We live in an endless period where three tennis players find it difficult to break records and alter their leadership in alternate style.
Three of the best players in history have given so much to the game, as there will hardly be a trio of such a repetition.
In an age of such, it's hard to imagine that Roger Federer, Rafael Nadal or Novak Djokovic is still achieving improvement records.
However, the Serb will have an additional incentive to win the forthcoming Roland Garros, as it will be the first he won four consecutive titles in the Grand Slam is a professional tennis age.
Rod Laver did that at the start of the 1969 tension (and in a year), and Nole repeated in the period 2015-2016 in the same order as he could now.
Wimbledon and Open Open first won in 2015, and in 2016 Open Open Australia and Roland Garros.
Now, with a victory in Paris, the circle will end in the same order to record again with golden letters in the new history of tennis.
At the top of Nadal and Federer's careers, we still thought they could achieve it, but nothing had happened to them. It was difficult for people like Andy Murray, Stan Wawrinka, Juan Martin Del Potro or Marin Chilich in the tour.
A year ago, we could not imagine that Djokovic was able to achieve it after suffering a disappointing loss from Marko Chekinato at Roland Garros and was one of the lowest points in his career.
Since then, however, it seems irresistible in the helmet.
A total of eight men won the four titles, but only Rod Lever and his achievements in a year. This adds to the legendary Australian figure.
But taking the four in sequential editions is not so impressive – what Djokovic has been doing for the second time.
Federer failed to do so because of Nadal's dominance at Roland Garros, and the Spaniard himself lost his missing finals in Australia at the start of this decade.
Given the shape of Nolle, we cannot overlook the possibility of doing so again. But everything goes through Roland Garros, and especially Nadal, which a few days ago was downgraded to the final of Rome.
