It's a fact that 'free' transfers in football are, all things considered, quite expensive. Wages, signing fees, agent demands and general costs make any such deal have a sizeable imprint on a club's balance sheet.

Still, Paris Saint-Germain's signing of Gianluigi Donnarumma for a big fat zero in transfer fees sounds like a sensational piece of business – particularly after his Euro 2020 heroics.

The Italy goalkeeper has left Milan, his boyhood club, to join Mauricio Pochettino's side where he hopes to be able to challenge for the biggest club trophies, most obviously the Champions League.

Certainly, Donnarumma is right to aspire to the top prizes. This is a player who made 200 appearances for the Rossoneri by the age of just 21 years and 146 days, who was valued at €170million by agent Mino Raiola when he was just 16.

PSG have secured a bargain, for sure – but is it one they really needed? Incumbent number one Keylor Navas certainly did not seem to think so when he posted to Instagram "gift your absence to those who do not value your presence" shortly after the Donnarumma rumours first emerged.

As Opta data shows, Navas, a four-time Champions League winner, may well have a point.

First, it's important to stress once again that Donnarumma is an excellent signing. PSG are recruiting a highly experienced yet young goalkeeper without paying a transfer fee; a goalkeeper whose market value is only likely to increase over the coming decade – indeed, it has in the past week alone – should Les Parisiens decide to cash in at any point.

However, it's also true that, if the short-term goal is simply to improve the first XI with a view to winning the Champions League, replacing Navas with Donnarumma may not be a fool-proof move.

In 2020-21, Donnarumma kept 14 clean sheets in 37 matches in all competitions. Navas also managed 14 shut-outs, having played in eight fewer games. The Costa Rican conceded only 18 goals in those matches, whereas Donnarumma let in 38.

Donnarumma produced more saves (92) than Navas (74), but the older man's save percentage was far higher: 80.43 per cent, compared to 70.08. In fact, Navas boasted the highest save percentage of any keeper in Europe's top-five leagues last term who started at least 10 matches, a fraction above Atletico Madrid's Jan Oblak (80 per cent). Donnarumma came 25th in those rankings.

Navas' distribution was better, too: his passing accuracy (85.65) was better than that of Donnarumma (77.04), with only three regular keepers in Europe's top-five leagues posting better numbers. Donnarumma did at least surpass Navas for keeper sweepings, which are defined as any time a keeper anticipates danger and rushes off their line to try either to cut out an attacking pass (in a race with the opposition player) or to close down an opposition player: he completed nine of nine such 'sweepings', with Navas on five out of five.

Going further and looking at expected goals on target – a way of building on expected goals that takes into account the quality of the attempt on goal – we can highlight how well these keepers have done to keep high-quality shots on target from going in. This is done by subtracting goals conceded (excluding own goals) from xGOT conceded, giving us 'goals prevented'. And it's another big tick for Navas.

In Ligue 1 last term, if we exclude penalties and own goals, Navas let in 17 goals from an xGOT conceded total of 24.1, giving him a figure of 7.1 goals prevented. In other words, he would reasonably have been expected to concede roughly seven more goals based on the quality of shots on target he faced. Meanwhile, Donnarumma conceded 35 from an xGOT of 34.1, giving him a goals prevented figure of -0.9 – not terrible, but nothing to shout about.

Last season's figures were not isolated, either. If you look back over Donnarumma's 215 club appearances since his Milan debut on October 25, 2015, Navas' consistency as a shot-stopper is superior.

Donnarumma conceded 227 goals for Milan (excluding own goals) in all competitions from an xGOT figure of 244.4, giving him a goals prevented tally of 17.4. That's a strong return – better, for instance, than Manchester United's David de Gea (16.6) and Liverpool's Alisson (16.1) – but, again, it's lower than that of Navas (20.3).

For balance, both of them are a long way behind the top performer in this metric over that time frame. That man, unsurprisingly, is Jan Oblak of Atletico Madrid, with a quite remarkable goals prevented figure of 44.5.

