FC Barcelona once again endured a humiliating evening in the UEFA Champions League, a recurring theme that has haunted them for nearly the past decade since their last triumph in the competition during the 2014-15 season.

Young star Lamine Yamal vowed to bounce back after Paris Saint-Germain eliminated them in the competition's quarterfinals this season on Tuesday, April 16.

"There's always payback in football; we will be back," Barcelona's youngest goalscorer said on Instagram after the game.

The Catalan giants entered the second leg of their matchup against PSG with a 3-2 lead, having notched a huge victory in Paris and an opportunity to reach the semifinals for the first time in the post-Lionel Messi era.

However, their hopes faded after PSG took a 4-1 win at the Estadi Olímpic Lluís Companys, Barcelona's temporary home while Spotify Camp Nou is being renovated.

The 16-year-old Yamal was visibly upset and crying after the final whistle.

Barcelona crumbles after Ronald Araujo's red card

Barcelona even managed to score the game's first goal, thanks to a 14th-minute strike from Raphinha, extending their aggregate lead to 4-2.

However, their advantage took a hit when center-back Ronald Araújo received a red card around the 30th minute, leaving Barcelona with ten men for the remainder of the game. Their defense crumbled, conceding four consecutive goals.

This resulted in a 6-4 aggregate defeat for the reigning La Liga champions, leading to their elimination from the Champions League.
