Novak Djokovic was dissatisfied with himself for losing his temper when he lost his first set of the Australian Open against Denis Shapovalov, writes Eleanor Crooks of the Press Association.

The world number one lost five games in a row from fourth to fourth win in the third set, however, responding strongly to the win 6-3, 6-4, 4-6, 6-0, thus ensuring that he after the tournament the top of the leaderboard remains.

Djokovic was unhappy that the headlights were turned on in the third set and this seemed to affect his focus. At the set-point down, he was given a code violation for cursing Referee Damien Dumusois and answering with a sarcastic thumbs-up.

"I've verbally condemned myself," was Djokovic's euphemistic description for his moment of anger.

Commenting on his overall performance, Djokovic said: "Apart from the little horror I had in the fourth set of 4-1 and 4-2, I thought I had played well, especially in the fourth set.

"I expected Denis to come out and be aggressive, he made many unforeseen mistakes, I thought, for the first one and a half.

"I just stuck in from the back of the field and served well, playing the right punches, with the first two sets just controlling everything.

It was not going to happen to me, I know better, I have experience, but it happens, I think, I allowed him to get back into the match.

"It was important to start the fourth set well, but I also like the fact that I was tested because I want to be tested, matches and opponents get tougher, I feel well, things are going well."

As far as lighting is concerned, Djokovic said: "I just had the feeling that the lighting was switched on at 5 pm, it was completely unnecessary, it was very bright.

"But the explanation I got from the supervisor was that the TV requires that, whatever the TV says, we have to respect, I think."

It was a first meeting between Djokovic and 19-year-old Canadian Shapovalov, one of the most exciting talents of the next generation.

Djokovic was impressed and said: "He has a pretty complete game, he has the big serve, a lot of rotation on the ball, he can beat him flat, he can beat it with a spin, I like his mentality, I like his confidence oneself

"Obviously he lacks experience in the big games on the big stage, but that's yet to come - these experiences can only help him."

Shapovalov said with a smile, "He's good, I think he's Number One, but I definitely had my chances, especially after the third set, I felt a bit physically dead. He started the fourth really well.

"But the first two, it was a bit difficult for me, since it's not every day that I'm playing on such a stage against such a top guy." In any case, I was a bit nervous, a bit tight with everything. "

The two exchanged warm words on the net, and Shapovalov added, "He just told me that it's a pleasure to play against me, to be honest, the joy was mine, in such an event in one Court to play a champion like him, It's a dream for me.

"During the game, I smiled and enjoyed my time out there, it was a lot of fun, and at the same time I would like to compete against these guys in the near future, it's about preparing physically for that kind of match."
