The Norwegian coach believes that his side are favourites.
It is the Scottish Premiership leaders versus top dogs in the Scottish Championship as Deila's side look to secure the bragging rights at Hampden Park in what will be only the second Glasgow derby since Rangers dropped down several divisions in 2012.
The Bhoys won the last meeting - a 2-0 Scottish League Cup semi-final win 13 months ago - and the 40-year-old manager admits that his boys should certainly follow it up with another scalp on their fierce rivals.
Asked if Celtic would be favourites, the Norwegian said: “Yes, that’s fair. There’s nothing new there," Deila was quoted as saying by Herald Scotland.
“Of course I want to win the trophy and we now have two more games to hopefully lift it. We have to beat everybody to win the trophy and we are ready for that. Winning the trophy is the most important thing.”
The Hoops thrashed Greenock Morton 3-0 on Sunday to book their semi-final place, while Rangers swept aside Dundee with a 4-0 thumping to seal their passage into the last four.
Dundee United will face Hibernian or Inverness in the other semi after a 1-1 draw forced a replay. Both ties will take place on April 16 and 17.
Both sets of fans will be dreaming about this famous fixture on a far more regular basis in the future as Mark Warburton's Rangers sit 12 points clear in the Championship and, barring a monumental collapse, they should be back in the top flight come August.
