An 8-year-old tennis player from Croatia, living and training in the Netherlands. He is part of the KNLTB National Selection team, trains hard every day and loves the challenge of always improving his game.
Oskar loves tennis. He looks up to Jannik Sinner and tries to bring the same focus and work ethic to every practice. His game is aggressive, he is quick around the court, and he wants to be the best mentally strong player he can be.
He is part of the KNLTB Dutch National Selection 2026/2027 and trains with JS Tennis & Coaching team.
For the 2026-2027 season, Oskar's goals are to further strengthen his shots, improve his technique, speed and agility and be the best version of himself on court. He wants to stay on top of his age in Netherlands and start competing internationally.

Oskar trains at JS Tennis & Coaching, a tennis school in Wassenaar.

Oskar's private trainer. Jade was always at the top of Dutch junior tennis and reached the final of the Dutch Championships under 16. She played professionally from 2008 until 2014, rising to world No. 755 and Dutch No. 18. She has been coaching since 2011 and in 2023 completed the highest KNLTB coaching qualification, the C-license.
Since September 2026, Oskar trains weekly at the National Training Centre (NTC) in Amstelveen under the supervision of the KNLTB, as part of the National Selection team. His trainers there are Ronald de Wind and Jade Reijndorp.
The NTC brings national-level training and club tennis together in one place. It has been home to the KNLTB office since August 2019.
Since he was 6 years old, Oskar also visits the Ljubicic Tennis Academy on the island of Lošinj in Croatia, his home country, several times a year. It is a collaboration he is very happy with.
The Ljubicic Tennis Academy is a boutique academy founded by Ivan Ljubicic, former world No. 3. Set among pine trees next to the clear Adriatic Sea, it brings together world-class coaches and tennis lovers of all ages.
Oskar is searching for a sponsor to help him keep training and competing. If you would like to be part of his team, get in touch.
