Moussa Dembele scored twice as holders Celtic eased to victory over closest challengers Aberdeen to move three points clear at the top of the table.
Aberdeen’s Graeme Shinnie had a couple of early shots on target, but thereafter it was all Celtic.
Kieran Tierney blasted in off the crossbar from a Dembele cross and then roles were reversed for the Frenchman to add the second.
Dembele headed the third after the break from close range.
Celtic’s sixth straight league victory over the Dons was indicative of their dominance in recent fixtures between the sides.
It not only ended the Dons’ unbeaten league run at 11 games but also stretched Celtic’s own sequence without defeat to 61 domestic games.
