Jamie McCart is not expecting an easier time of it when St Johnstone make the trip to Glasgow’s East End on Sunday.
Instead, the no-nonsense defender stressed that every member of the Perth squad must hit optimum level to be in with a chance.
It is no secret that Celtic are a side who have been struggling for form and their manager Neil Lennon is under scrutiny.
Saints, on the other hand, are performing with real confidence after piecing together an unbeaten run which sits at 10 games.
But McCart said: “It’s always the toughest game of the year going to the champions.
“Regardless of form, we’ll need to be at top level to come away with anything. We know how dangerous and good they are.
“It’s just a case of preparing right and trying to do the best we can.
“They are nine-in-a-row champions and have been excellent for years. It's maybe just a wee dip in form.
“But we know they’ll be looking to bounce back. We want to try and stop that.
“You always need to look at Celtic as the same because of the real quality of players.
“It’s up to us to be on top form and playing well if we’re wanting anything from the game.
“You really need everyone in the team to be at it. You need
discipline and hard work when you go to Celtic Park.
“A wee bit of luck always helps. If we’re organised and structured, it will go a long way.”
Saints’ impressive run without defeat has earned manager Callum Davidson plaudits from around Scottish football.
The Perth men haven’t actually lost a game since a harsh 2-0 league defeat against Sunday’s opponents way back on October 4.
A solid Betfred Cup group campaign has certainly helped the cause and McCart reckons the competition provided the perfect platform.
He said: “Sometimes people look upon the cups as something to get out of the way. But the group stage of the Betfred Cup was really
positive for us. I know we played lower league opposition in Brechin but scoring seven goals was great and we’ve built on it.
“The gaffer made a really good point in the earlier stages of the competition.
“You need to look at the bigger picture and qualifying from the group leaves you a couple of games away from Hampden.”
Saints skipper Jason Kerr has been recovering from a back problem and is set to make his comeback this weekend. In his absence last Saturday, Shaun Rooney was a star performer.
For McCart, it shows the strength in depth.
He added: “Everyone has shown that, even in the case of injuries, they can step in straight away and we’ll still have quality through the squad.
“Shaun did really well at Motherwell and has proved he is more than capable in a position that isn’t natural to him.
“It’s a testament to him that he has come in and performed.
“He certainly has speed and when he gets going he is hard to stop.
“But I don’t think anybody is getting near Mikey O’Halloran’s pace anytime soon.”
Craig Conway remains out for Saints but Danny McNamara is expected to return after missing Motherwell with a tight hamstring. Murray Davidson is "touch and go" ahead of Sunday.
