Wojciech Onsorge

Wojciech Onsorge (13 April 1994 – 31 August 2026) was a Polish professional footballer who played as a centre-back.

Biography Playing career He began his career at a club in Mosina before coming through the ranks at Warta Poznań. He spent his career at Warta until February 2019, when he moved to Elana Toruń. He then went on to play half-a-season with Polonia Środa Wielkopolska in 2020 before joining Lech Poznań's reserve team on 6 February 2021. As an experienced player, his role was to help and mentor the youth and work towards a coaching licence.

Illness In June 2021, Onsorge fell gravely ill and underwent a head MRI scan; he was subsequently diagnosed with an inoperable brain tumour, specifically in the parietal lobe. In order to help fight the life-threatening situation, a fundraiser for his medical costs was started, promoted by both Poznań clubs and the people associated with them. In late 2022, he announced that his recovery was going well.

While undergoing therapy, Onsorge continued running his academy and working as a youth scout for Lech Poznań. He died on 31 August 2026, aged 32.
