I'd like some information about Serbia Sports. 
 No problem! Football is the most popular sport in Serbia and it is the largest sporting association in the country as well. The Football Association of Serbia even has an impressive amount of 146,845 registered players. 
 Interesting, Do they play the world cup? because I've never hear about its team. 
 Actually, the Serbia national youth football teams have competed in and won both the 2013 U-19 European Championship and the 2015 U-20 (under 20 years old) World Cup! 
 That's cool, I'd like to learn about its Etymology, do you have any interesting information? 
 I do not have that information at this current time. Would you like to know more about the Economy? 
 Sure, I don't mind, but really want to learn about Etymology. 
 I apologize sincerely for not having more information regarding Etymology at this time. However, Serbia's industry was the economy sector which was hit the hardest and took the most damage by the UN sanctions and trade embargo and NATO bombings during the 1990's, and surprisingly transition to market economy during the 2000's. 
 This also is a piece of good information, is there any more information that I can find useful? 
 Actually, yes there is! The Serbia national football team allegedly lacks relative success even though they qualified for 3 out of the past 4 FIFA World Cups. 
 I guess that's why I haven't heard about its team. thank you for all the informations. 
 It was my pleasure.
