The first meeting between Porto and Sporting CP occurred on 30 November 1919, during a friendly tournament organised by Porto. Their first official encounter was in the first leg of the final of the inaugural Campeonato de Portugal in 1922, which Porto won 2–1 en route to its first national title. Since then, the clubs have met in 221 official matches, with 80 wins for Porto, 78 for Sporting CP and 63 draws. Despite the rivalry, both clubs formed an alliance against Benfica in 2017.
