Celtic responded to Rangers closing the gap in the Scottish Premiership title race with an emphatic 6-0 rout of weary Aberdeen at Parkhead.
The Hoops - still licking their wounds following a dismal Champions League defeat to Atletico Madrid earlier in the week - were back to their clinical best against a Dons side who folded tamely in the second half.
This match was effectively over as a contest within 16 minutes after Yang Hyun-jun's header and a Kyogo Furuhashi tap-in set Brendan Rodgers' side on course to a simple victory.
Aberdeen - playing their second game in the space of 72 hours - looked somewhat jaded and were rarely seen as an attacking threat. Celtic turned on the class in the final 20 minutes with Luis Palma's penalty and further goals from substitutes David Turnbull, Oh Hyeo-gyu stoppage time double completing the rout.
This was as comfortable a victory as Celtic are likely to record this season as they eased to a ninth consecutive win over the Pittodrie club. The only minor blow for the champions was a head knock sustained by talisman Kyogo following an aerial challenge.
Here’s our Celtic player ratings from Parkhead:
Unused subs: Scott Bain (GK), Nat Phillips, Paulo Bernardo, Anthony Ralston.
9. Matt O'Riley - 8/10
Class. Didn't get on the scoresheet but should have after latching onto Kelle Roos' block. Provided an assist for Kyogo for the second goal and bossed the game. | Getty Images
10. Yang Hyun-jun - 9/10
The South Korean winger was exceptional. Grasped his big opportunity to impress Brendan Rodgers and got off the mark for his new club before slipping O'Riley through in the build-up to the second goal. Caused plenty of problems with his trickery and intelligent runs. Subbed. | Getty Images
11. Luis Palma - 9/10
The Honduran is fast developing into one of Celtic's best performers. Dangerous from dead ball scenarios and Aberdeen struggled to keep tabs on him. Crisply struck penalty and added two assists. | Getty Images
12. Kyogo Furuhashi - 8/10
One of the Japanese forward's best displays in the league this season. Produced another classy finish before being subbed after suffering a clash of heads with Rubezic. | Getty Images
