Leigh Griffiths is Celtic's super-sub as he snatches win over Ross County

Leigh Griffiths came off the bench to score a brilliant curling free-kick and earn Celtic a 1-0 Scottish Premiership win at Ross County.

Substitute Leigh Griffiths' sizzling second-half free-kick was enough to beat Ross County and extend Celtic's own British unbeaten domestic record to 64 games.

The Ladbrokes Premiership leaders had found the Staggies difficult to break down at the Global Energy stadium in Dingwall.
