Value in the transfer market is always hard to gauge, but that feels especially true in the Premier League in this window.

Sadio Mane has left Liverpool for £35million, and Raheem Sterling is on his way out of Manchester City for £45m. Meanwhile, Southampton have reportedly asked for £75m for midfielder James Ward-Prowse.

That comparison is perhaps not fair on Ward-Prowse – Saints' most important figure – but it illustrates how erratic these fees can be.

It is slightly tricky then to establish who might be the most valuable Premier League player, yet why not have a go?

Inspired by Bill Simmons' NBA trade value list for The Ringer, ranking the 64 most valuable basketball stars, Stats Perform has put together an equivalent Premier League top 20.

Of course, there are key differences between how the markets work in the NBA and the Premier League, so a brief explainer is required before complaints come from fans of one or two clubs...

This is not a ranking of the 20 best Premier League players but rather the 20 most valuable – or 20 most difficult to sign.

The following factors have all been considered: how important these players are to their clubs, how replaceable they are, how proven they are, how likely they are to be sold now or in the near future, and how much they would cost if they were to move, influenced by ages and contract situations.

So, let's dive in...

1. Trent Alexander-Arnold – Liverpool

Alexander-Arnold is Liverpool's chief creator from right-back, unique in his passing ability and set-piece quality. The Reds will have an extremely tough time when they come to replace the England man; fortunately, that will not be any time soon, with the Anfield favourite a local boy, a Liverpool fan and under contract until 2025.

2. Phil Foden – Manchester City

Although perhaps still not quite the main man at Etihad Stadium, Foden is City's answer to Alexander-Arnold. Having waited so long to bring an elite talent through their academy, the champions will be in no rush to sell him – especially as Pep Guardiola is such a big fan.

3. Erling Haaland – Manchester City

If Alexander-Arnold and Foden are completely unattainable for rival clubs, there remains a possibility Haaland's stay at City could last only a few seasons, as Real Madrid and Barcelona are likely to again be interested soon enough. But City could command a huge fee for one of the most sought-after strikers in European football.

4. Kevin De Bruyne – Manchester City

It is perhaps no surprise City feature so prominently in this list, although there is a balance to consider. Their financial might means there is little motive to move on a star name, but they are also well placed to sign a replacement. Even at 31, there is nobody who could feasibly replace De Bruyne.

5. Virgil van Dijk – Liverpool

Replacing Van Dijk is a similarly tough ask. Liverpool are not afraid to cash in if it benefits the team, but it is difficult to imagine how losing their highly influential centre-back – undoubtedly the best in the Premier League – could ever be beneficial.

6. Mohamed Salah – Liverpool

Having seen Mane depart, Salah likely would not even have featured on this list had he not agreed a new contract. Now, though, both he and Liverpool are committed to one another for three more years. In the immediate future, Salah remains the Reds' leading man in attack.

7. Bruno Fernandes – Manchester United

It says a lot for the state of the United squad that Fernandes is the only Red Devil to be included. Cristiano Ronaldo is old, on a short-term contract and wants to leave, while Jadon Sancho and Marcus Rashford endured tough seasons. Fernandes ultimately did, too, but his quality is proven, and he will hope for an improved campaign under Erik ten Hag.

8. Son Heung-min – Tottenham

Spurs have a little more security now with Champions League football assured, surely able to keep Son happy – not that the outstanding forward ever appears too downcast. Son is now 30 but shows little sign of slowing after the best goalscoring season of his career.

9. Harry Kane – Tottenham

Son is just ahead of his strike partner on account of Kane pushing for a move last year. That was an unsuccessful bid, though, and City moved on with Haaland. Kane could perhaps be a candidate to replace Ronaldo, but again Tottenham have Champions League football while United do not.

10. Ederson – Manchester City

A move away from the division's elite attacking stars: Ederson simply could not be better suited for City's style of play, an outstanding goalkeeper with the passing range to fit into their midfield. A rival club surely would not even try to prise Ederson away.

11. Alisson – Liverpool

Liverpool do not rely on Alisson's ability with his feet in quite the same fashion, but there is very little between he and Ederson. Still just 29, the Brazil number one will keep his place between the posts at Anfield for the foreseeable future.

