Paris Saint-Germain have once again rocked the world of sport after they confirmed the signing of Lionel Messi.

As bizarre as that may look written down, the deal is complete with the Argentina forward signing a two-year deal following his Barcelona departure.

Barca announced last Thursday that their dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions after his previous contract expired in June. He had spent his entire career at Camp Nou.

But the Parc des Princes now beckons and he will form probably the most-feared front three in world football alongside Kylian Mbappe and his old friend Neymar.

It's with the Brazilian where Stats Perform starts in this look at a selection of other sporting deals that shocked the world.

Neymar: Barcelona to Paris Saint-Germain, 2017

The Brazilian had formed a potent attacking trio with Messi and Luis Suarez at Camp Nou but a move to PSG was inevitable when the French side met his world-record buyout clause of €222million. He has played an important role in their continued dominance of French domestic football but has so far been unable to guide them to Champions League glory. He was reduced to tears by his side's 1-0 defeat to Bayern Munich in the 2020 final and then failed to inspire the team in the 2021 semis as Manchester City knocked them out. But maybe Messi will be the final piece of the puzzle...

LeBron James: Cleveland Cavaliers to Miami Heat, 2010

Basketball icon James announced he would sign with the Miami Heat instead of returning to his hometown team, the Cleveland Cavaliers. Then a two-time NBA Most Valuable Player and a six-time All-Star, James added to the spectacle of the stunning move by announcing it on a special television broadcast called The Decision. He enjoyed four years in Miami, where he won a pair of NBA titles, before returning to the Cavaliers in 2014. 

Tom Brady: New England Patriots to Tampa Bay Buccaneers, 2020

Few people expected Brady to leave the Patriots after 20 years and six Super Bowl victories. Not only did one of the game's greatest ever quarterbacks leave, but he joined one of the least successful franchises in NFL history and instantly guided them to glory, leading the Buccaneers to the franchise's second Lombardi Trophy with a 31-9 triumph over the Kansas City Chiefs in Super Bowl LV.

Luis Figo: Barcelona to Real Madrid, 2000

Should Messi ever return to Camp Nou as an opposition player it is unlikely he will be on the receiving end of the kind of abuse that greeted Figo. Barca fans threw bottles, lighters and even a pig's head at the Portuguese star when he went back to Camp Nou with Los Blancos in the seasons following his controversial move. 

Wayne Gretzky: Edmonton Oilers to Los Angeles Kings, 1988

In 1988, the Edmonton Oilers and Los Angeles Kings agreed a deal that shook the NHL to its core. The trade left Canada in disbelief, with a member of the country's parliament even proposing the federal government block the trade or buy Gretzky's contract and sell it to another Canadian team. "The Great One" would go on to enjoy eight successful years in Los Angeles before spells with St. Louis Blues and New York Rangers.

The old adage suggests life begins at 40, and in sports there have been several instances of stars celebrating glorious triumphs in the twilight of their career.

Phil Mickelson became the latest history maker on Sunday with a memorable US PGA Championship victory at the age of 50, making him the older male major winner of all time.

A two-shot victory over Brooks Koepka and Louis Oosthuizen made Mickelson a six-time major winner, and marked his first since he topped the leaderboard at The Open in 2013, aged 43.

But Mickelson is by no means the first sportsperson to prove that age is just a number. Here we remember some of the greatest achievements by those of advancing years (at least in sporting terms…).

BRADY BUCS THE TREND AT SUPER BOWL LV

When Tom Brady ended his lengthy association with the New England Patriots, some doubted whether he could emulate his unrivalled success at the Tampa Bay Buccaneers.

Those people were wrong. Already the oldest quarterback to have won a Super Bowl ring with the Patriots two years prior, Brady's memorable triumph with the Bucs over the Kansas City Chiefs at Super Bowl LV back in February saw him become the oldest player to win a ring, aged 43.

HOPKINS PUNCHES TICKET INTO THE HISTORY BOOKS

Boxing has a long history of fighters continuing well into their later years, and often times they prove ill-advised decisions.

But Bernard Hopkins certainly does not fall into that category. The all-time great first became boxing's oldest ever world champion when he defeated Jean Pascal in May 2011 to win the WBC and IBO light-heavyweight titles aged 46.

Two years later, he broke his own record by toppling Tavoris Cloud to win the IBF strap, and then in April 2014 – at the age of 49 – defeated Beibut Shumenov to add the WBA's belt to his collection.
 
