Celtic demolished Dundee 6-0 as the Scottish Premiership champions kept up the pressure on league leaders Aberdeen.

Ronny Deila's side were energetic in the opening stages, with top scorer Leigh Griffiths hitting the side netting from a free kick after Kris Commons was brought down just outside the area.

Dundee goalkeeper Scott Bain did well to keep out a Griffiths shot from six yards with 11 minutes gone, but the home side took the lead shortly after when Emilio Izaguirre pulled the ball back to Tom Rogic, who unleashed a pinpoint volley to put Celtic 1-0 up.

It was 2-0 just two minutes later, with Scotland international Griffiths controlling a Rogic cross and, after having his first attempt blocked, firing the ball into the back of Bain's net.

Rogic had two chances to grab his second of the game with just over 20 minutes gone, but watched as Bain was able to save both attempts.

Celtic keeper Craig Gordon was called into action after 42 minutes but was able to save a Gary Harkins free kick, with Kane Hemmings putting the rebound over.

James Forrest had an excellent run for Celtic as the half came to a close, but saw his shot crash off the Dundee bar to keep things at 2-0 at half time.

It took the home side 10 minutes of the second to pick up their third goal of the game as Izaguirre, after providing the assist for Rogic's opener, fired a right-footed shot into the back of the net.

The Honduran's hunger for goals continued as he found himself on the end of a Saidy Janko cross five minutes later for his second of the match, and Celtic's fourth.

Astonishingly, Izaguirre had the opportunity to secure a hat-trick in the 65th minute when Callum McGregor was brought down, but the defender fired his penalty over the bar.

Celtic went 5-0 up with a few minutes remaining when Scott Brown offered a precise finish from a Nadir Ciftci cut-back, and Ciftci himself then gave the Scottish champions their sixth of the afternoon one minute later with a shot through the legs of Bain.
