Michael Oliver is the referee for FC Porto-Napoli

Michael Oliver will officiate the Champions League match between FC Porto and Napoli at Estádio do Dragão. This will be Oliver's third time refereeing a Porto match, having previously officiated their games in the 2022/23 and 2018/19 seasons. He will be supported by assistants Stuart Burt and James Mainwaring, with Stuart Attwell as the video assistant referee. FC Porto is currently struggling in the league, sitting in 34th place and seeking their first points after three consecutive losses. Meanwhile, UEFA has appointed Ivan Kruzliak for Sporting's match against Shakhtar Donetsk, with Tiago Fernandes temporarily taking over as coach after Rui Borges's departure.