It's as yet unclear what Navas' plans will be now that Donnarumma has moved to Parc des Princes, but a keeper with his pedigree and medal collection is unlikely to settle for a back-up role. And nor should he: Donnarumma might be PSG's future, but Navas does not deserve to be dispensed with in the present.

Patrik Schick's sensational long-range strike for the Czech Republic against Scotland has been voted Euro 2020's Goal of the Tournament.

The Bayer Leverkusen forward scored twice in the 2-0 win at Hampden Park on matchday one in the group stage, the second of those goals from just inside the Scotland half.

The goal was measured at 49.7 yards, making it the furthest distance a goal has been scored at the European Championship since such data was first recorded in 1980.

Schick spotted opposition goalkeeper David Marshall off his line and left the back-pedalling Scotsman red faced to overtake Torsten Frings' previous record of 38.6 yards for Germany against the Netherlands at Euro 2004.

Speaking after the match on June 14, Schick confirmed he had spotted Marshall off his line earlier in the contest and decided to have a go from range.

"I knew he liked to stay very high, so when the ball came, I quickly checked where he was standing, and it was a nice goal," he told BBC Sport. 

"I saw the keeper off his line. I checked already in the first half and thought maybe this situation will come."

The goal was voted the best from a shortlist of 10 compiled by UEFA's Technical Observer team, with nearly 800,000 votes being cast by the public.

Schick finished level with Cristiano Ronaldo as Euro 2020's top scorer with five goals in five games, but the Portugal superstar was awarded the Golden Boot as he also had one assist.

The 25-year-old's return of 81 minutes per goal was the third best of any player to have scored more than once in the tournament, behind Denmark's Kasper Dolberg (75.33) and Ronaldo (72).

Tadej Pogacar took another giant leap towards defending his Tour de France title with victory up the Col du Portet on stage 17.

The UAE Team Emirates rider benefited from excellent work by his team-mates on the brutal 178.4 kilometre route, which started in Muret.

Rafal Majka in particular was worthy of great praise in aiding the cause of Pogacar, setting the Slovenian up brilliantly to push for the stage win on the final hors categorie climb.

Anthony Perez, the lone man remaining from the breakaway, was reeled in on the last of the three ascents with 8.5km remaining.

It was Pogacar, Jumbo-Visma's Jonas Vingegaard and Richard Carapaz of INEOS Grenadiers, who emerged as the frontrunners for the stage.

Despite dealing with gradients of 13 per cent, Pogacar always looked comfortable and there was never any doubt he would respond when Carapaz attacked 1.5km from a finish 2,215km above sea level, the highest of this year's Tour de France.

There was an element of surprise to that move, Carapaz having done little to help Pogacar and Vingegaard manage the climb while looking on the verge of being dropped.

But Pogacar called his bluff and it was he who clearly had the most left in the tank, surging clear in the final 200 metres to claim his second stage win of this year's Tour.

His lead at the top of the general classification stands at five minutes and 39 seconds from Vingegaard with three stages left before the final processional ride to the Champs-Elysees on Sunday.

Does Pogacar have enough left in his legs for another hors categorie finish. The penultimate and final ascents are on the 129.7km ride from Pau to Luz Ardiden are each HC climbs as the Tour sees it's final mountain stage of 2021.

Given his lead in the GC, Pogacar does not need to make such an effort, but he might have the appetite for another win to emphasise his dominance on stage 18.

Dustin Johnson says he needs to "step up my game" as his battle with Jon Rahm for the world number one spot continues at the Open Championship.

Two-time major champion Johnson briefly lost top spot to Rahm after the Spaniard won the U.S. Open last month.

But the American is back on top for the Open at Royal St George's having reclaimed first place without playing last week when Rahm finished seventh at the Scottish Open.

"The rankings, they're tough to figure out, but yeah, obviously if you play well, you get to number one," Johnson said after his practice round with Rahm at the Kent links course.

"I need to continue to play well if I want to stay there. 

"Obviously Jon has been playing really well lately. I need to step up my game a little bit."

Johnson has only made one top 10 in his past 10 events but believes his game is returning to how it was in a fantastic finish to 2020 and a strong start to this year.

