**Defending champion Rafael Nadal beat Ivo Karlovic 6-4 4-6 6-4 6-4 to book a quarter-final meeting with Britain’s Andy Murray at the Australian Open.**Second seed Nadal rallied after losing the second set to claim a commanding victory over the 6ft 10ins Karlovic.
The Spaniard has won seven of his nine matches against Murray, who overcame John Isner and is yet to drop a set.
Nadal beat Roger Federer in the 2009 final at Melbourne Park to claim his sixth Grand Slam title.
“This has given me a lot of confidence and it will be a very difficult match against Andy Murray,” said world number two Nadal.
"He’s one of the more talented players on the tour. He can play aggressive, play offensive.
“I will try to play aggressive and play behind the line but if I don’t do that then I will have a flight home.”
