The Roger Federer Rafael Nadal rivalry is back on the table at the Australian Open.
Federer has set up a mouth watering semi-final against Nadal with a clinical four sets triumph over fourth seed Andy Murray.
The four-time champion is through to his 11th consecutive semi final at Melbourne Park and is brimming with confidence after injury and poor form last year.
"I am back physically and I'm explosive out there. I can get to balls. I'm not afraid to go for balls and of course last year at times you couldn't do it...but important is that I can do it now."
World number one Rafael Nadal's pleased to have won through to a 33rd meeting with Federer after struggling with his serve.
Nadal's battling a savage blister on his racquet hand, coughing up seven double-faults against Grigor Dimitrov.
"I served slower, I served bad, and I was able to win a match against a very difficult opponent so that has much more value."
Nadal has won his last four matches against Federer and leads their head to head meetings 22-10.
