Wozniacki has magnificent shotmaking if you ask me, but it's not the power kind of one. She has to rely on all court tactics to make effective her sweet topspin mix, while still able to hit pretty decent winners when she feels them, especially with the backhand. Despite not making many winners, she's still an agressive baseliner, and she doesn't only win matches by waiting the opponent's mistake, though she can do that at times also.
Li Na against Muguruza hit two framed BH in the stands to her side pretty funny ones
In my native language they say:
