FIFA
In total, FIFA recognises 211 national associations and their associated men's national teams as well as 129 women's national teams; see the list of national football teams and their respective country codes. FIFA has more member states than the UN as FIFA recognises 23 non-sovereign entities as distinct nations, such as the four Home Nations within the United Kingdom and politically disputed territories such as Palestine.
FIFA eligibility rules
An emergency FIFA committee ruling judged that players must be able to demonstrate a "clear connection" to a country that they had not been born in but wished to represent. This ruling explicitly stated that, in such scenarios, the player must have at least one parent or grandparent who was born in that country, or the player must have been resident in that country for at least two years.
In November 2007, FIFA President Sepp Blatter told the BBC: "If we don't stop this farce, if we don't take care about the invaders from Brazil towards Europe, Asia and Africa then, in the 2014 or the 2018 World Cup, out of the 32 teams you will have 16 full of Brazilian players."
