Rafael Nadal pleased with "fantastic" result

Rafael Nadal has praised his performance that resulted in him reaching the fourth round of the Australian Open.

The Spaniard stormed to a straight-sets victory over Lukas Lacko in Melbourne.

"It was a really complete match, a really solid one," said Nadal. "I'm very happy about my game. Being in the fourth round without losing a set, it's fantastic news.

"I am playing well and if you are playing well, things can be a little bit less difficult. If you are playing bad, every match will be very, very difficult.

"I have done well, played all three matches at a very good level. Friday was one of the best, solid, without mistakes, comfortable with the serve, having good returns. I played solid all match."

The former world number one has one more obstacle before he can reach the quarter-finals in Melbourne.
