Both Lleyton Hewitt and Richard Gasquet used their media availability at the Davis Cup on Thursday to give their respect to Roger Federer after he announced his retirement on social media.

Federer, 41, won the first of his grand slams in 2003 at Wimbledon, and in that tournament it was Hewitt who was the reigning champion after becoming the youngest ever world number one back in 2001.

They came through in the same era, with Federer quickly overtaking the Australian as the sport's top attraction, and he would retain that mantle for over a decade as he and Rafael Nadal began their legendary rivalry.

Reflecting on their time on tour together, Hewitt called him "nearly unbeatable" as he shared his admiration.

"Yeah, he was from my kind of era, I guess," he said. "We were the same age, we grew up together in juniors. 

"I knew Roger extremely well and probably saw him slightly different to everyone else as well, because we grew up together. But he was the greatest of that time. 

"You know, obviously there are a couple of other guys now that are really putting their hand up, but he went clear easily from a grand slam perspective and really just his win-loss ratio [in the] mid-2000s era, he was nearly unbeatable. 

"It was pretty much only Rafa [Nadal] that could get him, especially on the clay. But most of all he's been a great ambassador for our sport. 

"I've always said that you don't want to push those guys out of the game too early. 

"Everyone wants to talk about retirement. When are they going to retire? You want to hold on to those greats. They've done so many special things for our sport. 

"But yeah, obviously, the body – you get to my age and his age now, and it's not easy. He's done everything in the sport that you could ever dream of."

In his own interview, Gasquet shared the sentiment, declaring "there is only one Roger Federer".

"It is a big shock – he is a legend of the game," he said. "It's not easy for anybody, I know it will be a big thing at the Laver Cup. I'm sure it will be wonderful there. 

"It's a tough loss for tennis. It will be different after that. It's still tennis, but it won't be the same without Federer.

"I was leading 1-0 against him [head-to-head], I won in Monte Carlo – but after that I lost maybe 20 times. I'm not the only one of course, it was incredible when I got to face him. 

"He is a legend of the game, everybody knows it. The technique, the charisma – everything was crazy. There is only one Roger Federer."

The greatest quarterback in NFL history took the opportunity on Thursday to pay his respect to fellow sporting icon Roger Federer after arguably the best player of his generation announced his retirement.

It is hard to imagine anyone will ever eclipse Brady's record seven Super Bowl wins, while Federer's mark of 20 grand slams will also likely stand the test of time as the new generation coming through share them around.

Brady, 45, is four years older than Federer, and gave retirement a go earlier this year before announcing his return 40 days later, so he knows exactly what kind of emotions Switzerland's greatest ever sportsman is going through.

When asked about his thoughts on Federer during Thursday's press conference, Brady shared his admiration.

"Phenomenal," he said. "Just a great player. He is just a great competitor and I think all those guys… we all work so hard. 

"We're all just working hard trying to be the best we can be at it, and he had a great run.

"He was great, always respectful of everybody and it meant a lot. He cared a lot. He maximised his opportunities. That's all we can all ask of ourselves."

Jose Mourinho admitted he was "a little scared" amid speculation of Nicolo Zaniolo leaving Roma, while he refuted suggestions the attacker was difficult to manage.

Zaniolo scored the winning goal as Roma ended a 14-year trophy drought, defeating Feyenoord in the inaugural Europa Conference League final in May.

But speculation persisted in the close season that the 23-year-old may depart the Eternal City, with Juventus reportedly the favourites to secure his signature.

Zaniolo dismissed the move as never likely ahead of Thursday's Europa League clash with HJK Helsinki, which Roma won 3-0 after goals from Paulo Dybala, Lorenzo Pellegrini and Andrea Belotti.

While the Italy international suggested a transfer was never on the cards, Mourinho acknowledged he was nervous he could lose one of his brightest prospects.

"The director [Tiago Pinto] never came to me to tell me: 'this possibility exists'. Never. You read so many things, especially in the summer," the Roma coach told reporters after victory over HJK. 

"I knew he was an important player for us, with different qualities than the others. He's the only one with this physical potential. Yes, I was a little scared.

"He's a good guy, they told me he was a disaster as a professional. Either it was lies or he changed. I have never seen him arrive late, never had problems."

