Musiala’s recent diagnosis is the latest setback in what has been a desperately unlucky period to his highly successful career.

His 2024-25 campaign was ended by injury in early April and, just over a week later, he was involved in a serious traffic accident.

Musiala was still able to return to action two months later to take part in the Fifa Club World Cup but then suffered a broken leg and dislocated ankle – in the quarter-final against Paris St-Germain – which ruled him out for 196 days.

The former England Under-21 international then played with a metal plate in his foot from January until the end of this summer’s World Cup in North America, where he made four appearances for Germany.

The plate was removed in July, limiting his ability to train during pre-season.

“Musiala hasn’t been much of a factor in the past 18 months,” said German football expert Constantin Eckner. “He came back for the Club World Cup but suffered a broken leg when he collided with Gianluigi Donnarumma.

“It took him months to recover from that. He just had a metal plate removed from his left foot so he played with that for half a year and had to deal with ankle issues.

“Naturally, his performances left much to be desired. The start to the upcoming season would have been difficult anyway, because he didn’t take part in team training for some time due to the surgery in which the plate was removed. Now, there’s another stumbling block.”

Eckner added Bayern’s £43m summer signing of Morocco attacking midfielder Ismael Saibari was in part to protect against Musiala’s fitness issues.

“Musiala is Bayern’s top earner alongside Harry Kane, but his contribution hasn’t been anywhere close to Kane’s,” he said. “He is still young and things can change again.

“He has a release clause in his contract that could be triggered next summer, but the fee would be in the nine digits. It is unrealistic that any club would be willing to pay that for him at the moment.”

In 2023, Kyrgios admitted assaulting ex-girlfriend Chiara Passari by pushing her on the pavement during a row in Canberra. The magistrate called the incident “a single act of stupidity or frustration” when sparing him a criminal record.

Then two years ago he publicly distanced himself from controversial influencer Andrew Tate, who is currently fighting extradition to the UK on charges including rape and offences related to sex trafficking.

Kyrgios told the BBC he had “deleted posts, unfollowed him and gone to all lengths to distance” himself from Tate.

The current world number 919 will now step away from public life for the next 28 days to “do the work and come back better.”

The legal process will take many months – and Kyrgios is no fan of tennis’ anti-doping system.

Describing the system as “awful,” he made repeatedly clear his opinion that both Jannik Sinner and Iga Swiatek received overly lenient bans after their recent high-profile doping cases.

“Sad day for tennis. Fairness in tennis does not exist,” Kyrgios wrote after Sinner accepted a three-month ban for testing positive for clostebol.

But if he does decide he wants to continue his career into his thirties, much will rest on the process of which Kyrgios has been so critical.

An English athletics coach and former gold medallist said by media reports to be missing is serving a prison sentence in Morocco, BBC Sport can reveal.

Leon Baptiste, who was coaching a clutch of top British track athletes in the run-up to this summer’s Commonwealth Games and European Championships, suddenly went off the grid more than three months ago.

Neither UK Athletics, for whom he worked as a consultant sprinting coach, nor the sprinters he coached knew why he was out of contact.

In May, Baptiste sent the group of athletes he coached a short message saying he would be absent from training “for a while”. They have been given no further explanation.

Over the weekend, he was reported in the media as being “missing” and was said to have disappeared in Morocco.

On Tuesday, a brief email was sent to the people coached by Baptiste – the 200m gold medallist at the 2010 Commonwealth Games – in which he resigned from the position, citing unspecified ill health.

A source at the Moroccan Ministry of Justice confirmed to BBC Sport that Baptiste was arrested in Marrakech in May, has subsequently been convicted and is now serving a custodial sentence in Al-Oudaya prison.

“In relation to the reports concerning the alleged ‘disappearance of Leon Baptiste’ – an English athletics coach reportedly missing in Morocco for more than two months under questionable circumstances – please note that the information published in this regard is inaccurate and does not reflect the facts of the case,” said the source.

“The foreign national concerned had not lost contact with his surroundings and was not subject to any disappearance or unexplained absence.

“He is currently being held at the local prison in Marrakech, where he is serving a custodial sentence following his conviction by the competent judicial authorities in connection with a misdemeanour case.”

They added Baptiste, 41, was “in good health”.

No details of what he was convicted of, or the length of his sentence, were provided.

The MMJ source said that was not uncommon in the Moroccan judicial system.

A spokesperson for the Morocco Public Prosecution Office confirmed: “The British national is currently being held at the local prison in Marrakech, where he is serving a custodial sentence following a court judgment against him in connection with his involvement in a criminal case.”

Asked directly about Baptiste, a UK Foreign Office spokesperson said: “We are supporting a British national who is detained in Morocco and are in contact with the authorities.”

Sources told BBC Sport that Baptiste travelled to Marrakech with three other British former athletes, who have all since returned to the UK.

BBC Sport has made attempts to contact the athletes but had no reply.

Baptiste’s family are understood to be aware of his imprisonment.
