Leigh Griffiths believes that Celtic should have killed the game off against Inverness on Sunday.

The reigning Scottish champions dropped their first points of the season in an entertaining 2-2 draw as Alex Fisher scored a late equaliser for Inverness.

Celtic were keen to maintain their 100 per cent start to the new season and looked to be heading that way after Scott Sinclair gave them a 2-1 lead in the first-half.

The attacker has now scored in each of his five league appearances this season and has made the perfect adjustment since his move from Aston Villa in the summer.

Tom Rogic had opened the scoring for the visitors and Billy Kee had levelled the match for Inverness in a busy first period.

Griffiths, who missed the match with a calf injury, revealed his disappointment at the result on his official Twitter account.

“Disappointing result. Always a difficult place to go,” he said. “Game should’ve been out of sight though before the equaliser.”

Griffiths, 26, led the line with huge success last season, bagging 40 goals and providing eight assists in 51 games in all competitions.

He has now missed the games against Rangers, Barcelona and Inverness since he was forced to pull out of Scotland’s squad for their World Cup qualifier during the international break.

Brendan Rodgers’ side remain unbeaten in the league and have a three point cushion over Hearts at the top of the league, having also played a game fewer.
