SOSNOWIEC, Poland (Interstat) — RKS Rakow Częstochowa opened its UEFA Europa Conference League campaign with a 1-0 victory over Zrinjski on Thursday, defying heavy statistical odds. The match, played at ArcelorMittal Park, was decided by a goal from forward Jonatan Braut Brunes. His second-half finish, assisted by substitute Kerim Memija, secured the three points for the Polish side. The result was an upset, as analytics firm Interstat had given the visiting Bosnian club an 87.9% probability to win. Zrinjski, which saw three substitutes booked, failed to find an equalizer. The loss marks a disappointing start in Europe for Zrinjski, while Rakow Częstochowa begins group stage play with a crucial home win.
