Who Sits in Karolína Muchová’s Player’s Box?

2 min read

The saying goes that it takes a village to raise a child. But in tennis, it takes a team to make a champion. As Karolína Muchová aims to win her first Grand Slam title at Wimbledon, she’ll be cheered on not only by everyone at Centre Court, but by those closest to her as well. That support system includes her parents, her coach, and other members of her inner circle. So, here’s who we can expect to see in Karolína Muchová’s player’s box:

Sven Groeneveld began working with Muchová at the start of 2026, after she parted ways with coach Emil Mišek for the second time. It has already produced results: Muchová won her first WTA 1000 title at the Qatar Open in February, and has since reached the Wimbledon finals. Groeneveld brings more than three decades of experience coaching top-ranked players, having guided Monica Seles, Ana Ivanovic, and Maria Sharapova to Grand Slam titles, among others.

Her physiotherapist, Jaroslav Blažek

Per his LinkedIn profile, Blažek holds a bachelor’s and master’s degree in physical education and sports from Charles University in Prague, with a specialization in tennis coaching. He worked as a tennis trainer in Austria and as a fitness trainer and cross-country skiing trainer at Hotel Post Bezau before joining the professional tour. Since 2015, he has worked as a physical trainer and masseur for Swiss tennis star Belinda Bencic.

Speaking ahead of the 2023 U.S. Open, Blažek described Karolína as someone who will “fight like a lion. “First of all, Karolína, however she’s looking, is an easy-going girl. She’s a hard worker as well, and she’s realizing what’s going on,” Blažek told reporters in Flushing Meadows. “It’s like generally she’s better moving, serving, and the mindset. The self-confidence grew up. So every match, when you win, it’s kicking you up a little bit…Self-confidence and hand-by-hand, everything is getting better.”

Her parents, Josef Muchá and Hana Muchová

Muchová was born in Olomouc, Czechia, and grew up in a sporting household. Her father, Josef Muchá, is a former professional soccer player who made more than 250 appearances in the Czech First League, including over 200 for SK Sigma Olomouc. He introduced her to tennis at age seven. Josef has since moved into coaching.

Her brother, Filip Muchá

Her brother, Filip, is also a professional athlete, and followed their father into football. A goalkeeper, Filip currently plays for Czech club SK Hanácká Slavia Kroměříž and has previously had stints at FC Zbrojovka Brno and SK Prostějov. He sometimes travel for his sister’s big tournaments; Filip, for instance, shared photos of the family in Paris for the 2019 French Open.
