Martin O'Neill has publicly challenged Celtic to demonstrate genuine "character" in their upcoming clash with Falkirk after the club suffered a disastrous exit from the Champions League play‑offs at the hands of Austrian side LASK. The Scottish champions entered the second leg with a comfortable 3‑0 advantage secured in Glasgow, a lead that was further bolstered when captain Callum McGregor struck a deflected goal just 21 minutes into the match in Austria.

What seemed like a straightforward path to the group stage quickly unraveled as LASK mounted a dramatic comeback, eventually prevailing 5‑4 on aggregate after extra‑time. The result relegated Celtic to the Europa League, a competition that offers less prestige and significantly lower financial rewards. O'Neill, who previously managed Celtic on a permanent basis from 2000 to 2005 and guided the club to a league title and a Scottish Cup triumph last season, is acutely aware that the disappointment still reverberates among the Hoops faithful. He warned that supporters will be looking for an immediate and decisive response when Celtic face the Bairns on Saturday.

"From my experience at this club, you are never more than one game away from a crisis, and that is exactly where we find ourselves now," the 74‑year‑old manager said, adding that McGregor is expected to be available despite missing recent training sessions due to a stomach bug. The manager reflected on the nature of the loss, describing it as a "major disappointment" to be eliminated after holding a clear lead and appearing to control the game for the majority of the match.

He acknowledged that LASK had a few moments of contention, but insisted Celtic had created the better chances overall. "To let it slip in the way it did is my responsibility," O'Neill admitted.

He emphasized the need for the squad to exhibit resilience, using a term he recognized as over‑used but nonetheless essential: character. "We have to show a lot of character," he said, warning that the upcoming game will likely feature errant passes, defensive lapses, and perhaps even an early goal against them that could test the patience of the crowd. "The supporters will get restless, and we must fight that," O'Neill added.

Drawing on his long tenure in Scottish football, O'Neill compared the current situation to challenges faced under former Celtic figures such as Henrik Larsson, Neil Lennon, and Paul Lambert. "The expectations don’t change, and we cannot rest on our laurels," he noted. He reflected on the highs of the previous season, calling it "fantastic" and one of the great moments in his career, while also acknowledging the low of the recent defeat.

"At 74, the pressure doesn’t ease – it actually intensifies," he remarked. Looking ahead, Celtic's Europa League draw places them against a formidable array of opponents: away fixtures at Benfica, Union SG, Omonia and Torreense, and home ties against Marseille, Ferencvaros, Celta Vigo and Besiktas. O'Neill expressed a mixture of excitement and realism about these upcoming challenges. "It’s tough, I’m still processing Tuesday’s loss, but there are some massive games on the horizon," he said, pulling a list of fixtures from his pocket and highlighting Marseille and Benfica as particularly noteworthy, though he admitted he hadn’t read beyond those two.

He stressed that the focus must remain on moving past the disappointment of the Champions League exit. "Tuesday was a real let‑down.

We have to try and get over it," O'Neill concluded, urging his players and supporters alike to channel their frustration into determination for the next match and the European campaign that follows. In summary, O'Neill’s message to Celtic is clear: recover quickly, display the resilience expected of a club of Celtic’s stature, and approach the Europa League fixtures with renewed vigor. The upcoming game against Falkirk offers a chance to restore confidence, appease an aggrieved fanbase, and set a positive tone for the challenges that lie ahead in continental competition.
