In the following season, a second nationwide competition named "Campeonato da Primeira Liga" (English: Premier League Championship), or simply Primeira Liga, was provisionally established by the national federation to increase the number of matches per season and improve the competitiveness of Portuguese football. As the regional champion, Porto qualified for the first edition of the new round-robin competition, winning it with 10 victories in 14 matches. Due to the success of its format, the Primeira Liga was made an official championship competition for the 1938–39 season – its name changed to "Campeonato Nacional da Primeira Divisão" (English: First Division National Championship) or simply Primeira Divisão – and replaced the Campeonato de Portugal, which in turn was converted into the Taça de Portugal, the main domestic cup competition. Porto won the inaugural edition of the new league championship and successfully defended the title in the next season, despite almost failing to take part. The club failed to secure a third consecutive title, and after nearly missing again a place in the Primeira Divisão in 1941–42, it would only return to a top-three finish in the 1946–47 season. In 1948, Porto defeated English champions Arsenal 3–2 in a friendly match. To commemorate this victory, the associates offered the club a massive trophy made of of silver and wood – the Arsenal Cup.
