The Polish Championship, officially known as the Ekstraklasa, is the top professional football league in Poland. It features 16 teams competing annually for the title, with matches typically held from August to May. The league operates on a system of promotion and relegation with the I Liga, the second tier of Polish football. Each season, teams earn points based on match results, with three points awarded for a win, one for a draw, and none for a loss. The team with the most points at the end of the season is crowned the champion, while the bottom teams face relegation to the I Liga.
