Another indefatigable comeback saw him win the French Open final, putting Djokovic on 19 Grand Slam titles versus the 20 of his two great rivals.
This, however, might go down as the one that effectively seals the outcome of the cosmic competition between the greats. Roger and Rafa may fear that it’s all over — and it probably is now.
Even with only a fortnight this year between Roland Garros and Wimbledon, Djokovic will head to SW19 with every chance of drawing level.
And he warned he would not let up in his quest to overhaul Federer and Nadal. ‘I never thought it was a mission impossible to reach the Grand Slams of these guys,’ he said.
‘I’m not there, but I’ll keep on chasing. I’m going for the title at Wimbledon. Of course I am. I’ve had great success in the last couple of Wimbledon seasons that were played.’
Djokovic defeated Stefanos Tsitsipas 6-7, 2-6, 6-3, 6-2, 6-4 in four hours and 11 minutes — 60 seconds longer than it had taken him to overcome Nadal on Friday night.
The young Greek discovered there is no harder man to put away over five sets and the 34 year-old Serb now becomes the first player in the post-1968 Open era to have won all four majors at least twice.
For a fleeting moment, it looked like the 22 year-old from Athens was about to blow up the long-established order in the game, which he may himself dominate in future.
Yet that is to underestimate Djokovic and overestimate his tendency to go through strange fluctuations of energy over the course of a long match, as he did in the second set.
The champion said: ‘I just tried to stay with him in the third and find my window, and after the third set I knew I could do it. I felt like he was starting to overthink, I got into his head.’
Djokovic, who displayed the same resolute calm he had shown against Nadal, added: ‘The atmosphere was amazing. Unforgettable matches, unforgettable moments for my career, my life. I’ll definitely remember this last 48 hours for the rest of my life.’
At Wimbledon he might be more vulnerable to a big server on the grass who enjoys a hot day, but the Grand Slam format allows him to ride out all but the heaviest of storms. At 34 his wiry, elastic physique shows no signs of rebelling.
