An erratic Novak Djokovic suffered a surprise 6-3, 4-6, 6-2 defeat against the 10th-seeded Russian Daniil Medvedev in the Monte Carlo Masters quarter-finals.
World number one Novak Djokovic was dumped out by Russia's Daniil Medvedev in the quarter-finals of the Monte Carlo Masters on Friday, losing 6-3, 4-6, 6-2.
Djokovic, twice a former champion in Monte Carlo, lost his serve five times as 10th seed Medvedev gained revenge for his last-16 defeat by the Serb at this year's Australian Open.
"This was the best match of my career, maybe not in the level of tennis but in beating the number one for the first time in my life," said Medvedev.
"It's just amazing."
Medvedev will meet another Serb, Dusan Lajovic, on Saturday for a place in the final after the latter beat Italian qualifier Lorenzo Sonego 6-4, 7-5.
For Djokovic, who won a record seventh Melbourne title in January, it marked another premature exit for the top seed after he crashed out in the early rounds at Indian Wells and Miami last month.
The player who has won the last three Grand Slam events and could conclude a personal sweep with another title at Roland Garros in June, feels that all he needs is more court time and some extra polish.
"The French Open is the ultimate goal on clay. It's expected in a way for me to peak right at that tournament, because that's what I'm aiming for.
"This is only the first tournament on clay, and it's a long season. Let's see how it goes.
"Maybe I'm lacking the consistency with the top results in the last couple of years in the best tournaments.
"But I've been playing my best at Grand Slams and that's what I intend to do."
Djokovic was broken three times in the final set, clawing one back but exiting when Medvedev drove a backhand into the far corner on match point.
The winner totalled less than half of the 47 unforced errors, which came off the Djokovic racquet in the two-hour, 20-minute struggle in windy conditions.
"Novak played worse here than the times before," Medvedev said. "But I'm also getting more experience. I'm making the top guys realise it's not easy to play me."
