Celtic suffered a humiliating 7-1 defeat against Borussia Dortmund in the UEFA Champions League, marking their 15th unsuccessful attempt to secure a win on German soil. The match began with Emre Can converting a penalty, but Celtic briefly equalized through Daizen Maeda before Karim Adeyemi's first-half hat-trick extended Dortmund's lead. Peter Schmeichel, father of Celtic goalkeeper Kasper Schmeichel, expressed his concern and frustration watching his son concede seven goals during the match. He advised Kasper to treat the loss as a 'bad day at the office' and to help his teammates recover. Despite the scoreline, Kasper made several saves that prevented an even worse outcome for the team. This defeat adds to a troubling trend for Celtic, who have faced similar thrashings from top European clubs in recent years.