12. Reece James – Chelsea

The first Chelsea player on the list is James, who matches Alexander-Arnold for talent but might be seen as a more attainable transfer target for now. With the Blues still in the early stages of their new ownership, it is tough to tell exactly where they fit into the Premier League's hierarchy.

13. Mason Mount – Chelsea

As above, Chelsea would not have wanted to sell Mount under the previous regime and likely will stand firm again, but keeping players of his ilk relies on the club remaining as successful as they have been over the past 20 years.

14. Bukayo Saka – Arsenal

This Arsenal team is packed with young, hungry, talented players, few of whom their fans would like to see depart. But the Gunners have also long since been positioned as sellers to the elite clubs. Saka, the best of the bunch, could attract attention soon enough.

15. Bruno Guimaraes – Newcastle United

As with Chelsea, there is an element of the unknown around Newcastle. With big money and big ambitions, they could eventually join City in having the wealth and status to keep just about any player. Guimaraes – outstanding after talking up a Champions League title bid while still in the relegation zone – looks to be in for the long haul.

16. Declan Rice – West Ham

Rice might have more suitors than Guimaraes right now, but he might also be a more straightforward buy. Although David Moyes suggested £150m would be "the minimum" required to recruit Rice, a player of his talents will want to play in the Champions League – and the Hammers look to have missed their chance.

17. Darwin Nunez – Liverpool

Nunez could jump into the top three in a year's time, yet he still has only two seasons with Benfica on his CV and so will have to continue to prove his class in one of Europe's big five leagues before being ranked alongside Haaland.

18. Kai Havertz – Chelsea

Chelsea are already again having to rebuild the rest of their front line this year, so the future of Havertz appears secure. Despite netting the winning goal in the Champions League final a year ago, it feels like there is still more to come from the forward.

19. Ruben Dias – Manchester City

Besides those listed above, so many of City's outstanding players would be relatively easy to replace given their transfer budget and the pull of working with Guardiola. But the club have consistently lost leaders in recent seasons, so Dias is a key man for the coming years.

20. Cristian Romero – Tottenham

As long as Spurs are trying to keep Antonio Conte happy – and their business so far in this window suggests that is the case – Romero is unlikely to be going anywhere. The centre-back was superb after arriving at Tottenham Hotspur Stadium in January.

All eyes in the golfing world will be trained on St Andrews this week as The Open returns for its 150th championship.

The final major of a year of fracture for the sport will bring the biggest names together once more, but who is best placed to take home the Claret Jug?

Five Stats Perform writers have their say ahead of the tournament...

LIV AND LET LIVE? OOSTHUIZEN IS A ST ANDREWS MASTER – Pete Hanson

Is it time to live and let live (or rather LIV and let live)? The proverb is defined as being able to "tolerate the opinions and behaviour of others so that they will similarly tolerate your own", but in the instance of the LIV defectors it is increasingly difficult to accept the decision for jumping ship as anything other than a nauseating money grab. That being said, looking at this through a purely sporting lens, LIV players who have qualified for The Open are allowed to play this weekend and Louis Oosthuizen knows a thing or two about St Andrews. The South African romped to a seven-shot win at the home of golf in 2010 and only lost in a three-man play-off to Zach Johnson at the same venue five years later. He was also leading through three rounds at Royal St George's a year ago before a final round one over coupled with a Collin Morikawa masterclass saw him end up tied for third.

RORY WINNING POPULARITY CONTESTS AND NOW SEEKS ST ANDREWS SUCCESS – Ben Spratt

If the LIV breakaway has made villains of a number of star names, Rory McIlroy is the PGA Tour's hero. With news of each defector, McIlroy has stood firm in his opposition to the Saudi-backed series – all the while stringing together a superb run of form, finishing in the top 20 in each of his past seven entries and the top 10 in each of the first three majors of the year. Rory is a very real contender this week, and there could hardly be a more popular winner. He has unfinished business at St Andrews, too, having tied for third in 2010 and then missed the 2015 event – where he would have been the defending champion – through injury.

