As of today, June 11th 2023, Novak Djokovic has to be considered the Greatest
Of All Time (GOAT) in men's tennis. He just won his 23rd Grand Slam singles
titles, surpassing Rafael Nadal's total of 22, for the most in the sport's history.
Djokovic has also been ranked world No. 1 for a record total of 387 weeks, and
he has finished as the year-end No. 1 seven times on the ATP tour, more than
any other male tennis player including the likes of Roger Federer, Ivan Lendl,
Pete Sampras, Andre Agassi, Jim Courier, Jimmy Connors, John McEnroe or Björn
Borg. Against this list of tennis players, he has won not only more Grand Slam
titles than the rest, he’s also the only male player to have won all four Grand
Slams twice, i.e., a 'sweep' of all four in one year.
