Football is also popular in Armenia. The most successful team was the FC Ararat Yerevan team of the 1970s who won the Soviet Cup in 1973 and 1975 and the Soviet Top League in 1973. The latter achievement saw FC Ararat gain entry to the European Cup where – despite a home victory in the second leg – they lost on aggregate at the quarter final stage to eventual winner FC Bayern Munich. Armenia competed internationally as part of the USSR national football team until the Armenian national football team was formed in 1992 after the split of the Soviet Union. Armenia have never qualified for a major tournament although recent improvements saw the team to achieve 44th position in the FIFA World Rankings in September 2011. The national team is controlled by the Football Federation of Armenia. The Armenian Premier League is the highest level football competition in Armenia, and has been dominated by FC Pyunik in recent seasons. The league currently consists of eight teams and relegates to the Armenian First League.
