Novak Djokovic gives two-word response after shock defeat to world No.204 amid brutal scenes

Novak Djokovic declined to discuss his injury concerns or future plans following an unexpected defeat to Valentin Vacherot at the Shanghai Masters. The 38-year-old was visibly struggling physically and summoned the physio on several occasions for what looked like a hip problem.

Despite his discomfort, he continued playing, and world No. 204 Vacherot - who had battled through qualifying to make the main draw in Shanghai - produced the tournament's biggest shock by defeating the four-time former champion 6-3 6-4.

Djokovic is due to take part in the Six Kings Slam, an exhibition tournament in Saudi Arabia scheduled for October 15, 16, and 18. As the holder of the most Grand Slam titles, he will receive a bye straight into the semi-finals.

However, it remains unclear whether the Serbian icon will still travel to Riyadh following his latest setback against Vacherot on Saturday.

When questioned about his intentions to compete in the Six Kings Slam, Djokovic instead chose to praise his opponent. "I want to congratulate Valentin for reaching his first Masters final. Going from qualifications, it's an amazing story," the No. 4 seed in Shanghai said.

"I told him at the net that he's had an amazing tournament, but more so his attitude is very good, and his game was amazing as well.

"So it's all about him. I wish him all the best in the finals, and the better player won today."

The 38-year-old also refused to address his physical state. When pressed, he simply responded: "No. Next question, please."

Djokovic shared a warm embrace with Vacherot following the match, as the Monegasque qualifierkept his celebrations muted out of respect for the Serbian's struggles.

Despite Vacherot's limited experience competing at the elite level of tennis, Djokovic was familiar with the world No. 204 and his abilities, having encountered Vacherot and his half-brother and coach, Benjamin Balleret, at the Monte-Carlo Country Club.

Speaking ahead of Saturday's clash with Vacherot, Djokovic said: "I've known him for last couple of years. Obviously he's ranked before this tournament 200-plus. He's been around.

"He's playing for Monaco, which is a really great success, the biggest historical success for Monaco. It's amazing. So everyone is excited there. We know we have one of the nicest and biggest tournaments in our sport there in Monaco.

"So I'm glad for him, for his team. Benjamin Balleret is someone I've known for many years from Monaco, because being based there for 15 years, training at the Monte-Carlo Country Club.

"He's been improving a lot. We always knew that he's got a great potential, with a big serve, a big game, he's a big guy."
