Poland has one of the most successful national football teams in Europe. The team has consistently been in the top 10 of FIFA rankings since the late 1980s, reaching a peak of 3rd in the world in June 1986. They have won the FIFA World Cup once, in 1974, and have finished third twice, in 1974 and 1982. Poland has also been a regular contender in the UEFA European Championship since their debut in 2008, having reached the quarter-finals in 2016.
The Polish national team can trace its origins back to the early 1920s, when the first official international match was played in 1921 against Czechoslovakia. The team has since become one of the most successful in Europe, and has had a number of prestigious players, such as Robert Lewandowski, Lukasz Piszczek, and Grzegorz Lato. The team has also had a number of successful coaches, including Jan Tomaszewski, Leo Beenhakker, and Adam Nawalka.
Polish football is well-supported in the country, with the top leagues having a large number of fans. The Ekstraklasa is the top tier of Polish football and is home to some of the most successful teams in the country. The two most successful teams in the league are Legia Warszawa and Lech Poznan, who have both won a number of league titles.
Poland also has a number of talented players playing abroad, such as Robert Lewandowski, who currently plays for Bayern Munich, and Arkadiusz Milik, who plays for Napoli. This shows the strength of the Polish national team and the talent that the country is producing.
