Celtic stay unbeaten in the Scottish Premiership.
A brilliant individual goal started from within his own half and slotted home by the Dutch centre half Virgil van Dijk in the fifth minute won it for the Bhoys at St Johnstone.
Elsewhere Motherwell won by a single goal at Aberdeen - Kilmarnock won 4-0 at Hearts - St Mirren thumped Dundee Utd 4-1 - Hibs won 2-0 at Ross County and it finished nil all in the battle of the Thistles between Partick and Inverness Calodonian.
