"I feel for him. He was clearly much better; I was on my way home tonight," Djokovic said in the on-court interview broadcast by Eurosport.
Musetti led 6–4, 6–3, 1–3 when the 23-year-old retired in his first quarterfinal at the Australian Open. The world number five had previously received medical treatment for his right leg.
To be in a quarter-final of a Grand Slam, leading 2-0 and in full control - he should have been the winner today. Without a doubt, said world number four Djokovic.
The 24-time Grand Slam winner will face the winner of the match between Jannik Sinner of Italy and Ben Shelton of the United States in the semifinals.
