Official Puma Serbia soccer jerseys available with player kit printing. Serbia are official recognised by FIFA & UEFA as the official successor to both Yugoslavia and Serbia & Montenegro. In their previous incarnations they wore blue shirts with white shorts and white socks. However, after Montenegro declared independence in 2006 it was decided a new colour scheme was required to reflect the country's new identity. Red shirts with blue shorts and white socks were chosen to mirror the country's horizontal tricolour flag. Serbia feel they have a lot to prove after the achievements of their 1990's golden generation were held back by international sanctions on their government.
