"I never had a bad tournament here in Australia, I loved my first time here as a junior back in '98.
"Obviously the great memories from being here and playing some epic matches also, let's say, in Davis Cup with Lleyton (Hewitt), the finals here with Rafa, or the semi with (Marat) Safin that I lost here.
"I've had some amazing matches here. This is also where I got to world No. 1 in 2004. It's been an amazing tournament for me really."
