Specialist Michael Stewart thinks Celtic will go from strength to strength in the wake of their 3-0 draw against Rangers.
And Neil McCann conceded the new Premiership bosses had implemented the perfect game plan to leave the champions dazed and confused.
Ange Postecoglou’s side edged their arch-rivals on a signature night at home as Reo Hatate netted a brace and Liel Abada netted again in the blockbuster opening 45 minutes.
Stewart believes there is no reason for Celtic to have doubts with the return of Kyogo and Tom Rogic.
And he has been warned by Rangers boss Gio van Bronckhorst that vast improvements must be sought if they are to regain control.
Speaking on Sportscene, he said: “This season is going very well for Celtic at the moment.
“I don’t think anyone would have imagined that they would be in this position, with the strength and depth that they have now in the team and the players to come back.
“When you think about the fact that Rogic, Jullien, Turnbull and Kyogo are not in this team, they look very strong.
“The momentum is definitely with them now. It’s a great prospect for Celtic.
“Because, Rangers, they have big questions they need to answer, it’s four games into the winter break and they’ve only won one.
“It’s a big, big ask for Rangers to come back now.”
McCann extolled Celtic’s virtues after the game and felt the Postecoglou side had a clear first 45 minutes against their biggest rivals.
And he believes it was only veteran keeper Allan McGregor to prevent Rangers from suffering further humiliation at the home of their biggest rivals.
He said: “For the first 45 minutes it’s as good as I’ve seen a team implement a game plan.
“On the other hand, it’s as poor as I’ve seen a team implement it against Celtic, in terms of the stature of Rangers going to Celtic Park.
“Ange Postecoglou must have a lot of credit here, he requires a lot of dynamism on this side.
“I think they gassed the game a bit but that’s completely understandable.
“It’s scary when he thinks Hatate isn’t fit enough, unbelievable.
“The way they move, they have a real way of playing, a style of football under Ange Postecoglou. It was so effective.
“Let’s be honest, if it wasn’t for Allan McGregor, the first half could have ended, 5. 6.”
