Nemzeti Bajnokság I  The Nemzeti Bajnokság (, "National Championship") is the Hungarian professional league for association football clubs. The league is currently known as the OTP Bank Liga for sponsorship reasons, and it has been the highest level of the professional league since its inception in 1901. UEFA currently ranks the league 33rd in Europe. Twelve teams compete in the league, playing each other thrice, once at home and once away. At the end of the season, the top team enters the qualification for the UEFA Champions League, while the runner-up and the third place, together with the winner of the Hungarian Cup enter the UEFA Europa League qualification round. The bottom two clubs are relegated to Nemzeti Bajnokság II, the second-level league, to be replaced by the winner and the runner up of the NB2. The first championship in 1901 was contested by BTC, MUE, FTC, Műegyetemi AFC and Budapesti SC, with the latter winning the championship. Although the two first championships were won by Budapesti TC, the other titles that decade were won by FTC and MTK. In the 1910s and 1920s the championship was dominated by Ferencváros and MTK. In the 1930s, the rivalry between Ferencváros and MTK Budapest expanded with another club, Újpest FC (at that time not part of Budapest). One of the most iconic figures of the 1930s Hungarian football was Újpest's Zsengellér who managed to top goalscorer three times in a row in the 1930s. Ferencváros's Sárosi and MTK Budapest's Cseh and Újpest's Zsengellér were the embodiment of the rivalry of the three clubs from Budapest, named Budapest derby. In the 1940s, Csepel could win its first title which was followed by two other titles in 1942 and 1943. During the World War II there were no interruptions in the Hungarian league. Due to the expansion of the territories of the country, new clubs could re-join the league such as Nagyvárad and Kolozsvár. The second half of the 1940s was dominated by Újpest by winning the championship in 1945, 1946 and 1947. In the 1950s, the dominance of Ferencváros and MTK weakened by the emergence of Honvéd with players such as Puskás, Bozsik, Czibor and Budai.
