Novak Djokovic is delighted to be back in competitive action after he booked his spot in the quarter-finals of the Dubai Tennis Championships.
Djokovic, whose decision not to be vaccinated against COVID-19 caused him to be deported from Australia on the eve of the year's first grand slam, eased to a 6-3 6-3 win over Lorenzo Musetti in his first match and made similarly light work of Karen Khachanov on Wednesday.
The world number one has won in Dubai on five occasions, last doing so in 2020, having elected against defending his title last year.
However, the Serbian is looking good to regain the crown in what is his first tournament on the ATP Tour in 2022, after he was unable to feature in Melbourne.
Djokovic needed 98 minutes to see off Khachanov 6-3 7-6 (7-2) and tee up a quarter-final tie against qualifier Jiri Vesely.
"I missed it [playing competitively]. This is my life," Djokovic said, with his previous competitive appearances coming in the Davis Cup Finals in November and December.
"This is what I have known for the past 20 years. Tennis is my love. I enjoy bringing positive energy and memories for people who watch."
It was not all plain sailing for Djokovic, who offered up four break points, but the 34-year-old clawed back three of them.
"I was feeling excited and motivated," added Djokovic, who has progressed to the quarters in Dubai every time he has featured at the tournament.
"But also at the same time I was feeling stressed. Particularly at the moments when I was facing break points. I thought the atmosphere in the stadium was terrific."
Djokovic, who will lose his place at the top of the ATP rankings if Daniil Medvedev triumphs in Acapulco, should have little trouble in sealing a semi-final spot, though Vesely does come into that tie on the back of a surprise 6-2 6-4 win over world number 15 Roberto Bautista Agut, who had triumphed in Doha last week.
Murray falls short of landmark win
Second seed Andrey Rublev came from a set down to defeat Kwon Soon-woo 4-6 6-0 6-3, and will go up against American Mackenzie McDonald for a place in the last four.
There was no such joy for former world number one Andy Murray, however, who fell to Jannik Sinner 7-5 6-2.
"It is a special feeling [to share the court with Murray]," said Sinner, who will next face Hubert Hurkacz, a 6-3 6-2 winner over Alex Molcan.
"He is a legend. Winning three grand slams, many, many tournaments and he has had some unfortunate moments with surgeries. His fighting spirit is incredible.
Murray was chasing a 700th tour-level win of his career but failed to muster a single break opportunity against the Italian, who made it to the quarter-finals in Melbourne last month.
