Petko is just a ballbasher who talks a lot but doesnt have the chops to back it up,remember 2009 she said all the players from the past generation will be gone in two years ...2011.She went on to have to have a slump and Schiavone,Na li,Stosur and Serena went on to win slams and gold medals...hopeful she keeps her mouth in check and just play tennis.
She did a dance after beating pova...brought bad karma on herself,hopefully she learned her lesson and just focus on winning and not trying too hard to be the most popular girl on tour.
