The Spaniard, champion here last year, had been complaining about the vocal and fiercely partisan crowd on Court Suzanne Lenglen during her match against France's Mladenovic when she was overcome by emotion. "The crowd today was a little bit tough on me, but I understand. I just think that they were a little bit disrespectful of my game," she said.

Muguruza even yelled at a ball-kid during the match.

Muguruza, who lost 6-1 3-6 6-3, came back after a minute and said she would take any question. "We're here for the good and for the bad," she explained. "I love this tournament, no matter what happens." Asked again about the French crowd's behaviour, she said: "Let's say I understand."
