CELTIC signed off for the Premiership's winter break with a 3-1 victory over St Johnstone in Perth.

Among the talking points from that game was the reinstatement of Vasilis Barkas to the starting line-up, the implementation of a back three and yet another injury to Kyogo Furuhashi.

Ange Postecoglou's Celts did, however, get the job done and go into the break six points adrift of Rangers at the top of the division.

What did the win over Saints tell us? Is the back three here to stay? Is the winter break coming at a better time for Celtic than it otherwise would have?

Sean Martin and Alison McConnell discuss.
