Giggi Riva and friends,
I attached here an excel file with 8 possible squads from Brazillian teams (1920-25 and 1925-30). Not all of them are complete, but at least we can have a "full" bench. I also attached the pictures I found (almost all players listed are there). If you have problems translating the subtitles, I can help you. I listed 8, but if it's too much, I am going to list here the reasons why I chose these teams ( 4 from São Paulo, 2 from Rio de Janeiro and 2 from Minas Gerais) and in the order of my humble opinion:
Paulistano 1925-30: the first great brazilian team with 11 Paulista titles in the first 30 championships (or so). Besides, Friedenreich played there and it was one of the first succesfull brazilian team overseas
América MG 1920-25: 10 times Mineiro champions in a row (1916-25)
Corinthians 1920-25: 6-time Paulista champions in the decade, including 3 in a row (1922-24). Neco is one of the greats in the team's history
Palestra Itália (from São Paulo state) 1925-30: 2-time Paulista champion in a row (1926-27), including a historycal win versus 100 goals Santos in 1927 "final". Besides, Heitor, Palmeiras (Palestra Itália had its name changed to Palmeiras due to WW II) topscorer until now, played for this team
Flamengo 1920-25: 2-time Carioca champions in a row (1920-21) and 3-time runnerup in a row (1922-24).
Santos 1925-30: Altough never champions, in 1927 they scored 100 goals in 16 games. Its attack had Feitiço and Araken
Vasco 1925-30: Champion or runnerup of Carioca from 1926-31 (except 1927).
Palestra Itália (from Minas Gerais state) 1925-30: after America MG dominance, and also having suffered it biggest loss to the rival (Atlético MG 9x2), they won 3 Mineiro championships in a row (1928-30) in the first decade of the team's existence (like Palmeiras in São Paulo, some years later they became Cruzeiro)