RED-HOT SCHAUFFELE IS THE MAN TO BEAT – Russell Greaves

Fresh from his victory at the Scottish Open – where other putative Open contenders floundered – Xander Schauffele is certainly one to watch. Last week's victory at the Renaissance Club, which came despite a two-over-par opening round, came hot on the heels of his triumph at the Travelers Championship, sending the Tokyo 2020 gold medallist to St Andrews as a man in form. The American has also been in the mix at golf's oldest major before, finishing tied second at Carnoustie in 2018, where a final-round 74 ended his hopes of a maiden major. That search will continue this week for the 28-year-old, with the Claret Jug firmly in his sights. 

MORE MORIKAWA MAGIC INCOMING? – Patric Ridge

Morikawa enjoyed a sensational 2021, triumphing at Royal St George's to claim his second major title aged just 24 and becoming the first player to win on his Open debut since 2003. Yet 2022 has so far failed to yield the same success for the defending champion. He went into the weekend with the lead at last month's U.S. Open, only for a wobble on the Saturday to prove costly. After recovering with a fourth-round 65 to finish tied for fifth, Morikawa said he had learned to "just go play golf", although that approach did not serve him particularly well at the Scottish Open, where he failed to make the cut. If he manages to find the composure that deserted him during that dismal third round in Boston, however, then the world number eight cannot be overlooked as a serious contender once again.

CANTLAY CAN COME GOOD ON THE MAJOR STAGE – John Skilbeck

As the rumour mill links him with an LIV Golf switch, Patrick Cantlay is keeping his focus on the course. The American had a win alongside Schauffele in the Zurich Classic of New Orleans in April and has achieved four top-fives and two top-15 finishes in his past seven events, including a tie for fourth at the Scottish Open. The elephant in the room is that Cantlay has mostly flunked the majors this year, tying for 39th at The Masters, missing the cut at the US PGA Championship and trailing home in a share of 14th at the U.S. Open. However, the 30-year-old is not fourth in the world rankings for nothing; his time is surely coming. Florida-based Cantlay ranks in the top five for birdie (or better) percentage on the PGA Tour when finding the fairway off the tee this year but is outside the top 70 when driving into the rough, so accuracy from the tee will likely determine his fate.

Chelsea have reportedly turned their attention to Bayern Munich winger and Germany international Serge Gnabry.

The decision was made to pivot away from Leeds United winger Raphinha after Barcelona seemingly moved into pole position for the Brazil international, with Chelsea then deciding to test the waters for former Arsenal forward Gnabry.

He is coming off his highest-scoring Bundesliga season, having netted 14 goals and contributed six assists in 34 league fixtures, scoring another three goals in the Champions League.

TOP STORY – CHELSEA GEAR UP FOR GNABRY BID

Despite it being widely reported that Chelsea have secured Raheem Sterling from Manchester City for fee of around £45million, the Blues are clearly not satisfied with their winger stocks. 

This was further fuelled by reports the club tried to include Christian Pulisic or Hakim Ziyech along with cash in a deal for Juventus centre-back Matthijs de Ligt, with Ziyech now appearing likely to land a move to Milan.

The Daily Mail claims Chelsea have enquired about Gnabry, 26, who debuted with Arsenal as a 17-year-old in 2012, but his time at the Gunners fizzled out with injuries before a loan move to West Brom, resulting in Werder Bremen scooping him up in a bargain £5m move.

He scored 11 goals in his first season in the Bundesliga to earn a move to Bayern, where he has tallied 171 games and 63 goals across four Bundesliga campaigns, winning four consecutive league titles.

ROUND-UP

– The Mirror is reporting that Barcelona's top priority is to sell Frenkie de Jong to fund their move for Leeds' Raphinha, while the Manchester Evening News claims top Manchester United officials are in Spain ironing out the details for the Dutch international's switch to Old Trafford.

– TalkSPORT claims that if United's chase of De Jong falls through, they are prepared to target Wolves midfielder Ruben Neves or Leicester City's Youri Tielemans.

– Wolves have rejected an offer worth over £20m from Everton for 22-year-old midfielder Morgan Gibbs-White, according to The Telegraph.

