Nine-time Rome victor Rafael Nadal will make his return to competition later on Wednesday after a six-month hiatus linked to the coronavirus pandemic.
Nadal had not played a match since winning a title in Acapulco, Mexico, in February - having decided not to play the US Open over travel concerns amid the coronavirus pandemic.
The four-time Rome victor was speaking for the first time since his dramatic last 16 default in NY after he accidently struck a line judge with a ball hit in frustration.
Djokovic said he had exchanged greetings with Nadal in Rome but was yet to chat with the Spaniard about the PTPA.
He said: "Of course as anybody else I'm working mentally and emotionally as hard as I'm working physically, trying to be the best version of myself on the court and off the court".
"But for me, at least, today was a very positive comeback".
Dominic Thiem, on Sunday night in NY, closed the title match at the US Open to win his first Grand Slam and, Like Rafa Nadal on big occasions, he stretched out on the floor on his back and covered his face with his hands.
Nadal played down expectations for his return to the match court, saying: "It's obvious that to feel you're 100 per cent that you need matches".
Gauff said she had good results on clay as a junior and noted that she spends a lot of time on the surface at the French academy run by Patrick Mouratoglu, Serena Williams' coach.
Novak Djokovic behaved better Wednesday in his first match since being defaulted from the U.S. Open.
ARM founder: $40bn sale of United Kingdom chipmaker to Nvidia 'disaster'
Nvidia will spend $21.5 billion on stock purchases, and ARM employees will receive Nvidia shares worth $1.5 billion. Arm, meanwhile, will get even more support for R&D efforts as well as access to NVIDIA's entire suite of products.
"It was very, very quiet, which is very unusual to what we are used to here in Rome, which has one of the loudest and most energetic crowd atmospheres on the tour. But there was somebody in the corridor of the stadium that was talking - about five, six people".
Thiem has responded to those comments, saying "When he complains about a lack of respect, and says that I owe it all to him, and seriously suggests that I would have been a futures player without him, I have to ask whether he has developed delusions of grandeur". That meant a new Grand Slam champion other than the Big Three was going to be crowned, four years after Wawrinka. "It's a little unusual".
Djokovic will face either fellow Serb Filip Krajinovic or Italian Marco Cecchinato for a place in the last-16.
"I don't know what's going on", the 34-year-old told journalists when questioned about the French Open. I had a chat with him as well privately. "I'm just very, very pleased that he's doing well". His performance on Monday's final in NY also showed his stamina, despite limping towards the end of the four-hour affair from a cramped knee as he managed to hold it together to win the match from being two sets down. Maybe he was a little bit exhausted from NY but it was a flawless start for me'. It was solid, good shots on the forehand and backhand.
"I have outbursts, and this is kind of the personality and the player that I have always been, you know", he said.