FANGIO FINDS THE FORMULA TO SUCCESS

Revered by many as the greatest Formula One driver of all time, Juan Manuel Fangio certainly has a record to stack up against the best.

The Argentinian had seven full seasons in F1 and was world champion five times with four different teams and runner-up twice, while there were 24 wins from 51 Grands Prix.

The last of his F1 title-winning seasons occurred in 1957 at the age of 46, making him the series' oldest champion of all time.

NOTHING IS ZOFF LIMITS FOR VETERAN DINO

Dino Zoff is not the oldest player to ever feature in a World Cup fixture, that honour belongs to Essam El Hadary, who was 45 when he played in Egypt's final group-stage match against Saudi Arabia in 2018.

But the Italy legend does hold the record as the oldest player to win the World Cup when he lifted the trophy aged 40 years, four months and 13 days in a 3-1 victory over West Germany in 1982 in front of a bumper crowd of 90,000 in Madrid.

ROSEWALL AND SERENA ARE ACE

Serena Williams and her sister Venus have made a mockery of Father Time in women's tennis over the past two decades, while Roger Federer, Rafael Nadal and Novak Djokovic have dominated the men's game in their 30s.

But still, greatness should still be recognised and the last of Serena's grand slam titles at the 2017 Australian Open (when she was eight weeks pregnant no less!) saw her become the oldest female slam winner of all time.

In the men's game, the honour does not belong the three aforementioned modern-day greats (though who would bet against one of them doing it one day?). That benchmark lies with Ken Rosewall, who was 37 years, two months and one day old when he won in Melbourne in 1972.

PHIL TOPPLES BOROS

In the context of Mickelson's triumph, it seems only fair to mention the man who previously held golf's major benchmark.

Julius Boros was 48 when he won the 1968 PGA Championship. Indeed, golf is a game where players can excel much later in their careers.

Tom Morris and Jack Nicklaus were both 46 when they won the last majors of their glittering careers at The Open and the Masters respectively.

Tom Brady has signed a contract extension with the Tampa Bay Buccaneers that will keep him with the team through 2022.

Brady agreed a two-year deal with the Buccaneers last offseason after making the stunning decision to end his two-decade spell with the New England Patriots, which saw him win six Super Bowl titles.

Even more staggering was Brady's success in his first year in Tampa, where he won his seventh Lombardi Trophy as the Bucs became the first team in NFL history to win the Super Bowl at their home stadium, ending the Kansas City Chiefs' hopes of retaining the title in a 31-9 rout.

And he will stay with the Bucs for at least the next two seasons.

Brady has officially signed a four-year extension; however, three years of the deal are voidable ones included to help spread the cost of the contract.

According to ESPN's Adam Schefter, it is a move that saves the Buccaneers $19million in salary cap space in an offseason where the cap has shrunk from $198.2m to $182.5m because of the financial impact of the coronavirus pandemic.

Brady will be 45 when the 2022 season, effectively the final year of this deal, begins. He has previously stated his desire to play until 45, though has also said he is open to continuing further into his forties.

After intially struggling to hit the ground running, Brady enjoyed a stellar maiden season with the Bucs.

He threw for 4,633 yards and 40 touchdowns with 12 interceptions, his passer rating of 102.2 his highest since his MVP season of 2017 (102.8).

Only Deshaun Watson and Patrick Mahomes had more completions of 20 yards or more than Brady's 63 as he experienced a revival as a downfield passer in Tampa.

In the playoffs, he helped the Bucs come through a gauntlet, winning three games on the road to get to the Super Bowl. By defeating Mahomes and the Chiefs, the Bucs became the first team to win three games against former Super Bowl MVPs in the same postseason having also seen off Drew Brees and the Saints and Aaron Rodgers and the Packers.

Brady won his fifth Super Bowl MVP at Raymond James Stadium and will hope the extra financial flexibility his extension has given the Bucs can help him add to that tally over the next two seasons.

Tom Brady has signed a contract extension with the Tampa Bay Buccaneers that will keep him with the team through 2022.

LeBron James was inspired by Tom Brady's latest Super Bowl achievement, but the Los Angeles Lakers star has no timetable regarding how much longer he plans to play in the NBA.

At the age of 43, Brady – considered by many as the greatest of all time – won a seventh ring after leading the Tampa Bay Buccaneers to Super Bowl LV glory against the Kansas City Chiefs.

It means the superstar quarterback now has more rings than any NFL franchise and was particularly impressive given it was his first season with Tampa after a golden era playing for the New England Patriots.

