Celtic moved three points clear at the top of the Premiership with a 3-0 win over Partick Thistle at Firhill on Wednesday night.
Gary Mackay-Steven scored after just 38 seconds of his debut and fellow former Dundee United player Stuart Armstrong also marked his first appearance with a goal to give Ronny Deila's men a 2-0 interval lead in a fixture postponed from New Year's Day.
Stefan Johansen completed the scoring midway through the second half as Celtic made it seven wins out of seven without the loss of a goal in 2015.
