Grigor Dimitrov qualified for the second time in his career for a semi-final in a Grand Slam tournament.
The Bulgarian repeated his best achievement in a Grand Slam after he reached the penultimate stage of the "Wimbledon" in 2014.
In the quarterfinals of the Australian Open, world-number 15, Dimitrov defeated Belgian David Goffin 6: 3, 6: 2, 6: 4.
The winner of the match between the Spanish ninth seed in Melbourne and the Bulgarian, will play Switzerland's Roger Federer on January 29-th.
Roger Federer held off fellow countryman Stan Wawrinka to book a spot for the sixth time in the finals of the Australian Open in Melbourne.
Federer says he's looking forward to the challenge of the final.
Meanwhile, Venus and Serena Williams will meet in a Grand Slam final for the ninth time after the American sisters came through their semi-finals.
The women's final on Saturday night will be the first all-Williams final in Melbourne since 2003.
Serena says she is wary of her older sister.
