I think the problem with this new generation of WTA players is their games just aren't solid enough to challenge Serena consistently. Serena has a few goals still she wants to tie Chris Evert and Martina Navratilova at 18 slams. But after that, I don't really see Serena hanging around much longer. Serena has accomplished everything she's wanted to do in her career she is incredibly wealthy and rich. It is kind of sad to say this, but the younger women on the WTA Tour are pathetic. Why don't the young ladies not work harder on their games? I wonder if Serena is going to get bored? Serena has no competition until Victoria Azarenka and the rest of the top women actually prove they can beat her at the slams. Sloane Stephens has the game to beat Serena BUT the girl is just not disciplined enough.
