The couple moved to Denmark when Piotr signed for the Danish football club Boldklubben 1909. Her older brother, Patrik Wozniacki, is a former professional footballer in Denmark.
Playing style, coaches and sponsors
Wozniacki's playing style centres on "the defensive aspects of tennis with her anticipation, movement, agility, footwork and speed all first-rate and key parts of her game." She also anticipates serves with aggressive footwork. Her two-handed backhand is one of her best weapons as she is capable of turning defence into offence, most notably the backhand down-the-line. Her defensive playing style has her contemporaries label her a counter-puncher.
Wozniacki's father, Piotr, has been her primary coach since she was 14.
In 2009, Wozniacki signed on to become an endorser for the line of tennis apparel designed by Stella McCartney for Adidas.

Wozniacki was said to have used an expletive in referring to a linesman who made a disputed call.

In December 2012, during an exhibition match in Brazil, Wozniacki imitated friend and fellow tennis player Serena Williams by stuffing towels in her shirt and skirt in order to appear to be large-chested and have a large rear end. This act divided opinion on social network sites. It was noted that Wozniacki has done the impression before without controversy. Williams also defended Wozniacki in an email to USA Today and pointed out that they are friends and that the act was not racist. Williams added, however, that if people feel this way, then she should do something else next time.
