Celtic extended their lead at the top of the Scottish Premiership table after a 2-1 win over St. Johnstone at McDiarmid Park.
The Bhoys went three points clear of second placed Aberdeen in midweek thanks to a 3-0 win over Partick Thistle, and made the gap six points after beating St. Johnstone.
Just as they did against Partick, Celtic opened the scoring inside the opening minute, as striker Leigh Griffiths was played in on goal, and slotted the ball underneath the advancing Alan Mannus to give Celtic the lead.
Shortly after half time, Celtic made it two, with midfielder Stefan Johansen scoring a fine goal. The Norwegian took the ball down on his chest, flicked the ball away from an oncoming defender before volleying low into the net.
That looked to wrap things up for Celtic, but St. Johnstone came back, with Michael O'Halloran scoring for the Saints to bring them back into the game.
They put pressure on the Celtic goal in a valiant attempt to bag an equaliser, and whilst Craig Gordon made a fine stop to deny Dave Mackay late on, Celtic made to cling on for all three points.
That takes them six points clear at the top of the league, and Ronny Deila's men can now turn their attention to the big Europa League tie against Inter Milan on Thursday.
