As fun as it is to see Ivanovic play with freedom, I have always admired Wozniacki for punching so much above her weight. She has no power, not a good serve m, no punchy shots, no net game, mediocre player overall. But sheer tenacity and hustle that got her even this far.
Last match of Wozniacki in top 5 of rankings for a long time. She lost points for the title in 2011 and got kicked out of top5 by Radwanska and Stosur.
wozniacki shouldn't play tennis at the very start if she will not play very aggressive and not putting an efforts on her shots. she's just a pusher and her game is very boring to be honest.
She was #1 in the world more than once, won a grand slam (AO), and has an outstanding career match record. You may not like her game, but she’s a hall of fame player for sure.
