The Celtic Football Club are a Scottish football club based in the east end of Glasgow, which currently plays in the Scottish Premier League. Celtic are the champions of Scotland, having completed a hat-trick of titles on 22 May 2008, the final day of the 2007/08 season. Since the club's formation in 1888, Celtic have won the Scottish championship on 42 occasions and the Scottish Cup 34 times (a record), and won the European Cup in 1967. Celtic's home stadium is Celtic Park (commonly referred to as Parkhead after the area of Glasgow in which it is situated), the largest football stadium in Scotland, with a capacity of 60,832. Together with their Glasgow rivals, Rangers, they form the Old Firm, one of the most famous and fierce rivalries in sport. The club's traditional playing colours are green and white hooped shirts with white shorts and white socks.
In 1966/67 season, Celtic became the first British team to win the European Cup and are one of only two clubs ever to win the competition with a team composed entirely of players from the club's home country (along with Steaua Bucharest of Romania in 1986).[1][2]. All of the players, subsequently known as the Lisbon Lions, were born within a 30-mile radius of Celtic Park. Celtic won every competition that they entered that season: the Scottish League Championship, the Scottish Cup, the Scottish League Cup, the European Cup and the Glasgow Cup, to become the first, and so far only, team to win the Quadruple. Celtic also reached the 1970 European Cup Final, but were beaten by Feyenoord.
In 2003 Celtic reached the UEFA Cup final, where they lost 3–2 to FC Porto. Approximately 80,000 Celtic supporters travelled to Seville for this game, the largest foreign travelling support in history at the time. Celtic fans also received awards from UEFA and FIFA for their behaviour throughout the tournament.[3][4][5] Celtic have an estimated fan base of nine million, including one million in North America.