"Yeah, obviously I had played really solid there really for about six, seven months," he said of the spell around his Masters win last November. 

"I feel like the game is starting to get back to where it was, just seeing a lot more consistency with the shots and the shapes. 

"I think that's probably just a little bit of the difference. Putting, I felt like I putted consistently well for that time period, so just been working on the putter a lot – that ultimately can be the difference."

Johnson came so close to glory when the Open was last played at this course in 2011, in contention before a double bogey at 14 as he ultimately finished in a tie for second and Darren Clarke took the title.

He added: "That was a long time ago, but obviously I have good memories here, and I did play well. 

"I do like this golf course. I feel like it's a tough golf course, a typical links course. For me, I feel like most of it's going to be driving. If I can drive it well, then I feel like I'm going to have a really good week.

"It was a little bit firmer in 2011. Obviously they've had a lot of rain and the rough is definitely a little bit thicker than it was back then." 

As well as that near miss, Johnson has had top-10 finishes in 2012 and 2016, with the prospect of winning his first Claret Jug an enticing one.

"It would definitely be right up at the top," Johnson said when asked where an Open win would rank for him.

"It's obviously a major. It's a tournament where I've been close quite a few times. I really like coming over here and playing. Yeah, it would be right up at the top with the rest of them.

"I think it's shaping up to be a great Open Championship."

Mauro Icardi opened the scoring and Achraf Hakimi started as Paris Saint-Germain got their pre-season up and running with a 4-0 win over Le Mans.

Wing-back Hakimi, signed from Inter after he helped the Nerazzurri win Serie A last season, was handed his first, unofficial start for PSG in the training ground match on Wednesday.

The former Real Madrid youngster teed up PSG's second goal, squaring for Ismael Gharbi to sweep home from the centre of the area.

Mauricio Pochettino's team had gone ahead in the 12th minute against their second-tier opposition, with Icardi on hand to head home after the Le Mans goalkeeper had parried Julian Draxler's cross into his path.

Icardi scored 20 goals in his first season at PSG, on loan from Inter, but failed to replicate that level of performance last term, netting just 13 times.

Bandiougou Fadiga replaced Icardi at half-time, and his 87th-minute strike made it 3-0 before fellow substitute Xavi Simons rounded off the scoring.

Lewis Hamilton will hope returning home for the British Grand Prix and a new sprint race format can kickstart Mercedes' faltering challenge in the Formula One title battle.

Round 10 of the 2021 season takes place at Silverstone, a venue where Mercedes have won seven of the last eight races.

Six of those triumphs came for Hamilton and he has a total of seven British Grand Prix wins, having also triumphed there for McLaren in 2008.

That is already a record for most F1 wins at a driver's home circuit and if he can secure an eighth victory, he will match Hungary – which is next on the calendar this year – as his most successful race.

Victory will not come easily, though, with Max Verstappen coming into the event after winning three races in a row for the first time in his F1 career. 

The in-form Red Bull star has built an impressive 32-point advantage over Hamilton in the drivers' championship that could have been bigger were it not for his late tyre woe in Baku.

Verstappen has taken one more pole position this year (four) than in the rest of his F1 seasons combined (three).

The constructors' standings are also looking good for Red Bull, who are 44 points clear.

Two straight podiums for Valtteri Bottas have come at a good time as he fights for his Mercedes future, while Sergio Perez – who sits third in the drivers' standings – will want to recover from a ragged race in Austria.

LAST TIME OUT

Verstappen eased to yet another victory at the Red Bull Ring, as he won in front of huge support at the Austrian Grand Prix to complete a triumphant triple-header having won in France prior to the two races at his team's home circuit.

The Dutchman led from start to finish again after claiming pole.

Hamilton's hopes of reeling him in – dismissed as "out of the question" after qualifying – were hindered by another fine drive from Lando Norris, with the Mercedes great starting where he finished in fourth.

Bottas was the big mover, up from fifth to second, benefiting from keeping clear of controversy as numerous drivers – notably including Norris and Perez – tangled in costly fashion.

