Celtic have been held to a goalless draw by Dundee in Wednesday night's Scottish Premiership clash at Parkhead.
Despite boasting two thirds of possession and weighing in with 26 shots, seven of which were on target, the Hoops could not breach their opponents' rearguard.
The hosts ramped up the pressure from the off, but the best chance of the opening 20 minutes came from Dundee as Simon Murray forced the returning Craig Gordon into a fine save.
Celtic then began knocking on the door, with Elliott Parish blocking a deflected shot by James Forrest and Dedryck Boyata heading wide from a corner.
On the stroke of half time, a tackle by Boyata on Roarie Deacon sent the ball off the post, almost giving Dundee the lead with an own goal, though ex-Dees man Jack Hendry was then able to clear.
The second half saw the Bhoys step up their attacks as Odsonne Edouard and Hendry threatened, but the league leaders could still not find a breakthrough come the final whistle.
The result sees Brendan Rodgers's side move 10 points clear at the top of the table, with three more wins needed for them to retain the title.
Dundee, meanwhile, move five points clear of the relegation zone.
