In the darkest night of the Hansi Flick era, Barcelona fell to a humilliating 4–0 defeat against Atlético Madrid in the first leg of the Copa del Rey semifinals.
Barcelona were meticulously dismantled from the start and an own goal from Eric García plus strikes from Antoine Griezmann, Ademola Lookman and Julián Álvarez saw the Catalans go into the break trailing by four goals for the first time since the 1953–1954 season.
