wiki :naturalization is the acquisition of citizenship and nationality by somebody who was not a citizen or national of that country when he or she was born.
In general, basic requirements for naturalization are that the applicant hold a legal status as a full-time resident for a minimum period of time and that the applicant promise to obey and uphold that country's laws, to which an oath or pledge of allegiance is sometimes added. Some countries also require that a naturalized national must renounce any other citizenship that they currently hold, forbidding dual citizenship, but whether this renunciation actually causes loss of the person's original citizenship will again depend on the laws of the countries involved.
yes. christian gonzales is a naturalization player. no doubt about it. he born in uruguay and married with Indonesian girl then live for 7 year in indonesia. why he just do naturalization now? because he must live more than 5 year according to indonesian law. one of another requirement to be indonesian is that the person must have a family member or blood line. just like irvan. and also gonzales.
its not true that indonesia pushing team skill by just adding new naturalization player suddenly for aff. gonzales have been apply for this membership since 10 years a go and he following all the requirement.
indonesian team has been runner up since 1999, and in 10 year never have any naturalization player. so its kinda new and attract people attention.
IMHO you must see that after loosing 1-7 to uruguay all indonesian half-blood player in seri a italia dutch liga australia liga etc rushing back to indonesia. so its a advantage and i hope we be mature to see it. i mean we respect malaysian team dont want to use naturalization but i hope the same respect come from them to our choice using naturalization.
i mean its like a eating burger. some people like to use chili some like to use tomato ketchup. some just like to eat it without any.
of course the people eat that burger have their own reason why use or why not right? instead blaming, cursing, that other burger taste great, why not enjoying your own choice and

indonesia 4 times went to final. they always using their nation player..
only this time they include 2 import players.
even without gonzales/irfan they're still have good team..
like boaz and yongky
boaz not played this time because of his undiciplined manner with riedl. if not, perhaps he will play as right winger or striker
