How big is Glasgow Celtic's fan base?

Answer 1

A recent poll by UEfa showd that Celtic were one of Europes best supported teams outside of their own country. UEFA showed that Celtic can claim a fan base of around 200,000 in mainland Europe alone. This does not count the rest of the world of course so it can be anybodys guess. It was reported 3 years ago that in New York alone more than 7000 Celtic fans watched every Celtic game live on TV in bars and supporters clubs.

In 1967, Celtic became the first British team, and only Scottish team, to win the European Cup:[1][2] the players, subsequently known as the Lisbon Lions, were all born within a 30-mile radius of Parkhead. Celtic won every competition they entered that season: the Scottish League Championship, the Scottish Cup, the Scottish League Cup, the European Cup and the Glasgow Cup. Celtic also reached the1970 European Cup Final, but were beaten by Feyenoord.

In 2003, Celtic reached the UEFA Cup Final, where they lost 3-2 to FC Porto. An estimated 80,000 Celtic supporters travelled to Seville for the occasion.[3][4][5] Celtic fans received awards from UEFA and FIFA for their behaviour at the match.[3][6][7][8] In April 2003 the club was estimated to have a fan base of nine million people, including one million in North America.[9
