Emma Raducanu's coaching dilemma continues following the end of her partnership with Dmitry Tursunov.

The former US Open champion is understood to now be working alongside Jez Green, who used to be part of Andy Murray's team.

Raducanu is currently searching for her fifth tennis mentor in just 16 months.

Who is Jez Green?

Green is a physical conditioning specialist who has been working on both the ATP and WTA Tours for more than 20 years.

During his career he has worked with the likes of Tomas Berdych and Alexander Zverev, but is most known for his success with Andy Murray.

Green was part of the British star's team for seven years and played a huge role in helping him adapt to the physical demands of professional tennis.

Murray went on to win the US Open and Wimbledon, as well as Olympic gold at the 2012 London Games under Green's guidance before the pair eventually parted ways in 2014.

Murray explained the reason behind letting his conditioning coach go was simply down to the team deciding that "change would be best for all of us."

Green is currently working with former world number three Dominic Thiem but will be able to provide Raducanu with fitness advice over the coming weeks as she prepares for the 2023 Tour.

Raducanu has had a torrid experience with injuries this year and she will be prioritising her time with Green in order to boost her fitness levels.

Throughout 2022, the 19-year-old has withdrawn from five tournaments due to injury. Her latest retirement was caused by a wrist injury during the Transylvania Open — a tournament on the home soil of her Romanian father.

She also failed to make it through the semi-finals of the Korea Open in September because of pain in her glute and lower back.

Why is Emma Raducanu looking for a new coach?

Since making her WTA Tour debut in June 2021, Raducanu has been burning through her coaching options.

In April prior to her first WTA match, the Brit appointed Murray's father-in-law Nigel Sears as her coach but her time with him was short as she replaced him with Andrew Richardson just three months later.

At this time, Raducanu was at the start of her meteoric rise into the spotlight. Richardson helped her win her first Grand Slam title at the US Open, where she became the first qualifier in history to win a major tournament.

However, despite the remarkable achievement, Raducanu opted not to extend her contract with Richardson, stating she was looking for someone with more extensive WTA Tour experience to take her to the next level.

She then turned to Torben Beltz, who previously coached Angelique Kerber and helped her reach world number one status. However, this was another short working relationship and the two parted ways after just five months.

Raducanu's most recent appointment was Tursunov, who she brought in ahead of her US Open title defence last month.

Unfortunately for the Brit, her reign ended in the first round of the tournament when she was knocked out by Alizé Cornet in straight sets.

Despite her underwhelming run of form, Raducanu was reportedly keen to continue working with Tursunov, but the Russian has opted to work with another player instead.

Her focus now lies on tackling the injury issues that have hampered her 2022 season and looking to get herself back to full fitness ahead of the new year, where she will look to climb from her current world ranking of 88th.