Norris claimed a superb third despite a time penalty and has now collected points in 14 consecutive races – his longest streak and the best ongoing run in the series. Fernando Alonso in 2007 was the last McLaren driver to enjoy such a stretch.

Carlos Sainz took fifth ahead of Perez, who was hit with two penalties.

WHAT TO LOOK OUT FOR AT SILVERSTONE

The new sprint event and revised race weekend format is undoubtedly the most intriguing aspect that will be closely followed at Silverstone.

Qualifying will take place on Friday, which sets the grid for the first-ever sprint race in F1 on Saturday, with all cars to be fitted with soft tyres.

The results of the sprint race, which will last 100km – around 17 laps – will then determine the grid for Sunday.

Points (three for the winner, two for second and one for third) will also be awarded in the sprint race, with drivers getting a free tyre choice for sprint race and the main grand prix.

Practice, meanwhile, will be cut from three sessions to two.

Aside from the new format, Mercedes are bringing an upgrade to the circuit, which Hamilton and Bottas will hope revitalises their fortunes in the battle against Red Bull.

TOP FIVE OPTA STATS

Super Silverstone – This will be the 55th race at the famous circuit, which has held more grands prix in F1 than all but two tracks – Monza (70) and Monaco (67).

Hamilton hope – Having finished fourth in Austria, Hamilton is bidding to avoid finishing two consecutive races outside the podium for the first time since 2017 (Mexico and Brazil).

Pole drought – Mercedes have gone five consecutive races without reaching the pole position in F1, their worst run since 2019 (seven between Hungary and Mexico).

Mercedes misery – Toto Wolff's outfit are winless in their last five GPs, their worst run without a win in the Hybrid Era (since 2014) and as many races without finishing first as in their previous 17.

Red Bull flying high – The team have won six races in 2021 including the last five. The last time they won so many in a season was in 2013, when Sebastian Vettel won the championship for them.

The Phoenix Suns enter Game 4 of the NBA Finals with a difficult question to answer: how can they contain Milwaukee Bucks star Giannis Antetokounmpo when Deandre Ayton is not on the court?

Milwaukee cut Phoenix's lead in the series to 2-1 with a 120-100 victory on their home floor in Game 3.

It came behind a scintillating 41-point performance from Antetokounmpo, the two-time league MVP delivering a performance few could have foreseen when he hyperextended his knee in Game 4 of the Eastern Conference Finals.

Antetokounmpo also had 13 rebounds in putting up a decisive double-double, taking advantage of another knee injury that could well prove a turning point in the series.

The Suns were without Dario Saric, the backup to starting center Ayton, in Game 3 because of a torn anterior cruciate ligament suffered in Game 2.

Coach Monty Williams initially went with Frank Kaminsky as Ayton's deputy, but also attempted to play small ball with Torrey Craig and Abdel Nader.

The plus-minus numbers for Kaminsky (-12), Craig (-12) and Nadel (-5) tell their own story. Milwaukee dominated when Ayton was not out there, outrebounding the Suns 47 to 36.

In this series, when Ayton has been on the court, the Bucks average 110.0 points per 100 possessions, compared to 125.3 with the former first overall pick off the floor.

Milwaukee's rebounds per 100 possessions with Ayton on the bench jump to 50.3 from 46.8 when he plays.

Similarly, the Bucks are substantially more effective from the three-point line without the presence of Ayton to deal with, converting 46.4 per cent of their shots from beyond the arc in the series compared to 34.7 when he is trying to stop them.

For all the attention lavished on Devin Booker and Chris Paul, Ayton arguably stands as the key player for the Suns if they are to claim a first NBA title.

Should there be a repeat performance in Game 4 on Wednesday when Ayton is forced to rest, then Antetokounmpo will have an excellent chance to improve his Finals average of 34.3 points per game and, more importantly, help the Bucks level the series.

PLAYERS TO WATCH

Milwaukee Bucks – Brook Lopez

Another player who can capitalise on the blow the Suns have suffered to their big man depth is Lopez, the Bucks center who is averaging 6.7 points in the paint per game in the series – behind only Antetokounmpo and Ayton.

