Chelsea manager Thomas Tuchel has reportedly separated from his wife of 13 years.
Tuchel's wife Sissi is believed to have started divorce proceedings last week, yet they both want an amicable split.
Sissi moved to the UK last August - around seven months after Tuchel was appointed by the Blues - and stayed in a hotel before they bought a family home in Cobham, Surrey. Chelsea's training ground is located in the area.
"Sissi and Thomas have tried to avoid splitting but in the end, there was no other way," a source told the Mail on Sunday. "It is very sad and now it is all about making sure their daughters are the top priority. Papers were lodged last week to get the divorce underway."
Tuchel and Sissi married in 2009 and have two daughters together. Sissi was seen hugging her husband at the Estadio do Dragao in Porto last May after Chelsea defeated Manchester City in the Champions League final, the crowning moment of Tuchel's career.
It's not been a great 24 hours for Tuchel. Chelsea suffered a humiliating 4-1 home defeat to west London rivals Brentford on Saturday afternoon, with former Tottenham playmaker Christian Eriksen inspiring the Bees to a famous Premier League victory.

"Nobody saw it coming, especially after going 1-0 ahead," Tuchel told BBC Sport at full-time. "It was very untypical of us. But we stopped defending. We were not aware of enough of the danger, were sloppy with the defending and got punished.
"They made the most of it in those 10 minutes. Right after their third goal we had 10 minutes where we had big, big chances and we missed them. They were lucky and clinical enough to get three goals. We did not defend like it is needed to in the Premier League and got punished."
Saturday's result hasn't derailed Chelsea's campaign, as they remain third in the Premier League - eight points clear of Tottenham in fifth. The Blues have already won two trophies this term - the UEFA Super Cup and Club World Cup - and lost the EFL Cup final.
Chelsea have reached the semi-finals of the FA Cup - where they'll face Crystal Palace at Wembley later this month - and the quarter-finals of the Champions League. The defending champions will take on Real Madrid, with the first leg in London on Wednesday.
Tuchel has received praise in recent weeks for his handling of Chelsea's ownership crisis. The Blues are currently operating under a special license - severely limiting their revenue streams - after owner Roman Abramovich was sanctioned by the UK government.
The Russian oligarch is alleged to have ties with Vladimir Putin, something he denies. Russia are currently waging a violent and unprovoked war in Ukraine. Chelsea are up for sale as a result of the crisis, with four parties closing in on a multi-billion-pound deal.
