Some articles say that naturalized players also include those who are born aboard but are eligible to play because their parents are citizens of the country.
That is an issue of whether the country (of their parents) automatically grants citizenship to the child born abroad. Nothing to do with football!Some articles say that naturalized players also include those who are born aboard (abroad) but are eligible to play because their parents are citizens of the country.
It also goes the other way round, a player may loose the right to play for his native team if he gets a new citizenship. Before Swedes were allowed dual citizenships, one well-known Swedish ice-hockey player was kicked out of the Swedish national team, where he had played for several years, when it was discovered that he had applied for U.S. citizenship (he had played professional ice-hockey in the U.S. for many years), and was no longer considered to be a Swedish citizen, although a native Swede by birth.Some countries don't allow multiple citizenships, so if they want to play for the national team, they are required to do naturalization and abandon their original citizenship once their application is granted.
