You can tell Maria loathes talking about Serena or even hearing her name mentioned. She always seems to be fidgety or have a nervous laugh when she's forced to compliment her.
That's why it continues to sadden me that this matchup has been so ugly and one-sided for nearly a decade. The two biggest global icons in women's sports who happen to have a healthy dislike of each other. It could have been one of the all-time great rivalries in sports history if Maria was on her level. The WTA's version of Federer/Nadal.
