Celtic put their mauling in Madrid behind them with a symmetrical 6-0 win over abject Aberdeen in their cinch Premiership battle at Parkhead.
The Hoops had been crushed 6-0 by Atletico Madrid in their Champions League group stage game in Spain on Tuesday night after going down to 10 men, while the Dons exited the Europa Conference League on Thursday despite an impressive 2-2 draw with PAOK in Greece.
Back in the safer environs of the cinch Premiership, South Korean 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 their eight-point lead over their Old Firm rivals going into the international break, albeit the Light Blues have a game in hand.
Unsurprisingly, both sides made changes following their European exploits.
Norwegian midfielder Odin Thiago Holm came in for Paulo Bernardo to make his first league start while 21-year-old Yang replaced Daizen Maeda, injured in the challenge that led to his red card against Atletico Madrid.
Bojan Miovski, Jonny Hayes, Leighton Clarkson and Dante Polvara returned for the visitors.
The minute’s silence to mark Armistice Day was disrupted by some inside the stadium, which was missing several hundred registered Green Brigade members who remain suspended from Celtic Park for “unacceptable behaviours”.
The Granite City men were immediately under the cosh and in the fourth minute keeper Kelle Roos made a fantastic save from Furuhashi’s powerful drive and midfielder Matt O’Riley somehow bounced the rebound over the bar from five yards.
Roos was soon beaten, however, when he missed a Palma cross from the left and Yang, who signed from Gangwon FC in the summer, gleefully headed in from close range.
Aberdeen slumped further behind when Yang’s clever reverse pass found O’Riley and his cut-back was slid in at the near post by Furuhashi for his ninth goal of the campaign.
The visitors were struggling to cope but they had a great chance in the 22nd minute when Polvara sent Hayes racing clear but the former Celtic player slashed his shot wide of the target.
Furuhashi sclaffed another chance at the other end and Roos tipped terrific efforts from Holm and then Palma over the bar, as Celtic continued to boss possession.
A robust challenge by Dons defender Slobodan Rubezic on Furuhashi early in the second half saw both players require treatment for head knocks, the former picking up a yellow card from referee Willie Collum.
Furuhashi, however, had to be replaced by Oh, while Holm made way for Turnbull, before a Miovski flick from a Nicky Devlin cross had Celtic keeper Joe Hart making his first save.
Yang took a cut on the face in a challenge by Jack MacKenzie which would soon see him replaced by James Forrest before Celtic were awarded a penalty.
Referee Willie Collum was asked by the VAR to have a look at his pitchside monitor after MacKenzie had wiped out Oh inside the box.
When Collum pointed to the spot, Palma took a slow approach before hammering his spot-kick past Roos.
Turnbull drove in off the post in the second minute of added time and Oh added a fifth with a header from a Palma cross, before running through to drive in a sixth from an O’Riley pass.
