Barcelona conceded four goals during the first half of their match against hosts Atletico Madrid, in the first leg of the Copa del Rey semi-final, in one of the most shocking games for the Catalan team.

According to statistics, Barcelona has conceded four goals in the first half only for the second time since at least the 2004/2005 season, reflecting the rarity of this scenario in the club's history over the past two decades.

The first time during the mentioned period refers to the famous match against Bayern Munich in the UEFA Champions League in 2020, when Barcelona lost 8-2 in the quarter-finals, marking one of the worst European defeats in its history.

This match brings back to the forefront questions about the strength of the Catalan team's defensive system, especially in major encounters.
