday came at last year's French Open, winning both the singles and women's doubles titles at Roland Garros in 2021.

Last year's runner-up Andrea Petkovic is also through thanks to a 6-3 6-3 victory over Tamara Korpatsch and will now face Misaki Doi, who defeated Oksana Selekhmeteva.

At the Palermo Ladies Open, meanwhile, fourth seed Sara Sorribes Tormo battled back from a set down to overcome Ana Bogdan 2-6 6-4 6-2.

Third seed Zhang Shuai also avoided an upset as she secured a 7-6 (7-3) 7-6 (9-7) victory over Rebeka Masarova, while Irina Begu required three sets to beat Marina Bassols.

Erik ten Hag has warned Harry Maguire he must prove he is good enough to merit a regular spot in the heart of Manchester United's defence.

Maguire endured a difficult campaign both on and off the field last season, leading to suggestions David de Gea or Cristiano Ronaldo would take over as United captain.

However, Ten Hag clarified at a news conference during United's pre-season tour of Thailand and Australia that the England international will continue to wear the armband.

That was considered a huge vote of confidence for Maguire, though he now faces additional competition for a starting place with Lisandro Martinez on his way from Ajax.

United have reached a £56.5million (€67m) agreement with the Eredivisie champions for Martinez, who can play in a number of positions but favours playing as a left-sided centre-back.

That would naturally see him play alongside Raphael Varane, with Victor Lindelof also battling for a spot at the back.

While Ten Hag has reiterated he is a fan of Maguire's, the Dutchman is not offering his skipper any assurances heading into the new campaign.

"We have good centre-halves and Harry is one of them. He can play on the left side and on the right," Ten Hag told The Athletic.

"I think he is [a first-choice player]. He's proved it in the past but he also has to prove it in the present time and in the future. 

"He has played 46 times for England. Harry is really impressive and I expect a lot from him.

"But there is also internal competition and that is what a club like Man United needs. You cannot win with 11 players. We need a squad. 

"Especially this season with so many games. We have the Europa League, the Premier League and the World Cup, so we need a full squad with high-quality players."

Maguire is about to begin his fourth season as a United player after joining from Leicester City in an £80m transfer in 2019, making him the world's most expensive defender.

The 29-year-old has made 144 appearances for United, which is 11 more than next-highest Marcus Rashford during his time at Old Trafford.

However, he started only 75.5 per cent of games in all competitions last season, compared to 85.2 per cent the previous campaign and 90.2 in the 2019-20 season.

Asked about his decision to continue with Maguire as captain, Ten Hag said: "I always see the captaincy as an issue that I dictate. 

"The team building for me is an important point and I always talk about a group of leaders. The captain is a really important one and I'm happy with him.

"It can help [give him more confidence]. I will support him everywhere I can. In the end, he has to do it by himself, and he has the qualities to do it."

Maguire was not the only United player who struggled last season, with the Red Devils recording their lowest-ever Premier League points tally (58) and finishing in sixth.

United have won their opening two pre-season friendlies under Ten Hag, against Liverpool and Melbourne Victory, and the new boss is eager to restore his players' confidence.

"You can see that it affects the players. Now we have to cheer them up and motivate them," he said. "We are trying to bring the confidence back. 

"That's one of the important points to get success, that you have self-belief as an individual and as a team. That is a process, individual talks for instance, the positive approach. 

"Sometimes also you can be highly demanding because that is what we expect and we give them feedback. If they don't, you ask: 'Why are you not acting to your standards?'. 

"I want to get the maximum out of the players who are here. I think it belongs to Manchester that you're always looking for better, for competition, because that is a tool to lift, too."

After taking a shot at Russell Westbrook by using him as the butt of a joke, San Antonio Spurs rookie Jeremy Sochan took to Twitter to say he was "not intending on being disrespectful" to the Los Angeles Lakers superstar. 

In a social media video, Sochan and fellow Spurs rookie Malaki Branham participated in a word association game while at this month's NBA Summer League in Las Vegas. 

Branham gave the hint, "Russell Westbrook get 'em a lot", with the hope Sochan would guess "triple-double" in response.

However, Sochan immediately said "bricks".

The 19-year-old eventually correctly guessed "triple-double" and apologised for the insult on Twitter. 

"It's banter, I was not intending on being disrespectful," he said. "Heat of the moment, I was playing a game baby."

