I apologize for the inconvenience, but I don’t have the specific UEFA Europa League fixtures for the 2021 season as my information was last updated in January 2022. The schedule for UEFA competitions, including the Europa League, is subject to change based on the progress of the tournament.
For the most accurate and up-to-date information about the UEFA Europa League fixtures in 2021, including dates, matchups, and venues, I recommend checking the official UEFA website or referring to reputable sports news sources that provide real-time updates and coverage of the competition.
