When modern soccer was started to be played in Turkey at the beginning of the 19th century, it was a game more for like non-Muslims. Of course, soccer-lovers of our days have no idea about that.
In the year 2000, Galatasaray defeated Arsenal in the final and took UEFA cup to its museum and this became an important point of Turkish Soccer history. That year all streets were painted yellow-red as it is the team color. Also Turkish National Soccer Team got their greatest success by coming third in the 2002 FIFA World Cup.
All around the county was nicely decorated with huge Turkish flags.