Sochan, the ninth overall pick of this year's draft, later went on to say Westbrook has "been one idol since I started watching the NBA and my dog is called Russell".

While Westbrook is the NBA all-time leader in triple-doubles with 194, the 2016-17 league MVP struggled mightily with his shot from 3-point range last season, shooting 29.8 per cent from beyond the arc. 

Among the 142 players with at least 250 3-point attempts in 2021-22, Westbrook had the fourth-worst shooting percentage.

Alejandro Davidovich Fokina sprung a surprise in the first round of the Hamburg European Open as he knocked out fifth seed Botic van de Zandschulp.

Van de Zandschulp reached the round of 16 at Wimbledon before losing Rafael Nadal, and he was undone by another Spaniard on the clay in Germany.

Davidovich Fokina broke Van de Zandschulp's serve six times en route to a 6-4 6-4 victory.

He will next face qualifier Jozef Kovalik, who also progressed on Monday alongside Slovakian compatriot Alex Molcan.

Lorenzo Musetti prevailed in three sets against Dusan Lajovic, while Karen Khachanov went the distance in beating Jan-Lennard Struff.

There was a shock at the Swiss Open Gstaad as home wild card Alexander Ritschard knocked out eighth seed Joao Sousa in straight sets.

Fifth seed Pedro Martinez beat fellow Spaniard Carlos Taberner, while there were also wins for Federico Delbonis and Jiri Lehecka.

Erik ten Hag has reiterated that Cristiano Ronaldo "is not for sale" and has suggested the forward may stay at Manchester United beyond the end of the coming season.

The Portugal international has been strongly linked with a move away from Old Trafford this transfer window, less than 12 months after returning to the club from Juventus.

Ronaldo scored 18 Premier League goals last season – only Mohamed Salah and Son Heung-min (both 23) scored more – but United still finished down in sixth.

He is said to be eager to join a team competing in the Champions League and has yet to return to pre-season training, which United have put down to compassionate leave.

Despite the ongoing speculation surrounding Ronaldo's future, Ten Hag has again made clear he is staying put for at least another year.

"It is clear – he is not for sale," Ten Hag told reporters on United's pre-season tour of Australia. "I planned with having him and I am looking forward to working with him.

"I am well-informed he also has an option [for a further season]."

Asked if that could mean Ronaldo remaining at United for the 2023-24 campaign, Ten Hag said: "Yes. I have signed here for three years, but in football it’s short-term as well. 

"We have to win from the start. So I don't look that far ahead."

As well as missing the first week of training at Carrington, Ronaldo has played no part in United's tour games in Thailand and Australia.

Ten Hag is not sure when Ronaldo will resume training, but he has not ruled out selecting him for United's Premier League opener against Brighton and Hove Albion on August 7.

"He is training," the Dutchman said. "I think we all know Ronaldo is a top professional and he will be fit [for the start of the season], so that is the last concern I have."

Ronaldo scored 24 goals in all competitions for United in his first season back at the club, which is 14 more than next-best Bruno Fernandes. No other United player reached double figures.

Concerns have been raised over Ronaldo's ability to adapt to Ten Hag's pressing style, however, which was evident under interim boss Ralf Rangnick last season.

"I think Cristiano is capable of doing that," Ten Hag said. "In his career he has shown everything.

"I have set my demand. We want to play in a certain way. A top player can contribute and Ronaldo is an absolute top player in our squad.

"The players dictate the way you play. Especially players who score goals because they are extremely important for a team. You construct your team around them."

Nasser Hussain says Ben Stokes' one-day international retirement came as a "massive surprise" but is understandable due an "absolutely crazy" schedule.

Stokes has announced he will bow out from the 50-over format on his home ground The Riverside on Tuesday, when England start a three-match series against South Africa.

The news came on the back of Stokes announcing he would sit out the T20s versus with Proteas and The Hundred with Northern Superchargers, following a dream start to his Test captaincy.

It follows ex-skipper Eoin Morgan's decision to retire from the international game, and leaves successor Jos Buttler and head coach Matthew Mott with another conundrum in the world champions' middle order.

Stokes said playing all three formats for his country was "unsustainable" for him and although former England skipper Hussain was taken aback by his announcement, he can understand it. 