Roma sit three points behind early pacesetters Real Betis in Group C, with Ludogorets in second after defeating the Giallorossi on matchday one.

Marion Bartoli says she feels "a sense of sadness" after Roger Federer announced his retirement from tennis, just weeks after Serena Williams' grand slam swansong.

Federer – a 20-time major champion – revealed on Thursday that he had made the "bittersweet decision" to end his glittering career, with next week's Laver Cup being his farewell tournament.

The announcement comes just over two weeks after Williams made her final slam appearance at the US Open, and 2017 Wimbledon champion Bartoli believes it represents "the end of an era" for the sport. 

When asked for her reaction, Bartoli told Stats Perform: "A sense of sadness, obviously, because we lost in the space of two weeks Serena [Williams] and Roger Federer who are basically two of the biggest stars that ever played the game, and two of the greatest who have ever played the game.

"I sense it was the end of an era almost because they have been part of my journey. When I was playing, Roger was obviously at his peak winning a lot of things and then Serena as well and now coming to see both of them taking their retirement almost at the same time.

"I feel like that book is almost closed, and now we are moving to the new generation of players with Carlos Alcaraz and all of them, but Novak [Djokovic] and Rafa [Nadal] are still hanging on.

"A sense of sadness obviously, but then completely understand his decision from what he had to face in the past three years."

Bartoli, who was also runner-up at the All England Club in 2007, thinks there are many players capable of challenging for the major titles in years to come.

Although, she does not see any player dominating tennis in the same manner as the 'Big Three' in Federer, Novak Djokovic and Rafael Nadal.

"I think our Alcaraz will very much be in the mix, but I don't think we will see one player being at 20 grand slams in 15 or 20 years, I don't believe it," she said.

"I think those three have been more than even superhuman. They've brought tennis to a level of consistency that, and along with Serena as well, I don't think anyone will be able to replicate that.

"When you see Carlos, he had an amazing US Open, just an incredible achievement. But Novak was not there, Rafa was injured, Roger doesn't play anymore, [Stefanos] Tsitsipas lost in the first round, [Alexander] Zverev can't play.

"It's just a lot of circumstances, and he had to save two match points against [Jannik] Sinner. So I don't see him dominating tennis as Roger did, or Novak did or Rafa did for the next 20 years, I just don't see it. 

"I think that the level between each other, it's very close. You don't see a major gap. So I think we'll have maybe Carlos winning one and then Sinner winning one, Zverev finally winning one and then Medvedev winning more.

"It's just going to keep rotating between maybe five or six names, but I don't think will be one name that keeps winning everything."

Maurizio Sarri bemoaned familiar "emotional breakdowns" and Ciro Immobile declared the result as "humiliating" after Lazio were thrashed 5-1 at Midtjylland in the Europa League on Thursday.

Sergej Milinkovic-Savic's 57th-minute strike proved a mere consolation as Lazio never recovered from going 3-0 down in 52 minutes after goals from Paulinho, Sory Kaba and Evander.

Gustav Isaksen and captain Erik Sviatchenko added further finishes following the Lazio midfielder's effort, condemning Sarri's side to a humbling defeat on their travels to the MCH Arena.

It marked just the fourth time Lazio have shipped five or more goals in a UEFA competition, leaving Sarri to question his methods as he lamented a reoccurrence of previous problems.

"I don't see great differences [from previous seasons]," Sarri told reporters. "These sudden emotional breakdowns are similar to those of previous years.

"It is difficult to understand the reasons: if it's me I have to take a step back, if it's the players it has to go away."

Lazio were met with jeers from their travelling supporters and Immobile acknowledged the boos were justified.

"The fans reacted with a clear head. They told us they were rightly p***** about what they saw. But to look forward, they told us not to give up and that nothing was lost," Immobile said.

"We thought we had taken a step more than last year, but we were wrong. Losing like this is really humiliating. I see it different from the defeats against Bologna and Verona.

"We played with little humility. In Europe, you pay for these things and we have paid enough for them – five goals are unacceptable."

Phil Mickelson says his name on the lawsuit against the PGA Tour is no longer necessary after the LIV Golf International Series joined its players as a plaintiff.