Lopez has produced double-digit points in four of his past five outings in this postseason, including a 33-point effort against the Atlanta Hawks in Game 5 of the Eastern Conference Finals as the Bucks prevailed without the injured Antetokounmpo. Third in effective field goal percentage (60.9) among centers with 30 attempts or more this postseason, Lopez could compound the impact of Saric's absence for the Suns.

Phoenix Suns – Deandre Ayton

That his Finals numbers are inferior to those of Antetokounmpo is largely reflective of the point-scoring and creative burden taken on by Booker and Paul respectively. However, Ayton is the Suns player most should have their eyes on in Game 4.

He has averaged 35 minutes in this series compared to 37.7 for Antetokounmpo; will Williams up Ayton's time on the court in response to the events of Game 3 when he rested? Or will the Suns coach find a way to minimise the damage during Ayton's time on the bench? The answers could eventually decide the destination of the Larry O'Brien Trophy.

Javier Tebas will not turn a blind eye to LaLiga's financial fair play rules to allow Barcelona to keep Lionel Messi.

Barca president Joan Laporta said this week that talks with Messi, who became a free agent for the first time in his career this month, were "progressing adequately".

And reports on Wednesday claimed Messi had agreed a new five-year contract with Barca that will pay him half his original salary.

Speaking prior to the emergence those reports, LaLiga president Tebas rejected the notion he could ignore salary cap rules to allow Barca to retain the services of the Argentina superstar.

In doing so, he hinted Barca could come under scrutiny from the league if they release players or staff to enable them to keep Messi.

"No, I won't [turn a blind eye] for Messi, it's impossible. There are many workers [at LaLiga] and in the economic control [department] as well," Tebas told Radio Marca.

"We often have to explain [the economic controls] to agents and players because they don't know about it or think clubs are deceiving them, and we've had to explain it in recent years.

"We'll have to analyse everything properly, because if there are dismissals for economic reasons but then they bring in Messi and others... we'd have to look into that.

"Right now, I can only give my opinion, and that is that it is odd that there has been no offer [for Messi] from Manchester City or Paris Saint-Germain.

"And I firmly believe there isn't and that the player wants to stay."

Messi is coming off a 2020-21 season in which he scored 38 goals in all competitions, the fourth-most across Europe's top five leagues behind Robert Lewandowski (48), Kylian Mbappe (42) and Erling Haaland (41).

The sole reward for his efforts was the Copa del Rey, as Barca missed out on LaLiga and lost in the last 16 of the Champions League to Mbappe and PSG.

However, he crowned the campaign with his first senior international trophy, helping Argentina to triumph in the Copa America on Saturday as they defeated Brazil 1-0 in the final.

The British and Irish Lions have been handed a huge boost with the news that captain Alun Wyn Jones will join their tour of South Africa – less than three weeks after he suffered a dislocated shoulder.

Jones, 35, sustained the injury during the Lions' warm-up game against Japan at Murrayfield on June 26, but he will fly into Cape Town on Thursday.

The veteran lock came through a training session with the Wales squad at their Vale of Glamorgan base this week before successfully undergoing a medical assessment.

"We are delighted to welcome Alun Wyn back," said head coach Warren Gatland. "It'll come as no surprise to anyone who knows Alun Wyn that since injuring his shoulder against Japan, he's done everything he can to get himself back.

"It's remarkable really when you consider it's just 18 days since he left us in Edinburgh.

"He's been training with the Wales squad at the Vale since last week and yesterday he had a proper hit out. Following assessment from the medical staff this morning we're satisfied he's fit to return.

"He's obviously raring to go and from what I've seen on video and the feedback we’ve received, he's certainly not been holding himself back in training. He was really getting stuck in yesterday.

"It’s a massive boost for the Lions to welcome a player of Alun Wyn's stature back."

Following high-scoring wins in their first three matches against franchise sides, the Lions face what is expected to be the toughest examination of their tour so far when they take on South Africa A in Cape Town on Wednesday.

