Charlie Nicholas believes it is Hearts who present more of a roadblock to Celtic in their chase for a Treble than Rangers.
That is the view of the former Parkhead icon who insists Robbie Neilson's men can put a sting in the tail when Ange Postecoglou and Co come to the capital in the Scottish Cup this weekend. Celtic have already secured the Viaplay Cup after beating Michael Beale's side in a tussle at Hampden last month and still retain a healthy nine-point advantage over their big rivals.
Postecoglou already has a trio of trophies in his locker and Nicholas insists he will be 'desperate' to join the list of former Parkhead managers who boast the accolade of securing a treble.

He said in his Scottish Daily Express column: "I think Hearts this weekend is the biggest threat to Celtic’s treble hopes.
"Ange Postecoglou’s side already have the League Cup in the cabinet and I believe the league is already done and dusted, I really do. I have thought that for a while now. Even if Celtic were to lose at home on Wednesday to Hearts I still can’t see Rangers catching them.
"The Scottish Cup tie with Hearts is the most intriguing of them all. If Celtic can get through then they will see the treble in their sights although I accept as long as Rangers remain in the competition then they will also fancy their chances of going all the way.
"Ange will be desperate to join the list of Celtic managers who have lifted a treble especially as he just missed out on it last season. You feel that Hearts are the type of team who on occasion can pull off a big result against Celtic or Hearts.
"The next two games are massive in the league and more so in the cup.
"I am not being disrespectful to Rangers here because the Old Firm games look after themselves but the fact they face Hearts in the cup makes it their biggest hurdle...to date."