– According to the Irish Independent, 21-year-old Nathan Collins will become the most expensive Irish player ever when he completes his £20.3m move from Burnley to Wolves this week.

– Fabrizio Romano is reporting that Ousmane Dembele has decided to stay on at Barcelona, shunning interest from Paris Saint-Germain and Chelsea.

Jabari Smith Jr had his best Las Vegas Summer League performance on Monday, helping the Houston Rockets defeat the San Antonio Spurs 97-84.

After a pair of inefficient showings – going four-of-10 for his 10 points in the opener against the Orlando Magic and five-of-19 for 12 points against the Oklahoma City Thunder – Smith found his range against the Spurs.

He finished with 19 points, nine rebounds, two steals and one block as he displayed impressive defensive versatility, and he shot six-of-12 from the field, three-of-five from long range and four-of-five at the free throw line.

Smith, at six-foot-10 with a seven-foot-one wingspan, showed he can guard at least three positions, with only enormous centres and small, shifty point guards figuring to pose any threat to the smooth-moving wing.

He combined well at both ends with fellow first-round pick Tari Eason (17th selection) who shined with 22 points, 10 rebounds, three assists, two blocks and two steals, hitting nine-of-16 from the field and two of his three attempts from range.

Spurs first-round picks Malaki Branham (20th selection) and Blake Wesley (25th selection) also both showed strong two-way games.

Branham scored a team-high 20 points on eight-of-18 shooting, and while Wesley was much less accurate (three-of-20 from the field for 14 points), he got to the free throw line (eight-of-nine), and collected team-highs in assists (four) and steals (three).

Immediately following that game was Chet Holmgren and the Oklahoma City Thunder as they beat the Orlando Magic 84-81 hours after it was announced the Magic's top pick Paolo Banchero would not participate in any more Summer League action.

While the Magic believe they have seen all they needed from Banchero, the Thunder are using Summer League to build chemistry between their young core, with second-year point guard Josh Giddey also suiting up again.

Holmgren led his team in points with 16 on seven-of-10 shooting, and rebounds with 10, while blocking two shots and dishing two assists.

Giddey's goal of becoming a more efficient scorer is still a work-in-progress, finishing three-of-11 from the field for his 12 points, but his all-round game continues to blossom as he posted eight assists and seven rebounds.

In another notable stat-line, the seven-foot-five Tacko Fall came off the bench for the Utah Jazz against the Dallas Mavericks and collected an outrageous 15 rebounds in 17 minutes, with 13 of his rebounds coming on the offensive end. He also scored 12 points and blocked three shots.

New York Mets star pitcher Max Scherzer appeared back to his best in Monday's 4-1 win against the reigning champion Atlanta Braves in his second game back from injury.

Scherzer, who struck out 11 batters against the Cincinnati Reds last week in his return from six weeks on the sidelines, was a match-winner against the Braves, striking out nine while only allowing three hits and no walks in seven innings.

The Mets jumped out to a lead in the third inning through Pete Alonso's RBI double, before Alonso came around to score and make it 2-0 off Luis Guillorme's ground-out.

Those would be the only two runs from the first six innings, with Atlanta's one and only run coming from a solo homer in the seventh inning from Austin Riley as Scherzer approached 90 pitches, ultimately finishing his day with 93.

Guillorme drove home his second run in more emphatic fashion in the eighth inning, with his solo home run giving the Mets a 3-1 buffer, before Alonso collected an RBI ground-out in the last frame to seal the win.

Alonso's two RBIs give him a league-leading 72 for the season – six more than any other player – with Colorado Rockies first-baseman C.J. Cron and Cleveland Guardians third-baseman Jose Ramirez tied for second on 66.

With the win, the Mets move to 54-33 for the season, giving them the second-best record in the National League, three games behind the Los Angeles Dodgers.

Mikolas deals on the mound for Cardinals

The St Louis Cardinals came from some early adversity to comfortably defeat the Philadelphia Phillies 6-1 at home, with Miles Mikolas pitching a strong seven innings.

