However, following a disappointing second-round exit at the Australian Open, Raducanu opted to end her working relationship with the Spanish coach.

Since her remarkable triumph at Flushing Meadows nearly five years ago, the British No 1 has battled inconsistent performances and multiple injury setbacks, including wrist surgery, and remains in pursuit of her second career title.

Raducanu’s 2026 campaign got off to a difficult start, with Maria Sakkari defeating her at the United Cup.

She then fell at the third-round stage of the Hobart International.

Her Australian Open challenge proved equally frustrating, as she was knocked out in just the second round. It was this latest Grand Slam setback that prompted her decision to part ways with Roig.

There have, however, been encouraging signs since the split.

Although she suffered a first-round defeat at the Dubai Open, the British player showed improved form at the Winners Open in Romania a fortnight ago.

She progressed through the draw to reach the final, where she was beaten 6-0 6-2 by home favourite Sorana Cirstea.

Speaking on his podcast, Off Court with Greg, Rusedski drew parallels between Raducanu’s current situation and a transformative period in Roger Federer’s career.

“I remember Roger Federer going through a period by himself without a coach, and it was possibly the best thing for him,” Rusedski said.

“He figured out certain things for himself and took ownership of it.”

The Swiss legend ended his partnership with coach Peter Lundgren in 2003 and spent much of the following year without a replacement.

That coachless stretch proved remarkably productive, with Federer capturing three major titles: the US Open, Wimbledon and the Australian Open.

Rusedski believes Raducanu’s Transylvania run demonstrates she possesses the capability to develop her game independently.

“We saw her [Raducanu] in Romania get to the finals. Yes, she did not perform as well as she would like in the finals,” the former Grand Slam finalist added.

Rusedski emphasised that the British player needs to establish clarity about her playing style and technical approach before committing to another coaching partnership.

He suggested that working with a hitting partner rather than a full-time coach could prove beneficial in the interim.

“A little bit of time away without a coach right now, someone who is just hitting her, might be a real positive until she finds someone who she is on the same page with week in and week out, because she has not found that person yet. Hopefully she does,” Rusedski concluded.
