Atletico Madrid reached the UEFA Champions League semifinals on April 14, 2026, despite a 2-1 loss to FC Barcelona at the Estadio Riyadh Air Metropolitano in Madrid, Spain. This victory is significant as it marks the first time under coach Diego Simeone that Atletico has lost a home match in the Champions League knockout stage. Early goals from Lamine Yamal and Ferrán Torres put Barcelona ahead, but Ademola Lookman equalized for Atletico with a well-timed counterattack goal. Despite having 71% possession, Barcelona struggled to capitalize on their chances, particularly after Éric Garcia was sent off for a foul. Lookman's performance, alongside strong contributions from Matteo Ruggeri and Marcos Llorente, proved pivotal in securing Atletico's progression. The team now looks ahead to a Copa del Rey final and potential Champions League semifinal against either Arsenal or Sporting Clube de Portugal.