LIV Golf players accused the PGA Tour of benefiting from operating as a monopoly, while alleging the former tour had improperly suspended the defectors following their decision to join the breakaway league.

Abraham Ancer, Carlos Ortiz, Pat Perez and Jason Kokrak have already withdrawn their names from the lawsuit, with the lawsuit losing four of its 11 original plaintiffs.

Talor Gooch, Matt Jones and Hudson Swafford – three players still on the lawsuit – had sought a temporary order to allow them to compete in the PGA Tour's playoffs but were unsuccessful with their request.

Ian Poulter and Bryson DeChambeau are also among the high-profile names to sue, alongside Mickelson, who may step away from the lawsuit after LIV Golf became involved.

"I haven't done anything yet, but now that LIV is involved, it's not necessary for me to be a part of it," Mickelson said after playing at a LIV Golf warm-up event at Rich Harvest Farms on Thursday.

"I currently still am [part of the lawsuit]. I don't know what I'm really going to do. The only reason for me to stay in it is damages, which I don't really want or need anything.

"I do think that it's important that players have the right to be able to play when and where they want and when and where they've qualified for.

"Now that LIV is a part of [the lawsuit] that will be accomplished if and when they win."

The PGA Tour suspension will mean Mickelson, along with Dustin Johnson, Brooks Koepka and Patrick Reed cannot represent the United States in September's Presidents Cup.

Roger Federer ranks among sporting greats such as Michael Jordan, Tiger Woods and Tom Brady.

That was the message from 2013 Wimbledon champion Marion Bartoli, who hailed Federer after he announced his appearance at September's Laver Cup would be his last in professional sport.

The 41-year-old won 20 grand slam titles across a legendary 24-year career, only Novak Djokovic (21) and Rafael Nadal (22) can boast more major crowns in men's tennis.

Federer has also won more men's singles main draw matches in grand slam tournaments than any other player in the Open Era (369), leaving behind a magnificent legacy as he prepares to step away from the court.

Bartoli has experienced retirement herself, having called quits on her career after a failed comeback from injury in 2018, and asked by Stats Perform whether Federer was a GOAT – greatest of all-time – Bartoli said: "Yes, he is very much in there – absolutely.

"Michael Jordan, Kobe Bryant, LeBron James, Tiger Woods, Tom Brady, they are people that transcend their sports – they are icons.

"You go in the streets, you say Roger Federer. I'm in Dubai right now [and if] you say 'Roger Federer' everyone would know who he is. And the same for LeBron and Michael Jordan.

"When you transcend your sport and you become an icon and everyone knows who you are, that's when you know you have been one of the greatest of all time across every sport.

"Same for Serena [Williams], you can put Novak and Rafa in there as well. But it's just that amount of fame and that amount of inspiring [the next] generation."

Having spent 237 consecutive weeks ranked as number one, Federer holds the record for the longest such streak in men's singles history after a four-and-a-half-year spell at the summit.

Federer was also present in the top 10 of the men's singles rankings for 750 weeks, an unmatched number for a male player since the rankings were first published in 1973.

Regardless of Federer trailing Djokovic and Nadal for grand slam titles, Bartoli believes the Swiss remains the best of the trio due to his elegant playing style.

"It's very much depending on your own taste in a way. If you like beautiful, elegant, smooth tennis you have to go for Roger Federer," she added.

"Now obviously with Novak having 21 and Rafa having 22 grand slams, if we speak numbers only then you have two players on top of him.

"But I think it's very much a debate because it depends on the style of play you like and, that said, I absolutely love to see Novak play and win.

"I absolutely loved to see Rafa winning again at Roland Garros this year, I think it was one of the most incredible sports achievements that you can possibly witness.

"But in terms of game style, and the way he has revolutionised tennis, I think Roger was the first one. And then they pushed each other to new heights and I think that was really special to see."

While many youngsters look to emulate Federer, Djokovic and Nadal, Bartoli highlighted the importance of Pete Sampras and Andre Agassi, too.

"You can tell how much impact a player [has] when you see a new generation trying to copy your style. I think Pete Sampras had that impact as well as Andre Agassi on the generation of Roger, Rafa and Novak," she continued.

"Roger has had that impact on the new generation with Carlos Alcaraz. So that's why I say that he was really the first one to elevate the game to another level because he brought that dimension of his forehand when he was really almost able to play the ball wherever he wanted.

