Martin O'Neill has urged Celtic to demonstrate their true character against Falkirk following their shocking Champions League play-off exit to LASK. The Scottish champions initially led 3-0 from the first leg in Glasgow, with Callum McGregor's deflected shot extending their advantage in Austria.

However, a stunning collapse allowed the home side to rally back, ultimately winning 5-4 on aggregate after extra-time, which relegated Celtic to the less lucrative Europa League.

O'Neill, who previously managed Celtic from 2000-2005, acknowledged the disappointment felt by fans after losing their chance at Champions League football. He stated, "I've known this from my time at this football club, you're always one game away from a crisis, and that's the case."

Despite McGregor missing training due to a stomach bug, O'Neill remains hopeful for his availability. He reflected on the match, saying, "It's a major disappointment to get knocked out, particularly carrying a lead and with 60 minutes to go, we are looking in real control."

He emphasized the need to showcase character, explaining that challenges will arise during the match that could unsettle the crowd.

Celtic's Europa League group includes tough opponents like Benfica and Marseille. O'Neill admitted he still hasn't fully processed the disappointment of the previous match but is looking forward to the upcoming fixtures, stating, "It's something to look forward to. Some really big games there."

As Celtic prepares for their clash with Falkirk, the pressure mounts to respond positively after the heart-wrenching exit.
