After a tough 1-1 draw away to Astana during the week, Celtic continued their fine form with a 2-1 win away to Aberdeen.
The Hoops got off to a poor start however, as Dubliner Adam Rooney put Aberdeen in front after 25 minutes.
But Anthony Stokes then set up Stefan Johansen to make it 1-1 just before half time.
Both sides pushed for a winner, but when Celtic captain Scott Brown was sent off for a second bookable offence, it looked like it would be the home side who would nick a second goal.
But as the game entered the 90th minute, Virgil Van Dijk popped up at the back post to tap home and wrap up the three points for the visitors.
