After suffering a narrow first-leg defeat (2-1) in the Czech Republic last week, Paulo Fonseca’s squad faces a must-win scenario. Lyon must secure at least a two-goal margin to progress without facing extra time—or risk an early exit from European competition.

The UEFA’s decision to appoint Marciniak underscores the significance of the tie. At 45, the Polish referee brings unmatched experience to Décines-Charpieu, having previously officiated the 2022 FIFA World Cup final. His reputation as one of Europe’s most respected officials precedes him, with a track record in continental tournaments that demands respect.

Lyon’s mixed history with the referee

For Olympique Lyonnais supporters, Marciniak’s appointment carries emotional weight. This marks the fifth time he has officiated matches involving the club. While his most recent involvement ended in a painful 5-1 loss at Camp Nou in 2019, he also played a pivotal role in Lyon’s thrilling—but ultimately insufficient—3-1 Europa League victory over Ajax Amsterdam in 2017. The Polish official has also presided over narrow defeats against Juventus (0-1, 2016) and Viktoria Plzeň (2-1, 2014).