Mikolas' day started in bumpy fashion, giving up a first-inning home run to Rhys Hoskins, but the Phillies would score no more runs the rest of the way as Mikolas found his footing. He finished with seven-and-a-third innings pitched, giving up six hits and no walks while striking out five.

With the bat, Edmundo Sosa, Andrew Knizner and Corey Dickerson drove in a run each with three consecutive hits in the fifth inning, before Dickerson launched a two-run homer in the seventh and Lars Nootbaar completed the rout with a solo shot in the eighth.

Bobby Witt Jr makes history for Royals

Highly touted rookie Bobby Witt Jr had a spectacular day for the Kansas City Royals as they took both games of their double-header against the Detroit Tigers.

Witt went two-for-four at the plate in the Royals' 3-1 win in the first game, before going four-for-five with a double and a home run in his side's 7-3 victory later in the day.

He became the first player in MLB history to ever have at least six hits, three RBIs and three stolen bases in a double-header sweep.

The top pick from this year's NBA Draft, the Orlando Magic's Paolo Banchero, will not play in the remainder of the Las Vegas Summer League as head coach Jamahl Mosley feels he has seen enough.

Banchero, 19, debuted against the Houston Rockets last week and scored 17 points with six assists in the win, functioning as a six-foot-10 lead ball-handler and his team's de facto point guard.

He followed it up with 23 points, six rebounds, six assists, four steals and two blocks in an overtime victory against the Sacramento Kings.

Banchero was scheduled for a highly anticipated matchup with number two pick Chet Holmgren and the Oklahoma City Thunder on Tuesday night, but the organisation decided to pull the plug on his Summer League campaign and wrap him in cotton wool.

Speaking to the media about the decision, Mosley said he wants to use the rest of Summer League to evaluate the more fringe talent vying for a roster spot.

"I want to give these other guys an opportunity to play, to kind of be able to show what they're capable of doing," he said.

"That's the point of summer league, you know, give them a chance... an opportunity for these other guys to see what they're capable of doing. We've seen what Paolo was capable of doing.

"His understanding of what he needs to do in certain situations, the concepts that we're preaching offensively and defensively, he's grasping on to those.

"Watching film together, he's observing those things. He explains to me the things that he sees on the floor. 

"It's only two games, but you're watching those film sessions and you realise how he's registering all of it. So that's how you can make the judgement that it's time let these other guys get those moments.''

The Magic are also expected to withdraw R.J. Hampton and Admiral Schofield from the remainder of summer league, indicating they are locked into roster spots.

The Tampa Bay Rays’ quest for a wild-card spot in the American League took a hit Monday with the news that star shortstop Wander Franco will undergo surgery for a fractured hamate bone in his right hand that is expected to sideline him for five to eight weeks. 

The 21-year-old Franco sustained the injury during the first inning of Saturday’s game against the Cincinnati Reds after fouling off a pitch. He was placed on the 10-day injured list Sunday and will have the surgery on Tuesday. 

Franco made his major league debut in June 2021 and hit .288 with seven home runs and 39 RBIs in 70 regular-season games with the Rays. He then went 7 for 19 (.368) with a pair of homers and four RBIs in four games as Tampa Bay lost to the Boston Red Sox in the American League Division Series. 

Franco finished third in the American League Rookie of the Year voting, and the Rays signed him to an 11-year, $182million contract extension in late November. 

Franco, though, has been hampered by injuries in 2022, as he also spent nearly a month on the injured list with a strained right quadriceps before returning to the lineup on June 26. 

He has been limited to 58 games and is batting .260 with five home runs and 23 RBIs for the Rays, who entered Monday occupying the second wild-card spot in the American League. 

Pablo Carreno Busta bounced back from his Wimbledon disappointment to claim a straight-sets victory over Stan Wawrinka at the Swedish Open.

Carreno Busta was forced to pull out of his first-round clash with Dusan Lajovic at the All England Club because of a leg injury.

But back to fitness and back on the clay in Bastad, Carreno Busta – playing in only his sixth tour-level event since missing 13 months due to a foot problem – battled past Wawrinka 7-5 6-4.

The fifth seed said afterwards: "It was a very tough match for me in the first round. Against Stan it is always very difficult to start the tournament, so I'm happy because I thought my level was good.

