The 2025-26 Europa League gets fully under way this week - with the unusual format of nine matches taking place on Wednesday night. Nottingham Forest and Celtic are among the 18 teams in action on the opening night, while Aston Villa and Rangers begin their campaigns in the more traditional Thursday night slot. Much like the Champions League's return last week, the upcoming matches are part of an exclusive week for the Europa League, with no Champions League or Conference League fixtures scheduled.
