Stuart Armstrong has put Rangers to the sword in a Scottish Cup semi-final before, but knows that an Old Firm derby produces the kind of pressure that no other game can muster.
The midfielder was in the Dundee United side that claimed a 3-1 victory over Rangers at Ibrox two years ago.
However, the former Scotland U21 captain holds no illusions over the enormity of an Old Firm derby.
"I don't think you can treat it like any other game because it's not," he said.
"It's a big tie, a chance to get to the final. It's Celtic against Rangers.
"I think it will be a good experience. It's something I've never seen live, something I've never experienced before. It's exciting."
The 24-year-old struck the opening goal to send the Tangerines on their way to a Scottish Cup final victory over St Johnstone in 2014 and hopes to come away with the same result on Sunday.
"That was a great game. I scored and it was an all round great day.
"If we could experience those sort of emotions again, this weekend it would be great.
"It's useful that you have experienced these kind of big games before, those pressurised games. This one will be slightly different but again the stadium will be full.
"I'm sure there will be a bit of chat about that this week leading up to the game. I think it will be a good game with lots of chances. They like to score goals and so do we, so I'm sure it will be a good one to watch.
"I would say there is pressure on both sides. It's a pressurised game, it's a semi-final. It's a chance to get into the final of the Scottish Cup, the biggest cup competition in the country."
