The record for the longest away unbeaten run stands at eighteen games and is held by Bayern Munich. The run began with a 2–1 win against Celtic in the 2017–18 group stage. The streak is still ongoing, with Bayern's eighteenth and most recent away match being a 1–0 victory against Paris Saint-Germain in the 2020–21 quarter-finals. During this run, Bayern defeated Barcelona and Lyon in the 2019–20 quarter-finals and semi-finals respectively, played in Lisbon over a single leg as a result of the COVID-19 pandemic. They also defeated Paris Saint-Germain in the 2020 final. These matches, however, were played at a neutral venue, and as such are not classified as away games.
