During the off-season, Raducanu announced that this year she’d be working with Yutaka Nakamura – former fitness coach to the likes of Maria Sharapova and Naomi Osaka.

Having now spent several weeks working together, the British No.2 says that she’s already feeling the impact on her game and performance.

“Having him (Nakamura) in my camp has been a great addition,” she said. “He's helped me a lot just in terms of microdosing bits, the fitness here and there throughout the day, tapering, managing my loads – because I’m someone who always wants to push more, train more. Having him to adapt exercises or pull me back has been really useful.

“He’s also a really committed person and is reliable so I know every day there won’t be any major surprises coming my way. He has a lot of experience with top players so having his belief and confidence in me has helped a lot.

“I think building a body, that's a continuous process. I think it's not something that you necessarily put a timeline on. Even when you’re a top athlete there’s things you can do better.

“I do already feel a difference when I step on the court. I feel like I'm quite reactive and explosive. I think that stems from my warm-ups being not necessarily warm-ups, but they're more like a bit of a session. I feel just ready to go when I'm on the court.”

Raducanu has been dealt a difficult draw in the first round of the Australian Open as she gets set to face 26th seed Ekaterina Alexandrova.

She had also been drawn against Alexandrova in the opening round of Wimbledon last year before the 30-year-old was forced to withdraw.

While she may be seen as the underdog, Raducanu has shown time and time again that that is when she can be at her most deadly and her performances at the Billie Jean King Cup indicate that she is more than ready to go toe-to-toe with anyone in the game.

“It's a tricky draw, of course,” Raducanu admitted. “Being unseeded, you can play any top opponent. She's a player with a lot of experience. I guess I'm coming in with the underdog mentality. She's been in this situation many more times than I have.

“I back myself to the hills. I feel like I'm in a good place with how I'm approaching my tennis, how I'm feeling on the court. Actually, we were going to go through the match the morning of, and then it got cancelled at Wimbledon. I haven't gone through that yet, but I will obviously in the next few days.

“I know that whenever I play, like, any top opponent, I feel like with the way that I'm feeling on the practice court right now, I was practicing with top 10 players, feeling pretty good out there, I think I can be a dangerous opponent for anyone really. I think you have to kind of have that belief as a player. It's not really worth it going on court if you don't believe you can win.”
