J. Micek

Míček came up through TJ Sokol Fryčovice before joining MFK Frýdek-Místek in 2017, where he stayed until 2021, when he moved into the Baník Ostrava academy. He made his senior bow for Baník's B side in the Chance Národní Liga in March 2025 against Tábor, and his MOL Cup debut followed that September against České Budějovice. His first-team breakthrough in the Chance Liga came against Zlín, a match Baník won 1–0 with Míček in the starting line-up. That progress was rewarded in June 2026 with a new long-term contract at Baník running to 2029.

The following season brought his first senior goal, a 45th-minute-plus strike that settled a 1–0 win over Sigma Olomouc. It came after four matches without scoring, and by then he had five Chance Liga appearances to his name.

Internationally, Míček has moved steadily up the Czech youth ranks, from the under-15s through to the under-19s. His under-17 record includes a goal against Belarus and three appearances at the 2024 European Under-17 Championship, while at under-19 level he has scored against Bosnia and Herzegovina and featured six times in qualifying for the 2026 European Under-19 Championship.
