Lee Kang-in hits post as Atletico Madrid falls 0-3 to Athletic Club

Atletico Madrid suffered their first defeat of the 2026-27 La Liga season, losing 0-3 to Athletic Club at San Mamés. Lee Kang-in started the match as a forward and created an early opportunity, hitting the left goalpost with a shot just three minutes after kickoff.

Despite Lee's early offensive pressure and a key pass that assisted teammate Alex Baena, Athletic Club took control of the match with two quick goals in the second half. Atletico Madrid's momentum shifted significantly between the second and fifth minutes of the second half, leading to the decisive deficit.

Following the match, Atletico Madrid manager Diego Simeone took responsibility for the loss, citing a lack of concentration and failure to provide tactical solutions during the critical two-minute window in the second half. He noted that the coaching staff failed to properly communicate necessary adjustments to the players.
