Jakub Kaluzinski, born on 31 October 2002 (age 23), is a Polish central defensive midfielder with Istanbul Basaksehir. He made his name in Poland with Lechia Gdansk, where his senior career began to take shape in a role built more on structure than spectacle.
His most productive league season came in 2021-2022 at Lechia, when he scored once in 18 appearances. That tells its own story: he has generally been used as a holding player rather than a midfielder asked to decorate matches.
Kaluzinski is now with Istanbul Basaksehir. In 2026-2027, he has made six Süper Lig appearances, while his wider record for the club stands at nine appearances and one goal across competitions. He has also scored once in three UEFA under-21 qualifying appearances.
His career so far has moved from Lechia Gdansk to Turkey, with steady senior football and under-21 international involvement. At 23, he remains a developing midfielder rather than a finished article.
