Celtic faced one of the most challenging nights in their European history at the Raiffeisen Arena as they suffered a stunning 5-4 aggregate loss to LASK after leading by four goals. Manager Martin O'Neill took full responsibility for the defeat, expressing his disappointment and reflecting on the implications of this failure.

The match shifted dramatically in the second half, with Celtic collapsing under pressure despite their initial advantage. O'Neill candidly stated, "I'm responsible for this one. Without a doubt." He compared this defeat to past disappointments, emphasizing the importance of qualifying for the Champions League, both financially and for the club's prestige.

In the aftermath, O'Neill acknowledged the challenges ahead for Celtic, particularly regarding the transfer window. He noted the adverse effects of missing out on Champions League qualification, stating, "The qualification for the Champions League is major, it's major in every aspect."

Celtic captain Callum McGregor also shared his thoughts, admitting, "We got what we deserved. We were passive all night. We looked scared to go and win the game." He stressed the collective accountability of the players, asserting that they must show resilience and bounce back following this setback.

As Celtic grapples with the fallout from this defeat, questions about the squad's readiness and the team's response to adversity loom large. The club now faces the challenge of regrouping and moving forward after a disappointing exit from the Champions League.
