The greatest grand slam winner in men's tennis history will take on the most recent when Roger Federer and Andy Murray meet in an Australian Open semi-final tonight.
US Open champion Murray and Federer - whose 17 major titles include four in Australia - will be out to book a spot in Sunday night's final against world No.1 Novak Djokovic.
They are expected to have a much tighter tussle than the Serb's 6-2 6-2 6-1 whipping of Spanish fourth seed David Ferrer on Thursday night.
While the Federer-Murray clash is an enticing main course, Friday's entrees have a strong Australian flavour.
By the time Federer and Murray take to Rod Laver Arena, four other Australians could already have become Australian Open champions and four more might have booked their place in weekend finals.
