Novak Djokovic issues public apology for 'meltdown' during historic Wimbledon victory

Novak Djokovic apologised to fans after admitting he suffered a "meltdown" during his latest historic Wimbledon victory.

The 39-year-old surpassed Roger Federer's record for the most men's singles wins at Wimbledon by defeating Roman Safiullin in four sets on Sunday to book his place in the quarter-finals.

The victory marked another milestone for the Serbian, who is chasing a record-extending 25th Grand Slam title and an eighth Wimbledon crown. But despite the landmark achievement, it was far from a straightforward afternoon on Centre Court.

Qualifier Safiullin, ranked world No. 132, pushed Djokovic throughout the contest and repeatedly disrupted the former world No. 1's rhythm.

Djokovic made the ideal start by breaking serve early, but Safiullin responded well to force a first-set tie-break. After Djokovic claimed the opener and looked to be in control with a 6-3 second-set win, frustration began to creep into his game during the third.

The veteran frequently gestured towards the sky after losing points and, after Safiullin broke serve, vented his anger by smashing a ball into the back of the court. The outburst was met with boos from sections of the Centre Court crowd, who were unhappy to see the underdog's impressive display overshadowed.

If anything, the incident only raised the intensity of the match. Both players produced a series of gripping rallies, with Djokovic forced to vary his tactics to regain control. Once he secured a crucial break in the fourth set, however, Safiullin had no way back as Djokovic sealed a 7-6 (8-6), 6-3, 3-6, 6-3 victory.

Reflecting on the win, Djokovic acknowledged his emotional outbursts and apologised for his behaviour.

"Another hard-fought win," he said. "Roman started very well. He was very aggressive. I didn't maybe feel as comfortable from the back of the court. I knew it was going to be a challenge staying in the rallies with him, particularly from the end where we were playing against the wind for pretty much the whole match.

"I don't get to feel inferior from the back of the court against too many players throughout my career, if I'm totally honest. Today was one of those days where I didn't want to stay in the rallies too long, to be honest, so I had to mix things up. It worked in some moments and in others it didn't. In the end, I managed to find the accuracy and precision on my first serve, which really got me out of trouble in the fourth set."

Looking ahead to Tuesday's quarter-final against Felix Auger-Aliassime, Djokovic was asked to sum up the first week of the tournament.

"Survive to thrive, that's how I feel," he said. "Hopefully, the thriving part is coming. And the outbursts as well, the meltdowns. I had a few of those today as well, I apologise."
