If Edinburgh pick up the victory underneath the Friday night lights, they will become the first Scottish side to win a European trophy.
Adding further intrigue to the match-up is the fact that Laidlaw spent eight years at Edinburgh prior to leaving for Kingsholm last summer.
And despite the fascinating master-versus-pupil dynamic at scrum-half, Hidalgo-Clyne is adamant the game is much bigger than just the No.9s.
"It's not about me playing Greig - it's about Edinburgh playing Gloucester," explained the 21-year-old.
"I play better when I focus on the team. Knowing each other does come into it but once you get into the game, you forget about it.
"Learning from Greig, especially for Scotland, has helped me greatly and I'm taking that into my game now. The knowledge of his game is huge.
"For example, he knows exactly when a winger is in and he can put it over the corner. His game management is brilliant.
"I want to adapt that into my game, with the speed of my game, learning how to control a game like he can.
"At the start of the season, I was a bit erratic - a lot of pace, but there was no control of the game.
"Now I want to bring in his side to it, where I can slow things down, control things, manage people and make my forwards feel relaxed around me."