James himself continues to dominate in the twilight years of his NBA career, and recorded a sublime triple-double of 28 points, 14 rebounds and 12 assists as the Lakers earned a 119-112 overtime win over the Oklahoma City Thunder on Monday.

Asked about Brady and his own career, James replied: "I mean he's one of the GOATs. 

"I've been watching him my whole life, or it seems like my whole life. I've been watching him 20 years now or however long he's been in the NFL. 

"I watched him when he was in Michigan, watched him quite a while now, just to see him go out and see the things he's done in his career, for him to win another one in the fashion that he won it was pretty cool. 

"It was very inspiring for a guy like myself. But it's two different sports, two different positions. I don't know how long I'll play the game, how much more I'll be able to give to the game. 

"But the way I feel right now, we'll see what happens. I have no timetable on it. I don't have no year of 30-this or 40-that. The game will let me know, we'll figure it out then."

The Lakers' win over the Thunder came just two days after the double-overtime triumph over the Detroit Pistons, following which James joked "my heart's not sustainable for two overtimes".

"It needed overtime in order for us to win this game," James added. "We did enough things to close in regulation but they forced us to take another five minutes. 

"I'm good with one! I get home a little earlier, my heart don't feel as bad it did the other night."

Serena Williams took inspiration from the "unbelievable" Tom Brady as she cruised into the second round of the Australian Open with a "vintage" performance.

Brady made yet more history on Sunday, the most successful player in NFL history winning a seventh Super Bowl as the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9.

The incredible Brady, 43, showed age is no barrier, throwing three touchdown passes – two of which were scored by his long-time friend Rob Gronkowski – and completing 21 of 29 throws for 201 yards.

Brady did now allow any interceptions as he picked up the MVP award at Raymond James Stadium.

Williams started her quest for a record-equalling 24th grand slam singles title with a 6-1 6-1 defeat of Laura Siegemund on Monday, then paid tribute to her fellow American Brady.

She said of his exploits: "It's unbelievable. I just was watching as much as I could to see. My only word is it's unbelievable. I kept saying: 'This is unbelievable, this is unreal'.

"You can't say it was the system he was at formerly [the New England Patriots]. It's definitely Tom Brady, he's Tom Brady. He's amazing."

Brady banished everyone from his house in the days leading up to the Super Bowl so he could fully focus on inspiring the Buccaneers to victory, but the 39-year-old Williams said she could never do the same as she would not want to be separated from her daughter, Olympia.

"I would not be able to go function without my three-year-old around," Williams said. "I think I would be in a depression.

"We've been together every day of her life, so... Is that healthy? Not at all! Not even close. But every single day I just want to be around her. It's great. Everyone's different.

"I can totally understand why he would banish because if I had the strength to do it, I would too.

"I could see it's definitely a distraction, especially every year that I've played except for the past few months, I finally am starting to get better at it. The first two and a half years was very difficult. I wasn't strong enough to do the banishment."

Williams, who will face Nina Stojanovic in the second round at Melbourne Park, was delighted with the manner in which she swept Siegemund aside and had no issues with her shoulder after withdrawing from a pre-tournament event citing an injury problem.

"This was a good start. Definitely vintage 'Rena'. It's definitely good. I think I'm pretty good at pacing myself in a grand slam," she said.

"I was happy just to get through it. Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So, it felt really good.

"Last year was very crazy for the world, and to be able to do what I love and to be able to come out and compete and play at a grand slam, after the last 12 months, it makes me appreciate the moment even more."

Tom Brady claimed a seventh Super Bowl crown after leading the Tampa Bay Buccaneers to their first Lombardi Trophy since the 2002 season with a dominant victory over defending champions the Kansas City Chiefs.

Tampa Bay Buccaneers quarterback Tom Brady is aiming to surpass "idol" Michael Jordan by winning his seventh Super Bowl ring.

No player has won more Super Bowl titles or appeared in more NFL showpieces than six-time champion Brady, who will lead the Buccaneers against reigning champions the Kansas City Chiefs in Super Bowl LV on Sunday.

Chicago Bulls and NBA great Jordan also won six championship rings during his Hall of Fame basketball career.

As Brady stands on the cusp of a seventh Lombardi trophy, the 43-year-old superstar told reporters on Monday: "Michael [Jordan] is one of my sports idols.

"I think he's pretty incredible and for me it's just about being a part of great teams.

