Martina Hingis, who is now a coach at the Paris-based Patrick Mouratoglou academy, tells L’Equipe that Czech Petra Kvitova is the player who most appeals to her the most as she is "very solid, left-handed ... and is the only one I really like to watch. With others, it is monotonous. [Caroline Wozniacki] may moving better than the others, and she tries to go inside the court, but not often enough. The fact that she does not win Grand Slams is not only her problem, but also that of her coach." Wozniacki is coached by her father, Piotr, as well as the adidas Player Development staff, and she recently hired another coach, Ricardo Sanchez.

The 31-year-old Hingid added that she loves coaching and is trying to teach the young likes of Daria Gavrilova, Yulia Putintseva, Naomi Broadly and Sachia Vickery to keep moving forward.
