US Open LIVE: Sinner accused of using dirty tactics as Djokovic makes retirement decision

Emma Raducanu pulled out of Team GB ahead of the BJK Cup finals later this month.

The Brit will instead travel to Asia to compete in the Korea Open, a WTA 500 event.

An LTA statement read: "Of course we are disappointed. However, we believe we have a great team and we're looking forward to competing in Shenzhen."

Carlos Alcaraz has revealed he received advice from Roger Federer regarding the longevity of his career.

The Spaniard said: "One person once told me you don’t have to think about 35, 38 years old, still playing at that age. He told me: 'you have to be focused on the next five years' – from now until when I’m 27.

"Then when I get to 27, think about the next five years more. So it’s not about thinking in 15 or 20 years. It’s just about going year by year, or thinking about five years maximum.

"We’ll see until what age. I’ll try to take care of my body as well as I can now, just to have a lot of years to go."

Rafael Nadal feels Carlos Alcaraz has more "magic" than Jannik Sinner - but warned the Spaniard makes too many mistakes.

"Carlos is more magic, he’s more unpredictable, he can play at a level that probably sometimes Jannik cannot," Nadal told the Athletic.

"But at the same time, he’s making more mistakes, too - he can play better, but he can play worse, and it’s about finding the balance. Carlos has all the shots, sometimes he’s making mistakes, but he’s going for the shots and it’s more amazing to see because at the end it’s more unexpected and unpredictable."

Felix Auger-Aliassime is not getting carried away with reaching the second Grand Slam semi-final of his career.

The Canadian is keeping his feet on the ground after going toe-to-toe with Jannik Sinner.

"Future will tell. Future will tell," said Auger-Aliassime.

"I don't want to make too many predictions. Tonight I just want to take a moment to soak in the tournament and everything that was good.

"You obviously build your future with what's good in you and then you try to improve a little bit step by step. So I'm just trying to take that all in. But to say how close my level is, I mean, yeah, we were fighting out there.

"We had some good points. I was going toe to toe at times, some sets dominating. So, of course, I feel, you know, competitive, but future will tell, you know, how close I am."

Model Brooks Nader jetted into New York to watch Jannik Sinner yesterday as rumours of their romance continue to swirl.

Nader previously dated Mick Schumacher - son of legendary F1 driver Michael Schumacher.

According to Italian newspaper Corriere dello Sport, Roberto and Nicoletta Stampfl, owners of an ice cream shop in Monte Carlo, have confirmed the couples relationship.

Ms Stampfl said: "Sinner and Laila live in the La Condamine neighborhood of Monte Carlo. Our shop is under their building. I really liked Laila, she's kind, just like Jannik.

"She's beautiful, very simple in the way she carries herself and dresses. In short, she's a very down-to-earth girl.

"Sinner knows [a lot] about [ice cream] when he comes here, he tastes before deciding. But in the end, he always chooses pistachio and black cherry, his favourite."

Jannik Sinner says his medical timeout following the second set in his semi-final is nothing to worry about.

"Yeah, I just felt a small twitching after a serve when I served there in the second set on 4-3. After the treatment, was feeling much, much better," the Italian explained.

"At some point I didn't feel anything anymore. I was serving back to normal pace, so it was all good. Nothing to worry about.

"But I preferred to go off court because it's on a different spot. So it's all good."

Carlos Alcaraz is glad that US President Donald Trump will attending his final tomorrow night.

The Spaniard said: "I think that it is a privilege for the tournaments having the president from every country just to support the tournament, to support tennis, and to support the match.

"For me, playing in front of him … I will try not to think about it.

"I don’t want myself to be nervous because of it, but I think attending the tennis match, it’s great for tennis to have the president at the final. But on Sunday, my job is to play my best tennis and not let anything else get in the way."

Tim Henman thinks next year may be Novak Djokovic's final season as a professional tennis player.

"I think he will give it one more year at the Australian Open," Henman told Sky Sports "That’s where he’s had his greatest success. So I think he will have one more attempt down there. But maybe he doesn’t even know at this stage.

"It was a brilliant performance from Alcaraz. Spare a thought for Novak, those first two sets so close but Alcaraz was able to come up with the answers and find solutions.

"Novak faded fast but it’s another incredible performance from a 38-year-old to make four Grand Slam semi-finals. It was a step too far as it has been all year."

Novak Djokovic feels his level is inferior to the two new stars of men's tennis - Jannik Sinner and Carlos Alcaraz.

"I lost three out of four Slams in semis against these guys, so they're just too good, you know, playing on a really high level," he said.

"Unfortunately, I ran out of gas after the second set. I think I had enough energy to battle him and to keep up with his rhythm for two sets. After that I was gassed out, and he kept going."

Novak Djokovic, 38, is refusing to retire and vows to play every Grand Slam again next season.

The Serb is hunting his 25th Major, despite struggling to reach the level of Carlos Alcaraz or Jannik Sinner.

"I'm not giving up on Grand Slams, I'm going to continue fighting," Djokovic said.

"I still want to play a full Grand Slam season next year. They are just different from any other tournament. They are the pillars of our sport."
