Boca Juniors win its 3rd league title in the official AFA league while San Lorenzo achieved its first title ever at the top division winning the AAm championship.
Asociación Argentina de Football - Copa Campeonato
As Boca Juniors and Huracán both finished with 51 points each, they had to play a best-of-three playoff to decide a champion. Palermo, which had been relegated from the Asociación Amateur, joined Asociación Argentina remaining at Primera División. Argentino de Quilmes returned to the top division after being relegated in 1918, while All Boys, Argentino de Banfield, and Sportivo Villa Urquiza made their debuts in Primera.[2]
With the third match drawn on points (there was no goal difference rule), a playoff was held, finishing 0–0 after extra time so a fourth match –to be played to a finish– was required to determine a champion.
^ abFrom 1921 to 1925 there were two teams called "Platense" due to an internal conflict in the lists of candidates for president of the institution. Current Club Atlético Platense played at the dissident Asociación Amateur and the other squad (known as "Platense II") played in the Asociación Argentina.[3]
