The 2019–20 UEFA Champions League quarter-final match between Barcelona and Bayern Munich was played on 14 August 2020 at the Estádio da Luz in Lisbon, Portugal.

This was also only the second occasion in history that Barcelona conceded more than 4 goals in one game in European competitions since their 5–4 loss to Levski Sofia in the 1975–76 UEFA Cup quarter-final.

Each time the eventual winner of the Bayern-Barcelona knockout tie went on not only to win the UEFA Champions League, but also complete the continental treble, which also occurred in 2009, 2013 and 2015.

Shortly after, David Alaba sliced a cross from Jordi Alba into his own net – with an unsuccessful save attempt from Manuel Neuer – to level the scores.

In the 57th minute, a neat turn and finish from the centre of the box to the bottom-right corner by Suárez gave the Spanish side a glimmer of hope, but that proved premature, as Kimmich's side-footed finish in the 63rd minute, connecting with a delivery from Alphonso Davies – who had beaten his marker, Nélson Semedo, at the edge of the box – made the scoreline 5–2 to the Germans.

Then Coutinho, who was on loan to Bayern from Barcelona, made the scoreline 8–2 in the final moments of the match: first by taking advantage of a pass from Müller in the 85th minute with a right-footed shot from the centre of the box to the bottom-left corner, followed by a left-footed shot from very close range to the bottom-left corner from a headed pass by substitute Lucas Hernandez in the 89th minute.

Barcelona suffered their heaviest loss in 69 years; this was the first time they had conceded more than five goals in a UEFA Champions League game, and their worst concession since the 8–0 defeat to Sevilla in the round of 16 of the 1946 Copa del Generalísimo.

[25] Bayern Munich, on the other hand, continued their run of winning all UEFA Champions League matches they played in the season, and would go on to lift the title.

"[39] Although Messi ended up staying in the summer, the defeat proved to be the final involvement that Ivan Rakitić, Nélson Semedo, Luis Suárez and Arturo Vidal would have with the club, as all four players departed Barcelona during the following transfer window.

[42] Marca pointed that Barcelona's relegation to the Europa League was the culmination of "a glorious cycle that was coming to an end," after the team had suffered a total of ten losses by at least a three-goal margin since 2017, calling the 2–8 defeat to Bayern "the worst.
