Karol Krzysztof Borys (born 28 September 2006) is a Polish professional footballer who plays as a midfielder for Slovenian PrvaLiga club Maribor, on loan from Belgian Pro League club Westerlo.
Born in Otmuchów, Borys started his career with hometown club Czarni Otmuchów, before joining the à Âlàsk Wrocà Âaw academy in 2013. He signed his first professional contract there in October 2021, having previously attended a trial at Manchester United.
On 21 May 2022, Borys made his professional debut for à Âlàsk's first team, coming on as a substitute in the last 20 minutes of a 4âÂÂ3 home loss to Górnik Zabrze during the last matchday of the 2021âÂÂ22 season. By doing so, he became the first player born in 2006 to appear in Ekstraklasa and displaced Mirosà Âaw PÃÂkala as the youngest player in the history of the Silesian club.
On 11 October 2023, Borys was named by English newspaper The Guardian as one of the best players born in 2006 worldwide. In December of the same year, he reportedly attracted interest from several European clubs, including Fiorentina and PSV Eindhoven.
On 1 February 2024, Belgian club Westerlo announced the signing of Borys on a two-and-a-half-year contract. He made his debut for De Kemphanen on 31 March that year, coming on as a second-half substitute in a 2âÂÂ0 Europe play-off away loss against Sint-Truiden. After the 2023âÂÂ24 season, in which Borys made four appearances for Westerlo, he joined Slovenian PrvaLiga club Maribor on a season-long loan with the option to make the transfer permanent. He played 20 games for the club in all competitions in the first half of the season, before his season was cut short due to a serious injury. His loan at Maribor was then extended for another year in July 2025.
