Watch highlights of Celtic's 3-1 win over St Johnstone in the Scottish Premiership.

Gary Mackay-Steven scored his first two goals of the season as Celtic restored their six-point lead in the Premiership with a victory over St Johnstone at Parkhead.

Stuart Armstrong was also on target, regaining the lead for Celtic after Steven MacLean had fired an immediate response to the ninth-minute opener.

Leigh Griffiths was strangely wasteful with his shooting after hitting seven goals in three games but he played a key part as Celtic scored with their first decent attack.
