"Polish national football team" can be translated into Polish as "Reprezentacja Polski w piłce nożnej". The team's most common nicknames include "Biało-czerwoni", which means "The white-reds", and "Orły", which translates into "The Eagles". In English, the team is also widely known as "The White Eagles", based on Poland's national coat of arms. Supporters The Polish team enjoys widespread support in Poland and among Polish diaspora worldwide. Some fans of the team are reportedly fanatic and often violent, with connections to Polish organized crime syndicates. Supporters of the team have been involved in a number of incidents, such as during UEFA Euro 2012, held in Poland, when Polish and Russian supporters clashed prior to the encounter between the two countries' teams. A notable chant among Polish fans is "Polska, biało-czerwoni" ("Poland, the White-Reds"). National kits The national kits of Poland reflect the colours of the national flag, which are white and red. Apart from minor details (in the 1920s the socks in the home kit were striped), the design remains unchanged since 1921. The home kit consists of a white shirt, red shorts, and white socks; the away kit is all red (though sometimes worn with white shorts). On the rare occasions when both home and away kits clash with the opponent's, a colours third kit is available, usually in either black or blue (currently navy blue with white-red sleeves). The kit has traditionally been adorned with the coat of arms of Poland, i.e. the crowned white eagle. Until 2006, the coat of arms featured only the inscription "POLSKA" in capital letters above the eagle, and not, as with many other national teams, the national football federation logo. The Euro 2012 kits were the first to feature the logo of the PZPN. When the kit was first launched it did not include the coat of arms, but it was restored shortly thereafter. Since 2009, the kits have been provided by Nike. Stadiums Main stadiums Stadion Śląski in Chorzów was built in 1956 and seats 47,246.
