Celtic are not playing with the same tempo now but they are still the dominant side as a shot from Tom Rogic is deflected wide.

Another free kick on the edge of the box and another effort from Odsonne Edouard. This one is curling inside the post and it needs a fantastic, full-stretch save from Joe Lewis to keep it out.
Aberdeen 0-4 Celtic
Dons gaffer Derek McInnes wasn't hanging about when the half-time whistle sounded.
The air was thick with hostility and frustration, with nothing much to lift the mood of the home fans since the interval.

Quote MessageI know Sir Alex Ferguson has the freedom of Aberdeen but it looks like Kristoffer Ajer has been given that honour too
Aberdeen 0-4 Celtic
Once again, Kristoffer Ajer races from deep in his own half to the edge of the Dons penalty area. There's just no stopping the big Norway defender once he gets motoring.

Quote MessageIt's a foul, but at least Aberdeen are putting a foot in. They were not doing that in the first half.
Aberdeen 0-4 Celtic
Scott McKenna thunders into Odsonne Edouard and then does the same to Boli Bolingoli, leaving both men in a heap. The Aberdeen defender is at least showing some fight but he needs to keep a lid on it.
Edouard picks himself up and curls the free kick over the top.

Jeremie Frimpong is still full of beans as he has a run at the Aberdeen defence and clips a delicate ball in the direction of Mohamed Elyounoussi but Shay Logan is able to make a stretching interception.
Aberdeen 0-4 Celtic
It's very quiet inside Pittodrie now, with a good few fans already on the way home.
Aberdeen don't seem to have learned their lesson as Kristoffer Ajer breaks forward from central defence, deep into enemy territory, for the umpteenth time.
Aberdeen 0-4 Celtic
James Wilson and Craig Bryson are on for the home side. Niall McGinn and Connor McLennan are the men to make way.
Nir Bitton takes over from Celtic defender Christopher Jullien, who gets a rest after his goal-scoring heroics against Lazio on Thursday.
HT: Aberdeen 0-4 Celtic
How does Derek McInnes approach his half-time talk? It's damage limitation time for Aberdeen, who have been simply woeful.
Home fans will be getting worried about a repeat of the 9-0 defeat dished out in Glasgow in November 2010.

Quote MessageI don't think Celtic would have expected Aberdeen to be so passive. To be able to come up here and control the game so easily.
One way traffic at Pittodrie, with the champions running riot.
Who saw 4-0 at half time?
Odsonne Edouard and Jeremie Frimpong with early goals, while James Forrest and Mohamed Elyounoussi are also on the scoresheet.

Quote MessageMy word, it's incredible. One of Aberdeen's centre backs getting muscled out by Mohamed Elyounoussi. It's so, so simple.
Mohamed Elyounoussi
Dons fans streaming towards the exits now...
Tom Rogic has all the time in the world to curl a cross in from the right and Mohamed Elyounoussi has no trouble holding off Mikey Devlin to take it down on his chest and thump home.
Aberdeen 0-3 Celtic
Niall McGinn whips a free kick into the Celtic penalty box, Mikey Devlin gets his head to it but the ball just runs harmlessly out of play. Fraser Forster gets a rare touch as he sets up his goal-kick.

Quote MessageIt has so far been as bad a performance from Aberdeen as you can imagine.

Quote MessageThat was a goal and a half. All about one-touch passing. Almost every single player in the final third is involved in that passage of play. And then James Forrest is allowed to walk it into the net.
