Dunfermline Athletic 0-3 Celtic
Celtic swept aside Dunfermline to retain their two-point lead at the top of the Scottish Premier League table.

Five minutes before the interval, Victor Wanyama volleyed in a Charlie Mulgrew free-kick at the back post.
Mulgrew turned scorer in the 69th minute with a curling free-kick that evaded Pars keeper Chris Smith to seal the win.

Stokes came in for the injured Beram Kayal for the 100th meeting between the sides, with Emilio Izaguirre on the bench as he looked to make his comeback from a broken ankle.

Celtic gave the hosts a scare after six minutes with a Mulgrew corner that battered its way around the Dunfermline penalty area before being swept clear.
Moments later, Georgios Samaras delivered a cool ball across the face of goal, but none of his team-mates was on hand to profit.

Wanyama almost made it two on the half-volley from 25 yards out with a blistering strike that Chris Smith tipped on to the bar and out for a corner.
Stokes and Samaras worked the ball into the Dunfermline penalty area but failed to make it count before Martin Hardie mistimed a shot that drifted wide of goalkeeper Fraser Forster's left-hand post.

Gary Hooper dinked a header towards the Dunfermline goal from a Joe Ledley cross, but the ball drifted wide of Smith's left-hand post.
James Forrest blitzed his way past the Pars' defence and slipped the ball across the six-yard line, but no-one was there to knock the ball in at the back post.
An intense spell from Dunfermline saw Hardie fire in a shot from 18 yards out that inched past Forster's right-hand post.
The match was over as a contest when Mulgrew flighted in a curling free-kick from wide on the right that left Smith flapping at air in the Dunfermline goal.
