Re: can we agree that Justine is the best player of the 00's
It is an interesting question.
From the beginning of the 2000s, Serena and Justine have seven Grand Slams each, provided Justine wins today. Let's just say this discussion is happening tomorrow and Justine has already won the 2007 US Open.
That leaves them even at Grand Slam singles titles. Serena has won all four, and Justine has won only three. But, it is possible that what Serena has won in Grand Slams, Justine makes up for it with the Year-End Championships and the Olympics Gold Medal. It is just up for talks.
Justine has won more overall Singles titles. She has shown onsistency at the top for longer than Serena has. She's consistently won at least one Grand Slam since 2003. Justine still doesn't have the dominance of Serena's four consecutive Grand Slams, along with Doubles, though.
