"As much as she's the toughest opponent I have ever played in my life, she's my favorite person to play against," Azarenka said. "Why I still play is because I enjoy the challenges. If it's easy, if it's boring, I don't want to play."
"Yeah, I can't imagine, like Serena or Azarenka, same time play, then care about the family," she said. "I couldn't do that."