"I played very solid from the baseline. It was a bit difficult with the wind, but I thought my serve was very good throughout the match. It was very important to my game."

Elsewhere in the draw, Laslo Djejre overcame Lorenzo Musetti in straight sets and home hope Elias Ymer beat Daniel Altmaier.

Jason Kubler reached the fourth round at Wimbledon and he continued his fine form on grass at the Hall of Fame Open by defeating Australian compatriot Jordan Thompson 6-2 6-3. Kubler will now face Felix Auger-Aliassime in the second round.

Steve Johnson enjoyed a run to the third round at SW19 and was victorious on home soil in Newport, the American beating countryman Stefan Kozlov, while Peter Gojowczyk defeated Ugo Humbert in straight sets.

There was more joy for home fans as Jack Sock eased to a 6-1 7-6 (7-2) win over Radu Albot. Sock will next play third seed Alexander Bublik for a place in the quarter-final.

The NBA board of governors is expected to vote this week to make the play-in tournament permanent going forward, as well as a rule change to eliminate the 'take foul' in transition.

Governors will meet on Tuesday with the expectation that the play-in tournament – which was first implemented in the 2020-21 season, giving two extra teams in each conference a chance at qualifying for the playoffs – is a near sure-thing to be adopted permanently.

According to ESPN's report, the feeling around the league is that the play-in tournament and flattened odds in the draft lottery – giving less incentive to finish with the worst record in the league – have gone a long way in curtailing the ugly 'tanking' generally seen in the final six weeks of a season.

The 'take foul' has been a hot topic over the past season as players routinely decided to intentionally foul a ball-handler to prevent a fast-break opportunity, limiting the amount of exciting break-away dunks and shows of athleticism in every game.

As is the case in European basketball and international FIBA rules, that play is expected to be reclassified as an unsportsmanlike foul, resulting in one free throw and possession remaining with the offensive team.

While those two changes are likely to go through without much opposition, another recurring topic from commissioner Adam Silver will be discussed: an in-season tournament.

Silver has been vocal over the past few years about his desire to have mid-season competition in the same vein as cup competitions in European football, giving the teams something else to compete for and to add excitement to the regular season.

It was initially going to be rolled out at the same time as the play-in tournament, but it was met with stiff resistance and put on the backburner.

Original discussions proposed a $1million prize to each member of the winning team, although ESPN's latest report says "the players would likely see more financial and competitive incentives before an agreement on the format might be reached".

Fabinho thinks Mohamed Salah could go on to be regarded as one of the greatest players to ever pull on a Liverpool jersey after signing a new contract.

Salah ended speculation around his future by agreeing a new three-year deal on July 1 – the Egypt forward only had 12 months remaining on his previous deal with the Reds and could have departed as a free agent after the 2022-23 season.

That would have been a significant blow for Liverpool considering Salah's impact since joining from Roma in 2017.

The 30-year-old has made 254 appearances for the Reds and scored 156 goals, assisting 58 more.

Those 156 goals rank Salah ninth on the list of Liverpool's record scorers, while his Premier League goal involvements tally of 164 is third only to Robert Lewandowski (184) and Lionel Messi (200) among players from Europe's big five leagues since August 2017.

He has played a vital role in Liverpool winning six trophies since his arrival, including the Reds' first Premier League crown and a Champions League title, but Fabinho is convinced there could be even more to come from Salah.

Speaking in Bangkok on Monday ahead of Tuesday's friendly against Manchester United, Fabinho said: "We are really happy for [Salah], happy to see him playing for Liverpool.

"He's already a Liverpool legend, but I think he can be one of the best Liverpool players in the history of this club.

"So I'm happy for him, for sure he will continue to score goals and play his best football because he is really important for us."

While pre-season friendlies might be considered of little importance to the average supporter, Harvey Elliott is fully aware of how crucial they could be to him.

The 19-year-old enjoyed an impressive loan spell with Blackburn Rovers in the Championship in 2020-21 and looked set for a prominent role in the first team upon his return.

But a dislocated ankle suffered against Leeds United in September kept Elliott out until February, and while he was able to take part in the final three months of the season, he freely admits he was not himself.

