Sport plays an important role in the culture of Glasgow, the largest city in Scotland. Association football is particularly popular: Glasgow is known for the fierce Old Firm rivalry between Scotland's most successful clubs, Celtic and Rangers. The national stadium, Hampden Park, is located in the city and stages most home matches of the Scotland national team, as well as the finals of the Scottish Cup and Scottish League Cup. The Scottish Football Association (SFA) and Scottish Professional Football League (SPFL) are both also based at Hampden. The world's first official international match took place in Glasgow in 1872.
