Celtic faced a humiliating 7-1 defeat against Borussia Dortmund in their Champions League match, marking another disappointing European outing for the Scottish champions. Despite a strong start to their season with 17 consecutive wins, they struggled against last season's finalists, who capitalized on Celtic's defensive frailties. After conceding an early penalty, Celtic briefly equalized through Daizen Maeda, but Dortmund quickly regained control, with Karim Adeyemi scoring a first-half hat-trick. The match highlighted Celtic's ongoing challenges in European competitions, with fans left questioning the team's approach and defensive capabilities. Brendan Rodgers, under pressure, has seen his side suffer multiple heavy defeats in the Champions League, raising doubts about their competitiveness at this level. This defeat adds to a troubling trend for Celtic, who have yet to secure a win on German soil in 14 attempts.
