Celtic got the better of Rangers 2-0 at Hampden Park in Glasgow in the semi-finals of the Scottish League Cup last season.
First-half goals from Leigh Griffiths and Kris Commons proved to be enough for the Scottish Premiership side to win the tie.
It was the first Old Firm meeting since April 2012, and the atmosphere was electric. It was also Celtic manager Deila’s first taste of the Old Firm clash, and he was impressed.
“I spoke to Ronny after he beat Rangers at Hampden last year and he absolutely loved it,” former Celtic player Riseth told The Glasgow Evening Times.
“I had spoken to him before the game but after it he admitted that there was not anything that could have prepared him for it.
“I told him just to wait until he experiences a game against Rangers at Celtic Park – it is even better.”
Celtic and Rangers will face each other in the semi-finals of the Scottish Cup at Hampden Park next month.
It promises to be a fiercely competitive match, especially as Rangers are running away with the Scottish Championship title this season and could win it as early as next weekend.
The Gers have a very strong and talented squad, and Celtic could struggle against them.