"It came as a surprise, to be honest," he wrote in his Sky Sports column. "To completely knock 50-over cricket on the head is a massive surprise.

"You thought he would be looked after, in terms of being rested from various white-ball tournaments and formats - he'd already announced he was going to miss white-ball series', and The Hundred. 

"I guess it's the schedule. The cricketing schedule is absolutely crazy at the moment. If you just play in the one format - say Test matches - it's absolutely fine.

"But if you're a multi-format, multi-dimensional player, and even a Test match captain like Stokes, who throws himself into his job 100 per cent on and off the field, eventually something's going to have to give.

"For Ben, it is 50-over cricket, which is a real shame because he gave us and England fans their greatest day for a very long time in 2019, a day we'll never forget with that World Cup final win.

"He's a very bright, smart cricketer, he's a winner and he's a fighter."

James Harden made it clear this offseason that at this point in his career he cares more about having an opportunity to win an NBA championship than money. 

While his deal with the Philadelphia 76ers has yet to be finalised, Harden is expected to sign a two-year contract that will pay him $32million next season and includes a player option for 2023-24. That $32m salary is a steep discount after he declined his $47.4m player option for 2022-23. 

"I had conversations with [76ers president of basketball operation Daryl Morey], and it was explained how we could get better and what the market value was for certain players," Harden told Yahoo Sports. "I told Daryl to improve the roster, sign who we needed to sign and give me whatever is left over. 

"This is how bad I want to win. I want to compete for a championship. That's all that matters to me at this stage. I'm willing to take less to put us in position to accomplish that." 

The 32-year-old Harden has racked up plenty of personal accolades – NBA MVP, 10-time All-Star, three-time league scoring champion and NBA Sixth Man of the Year, to name a few. However, he has never won a title and only reached the NBA Finals once, in 2012 with the Oklahoma City Thunder. 

Following that NBA Finals appearance, Harden was traded to the Houston Rockets and became a superstar in the league. He was then dealt to the Brooklyn Nets in January 2021 to play alongside Kevin Durant and Kyrie Irving, but that experiment failed, and Harden was sent to Philadelphia last February. 

Harden averaged 21 points, 10.5 assists and 7.1 rebounds in 21 games after joining the 76ers. He then put up 18.6 points, 8.6 assists and 5.7 rebounds per game in the playoffs, where the 76ers lost to the Miami Heat in the Eastern Conference semifinals. 

Harden wound up appearing in 65 regular-season games overall in 2021-22, mostly due to hamstring issues. He averaged 22 points, 10.3 assists and 7.7 rebounds in those 65 contests. 

"I don't really listen to what people are saying. I wasn't right last season and I still almost averaged a triple-double," Harden said. "If anybody else had those numbers, we'd be talking about them getting the max. 

"People were used to seeing me averaging 40, 30 points, and so they viewed it as a down year. I was in Philadelphia for a couple of months and I had to learn on the fly. That's just what it was. I'm in a good space physically and mentally right now, and I'm just looking forward to next season."

With a full season ahead of playing alongside perennial NBA MVP contender Joel Embiid, and with the additions of P.J. Tucker and Danuel House (thanks in part to Harden's paycut), the 76ers are expected to be a favourite in the East. They also added De'Anthony Melton in a trade with the Memphis Grizzlies. 

"I think we have a much deeper team," Harden said. "That's something we wanted to address. If you look at our team now, we're positioned to go a lot further. I like how we stack up with the rest of the top teams."

With the end of one transfer saga comes the start of another. 

Robert Lewandowski has secured a long-awaited move to Barcelona, fulfilling a "dream" in the process and leaving Bayern Munich in the market for a new striker to lead their line.

But just how do you go about finding a like-for-like replacement for the most prolific marksman anywhere in the world?

One suggestion is that Bayern will make do with what they have, with Sadio Mane – a wide forward rather than a striker – having already been recruited from Liverpool this window.

While that may work, there are other potential options out there for Bayern to consider ahead of their latest title defence as they aim to win the Bundesliga for an 11th time in a row.

Here, Stats Perform takes a closer look at exactly what the Bavarian giants are losing in Lewandowski, and where they could go next.

LEWY LEADS THE WAY

Labelling Lewandowski as the best striker in European football is not hyperbolic when assessing the cold hard facts. 

The Poland international is coming off the back of a campaign that saw him register 50 goals in 46 games in all competitions, which is six goals more than the next-best Karim Benzema among players from Europe's top five leagues.

