Serena Williams and Andy Murray may have suffered shock defeats at Wimbledon but they remained at the centre of intrigue today over the controversial and stormy manner of their exits.
Williams was a fourth-round loser in singles before she retired from her doubles second round tie with what was described as a "viral illness" after almost fainting and serving up four double faults in a performance which made for uncomfortable, almost goulish viewing.
The 32-year-old added to the mystery when she posted a photo on social media showing herself wrapped in a blanket and slumped listlessly on a sofa, staring blankly at a laptop on the table in front of her.
Her French coach, Patrick Mouratoglou, with whom she has been linked romantically, said he had not seen Serena for two days before her Court One meltdown on Tuesday where she was led by the hand from the court by sister Venus after she had struggled to maintain her balance and composure.
Former champion and world number one Martina Navratilova suggested that there was more to the story than a "viral illness" although Williams has suffered serious health issues in the past, once even having to battle life-threatening blood clots on her lungs.
"I've never seen anything like it and hopefully never will again," Navratilova told ESPN.
"It's not right. It defies logic on so many fronts. The coach said he hadn't seen her for two days. He didn't know anything. How can you be a coach and not know anything? That's wrong.
"You don't know what's going on, but virus was not it, that much is clear."
One day after defending men's champion Murray made a tame exit in straight sets to Grigor Dimitrov in the quarter-finals, the British media suggested there had been an incident involving the 27-year-old in the minutes leading up to his Centre Court clash.
