Jan Ziółkowski (born 5 June 2005, age 21) is a Polish central defender with Monza. At 6ft 4in (1.94m), he is an imposing centre-half, and his current market value is around £5m, according to Transfermarkt.
His career has been shaped above all by Legia Warsaw. Across three seasons there, he made 24 league appearances and scored once, with the 2024–25 campaign his clearest step forward: 19 league appearances and his first league goal. For a young defender, that was the spell that gave the outline of his senior career some substance.
He is now with Monza, where he has made one Coppa Italia appearance in 2026–27. He has also represented Poland this season, making two appearances in European World Cup qualifying. His career so far is a compact one: Legia provided the main body of work, Monza is the current stage, and Poland have already had a look.
