Antonín Růsek

Antonín Růsek is a product of the FC Zbrojovka Brno academy, where he progressed through every youth category before breaking into the first team in 2016. He went on to make 83 league appearances for the club, scoring 22 goals, with a spell away on loan at 1. SC Znojmo in the Czech 2. Liga, where he added five goals in 14 matches before returning to Brno in January 2018.

In July 2021, Sigma Olomouc paid around €500,000 to bring Růsek in, making 77 league appearances and scoring 14 goals during his time at the club. His form led to recognition at international level, where he worked his way up through the Czech youth ranks, from the under-16s through to the under-21s. That progression culminated in a senior call-up, and he made his debut for the Czech Republic on 7 September 2020, coming on as a substitute in the 80th minute of a 1–2 defeat to Scotland. He has since earned three caps for the senior national team.

In September 2025, Sigma sent Růsek out on loan to FK Jablonec for the season, an arrangement without an option to buy and with a break clause available in the winter. The move became permanent the following summer: on 18 July 2026, Jablonec signed him outright for a fee in the region of €620,000–€650,000, with Růsek putting pen to paper on a contract running until 2029.
