At least in my dialect/accent of English
Similar to this:
The french word for squirrel (écureuil) is equally hard for English speakers to pronounce as the English word is for French speakers
(I would also add that most English words with two R’s are hard for French speakers; mirror, error and the like)
The German word for squirrel (Eichhörnchen) is hard to pronounce for French and English speakers in different ways.
Though I have to admit squirrel/écureuil is the cooler pair because it seems to me they both derive from the same root but divererged in a way to make them difficult to pronounce for the other one.
