Rafael Nadal was happy to see his confidence in his body play out with an emphatic win over Victor Estrella Burgos in the opening round of the Australian Open.

The world No 1 came into the tournament without having played a warm-up event following knee problems at the end of last season.

But he was anything but rusty as he raced to a 6-1 6-1 6-1 win in just an hour and 34 minutes.

Nadal said: "I always have doubts but at the same time I have the confidence that I was ready to start the tournament. That was the case.

"I'm happy for the start, of course. It's a positive start with a good result. If I do months without playing an official match it's always a little bit more difficult.

"But I started with positive feelings. That's most important thing for me now. Of course, there are things to improve. But the things that I need to improve, the matches will give me those things."

This is the 52nd grand slam of Nadal's career but the first without his long-time coach and uncle Toni Nadal in his box.

Toni announced early last season that he would cease to travel with his nephew at the end of 2017 to focus on the family's academy in Majorca.

Former world No 1 Carlos Moya has assumed the role of Nadal's main coach, and the 31-year-old Spaniard said: "Toni is the most important person in my career, everybody knows.

"I can't thank him enough for all the things. But today he is not here. He's doing a great job in my tennis academy. I have to think about the team that is here. I am happy with it."

Elsewhere, things were equally straightforward for Australian title hope Nick Kyrgios, who promised a new mature approach ahead of the tournament and largely delivered in a 6-1 6-2 6-4 victory over Rogerio Dutra Silva.

Kyrgios received a code violation for swearing at a spectator who he felt was being too noisy but otherwise kept his focus on the matter in hand.