It is not like Lewandowski's output levels were dropping, either. The 35 league goals he registered last season are second only to the record-breaking 41 netted in the 2020-21 campaign across his 12 seasons in the German top flight with Borussia Dortmund and then Bayern.

Indeed, he has finished as the league's top scorer in each of the past five seasons, scoring 161 goals across that period, with no other player managing such a long streak in the competition's history. 

BEST OF THE REST

Put simply, Bayern surely cannot match those numbers with one player alone. If it is a pure goalscorer the German champions are after to fill the void, the aforementioned Benzema would be their best bet, the Real Madrid striker having scored 44 goals in 46 games last time out.

Persuading Madrid to let go of their focal point in attack would be nigh-on impossible, of course, likewise with Kylian Mbappe – Europe's third most prolific player in the 2021-22 season (39 goals in 46 games) – at Paris Saint-Germain.

Next on that particular list is RB Leipzig's highly-rated talent Cristopher Nkunku, who scored 35 goals in 52 matches last season and also chipped in with 16 assists. When purely weighing up goal involvements, Nkunku was only five short of Lewandowski last season, in a team with far less quality.

Indeed, Nkunku's 35 strikes last season came from an expected goals (xG) value of 28.23, meaning that he found the net 6.77 times more than he should have judging by the quality of the chances. Only Benzema (9.9) can better than across Europe's top five leagues.

Nkunku is not strictly a number nine, though, and his arrival – even if Bayern could tempt Leipzig into selling – would mean Julian Nagelsmann having to adapt his system in the final third of the field.

FORGET KANE... GO FOR KALAJDZIC

The likes of Timo Werner, Patrick Schick and Harry Kane are other names to have been touted as possible replacements for Lewandowski. Kane in particular would suit Bayern's system, and Bayern CEO Oliver Kahn admitted last week it would be a "dream" signing – while at the same time completely dismissing a move for wantaway Manchester United forward Cristiano Ronaldo.

With another couple of years to run on Kane's contract, however, and Tottenham demanding a nine-figure sum from Manchester City this time last year, the Bavarians would have to spend big to bring in the England international.

For a club that has only once spent in excess of €40m on an attacking player – Leroy Sane from Manchester City two years ago – and having already splashed the cash to bring in Mane from Liverpool, that seems unlikely to happen.

There is more than goals alone to judging just how good a striker is, of course, and some players are certainly more attainable than others. Look no further than Sasa Kalajdzic, who boasts a number of qualities suited to Nagelsmann, not least his presence in the box.

At six foot and seven inches, Kalajdzic is one of the tallest players around and knows how to put that to good use, with exactly half of his 22 Bundesliga goals coming via his head.

Despite playing just 22 top-flight matches since his Stuttgart debut at the end of the 2019-20 season, those 11 headed goals are bettered only by Andre Silva (12) and – him again – Lewandowski (13), who have played 45 and 83 games in that period respectively.

Kalajdzic may have missed most of last season through injury, but six goals in 15 games for a side involved in a relegation scrap suggests he is a player with plenty of potential and, just as importantly, likely to be gettable, as Stuttgart director Sven Mislintat recently admitted given the 25-year-old is out of contract next year.

MANE AND GNABRY TO STEP UP?

Away from the dream options and outside picks to take over from Lewandowski, Kahn himself said last week that in Mane his side already have a ready-made replacement.

Position wise that is not technically true, of course, but there is no doubt that Mane's goals return across his six seasons with Liverpool was mightily impressive.

With 120 goals in all competitions for Liverpool, he averaged a goal every 189 minutes – exactly one every two matches. Mane also assisted 37 goals, meaning he was directly involved in a goal every 137 minutes. 

In the Premier League, only Kane (134), former team-mate Mohamed Salah (118) and Leicester City's Jamie Vardy (104) scored more goals than Mane (90) over the course of his Liverpool career.

Unlike with Liverpool's front three, Bayern have been used to having one focal point up top in Lewandowski.

Serge Gnabry, who recently signed a contract extension at the Allianz Arena, can also play through the middle if called upon, and has done so to good effect for the Germany national side.

If reports from the German media are to be believed, that is the route Nagelsmann will have to go down for the 2022-23 season until a big-name number nine can be recruited further down the line.

