About this episode

Sandra Zaniewska discusses coaching Marta Kostyuk, emotions in tennis, and the pressures of competition.

Marta Kostyuk’s coach Sandra Zaniewska joins Caroline Garcia and Borja Duran on Tennis Insider Club for a deep conversation about emotions, pressure, coaching, parents, data, recovery and what it really takes to build a top tennis player. Sandra shares how she went from professional player to coach, what she learned from working with Petra Martić and Alizé Cornet, and how she built a long-term relationship with Marta Kostyuk. She explains why she loves emotional players, why the goal is not to get rid of emotions, and how Marta is learning to turn them into strength. They also discuss the pressure of winning titles, the difference between being an underdog and a top seed, why Sandra does not set ranking goals, how she uses data to measure progress, how players can recover mentally during a long WTA season, and why tennis parents need more education and support.