"I always remember that sentence from Andre Agassi, when he started to play against Roger saying, 'well, I never felt against anybody that I had to play on a 20-centimetre square because that's the only safe spot I can play, which is deep to Roger's back. If I play anywhere, he will take the game away from me'. [Federer] was the first one to [do that] and then obviously Rafa and Novak arrived and sought to change that and they pushed each other to new heights.

"When you have the pinnacle of the 2008 Wimbledon final and all those matches in between them that was just beyond epic for me."

Erik ten Hag is confident Cristiano Ronaldo will score more goals after the forward opened his account for the season to help Manchester United shoot down Sheriff in the Europa League.

Ronaldo had not started any of United's previous four Premier League matches and failed to impress in a home defeat to Real Sociedad last time out.

However, having started Thursday's game, Ronaldo was on target from the penalty spot as United got three points on the board in Group E.

It was the 699th club goal of Ronaldo's career, albeit his first in the Europa League, with Sheriff the 124th different side the 37-year-old has scored against, and Ten Hag is expecting plenty more to follow this season.

"He needed that goal," Ten Hag told United's club media. "He was close many times, but you always see he wanted that so much. We're happy for him, and the team wanted him to bring that goal. 

"We could expect this when you miss pre-season, he has to work really hard and invest to get the right fitness. He will score more goals. He's really close; when he gets more fitness, he will score more."

The United boss was also impressed by the performance of Jadon Sancho, who opened the scoring after 17 minutes when he turned on Christian Eriksen's pass and tucked a neat finish into the bottom-right corner.

Sancho, who was left out of Gareth Southgate's England squad earlier in the day, has now scored three goals in his last six appearances for United, as many as in his previous 24 games combined.

"I'm really pleased with [Sancho]," Ten Hag said. "[He scored] another goal, and he also scored many goals in pre-season.

"He's doing well, but I think there's much room for improvement for him because he has so many skills. So, bring it on the pitch and when he has that belief, I think he can be even more productive."

Meanwhile, Sancho underlined his determination to earn an England recall for the World Cup in Qatar later this year.

"It was really important that we got the win today," the winger told reporters. "Our last home against Real Sociedad was an upset and coming into this game, we knew we had to get the three points.

"Obviously, it is disappointing not to get the call-up, but I have to keep working hard and hopefully, I do get the call-up for the World Cup. I just have to focus on myself and carry on working hard."

United have won five of their last six games in all competitions, as many victories as they had registered in their previous 21 matches combined.

WTA world number one Iga Swiatek thanked Roger Federer for "everything you've done and everything you are for our sport" after the Swiss great announced his retirement.

Federer confirmed on Thursday that he would bring his illustrious playing career to a close after the Laver Cup.

The 41-year-old will bow out with 20 grand slam titles to his name, a feat bettered by only two male players – Rafael Nadal and Novak Djokovic.

Swiatek, meanwhile, won her third major title last week, defeating Ons Jabeur in straight sets to clinch the US Open, following her successes at Roland Garros in 2020 and earlier this year.

"I just want to thank you for everything you've done and everything you are for our sport," 21-year-old Swiatek tweeted in response to Federer's announcement.

"It's been a privilege to witness your career. I wish you all the best." 

Swiatek followed her post with a goat emoji, signifying that Federer is the greatest of all time.

Chris Evert, a former world number one, also joined the tributes to Federer, tweeting: "He was the epitome of a champion; class, grace, humility, beloved by everyone…and he elegantly mastered the sport like no other…Good luck to you, @rogerfederer don't go too far!"

Martina Navratilova, an 18-time major winner, posted: "What a heartfelt message, full of love, life, hope, passion and gratitude. Which is exactly how Roger played the game we love so much. Thank you thank you thank you, for all the magic!!!"

Real Betis veteran Joaquin marked his name in Europa League history after becoming the oldest scorer in the competition with a first-half strike against Ludogorets.

Manuel Pellegrini's side were ahead after 25 minutes on Thursday following Luiz Henrique's header from Juan Miranda's cross.

Captain Joaquin doubled Betis' advantage six minutes before the break, drifting in from the left to curl a wonderful effort into the top-right corner past Sergio Padt.