"To have the opportunity to play in this game means a lot to me. It's a lot of commitment and sacrifice by a lot of guys.

"Obviously we're one game away from the ultimate goal in this sport. I've been a part of that ultimate goal six other times so they are all different and have all meant something a little different to me. They've all been unique in their own way. 

"It would be cool to accomplish it this time, I don't compare them to the other times, those were all magical moment of my life and no one can ever take those away from me.

"Hopefully we can finish this season strong and win a Super Bowl. That's why we're here, that's why we're playing, to make for a really magical season for us."

Brady – who will go head-to-head with reigning Super Bowl MVP Patrick Mahomes in Super Bowl LV on home soil – has more playoff wins since turning 35 (17) than any other quarterback has in his entire career, per Stats Perform.

Tampa Bay's Brady became the third player all-time with three-plus touchdown passes and three-plus interceptions in a conference championship game, joining Joe Montana (1981 NFC Championship) and Mark Malone (1984 AFC Championship), after the Buccaneers topped the Green Bay Packers in the NFC decider.

The 31-26 win in Green Bay was also the fourth time Brady has thrown three-plus interceptions in a playoff game, and his teams are 3-1 in those matchups (most such wins all-time) – his sides are 0-9 when he has three-plus interceptions in a regular-season game.

It was the 20th occasion Brady has led his team to 30-plus points in a postseason game – no other player has even half that total (second is Troy Aikman with nine). Brady's teams are 18-2 in those games.

Brady will feature in his 10th Super Bowl – the next most by a player is six by Mike Lodish and Stephen Gostkowski, after the Buccaneers became the fifth team all-time to win three road games in a single postseason.

LeBron James compared his achievements with the Los Angeles Lakers to Tom Brady's early success at the Tampa Bay Buccaneers as the legendary quarterback prepares for his latest Super Bowl appearance.

James, a four-time champion and four-time MVP in the NBA, led the Lakers to the title last year in just his second season in LA.

Meanwhile, Brady is in his first year in Tampa Bay, having ended a glittering career with the New England Patriots, and has taken the Bucs to next week's big game against the Kansas City Chiefs.

James turned 36 last month but is still averaging an impressive 25.2 points per game in 2020-21, a mark he has not dipped below since his rookie season in 2003-04.

Meanwhile, Brady – a three-time NFL MVP chasing a seventh championship – is now 43 yet ended the regular season with 40 touchdowns, the second best return of his career, and a passer rating of 102.2.

Neither man shows signs of slowing and James was asked on Saturday what he made of the continued excellence of a fellow sporting great.

"It doesn't do anything for me as far as what I do in my profession, but it does let me know – lets both of us know – that we can still play this game at a high level," James said after the Lakers' 96-95 win at the Boston Celtics.

"No matter how many miles, how many games, no matter how many dollars, no matter the statistics – in our respective professions, at our age, we can still dominate our sport.

"Also we can bring together groups that we may have not been around for long periods of time.

"It's our professionalism, how we attack the sport, how we attack every single day of being a professional, wanting to win every single day – in practice, on the film, in games, and so on and so on.

"We gravitate towards people and people gravitate towards us because we have one common goal and that's to win and to win at the highest level."

James had 21 points, seven rebounds and seven assists against the Celtics, ending the Lakers' first two-game losing streak of the season with his 854th career win – outright eighth on the all-time list.

"We didn't want to lose one and we lost two in a row, Philly and Detroit," he said, with the Lakers at Atlanta next in the final game of a seven-game road trip.

"We understood we were coming into a hostile environment and we know how good this team is.

"We'd have to play good basketball in order to win and we were able to win one possession more than they did."

Those fine margins came as Kemba Walker missed a game-winning chance for the Celtics in the final seconds, capping a dismal night on which he shot 1-of-12 from the field and 0-of-5 from three.

Walker scored only four points in just over 28 minutes; it was the seventh time in his career he had scored no more than four points in at least 28 minutes in the regular season.

"I thought I had a good look [on the final shot] but I struggled all game shooting the basketball," Walker said.

He added: "It's more mental, I think. I'm trying my hardest not to get frustrated but I thought tonight I got frustrated at myself and it put me in a bad place.

"I'm not the type of player to get frustrated – I'm always smiling and I wasn't that tonight. I got into my own head and, mentally, I hurt myself.

"I can't do that to this team. These guys look to me, especially when things are going tough. I can't put my head down and not mentally be engaged in the game like I was tonight."
