Celtic ended Jimmy Thelin’s unbeaten start as Aberdeen boss in devastating fashion to reach the Scottish League Cup final.
Flares and fireworks before the hotly anticipated clash resulted in a 14-minute delay while the smoke slowly cleared for the VAR technology to kick in.
After a cagey start, Celtic found their stride with Cameron Carter-Vickers rising to head in the opener with Kyogo and Daizen Maeda also getting on the scoresheet before the break.
The Hoops were in no mood for another Dons comeback and Maeda added their fourth just after the restart with Nicolas Kuhn making it five before the hour.
Aberdeen, who stunned Rangers in the Premiership in midweek, had no answers as Maeda completed his hat-trick late on as their unbeaten start to the season ended spectaculary at game 17.
Brendan Rodgers’ side will face Motherwell or Rangers in the final on December 15.