Roger Federer's body has been saying no for the past two years, but Pat Cash is hopeful the 39-year-old will return for another run on the ATP Tour.

After suffering a setback to his longstanding knee injury during Wimbledon, the 20-time grand slam champion has this week withdrawn from the Tokyo Olympics.

Despite being without much match practice – playing just four tournaments before Wimbledon after coming back from two knee surgeries - Federer was able to make the quarter-finals at All England Club.

However, he suffered a demoralising loss to Hubert Hurkacz in straight sets in the last eight that promoted a fresh round of speculation over his future in the game.

Cash, who won Wimbledon in 1987, hopes Federer will be back despite his recent injury woe.

He told Stats Perform: "First of all, let's hope that Roger Federer will keep going. 

"I think he can, I think he just needs more matches and probably needs to make sure that he's able to last. 

"But your body starts saying no at some stage and it's been saying that for a couple of years now for him." 

Wimbledon winner Novak Djokovic is now level with Rafael Nadal and Federer on 20 slams.

Cash believes judging the Swiss star purely on grand slam titles is not a fair measure of his brilliance, pointing instead to his astonishing record totals of 58 major quarter-final berths and 46 semis.

"He has been the most consistent player that I think we've ever seen," Cash said. "He may not end up with as many grand slams but his consistency is just outrageous.

"All the other players have lost early in grand slams, the Djokovics, the [Andy] Murrays, then the Nadals had lost early in grand slams, Roger just doesn't do it.

"Of all the titles that he's won, I think for me, his most impressive record is how many semi-finals or quarter-finals in grand slams in a row that he got to. It was something ridiculous for 10 or 11 years.

"He never failed at any grand slams and that is just absolutely mind blowing."

However long he tries to play on, Cash insists nothing can sour the memories of an extraordinary career from Federer.

Cash added: "Obviously, he raised the bar as far as the standard of tennis has gone. 

"The other players really had to catch up. Novak admitted it, he said, 'Without Roger there, leading the way, I wouldn't have been as good a player as I could have been'. 

"That's the gold standard of Roger Federer over his career and I'm not sure anybody will be as consistent as him in tennis history. 

"He's just phenomenal the way he plays, and we all of course enjoy the style, his movement. And he's a class act off the court as well."

Federer's status for the US Open, which begins on August 30, is unclear, with Djokovic looking to take the outright lead for major titles and achieve a historic calendar year Grand Slam.

Lee Westwood is entering The Open Championship optimistic he can contend as he hopes to have cleared the "mental block" he had at Royal St George's.

The 48-year-old fell away from a promising position at the Scottish Open last week but is confident his game is in a good place.

Westwood missed the cut in 2003 and 2011 when the tournament was last played at the Kent links, but he has attempted to banish those memories for the last major of 2021.

"Coming into this week, I've played here twice in the Open Championship, missed the cut both times," he said.

"Kind of had it in my head, a bit of a mental block that I didn't like the golf course, but I played it [on Tuesday] and really enjoyed it. 

"I loved the way it was set up. I couldn't really remember the golf course too much, probably because I didn't have that much experience of playing on it, only having played two rounds each Open. 

"I really enjoyed it. Enjoyed the conditions and it sort of turned my head around and made me look forward to the week even more really. 

"I'm positive and hoping I can find some form and get into contention. Like all links tournaments, you need a little bit of luck with the weather, you need some good breaks.

"I did win around here as an amateur, so I've had some kind of form around here in the past. I'm just trying to look at it more positively than I've missed two cuts. 

"There will be underlying facts there; I might not have been playing well or my head might not have been in the right place. 

"I feel like if I get my game where it needs to be and it's good for that week, I can contend."

Phil Mickelson won the US PGA Championship to become the oldest major champion at the age of 50 this year.

Westwood was therefore asked if that meant he still had hope of winning one as he prepares to make his 88th major appearance.

He said: "We're from a generation that's maybe had the benefit of sports medicine and maybe a little bit more analytical, knowing what's going on. 

