Questions were raised whether a more circumspect Djokovic might struggle to keep that spark ignited.
While far from his most glittering performances, he came through when it mattered – winning ugly, as it is dubbed, a trait the best in the business are fortunate to possess as their fallback.
“I had to accept it and move on. Of course, it was a shock for me and a lot of people,” Djokovic said of the US Open on Saturday. “But that's life, that's sport. These things can happen… I won the tournament in Rome just a week later after what happened in New York.
“I did not feel any kind of emotional disturbance or difficulty to actually be able to play or still express my emotions in whatever way… I have flaws as everybody else. Regardless of the amount of years and experience that I have on the tour, these things can still happen.
“I don't think significantly it does impact me that I'm unable now to show the fist pump or scream or something like that. It has happened in Rome already and everything is fine. I'm back to normal.”
