Celtic manager Brendan Rodgers said the Scottish Premiership title is "nowhere near done" after Reo Hatate's late goal downed closest rivals Aberdeen at a wet and windy Pittodrie and took the champions seven points clear at the top.
In a tight first half, chances were few and far between as tackles flew in and the conditions hampered both sides in the final third.
Luis 'Duk' Lopes had a low shot saved by Celtic goalkeeper Kasper Schmeichel, while Alistair Johnston's header was turned round the post at the other end by the midriff of Jamie McGrath.
Paulo Bernardo sent a wind-assisted corner sailing directly into the far corner of the net, but it was disallowed for a foul on Aberdeen goalkeeper Ross Doohan.
Celtic dominated possession after the break, but were repelled time and again by heroic Aberdeen defending, led by Slobodan Rubezic.
However, with time running out, a delightful pass over the top from Greg Taylor found Hatate, and the Japan midfielder rifled a shot into the bottom corner in what could already be a telling blow in the race for the title.
Ester Sokler had a big chance for the hosts to equalise soon after, but his shot was brilliantly blocked over the bar by Cameron Carter-Vickers after Auston Trusty scuffed his clearance.
"There are 38 games so it's nowhere near done," Rodgers said. "I understand people will look at it that way but for us there's such a long way to go.
"We're trying to get through the games, play well, but there's no thought of [the title] in the players' minds."
