Ange Postecoglou branded Celtic's nine-point lead over Rangers as "irrelevant" as he strives for the perfect Parkhead performance.
The Celtic boss was left a little disappointed with aspects of the display in the 2-1 win over Livingston despite earning a tenth consecutive triumph.
An own goal from Ayo Obileye and a smart Kyogo Furuhashi finish was enough for the win even if Nicky Devlin pulled one back before the break.
But Postecoglou was not thrilled with the performance even if he was delighted to add to a winning streak in the league.
Detailing his "principles of play", the Australian boss bemoaned the lack of bodies in the box for crosses in the win at Celtic Park.
"The result is positive but I thought the performance wasn't one of our best," Postecoglou told BBC Sportsound.
"First half was okay, we controlled the game the way we wanted to, but I was just really disappointed that we got into some great areas, some great balls across the box but we didn't have bodies in there.
"Part of our principles of play is to make sure people hit certain areas when the ball is in wide areas and they weren't doing it today. It's disappointing because that is the discipline we need.
"Second half it was okay but we never quite got to grips with totally dominating the game we wanted to."
Postecoglou was then quizzed on his desire to increase the performance level even if his side boasts a comfortable lead in the title race over their Glasgow rivals Rangers.
"It doesn't matter, nine points clear," he continued. "That's irrelevant to what we want to be and the way we want to play. We want to play our football a certain way and we can't go away from that.
"Ultimately we have won another game of football and we need to make sure we keep doing that on the back of strong performances."
