The Hoops had been crushed 6-0 by Atleti in the UEFA Champions League group stage game in Spain after going down to 10 men, while the Dons exited the UEFA Europa Conference League despite an impressive 2-2 draw with PAOK in Greece.

Back in the safer environs of Scotland, Korea Republic forward Yang Hyun-jun scored his first Celtic goal in the ninth minute before Japan striker Kyogo Furuhashi added a second seven minutes later in an utterly dominant first half.

Winger Luis Palma scored from the spot in the 77th minute and substitutes David Turnbull and Oh Hyeon-gyu, twice, notched in 10 minutes of added time to complete a comprehensive win for Brendan Rodgers’ side.

Rangers had won 2-0 at Livingston earlier in the day to put some pressure on Celtic but a one-sided victory restored its eight-point lead over the Old Firm rival going into the international break, albeit the Light Blues have a game in hand.
