Novak Djokovic has returned to competitive action for the first time since being deported from Australia, defeating Italian teenager Lorenzo Musetti in Dubai.

Novak Djokovic has lost the opening two points in his return to tennis after his deportation from Australia.

But the world No.1 then won many more than he lost as he emerged victorious in his first competitive match of the year.

Djokovic, whose most recent match was in the Davis Cup finals in early December 2021, was facing Italian teenager Lorenzo Musetti in the first round of the Dubai Tennis Championships.

On the only previous occasion the pair met, at Roland Garros last year, Musetti took a two-set lead with successive tie-break successes.

Djokovic then won 16 of the next 17 games before an exhausted Musetti retired at 0-4 in the final set.

The 19-year-old wildcard went for his shots again, showing no fear as he went toe-to-toe with the Serbian champion.

But Djokovic was too good winning 6-3 6-3 in 73 minutes -- to advance to a meeting with Australian Alex de Minaur or Russian Karen Khachanov in the second round.

Djokovic said he was a little rusty at times but "that is to be expected",and he "very much enjoyed" being in front of a crowd again.

"It's been a while since I played the last match and I couldn't pick a better place to kick-start the season," he said in his on-court post-match interview.

"All in all it was a very pleasant experience for me."

Djokovic had been cheered onto court and had plenty of support under the lights with some spectators waving flags bearing his likeness and the slogan 'Stand with Novak'.

The five-time champion in Dubai had no problems getting into the United Arab Emirates despite being the only player in the men's top 100 unvaccinated against COVID-19.

The jab is not required for visitors to Dubai.

He was deported from Australia on January 16 on 'health and good order grounds' after a protracted legal battle with the federal government.

Djokovic said at the weekend he felt "as well-prepared as I possibly can be" and so it proved against world No.58 Musetti.

The 34-year-old Djokovic -- who last week said in a BBC he was not against vaccines but was prepared to miss major tournaments rather than receive a COVID-19 vaccination -- said he was well received by his fellow players in Dubai.

"Majority of them actually welcomed me and said it's nice to see me back on the tour," he said.

"That makes me feel great."