"Tiger [Woods] came on the scene and everybody sort of took that a little bit more seriously mid to late '90s. All the other players that wanted to get ahead of the game sort of looked to him.

"Rather than [golf being an] 'I've been working out for six months thing' and 'this is a quick-fix thing', it's a long-term thing with the likes of myself and Phil, Stewart Cink, people like that playing.

"Look at Bernhard Langer – he's playing well into his 60s because he's looked after himself 30 years ago, not because he started going in the gym three weeks ago. 

"Mine and Phil's generation are now reaping the benefits of the hard work for the last 20 years, analysing movements in the swing and working on injury prevention to those parts of the body that get injured."

Novak Djokovic will never have a better opportunity to achieve a historic calendar Grand Slam, which former Wimbledon champion Pat Cash says he should prioritise at all costs.

The Serbian won a sixth Wimbledon crown on Sunday, defeating Matteo Berrettini in four sets to achieve a final victory that moved him on to 20 grand slam titles.

With Australian Open and French Open successes also already achieved, glory at the US Open would see Djokovic become only the second men's player in Open Era history to win all four majors in the same year.

Cash thinks the stars have aligned for Djokovic, with issues for his main rivals leaving the 34-year-old primed to achieve the famous feat in 2021.

"The impossible dream really is there," Cash said to Stats Perform.

"For Novak this year it is a great opportunity for him to grab a bunch of grand slams and grab all the titles. 

"Certainly Wimbledon – without disrespecting the other players – was one of the weaker men's side draws that I've seen in many, many years. 

"And that's because we've got two of the big stars coming back from injuries – Andy Murray and Roger Federer – who played well but weren't at the peak of their career.

"The younger players are coming through but they're not quite there yet and Novak is just sitting on top of that mountain as the King of the Castle.

"His performance was exceptional at Wimbledon, there's no doubts about it. 

"The slightly younger players are coming through – Berrettini obviously in the final really pushed him to just about the limit.

"Stefanos Tsitsipas in the French Open final up two sets to love. So, these guys are close, very close, and it won't be long before they catch up with Novak and the others. 

"Obviously Rafa [Nadal] was out of this Wimbledon as well – I don't really think he's a serious threat on the grass anymore but he's still a great competitor. 

"So these guys are catching up, Rafa is still there, maybe Murray will come back and Federer will come back and be in better shape in the next year – but this is the year that Novak can really grab." 

Djokovic admitted this week he is still "50/50" over whether he will take part in the upcoming Tokyo Olympics due to coronavirus countermeasures in the Japanese capital. 

Federer withdrew from the tournament on Tuesday and Cash insists Tokyo will not be the priority over glory in New York for Djokovic.

Cash added: "It's the Olympics, okay – maybe he wants to do that, but certainly his goal is now to try and win all four grand slams in the calendar year.

"He has done four in a row, but he hasn't done them in the same year, which is very, very tough to do. 

"There is a reason why I think one person has done it in [men's] professional tennis – Rod Laver and it was in 1969, so it's not easy to do. 

"But I really do think it's in his sights and that has got to be his priority. 

"It's absolutely the absolute peak of our sport to win all four grand slams in one year." 

With Djokovic now level with Federer and Nadal on 20 majors, Cash would not be surprised to see him build a big lead.

He added: "Look, it's very hard to say. We have all been proven wrong by the numbers. 

"Though most of us thought that Rafa and Novak would get pretty close to Federer, we didn't really think they'd get there and beyond. 

"I think Novak is likely to win another couple, but you know, it takes us one little injury [to derail him] so it is very hard to say.

"John McEnroe said 25 or so [for Djokovic] and that could be well within his reach at the moment. 

"He's improving and that's frightening to think. He's won 19 grand slams before Wimbledon, and all of a sudden we've seen this guy come to the net, volley, add another string to his bow to become a better player. 

"Yeah, age 34 and he is improving – that's pretty frightening." 

After an enforced absence in 2020 due to the coronavirus pandemic, The Open is thankfully back on this year's golf calendar.

