N
ovak Djokovic is targeting a record-equalling 20th major and sixth Wimbledon title from next week, edging him closer to becoming only the third man to complete a calendar Grand Slam.
The world number one has already won a ninth Australian Open and second French Open this season.
That has put him halfway to emulating Don Budge (1937) and Rod Laver (1962 and 1969) in sweeping all four majors in the same year.
It is a feat that even his closest rivals Roger Federer and Rafael Nadal have never managed and will probably never achieve.
"Everything is possible," said 34-year-old Djokovic after winning the French Open earlier this month when asked if the Golden Slam of all four majors and Olympic Games gold was a realistic target.
"I've achieved some things that a lot of people thought it would be not possible for me to achieve."
Djokovic memorably captured a fifth Wimbledon in 2019, saving two championship points to defeat Federer in the longest ever final at the All England Club at four hours and 57 minutes.
He was deprived of defending his title in 2020 when Wimbledon was cancelled due to the pandemic.
However, Djokovic has been at this juncture before, winning in Australia and Paris in 2016 but coming up short at the Rio Olympics, Wimbledon and the US Open later in the year.
Djokovic has won seven of the last 11 Slams as he ramps up his assault on the record of 20 majors held jointly by Federer and Nadal.
Nadal, the Wimbledon champion in 2008 and 2010, has already withdrawn from this year's tournament, still scarred by the bruising loss to the Serb in the French Open semi-finals.

Eight-time winner Federer, meanwhile, will be 40 in August and won just one match on grass at Halle in the build-up to Wimbledon.
Federer, who underwent two knee surgeries in 2020, won the last of his eight Wimbledons in 2017 and the most recent of his 20 majors in Australia in 2018.
The Swiss star has lost three finals to Djokovic at the All England Club in 2014, 2015 and the epic 2019 clash.
"It's a huge challenge for me," said Federer of his comeback.
"Things don't come simple, they don't come easy."
The rest of the current top 10 have endured so far mediocre Wimbledon records.
Only 33-year-old Roberto Bautista Agut, a surprise semi-finalist two years ago, has got beyond the last 16.
Daniil Medvedev has a best of the third round, while Dominic Thiem, who made the fourth round in 2017, crashed at the first hurdle in 2018 and 2019.
Alexander Zverev had a best last 16 run in 2017 but was also a first-round loser two years ago while Andrey Rublev has yet to get past the second round.
Of the remainder of the top 10, French Open runner-up Stefanos Tsitsipas and Matteo Berrettini are Djokovic's most likely threats.
Tsitsipas made the last 16 in 2018 before exiting in the first round two years ago.
The Greek, however, is one of the form players of 2021, winning titles in Monte Carlo and Lyon before forcing Djokovic to recover from two sets down in the Roland Garros final.
Queen's Club champion Matteo Berrettini is also a dangerman for Djokovic.
The Italian made the last 16 in 2019 where it took Federer to stop his progress.
He was also the first man to win the Queen's title on debut since Boris Becker in 1985 — the German went on to win a maiden Wimbledon just weeks later.
Andy Murray, the 2013 and 2016 champion, will hope to ride a national wave of emotion at least into the second week.
But the injury-plagued Briton, a former world number one, is down at 119 in the rankings and has won just two matches all season.
