Aberdeen failed to secure back to back wins at Parkhead for the first time since 2004 as they lost 1-0 to Celtic.
The Dons faced Celtic bidding to rack up another away win over the defending Premiership champions having triumphed 1-0 at Parkhead in the final game of last season.
The pressure was on Celtic boss Brendan Rodgers following the defending champions worst start to a league campaign in 20 years.
However the Hoops grabbed the three points courtesy of an improvised back-heeled goal from substitute Scott Sinclair in the second half.
Aberdeen made two changes to the side which edged past Hibs 6-5 on penalties in a draining League Cup quarter-final clash at Easter Road on Tuesday evening.
Striker Stevie May returned to the starting line up with Sam Cosgrove dropping to the bench.
Northern International winger Niall McGinn also returned ahead of loan Derby County left-back Max Lowe.
Celtic created the first opportunity in the second minute following a swift passing move that culminated in a Mikael Lustig cut back to James Forrest but the Scotland cap’ss curling 15 yard shot flashed wide.
The Dons threatened on the quarter hour mark when a corner kick swung in from the left was cleared as far as Gary Mackay-Steven at the edge of the box but the winger sliced his shot well wide.
It was a cautious start from both sides who were showing mutual respect.
Mackay-Steven was becoming increasingly influential on the left flank and burst down the wing in the 19th minute before crossing towards the far edge of the penalty area.
McGinn raced in to meet Mackay-Steven’s delivery but drilled a powerful 20 yard drive just wide.
Moments later McGinn crossed into the box and it just agonisingly alluded the unmarked James Wilson eight yards in front of goal.
Celtic were denied by the woodwork in the 25th minute when a curling effort from Odsonne Edouard from 25 yards beat diving keeper Joe Lewis only to crack off the far post.
Aberdeen came close with a superb attack when Mackay-Steven drove at goal and stepped past two challenges inside the penalty box to open up a shooting opportunity.
Keeper Craig Gordon somehow pushed it behind.
From the resultant corner Andy Considine, who netted in the 1-0 win in May, rose to power in a header that beat Gordon but Leigh Griffiths was on the line to kick clear.
In the 48th minute Dons keeper Lewis pushed a low drive from Callum McGregor wide for a corner.
On loan Manchester United striker James Wilson fired in a superb 25 yard curling effort from the right only to be denied by Gordon’s diving save in the 52nd minute.
Wilson was to come off on the hour mark to be replaced by Sam Cosgrove.
Celtic went ahead in the 63rd minute when a ball from James Forrest into the box took a deflection that sent it spinning up into the box.
Substitute Scott SINCLAIR used real improvisation and awareness to back-heel the ball into the net from six yards.
It came at a time when Celtic were becoming increasingly frustrated and Aberdeen influential.
In the 73rd minute Griffiths’ shot a free-kick wide of the defensive wall but keeper Lewis got down to block.
The Dons should have equalized in the 75th minute when Mackay-Steven whipped in an intelligent free-kick towards the onrushing Mikey Devlin but with the goal beckoning the defender volleyed it wide.
Deep into injury time Griffiths broke upfield and clearly pulled on the jersey of Devlin to gain an advantage. The referee waved play on and Griffiths raced upfield only to miss when chipping over the advancing Lewis.
