2026 FIFA世界盃第二場比賽,由A組的南韓對上捷克,兩隊首次在世界盃賽場上相遇,這是捷克睽違20年再闖世界盃,而南韓上屆到16強止步。最終南韓2:1逆轉勝捷克,拿下A組首場的勝利。
上半場亞洲一哥、南韓隊長孫興慜多次嘗試進攻未果,捷克則先採取保守攻勢,雙方僵持0:0;下半場第59分鐘,捷克隊Vladimir Coufal使用「手榴彈」戰術,直接將球擲向禁區內,接著隊長Ladislav Krejci跳起來,成功把球頭槌入網,捷克隊率先破蛋得1分。
但南韓隊不干示弱,第67分鐘黃仁範甩開防守和門將,成功破網,捷克隊一度想救卻無力挽回,雙方來到1:1。
第78分鐘,捷克隊自由球進球,卻被判定越位,進球無效;第80分鐘南韓隊攻勢再起,替補上場的吳賢揆接應隊友傳球,輕鬆破門,南韓隊再獲1分,比數來到2:1。傷停補時結束,最終比數2:1,南韓隊獲勝,在小組賽搶下首勝。
