Celtic's collapse in the second leg of the tie was a stark contrast to their dominant display in the first half, where they led 3-0 from the first leg in Glasgow. However, LASK's second-half bombardment ultimately led to a 5-4 aggregate defeat, with Celtic's defence crumbling under the pressure. The defeat marks a sixth consecutive failure for Celtic to qualify for the Champions League, with the club's revenue of £143m ranking them among the top 60 clubs in Europe in the 2024/25 season.

The financial consequences of Celtic's failure to make it to the Champions League this term will be significant, with football finance expert Kieran Maguire estimating the losses to be north of £20m. The club's share price has already taken a hit, with a 4-5% drop reflecting the impact on future revenues. Celtic's fans will still buy tickets, but the prices charged for corporate and hospitality packages will be significantly lower without the prestige of Champions League football.

Celtic's transfer policy has come under scrutiny, with the club having sold key players Daizen Maeda and Arne Engels to Ipswich Town and West Ham United, respectively. Former Celtic striker Chris Sutton questioned the decision to let influential players leave before such a crucial game on social media, while former captain Scott Brown believes the club's depth isn't of the level required to compete in Europe's premier club competition.

The defeat has left Celtic's manager Martin O'Neill facing questions about his team's performance, with Brown suggesting that the manager was protecting his players. O'Neill has spoken about transfer targets having to be reassessed in the wake of the defeat, and Maguire pointed out that the club will likely lose out on sponsor bonuses as well.

Celtic's next step will be to regroup and reassess their transfer targets, with the club's fans expecting a significant overhaul of the squad. The financial consequences of the defeat will be significant, but Celtic's focus will be on rebuilding and preparing for the Europa League campaign.