Royal St George's will host the 149th edition of the tournament, a welcome return to the Kent course that saw Darren Clarke triumph a decade ago.

Shane Lowry is the defending champion, having prevailed at Royal Portrush in 2019, but can he retain his crown? Will one of the big guns instead get their hands on the famous Claret Jug, or could another long shot follow in the footsteps of Ben Curtis, an unlikely champion at the venue back in 2003?

Ahead of the opening round, it is time to take a look at some of the players who could be in contention for glory in the final major of the year.

RAHM READY FOR OPEN CHALLENGE – Nicholas McGee

Jon Rahm has struggled to capture his best in four previous appearances at The Open, just one of which has seen him finish with an under-par score (-3 in 2019). However, only in 2018 has he missed the cut, and his blistering form in 2021 suggests he should be firmly in the mix this week.

His 11 top-10 finishes rank as the most on the PGA Tour this season. Rahm also leads the tour in scoring average (69.6) and in strokes gained (2.02 avg). Second in strokes gained tee to green and (1.82 avg) and fifth in greens in regulation (71 per cent), Rahm has displayed consistency that should lend itself to links golf. Further optimism came with a seventh-placed finish at the Scottish Open. The stage looks set for him to emphatically turn his Open fortunes around.

SPIETH HAS THE BELIEF – Russell Greaves

Jordan Spieth has three key things in his favour at this tournament: he's a man in form, he's exceptional with the putter, and he's won it before. The 2017 Champion Golfer of the Year has an overall putting average of 1.566 on the PGA Tour in 2021, placing him seventh in that metric.

That showing on the greens has laid the foundations for a year in which the 27-year-old has enjoyed eight top-10 finishes. He was in a tie for third at the Masters and boasts a career aggregate score of 21 under at the Open Championship, marking him down as a leading contender in Kent.

NO DOUBTING THOMAS AFTER RECENT RUN – Dan Lewis

Justin Thomas has struggled on the links in his career but ended up in a tie for eighth at the Scottish Open last week – his first top-10 finish since winning the Players Championship in March. He opened and closed with rounds of 65 at the Renaissance Club, where he used a new putter, and has not carded a bogey in his last 25 holes.

The 28-year-old may not be among the top group of contenders, but the 2017 US PGA Championship winner is certainly capable of carrying his momentum into this event to claim a second major in his career.

DUSTIN'S TIME TO HAVE A MAJOR IMPACT - Timothy Abraham

The form book might be against him, but world number one Dustin Johnson can have a Claret Jug-shaped silver lining to a disappointing 2021 in the majors. The American failed to make the cut at both the Masters and the US PGA Championship, alongside a 19th-placed finish in the U.S. Open this year.

An aggregate career score of +15 in The Open is hardly the stuff of a potential champion, but a decade ago he tied second behind champion Clarke. Johnson is a better player now, and the type of optimist capable of winning a major out of the blue. Write him off at your peril.

GLORY FOR RORY AGAIN? ABSOLUTELY! – Chris Myson

The Open champion in 2014, Rory McIlroy is rightly seen as a contender in Kent. He did miss the cut at this tournament in 2019 – but that was the first time he has done so since 2013.

When the Northern Irishman gets to the weekend at The Open, he is usually competitive. He had four consecutive top-five finishes prior to his previous disappointing outing and has a total of five in his career, including that triumph seven years ago. A top 10 at the U.S. Open gave McIlroy some much-needed major momentum and he can now finish with a flourish in his final opportunity this year.

HATTON CAN LINK IT ALL TOGETHER - John Skilbeck

Considering the winners Royal St George's has thrown up in the 21st century - Curtis and a past-his-prime Clarke - you might as well stick a pin in the field and take your chances. Tyrrell Hatton has twice won the Dunhill Links Championship which points to him knowing how to handle an Open course, and he has scored victories on each side of the Atlantic in the past 18 months so brings recent experience of closing out tournaments successfully.

Whether he wins or not is another thing: there are missed cuts on his Open Championship CV. However, two top-six finishes in the last four editions suggests the Englishman might not be far away.
