Former England keeper Peter Shilton suggested the 25-year old would have to leave Scotland in order to be a genuine international gloveman but Butcher does not agree.
"They would laugh and call it a Mickey Mouse league and all that rubbish," he told the Scotsman.
"Even Gazza said it was a pub league - but then when he came up here said it was the best league in the world! Peter Shilton has never played up here - although he's played badly for England up here of course!
"If he had then you would respect his opinion more, but I certainly dismiss that having played in both leagues.
"Fraser is an excellent goalkeeper and I played with Chris Woods who played for Rangers and England. It's not about the amount of saves you make, it's about your concentration levels, when you are called upon you have got to make those saves.
"When you play for England, with all due respect, you're generally not called upon to do much. But when you are you have to make the saves. So, in a way, Celtic and England are very similar. Joe Hart at Manchester City is the same."
