Caroline Wozniacki is suffering an obvious slump of form and now we know that the reason is most probably that she is no longer being coached by her father, Piotr. He is not her main coach any more, but he shows up as a supplementary coach when needed. In an interview for a Danish media outlet Ekstra Bladet, Piotr didn't want to reveal the name of Caroline's new head coach.
The father-daughter cooperation ended after Wimbledon. The reason behind it could be that Caroline is trying to change her overly defensive style of play and add more aggression. Of course, her father will stay by her side, it's just that he will be less present as a coach.
This piece of news is still fresh, we will surely get more details soon. (photo by our reader Tony)
