The British tennis star is in no rush to find a full-time coach and is happy to be working with Petchey - a former of coach of Andy Murray's - as she returns to the court at the Madrid Open this week.

Raducanu said: "I'm happy with the set-up going forward right now - it's been working well.

"I like him a lot and I've known him since before the US Open [victory in 2021] and it's nice to have familiar faces around."

She added: "We're keeping things informal for now and it's been working. He's someone I've known for a long time and I do feel like I can trust him.

"For now there is no real thing set in stone but we're taking it week to week and he's helping me as much as he can alongside his current commitments."

Raducanu has been without a full-time coach since January but enjoyed getting the chance to work with Petchey during her recent training block in Los Angeles.

The sports star said: "I'm happy with [the training block] and how I'm feeling on the court right now. I think I did some great work on my game and I'm looking forward to testing it on a match court.

"We created our own little bubble and it was nice to be working on my game out there but at the same time having fun and enjoying it.

"He's helped me in a lot of areas of my game and also off the court finding things to stimulate me mentally and constantly challenging me - which I like."

Raducanu will play her first match in almost a month at the Madrid Open and felt that the rest was necessary for both her body and mind.

She said: "I had a long start to the year with many weeks in a row and I think my body and brain needed to have a little recharge.

"With the transition to a different surface on clay, I feel I'm not at the point that I can switch surfaces in back-to-back weeks."
