While Rafael Nadal is currently ranked ninth in the world, Grigor Dimitrov is ranked 15th.

In their previous eight meetings, Dimitrov has only beaten Nadal once and that was in their most recent meeting in Beijing two months ago.

Nadal defeated Alexander Zverev, Gael Monfils and Milos Raonic and is just one step away from his fourth Australian final.

Dimitrov, five years younger than Nadal, was once hailed as a future champion and nicknamed 'Baby Fed' owing to his Roger Federer-style court movement and single-handed backhand.

Now under Murray's former coach Daniel Vallverdu, Dimitrov is unbeaten in 2017, winning his fifth career title in Brisbane and now on a run of 10 matches without defeat.

Ahead of the semi-final, Dimitrov defeated David Goffin, wild card Denis Istomin and Richard Gasquet.