The England Under-21 international's mental state has improved over the off-season, however, and he is eager to make the most of pre-season.

He said: "It's easy to sort of get overwhelmed by the injury and come back, and you keep thinking about it and not feel comfortable and confident and stuff like that, and I think towards the end of the season, I did a little bit, because my form wasn't really there, and I wasn't really myself in training sessions just because I was a bit worried.

"So, I mean, now I feel 100 per cent, that the line has gone through last season. This season is a new one, new achievements to be reached and new goals to be reached as well.

"So I'm just looking forward to it and making sure, as I said, I'm in the best possible position to go out.

"I'll put myself out there to the manager, to the coaching team, to the players that, I'm still here, and I'm still able to play for the team. I'm still able to give my 100 per cent focus and committing to the team."

Here today, gone tomorrow – or is it tomato?

It's the end of an era in Pittsburgh, as the Steelers announced on Monday their longtime stadium will no longer be called Heinz Field. 

The Steelers will now play in Acrisure Stadium after reaching a 15-year sponsorship deal with the financial tech company. Financial terms were not released. 

"We are excited to partner with Acrisure for the naming rights to our stadium," Steelers President Art Rooney II said. "Acrisure provided us with an opportunity to ensure our stadium continues to be a valuable asset for our fans as well as keeping up with the market value of NFL stadiums."

The name change will take place immediately at the 68,400-seat venue, which had been known as Heinz Field since it opened in 2001. 

In their 21 seasons since its opening, the Steelers have won two Super Bowls, 10 division titles and made the playoffs 14 times. In this span, only the New England Patriots (80.5) and Green Bay Packers (73.8) have achieved a higher home winning percentage than Pittsburgh's 72.8 (122-45-2). 

Jack Wilshere has returned to former club Arsenal after being appointed their new under-18s head coach.

Ex-England international Wilshere announced his retirement at the age of 30 last week, having most recently played for Danish Superliga club AGF.

Wilshere graduated from Arsenal's academy and was regarded as one of the most promising players in world football at the time of his breakthrough.

He made his Premier League debut at the age of 16 years and 256 days in September 2008, which made him Arsenal's youngest league debutant.

Following an encouraging loan spell at Bolton Wanderers, Wilshere cemented his place in the Arsenal team during the 2010-11 campaign, making 35 top-flight appearances.

But the talented central midfielder went on to be plagued by injuries. After the 2010-11 season, he never managed to make more than 25 Premier League appearances in a single campaign again for the Gunners.

Stints with Bournemouth and West Ham followed, but again Wilshere struggled to stay fit, and he ultimately called it quits last week.

But having spent some time helping coach in the Arsenal academy while looking for a club last season, Wilshere has quickly set out on a new adventure by securing his first role in management back where it all began.

"It's a huge honour to have this role," he said. "It's no secret that I love this club. I love what we stand for and a big part of my life was spent in this academy, some of the best days of my life.

"This is a big opportunity for me, and I'm ready. I'm hungry and can't wait to help these young players thrive and be the best they can be on and off the pitch.

"It's a special feeling to be part of the Arsenal family. It never left me, and even though I moved on for a few years, my heart was always still at Arsenal.

"I can't wait to get started and help these young players thrive with a great team around me."

Elena-Gabriela Ruse was the only seeded player to fall in the opening round of the Hungarian Grand Prix on Monday, going down in three sets to Kamilla Rakhimova.

The seventh seed made numerous errors and was undone against Russia's world number 107 Rakhimova, who hit 23 winners en route to a 6-4 5-7 6-3 victory in Budapest.

Rakhimova will now face Ukraine's Lesia Tsurenko, who beat Carolina Alves 6-4 6-1 to reach the last 16.

At the Ladies Open Lausanne, meanwhile, another seventh seed in Tamara Zidansek was eliminated at the first hurdle by Anna Kalinskaya with a 7-6 (7-2) 3-6 6-3 defeat.

Sara Sorribes Tormo, the only other seeded player in action on day one in Switzerland, had far less trouble in seeing off Lauren Davis 6-2 7-6 (7-1).