That strike made Joaquin, aged 41 years and 56 days old, the oldest player to score in the Europa League, surpassing Molde's Daniel Hestad after his goal against Celtic in November 2015.

Kiril Despodov pulled one back for Ludogorets before the break, though Betis restored their two-goal lead after Sergio Canales found the net in the 59th minute.

Ludogorets substitute Rick responded with 16 minutes remaining to tee up an enticing conclusion, but Betis held on for a 3-2 victory to remain as the early Group C pacesetters with two wins in as many games.

Emma Raducanu struggled with injury as she slumped out of the Slovenia Open in a second-round 7-5 0-6 6-3 loss to Anna-Lena Friedsam.

The 2021 US Open champion has faced an uphill battle on the WTA Tour this year and suffered another setback in Portoroz, where she was the top seed, playing the latter two sets with her left thigh strapped after a medical time-out.

A recovery looked possible when Raducanu cruised through a second-set bagel, yet the 19-year-old succumbed in the decider.

Raducanu's defeat follows a first-round exit at Flushing Meadows in a dismal attempt to defend her title.

Friedsman's win, meanwhile, secures the world number 213's first appearance in the quarter-finals of a Tour-level event since she lost in the final of the Lyon Open in 2020. It was also her second victory over Raducanu.

Diane Parry will face Friedsman in the last eight, after she overcame Anastasia Potapova, while Katerina Siniakova – who last week completed a career Grand Slam in doubles at the US Open – defeated Jodie Burrage.

Meanwhile, reigning champion Jasmine Paolini overcame a tie-break finale against Kaja Juvan. The Italian fought back to win 5-7 6-2 7-6 (7-5) to stay on course for a successful title defence.

At the Chennai Open, Anastasia Gasanova failed to back up her first-round win over top seed Alison Riske-Amritraj with another success, as Britain's Katie Swan edged her 7-6 (7-5) 6-2.

That sets up a quarter-final clash with qualifier Nao Hibino.

The top two seeds left in the competition, Magda Linette and Tatjana Maria, also progressed on Thursday.

Shane Lowry never considered joining the LIV Golf International Series due to his belief the breakaway league is "bad for the game", suggesting the "ridiculous" prize money throughout golf will alienate fans.

Lowry edged past Jon Rahm and Rory McIlroy to win the BMW PGA Championship last week, before labelling his victory "one for the good guys" amid the presence of LIV players at Wentworth.

While the 2019 Open winner criticised the Saudi Arabia-backed circuit in the build-up to that tournament, he attracted criticism earlier this year when he defended his decision to play the Saudi International by declaring; "I'm not a politician, I'm a golfer."

Lowry admitted he was wrong to make that remark, though his main objection to the existence of LIV Golf remains its decisive impact on the sport.

"When I said the 'I'm not a politician' remark, my first thought was 'why did I say that?' It was the wrong thing to say," he told the No Laying Up podcast.

"The thing is, I played the Saudi International for the last three years. So, for me, I would have been very hypocritical if I sat here and said, 'it's about where the money is coming from'.

"Will I go back and play the Saudi International next year? No. But I just think the LIV tour is bad for the game because it is very divisive.

"I am one of the players that thinks LIV should not exist. I don't like the idea of it.

"It is a tough subject for me to talk about because I have never been outspoken. The reason I hadn't is because no one had asked me about it. Rory is outspoken because every day he is in front of the media."

Lowry also believes the huge financial incentives available on every tour could turn fans away from golf, adding: "We are very lucky the corporate world loves golf and that's why we have such great sponsors and that's why we play for a lot of money.

"But I do feel like this is causing a division in the game and it's going to p*** people off.

"People are going to stop watching it. I think the amounts of money that are being thrown around are absolutely disgusting at the minute. I feel all people talk about is money now. 

"We play for points now in the FedEx Cup, but I watched the Tour Championship and all the commentators talked about was how much money they're going to win, and I thought, 'will you just talk about the trophy or the title or how many times Tiger [Woods] has won it?'

"The general Joe Soap, the guy who works his nuts off to make 50 grand a year and has to struggle to pay his membership at his golf club and loves the game so much, this probably p***** him off more than anyone."
