Celtic hero John Hartson has told The Scottish Sun that he thinks the Bhoys merely need to turn up to beat Rangers on Sunday afternoon.
Rangers' impressive 4-0 thrashing of Dundee last month sent them into the Scottish Cup semi-final, and when Celtic beat Morton 3-0 just a day later, the two Old Firm rivals were paired up together.
The two teams did meet at Hampden Park last season, with Celtic beating Rangers 2-0 in the Scottish League Cup semi-final - though Rangers have greatly improved since that day.
Manager Mark Warburton has revitalised the club, and has already clinched two trophies this season with the Scottish Championship title and the Petrofac Training Cup, setting his side up well to take on Celtic, despite the Bhoys being top of the Scottish Premiership.
Fans and some pundits may believe that Rangers have a chance of winning the game, former Celtic striker John Hartson has completely poured cold water on that suggestion.
Hartson, who scored on a regular basis against the Gers, has told The Scottish Sun that Celtic merely need to turn up at Hampden Park to coast past Rangers and into the Scottish Cup final.
The Welshman also claimed that Rangers will be lucky to lose 4-0 to Celtic, such is the divide between the two clubs, and really can't see any way that Warburton's men claim a win.
"Celtic virtually just need to turn up to win," said "All Ronny Deila has to do is make sure no one in his team poops their pants at Hampden tomorrow. If he can manage that then it’s a no-brainer. Mark Warburton’s Rangers will be lucky to get out of Hampden with a 4-0 defeat."
"But this is the Old Firm and the one thing everyone who has ever been to this game will tell you is true. Absolutely anything can happen. So maybe I’ll be proved wrong and it’ll be the blue half of the city celebrating at the final whistle. I just can’t see it," he added.
