Novak Djokovic targets a record-equalling 20th major and sixth Wimbledon title from Monday which will edge him tantalisingly closer to becoming only the third man in history 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 even his closest rivals Roger Federer and Rafael Nadal have never managed.
"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 gold was a realistic target.
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.
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.
The Serb starts his defence on Monday against British world number 250 Jack Draper who was born just six miles (9.5km) from the All England Club.
Nadal, the Wimbledon champion in 2008 and 2010, has already withdrawn from this year's tournament, still scarred by the bruising loss to Djokovic in the French Open semi-finals.
