A long-range strike from David Turnbull in the 15th minute proved the difference between the sides in a largely dull affair at Parkhead that lacked excitement.
The result saw Neil Lennon’s side close the gap on Rangers at the top of the table to 15 points with the two clubs now having played the same number of games (29).
Here's how the Celtic players rated:
9. Ryan Christie - 7
Struggled to make an impression in first half but came alive once moved into more central attacking role after break. Unlucky with lob that landed on roof of net. Photo: Craig Foy - SNS Group
10. Albian Ajeti - 5
Didn't see much of the ball and unable to stretch the Aberdeen defence in his 62 minutes on the park. Photo: Craig Williamson - SNS Group
11. Odsonne Edouard - 6
Lively figure in the first half but started to look jaded after the break. Never really looked like extending his scoring run to seven consecutive games. Photo: Craig Williamson - SNS Group
12. Tom Rogic - 5
On for Ajeti on the hour mark but never hit the heights of his recent performances. Photo: Ross MacDonald - SNS Group
