He knows, however, that Old Big 'Ead himself wouldn't expect Marlon and his colleagues do anything other than try and get three points from Forest on the occasion of their first home league game since he passed away.
That pragmatism is echoed by Marlon, who says:
"I can't wait to go there, get three points, and see the boys but I have is a job to do and I have to get on with it."
However, on a day which will see the trophies Cloughie won with Forest on display at the game, Marlon knows only too well that there will be an understandably heightened atmosphere.
"After what has happened this week it will be an emotional day," says Marlon.
And he should know as well as anyone, for he reveals:
"Cloughie brought me to the club; I knew him when I came for trials and he signed me.
"He was a fantastic manager; when I went up there I saw how the lads acted under him and how they played - the club was fantastic then.
"His qualities? Everything. Man management, knowing the players, knowing what to do...he had his own way and he was strict.
"If he says something it goes - full stop. He was quality. He never had to rollock me because I always did what he said - definitely!"
As to how he heard the news of Clough passing away, he says:
"My scout phoned me up and told me; I felt sad because I know his son as well from when he came to Forest - he was a good friend of mine.
"I am waiting to find out when the funeral is because I want to go to that - Forest was a family affair and Cloughie will never be replaced."
