Novak Djokovic says he is 'not an IT expert' as questions remain over positive Covid test

Novak Djokovic failed to provide any further clarity over the questions surrounding the positive Covid-19 test which gained him an exemption to travel to the Australian Open last month, despite being unvaccinated.

On Monday the world No 1 will play his first match since his disastrous trip to Melbourne, which saw him blocked from defending his Australian Open title when his visa was revoked on account of his unvaccinated status. 

There remain doubts over the timing of his December 16 positive PCR test, with reports pointing to an apparent discrepancy with the serial number attached to his result, suggesting his test might have been taken later in December. 

When speaking ahead of his opener at the Dubai Duty Free Championships, his first match since December 3, Djokovic doubled down on his insistence that there was nothing more to say about the matter.

"I understand [why people have questions]," he said on Sunday night, in his first press conference since the Australia saga. "I've seen that media has been speculating about the validity of the tests. What I can tell you is what I told Amol with the BBC. I'm not an IT expert. I have done in the last two years, as probably anybody else on the tour, so many PCR tests, rapid antigenic tests. I'm not in a position to understand how these tests are being processed and registered. I'm glad that Institute For Public Health in Serbia has come out publicly and validated those tests. That's all I can say really. I'm not in a position, neither I'm an expert, to go more into detail."

A BBC report last month suggested Djokovic's positive Covid-19 test's unique confirmation code, which was delivered by the Institute of Public Health of Serbia, was out of sequence with other tests taken
