Having watched Old Firm rival Rangers play out a second successive 1-1 draw, Brendan Rodgers' men eased four points clear a day later, also earning a measure of revenge for May's penalty shoot-out defeat to Aberdeen in the Scottish Cup final. 

Aberdeen's Adil Aouchiche worked Kasper Schmeichel from range early on, but after settling into the contest, Celtic took a 27th-minute lead via new signing Nygren.

Kieran Tierney beat Nicolas Milanovic to reach the left-hand byline before sending in a low cross, which Nygren directed past Dimitar Mitov while falling backwards.

Nygren then fired over the crossbar on the rebound after Mitov denied Hatate, with the Dons goalkeeper also keeping out Daizen Maeda early in the second half.

However, he was powerless to prevent Hatate from doubling the champions' lead with a blockbuster effort from the edge of the penalty area, which clattered the underside of the crossbar on its way in after the midfielder was teed up by Nygren in the 66th minute.

Celtic were comfortable from there against an Aberdeen team that prop up the early-season table with two defeats and no goals scored.
