Celtic manager Brendan Rodgers challenged his side to put their foot down in the race for the title after they put six goals past Dundee to move 13 points clear at the top of the Scottish Premiership.
Arne Engels gave Celtic the lead from the penalty spot after Mohammed Sylla was penalised after a VAR check for a shirt pull on Auston Trusty.
Adam Idah put Brendan Rodgers' side in control at the interval with a powerful finish and they went through the gears in a dominant second-half display.
Daizen Maeda headed home a pinpoint Jota cross to make it three and just four minutes later, the Japanese forward found the net again with a delightful chip over Dundee goalkeeper Trevor Carson.
Maeda - playing down the right-hand side to accommodate new signing Jota on the other flank - was a constant threat with his pace in behind, and fully deserved his two goals.
Engels added his second and Celtic's fifth with a deflected strike from the edge of the box and substitute Nicolas Kuhn curled home a sixth to underline the champions' second-half dominance.
"It's been a really good season up to now," Rodgers said.
"You arrive to this point in a good place and then you've got to keep your foot to the floor. We have to stay concentrated, keep showing aggression on the pitch and keep our humility."
Kasper Schmeichel was never troubled in the Celtic goal as Dundee shipped six goals for the second game running following their heavy defeat by Hearts.
The Dens Park outfit stay 10th in the table, four points behind sixth-placed Motherwell and six in front of bottom side St Johnstone.
