Brendan Rodgers knows no Scottish Premiership title is secured after the first game, but says Celtic managed a critical step after thrashing Kilmarnock on Sunday.
Reo Hatate, Liam Scales, Nicolas Kuhn and Anthony Ralston were all on target as the Scottish champions hammered their visitors 4-0 at Celtic Park.
Celtic have won their league opener in 16 of the last 17 seasons, losing the other 2-1 away to Hearts in 2021, though Rodgers acknowledged this is just the start for the Hoops.
I thought we were very connected, some of our passing and the speed of our game was very good, the Celtic manager told BBC Scotland.
Defensively we were very strong, the first goal came from that counter press. I have to be so pleased for the first game of the season.
