The Old Firm rivals meet at Hampden Park next month.
Celtic hero Frank McAvennie believes that Scott Brown, Kris Commons and Leigh Griffiths will all be crucial to the Hoops' chances of beating Rangers in the Scottish Cup semi-final, the Evening Times reports.
The Old Firm pair have been drawn together in the last four of the competition and will meet next month at Hampden Park to decide who will face either Hibernian or Dundee United in the final.
And with the game being like no other in Scottish football, McAvennie claimed that Brown's leadership will be a key asset for Ronny Deila's men.
"They need to go into it believing that they are the best team on the park," he told the Evening Times.
"That is when you need the likes of Scott Brown to get them all going. He is a great character, a great leader but he hasn't quite been himself since he came back from injury. He has a few weeks now to get up to speed and these are the guys that if they are on their game, I think will be too much for Rangers."
As well as Brown marshalling the side, the 56-year-old also discussed how important both Commons and Griffiths will be if they hope to beat their bitter rivals, with the former being especially vital to the team's cause.
"He is the best player at the club, simple as that," he added.
"Commons and Leigh Griffiths are the guys in there who can get you something from nothing.
"He is also a big-occasion player. Commons has shown time and time again that he steps up to the plate when it comes to the games where it matters."
While Griffiths' form this season suggests that he will have no problem giving Mark Warburton's side problems when they meet in mid-April, the other two players that McAvennie believes Celtic should be counting on have not been quite as reliable this term.
As the former West Ham forward alluded to, Brown has struggled to stamp his authority on games since his return from injury, while Commons has arguably been a victim of Deila's desire to just play one up front as he has only returned four goals in the Scottish Premiership this term.
Nevertheless, McAvennie is convinced that the trio have the quality to ensure that it is Celtic that secure bragging rights once again.
