Celtic are set to face rivals Rangers in the cup semi final on Sunday.
The Scottish giants meet at Hampden Park on Sunday afternoon to contest the semi final of the Scottish Cup.
It is the second time the Hoops have faced the Gers this season, with Deila’s side triumphing 2-0 in the Scottish League Cup back in February.
With Rangers on a high after they confirmed their return to the top flight last week, and then won the Petrofac Training Cup, this game comes at an ideal time for them.
Warburton has tried to play down the significance of facing their fierce rivals though, labelling it as just another game for his side. Deila though, refutes that, saying it will be a special occasion for both teams.
"You can't say that. It is a game of football but this is special. It's a big game and something we really look forward to," he told Sky Sports.
"There's always pressure on these games. It is a semi-final, one game, and we have seen before that things can happen in these games.”
"We need to be very concentrated and we know we have a very good team when we are at our best so everything is in our hands."
There is no denying that the Old Firm derby is always a special occasion, despite what Warburton may have claimed.
This one will be particularly interesting though, with many keen to see if this game will be a gauge of how both teams will fare in the top flight next season.
In that regard, the game is arguably more important to Rangers than it is to Celtic, with them sure to be keen to discover how much ground must be made up after their long absence from the top flight.
