text: I remember when Celtic Park was built, its changing rooms were not deemed to be good enough to class the stadium as 5 stars, however Celtic did take measures to fix this in 2003 and i believe it is of 5 star rating standards now, however i have not found evidence of it being on Uefa's 5 star listings yet, but this may change in the future - a club has to apply to host a european final before it can be added to the list.
