The Denmark legend, 39, will leave the Scottish champions when his contract expires at the end of next month. A serious shoulder injury has forced him to call time on his career.
In an interview with FourFourTwo, Schmeichel opened up on his European experiences with the club. He said: “It’s everything about the place, driving up to the stadium, this monumental stadium, you see the (Jock Stein) statue, you walk in, all the pictures, all the history of the club everywhere.
“You walk through the tunnel, there are all the plaques and all the names, and then being on the pitch and the noise. It’s deafening. It’s just the passion. All of it just grips you.
“In terms of actual intensity, I’d struggle to find anywhere louder.”
Schmeichel particularly enjoyed the Champions League nights at Celtic Park. He said: “One of my favourite things always was Champions League games, when the song (the CL anthem) starts, then this massive roar.
“I always used to love when we lined up to look at the opposition. See their faces. They’re like, ‘wow, this is incredible’.
“Any opposition player you may have known from the national team or somewhere else and you’re talking after the game, in the tunnel, in the changing room areas, they’re all like, ‘wow, this is immense’.”
