Camilo Duran scored another stunner as Celtic continued their perfect start to the Scottish Premiership season with a 3-0 win over Aberdeen.
Benjamin Nygren and Hyun-jun Yang were also on target as Celtic killed the game off before the break.
Aberdeen hit the bar through Gavin Molloy just before Yang's strike but manager Stephen Robinson had seen enough and made four changes at the interval.
Duran has now scored six goals in five matches and Martin O'Neill might find it difficult to put him back on the wing when fellow centre-forward Kasper Hogh recovers from a thigh injury.
The Colombian opened the scoring out of the blue in the 14th minute with the latest in a series of spectacular strikes since joining from Qarabag in the summer.
There appeared to be little on when Duran collected Nygren's pass but he thumped a 20-yard strike in off the bar with limited backlift.
Duran also forced four first-half saves from Marius Muller and fired over from a bouncing ball after Yang's cross had caused chaos in the Dons defence.
14: GOAL! Duran fires the hosts ahead with a stunning long-range strike.
19: CHANCE! The Colombian should have doubled the hosts' lead, only to fire over from close range.
24: CHANCE! Faced with just Muller to beat, Duran's low shot is saved by the Dons No 1.
34: GOAL! Nygren's mishit shot somehow bobbles past Muller.
45+1: BAR! Molloy heads against the bar from three yards out with the goal empty.
45+1: GOAL! Duran feeds in Yang, who makes no mistake.
77: CHANCE! Mheuka very nearly scored with his first touch, only to be denied by Muller.
Celtic boss Martin O'Neill:
"We played very well with some really good goals. Camilo's a star player.
"Camilo set the tone for us, I think perhaps maybe all season he's done that. He's a really class player.
"He scored a great goal and obviously until you get that goal you just have to be on your guard as much as anything else.
"I thought probably the big moment of the game was them hitting the bar with the header from the corner kick.
"It seemed pretty comfortable at the end and we played some really good stuff as well too, so I'm delighted with that."
Aberdeen boss Stephen Robinson:
"We got beat by a ruthless side. We made mistakes and got punished for them.
"We didn't have the belief that we've shown in training, in the second half. We didn't have that belief in the first half to play. If you don't get ownership of the game, it's difficult to get out.
"So, at 2-0, we hit the crossbar, and the fine lines in football, they go up the other end, we make a mistake, effectively the game's over.
"To an extent, I get a response and they show that they can pass the ball under pressure and they can play, and they are good players. And that's a positive I have to take from it.
"Our season won't be defined by getting beat by Celtic. Am I disappointed? Of course I am. I know the team are better than what they've showed.
"But it's up to me, it's my fault that they haven't got the belief to do what they did in the second half and be brave. It's too late at 3-0 down, and I take full responsibility."
