'The goal was perfect' - Griffiths on target in 100th appearance as Celtic ease to Old Firm win
Celtic underlined the huge gulf in class between the Old Firm rivals as they claimed a 2-0 victory over Rangers at Ibrox.
The Light Blues, without a league win against their bitter rivals since 2012, made the opening derby clash of the season a compelling watch for 45 minutes.
But goals from Tom Rogic and Leigh Griffiths after half-time swung the game decisively in Celtic's favour as they opened up an eight-point lead over Pedro Caixinha's side.
Griffiths has scored 67 goals in his 100 Scottish Premiership appearances for the Hoops, and speaking about his record, Griffiths told Sky Sports: "It's not too bad.
"I could have had a few more with the chances I've missed, but scoring on my 100th league appearance for Celtic is nice.
"I'm happy with a goal, three points, clean sheet. We'll head back down the road and get ready for Wednesday (against Anderlecht in the Champions League)."
Celtic boss Brendan Rodgers was full of praise for Griffiths, saying of his achievement: "It's exceptional.
"To come into a club like this and to score that number of goals in 100 games it's absolutely brilliant. But it's what he is, he's done it all his life.
"I was talking to him in midweek about when he was at Dundee and he played 60-odd games there and got 30-odd goals so it's what he is.
"He goes into every single game he plays believing he can score and the goal was perfect, the second one, in terms of our build-up play.
"It was a wonderful pass from young Pat (Roberts) to free Griff up to score. So it's an exceptional achievement."