Whether it will work will be intriguing to see, with the only certainty in all this being that Bayern can no longer turn to go-to man Lewandowski in their time of need.

Milan midfielder Tiemoue Bakayoko was stopped by officers and held at gunpoint earlier this month in what police have described as "a misunderstanding".

The Frenchman was halted by armed officers on July 3 and video footage showed him being searched.

The club officially have refused to comment on the matter, but did confirm that it was the 27-year-old captured on video.

A statement from Milan Police released to the outlet CNN on Monday confirmed that they had stopped the wrong man, while stressing their actions were legal and that Bakayoko had not sought to take any action.

"With reference to the video released today, related to a police check carried out against the Milan player Tiemoue Bakayoko, we underline that the check -- occurred during an operation whose context justified the adoption of the highest security measures, also for self-protection purposes -- was carried out in a manner that was absolutely consistent with the situation of danger," a police statement said.

"Once the person was identified and his being unrelated to the facts had been clarified, the police duties resumed regularly, without any kind of complaint on behalf of the person involved.

"It was a misunderstanding, but colleagues behaved correctly."

Bakayoko is beginning the second year of a two-season loan spell at San Siro from Chelsea.

Leon Goretzka will miss Bayern Munich's pre-season tour of the United States after undergoing surgery on his troublesome knee injury.

The Germany international only managed 19 Bundesliga appearances in the 2021-22 season after battling an issue with his left knee.

Goretzka has subsequently gone under the knife on Monday, ruling him out of clashes with D.C. United and Manchester City before the DFL-Supercup final against RB Leipzig on July 30.

Reports suggest the 27-year-old could be out for up to two months, leaving Julian Nagelsmann short of midfield options for the early part of the 2022-23 Bundesliga season.

Goretzka would likely have partnered Joshua Kimmich in midfield, with Marcel Sabitzer or new arrival from Ajax Ryan Gravenberch among the potential replacements for the Bundesliga champions.

Bayern may look to push through on their reported interest for Leipzig's Konrad Laimer as another option in midfield, as they prepare for the campaign without Robert Lewandowski, who is set to join Barcelona.

Tyson Fury has vowed to return to face the winner of the Oleksandr Usyk and Anthony Joshua bout, promising to fight his fellow Brit for free if he beats the Ukrainian.

Fury delivered a brutal sixth-round knockout of Dillian Whyte at a packed Wembley Stadium to retain his WBC heavyweight title back in April.

Either side of the all-British fight, Fury repeatedly stated his desire to retire and maintained his career was over after remaining unbeaten in 33 fights.

The 33-year-old has since reiterated he is "very happy" out of the ring after the WBC stated it wanted clarity over the world heavyweight champion's future.

But Fury has backtracked on his initial standpoint, suggesting he would face the winner of Usyk and Joshua's September 21 rematch in a unification bout for the right price.

Asked on talkSPORT whether the reports were true he had offered to train Joshua before his clash with Usyk in Saudi Arabia, Fury responded: "I'd train him to beat Usyk very easy, but he doesn't want my help because I would definitely train him to win and he obviously doesn't wanna win.

"I wouldn't tell you [the game plan] because that's giving the secrets away. But probably you'll see what I'll do.

"Because when this little middleweight batters the bodybuilder again, he's gonna lose again, then they're gonna call for Achilles to come out. They will call and groan for Achilles to come back.

"And I'm gonna say, 'Get f***ed, I'm retired, I don't wanna fight'. And then, when they're begging me to come out of retirement, I will return, but it's gonna be very costly like I said.

"I'll show you how to deal with a middleweight!"

While Fury referenced a significant payday to entice him to fight Usyk, he claimed he would face Joshua on for free at Wembley should he win the bout against the Ukrainian.

"Anthony Joshua's a s***house and I'll knock him out," Fury added. "If he beats Usyk, he's gotta fight me for free in England, for the fans.

"Not for hundreds of millions abroad in a foreign country, here, in the UK. Free-to-air TV, free tickets, sell out Wembley. It'll be watched by 30 million people for free.

"No pay-per-view. No money earned. We do this one for the fans of the UK. Let's see who's the real man of the people.

"I know I am, that's why I'm willing to do it for free in the UK, but he will not wanna do that, he'll wanna travel abroad because he's a businessman and I don't give a f*** about business."
