For Aberdeen's third visit to Celtic Park this term, Barry Robson made two enforced changes from the side that beat St Mirren and clinched third place on Wednesday night. With Bojan Miovski injured and Liam Scales unable to play against his parent club, Markey Watkins and Jack MacKenzie came into the starting line-up. Dilan Markanday and Matty Kennedy were added to the bench.
After losing 4-2 at Hibs and taking one point from their last three games, Celtic made six changes for their final game ahead of next weekend's Scottish Cup final. In came Joe Hart, Alistair Johnston, Greg Taylor, Matt O'Riley, Jota and Kyogo with Scott Bain, Tony Ralston, Yuki Kobayashi, Alex Bernabei, Oh and Sead Haksabanovic missing out.
After the Dons had provided Celtic with a guard of honour ahead of the game, Kyogo was in on goal after 25 seconds, accelerating away from Angus MacDonald to collect a long pass forward, but his shot across the face of goal was wide of the target. Jota tried his luck on eight minutes following a corner but he screwed his shot through the box and wide.
Celtic enjoyed the bulk of the possession thereafter but it wasn't until 20 minutes that they worked another opportunity, Kyogo heading over the bar from a corner. A corner almost did the trick on 25, Starfelt up to power a header towards the bottom corner but Kelle Roos was down to his right to push the ball to safety.
The pressure told after 27 minutes when Kyogo gave the hosts the lead. He was given too much room to receive the ball just inside the box and then a clever turn inside earned him a shooting opportunity, making the most of that by clubbing the ball into the roof of the net.
The lead was doubled on 32 minutes, McGregor's low curling effort from 25 yards spilled by Roos and Kyogo was following in to pick up the pieces from eight yards out with a simple finish.
The Dons had a rare foray into the Celtic half on 42 minutes, Graeme Shinnie sending Marley Watkins galloping forward until Starfelt hauled him down and found himself in the referee's notebook as a result. A corner followed in the aftermath of the free-kick, Mattie Pollock winning a header at the back post, Hart scooping the ball up to save.
HALF-TIME: CELTIC 2 ABERDEEN 0
Celtic brought on Forrest for Abada at the break, the hosts nearly three up in the opening minute as MacKenzie left a back pass short, Roos out quickly to clear the ball off Kyogo's toe. Kyogo took a whack as he and Roos converged on the ball and made way for Oh after treatment.
O'Riley was next to threaten, dragging a shot against the outside of the post from 14 yards with Roos left unsighted by a ruck of players. The Dons were still just about in the game at the 52 minute mark. Shinnie was booked on the hour, grabbing hold of Hatate on halfway as Celtic looked to get away on the break. Celtic's injury problems continued three minutes later as Johnston went down for treatment before being replaced by Ralston.
Good play from Jota found Hatate in space on the edge of the area on 69 minutes but he pulled his effort wide of goal as Aberdeen clung on. Duk was replaced by Shayden Morris two minutes later.
Celtic had the ball in the net again on 75 minutes, Jota just straying offside as he ran across goal and nicked the ball away from Roos to score, the flag going up to keep things at 2-0. It was 3-0 from a Celtic corner three minutes later, a poor goal from Aberdeen's perspective, Starfelt left all alone on the edge of the six-yard box to power his header past Roos. Turnbull and Summers replaced O'Riley and Hatate in the aftermath, Ross McCrorie making way for Jayden Richardson.
It was 4-0 after 82 minutes, a curled cross from Jota finding Oh in exactly the same position as Starfelt had been and the result was precisely the same as Oh placed his header beyond Roos.
There was still time for Celtic to make it 5-0, Oh grabbing his second from close in after a Jota free-kick from 20 yards out had thudded against bar, Oh quickest to the rebound as it dropped into the six yard box.
