New gaffer Pedro Caixinha, Murty will take over tomorrow and Murty will resume his old job as the Under-20s coach.
Murty said: “It’s fairly well known that my dad and all his family are from Glasgow.
“So, I was brought up understanding the history of this derby game, knowing what it’s all about and what the occasion means.
“He’s still a Celtic fan now. All of the family are Celtic supporters and they reiterated that to me earlier this year.
“I met up with them and I got four hours of absolute dog’s abuse.
“They said: ‘What are you doing?’ And I said: ‘This is what I’m doing.’ Then I sat back and accepted their backlash.
“The thing is, my old man is a great believer in self-determination. He better want me to beat Celtic!
Murty looked ahead to this afternoon’s confrontation and said: “This game will be very new to me. There’s no doubt this will be like nothing I’ve ever seen before.
