Celtic have exited the Champions League after a remarkable 5-1 defeat to LASK in Linz, Austria, on 25 August 2026. The Scottish champions had established a four-goal aggregate lead, appearing set to progress to the league stage.
Callum McGregor extended Celtic's aggregate advantage to 4-0 with a deflected strike in the 21st minute. However, LASK began their comeback when Moses Usor scored in the 32nd minute, capitalising on a loose pass. Robert Ljubicic and Samuel Adeniran then netted early in the second half, bringing LASK level on aggregate.
Florian Flecker headed home in stoppage time to force an additional 30 minutes. Adeniran delivered the decisive goal in extra time, sending Celtic into the Europa League. This marks the second year running that Celtic have missed out on the Champions League league stage.
