They call themselves Celtic Football Club, but they are known everywhere as Celtic Glasgow. http://www.euro-goal.info/euro/europe/teams/celtic.htm http://www.soccerage.com/es/02/00471.html http://www.goal.com/es/Te/1467/index.shtml http://www.dfb.de/international/uefacup/archiv/2001/schemen/854.html http://sports.yahoo.com/m/world/news/uefacupres.html http://www.sport.fr/football/motscle/1361.shtm You could probably pull up at least as many links where they are called Glasgow Celtic and I have to say I was not aware that people even call it that at all because I had never heard that. Anyway...who cares .
Just to have the final word (since you provided lots of links) These all seem to be European web sites. I have never heard anyone in this country refer to them as anything other than Celtic, or Glasgow Celtic. Celtic MAD - the definitive Glasgow Celtic website. Independent news and stats from footymad.net I've only gone for one of the many links that Google showed up. It's probably a language thing. Everyone in this country calls Barcelona's stadium the Nou Camp, but in Barcelona, it's referred to as the Camp Nou.
