Novak Djokovic was knocked out of the Monte Carlo Masters by an inspired Dominic Thiem in the third round on Thursday, with the Austrian fifth seed progressing to a possible quarter-final with Rafael Nadal.
Thiem, a two-time French Open semi-finalist, was the better player for much of the match and won 6-7 (2/7), 6-2, 6-3 despite a battling effort from Djokovic.
The 12-time Grand Slam champion has still not reached a quarter-final since Wimbledon last July after struggling with an elbow injury.
Djokovic, 30, had said he was pain-free in Monte Carlo for the first time in two years, but Thiem backed up his French Open quarter-final win over the Serbian from last year with another impressive victory.
The 24-year-old will take on world number one Nadal in the quarter-finals.
