What? Naw, man, I am portuguese through and through.
Though, I do know some teams from the Brazilian soccer league: Botafogo, Palmeiras, Flamengo, Fluminense, Corinthians, Vasco da Gama (which is the name of a famous portuguese explorer).
Beira-Mar is the main team from the Aveiro district as in their are based in the city. Arouca FC is from a small town a bit to the north and quite frankly not very easy to reach (Sever de Vouga is a pain to get to, I can't even imagine Arouca).
Arouca FC has been quite the success story. They were in the III division in 2007 and in just 5 years they've jumped into Premier League. It is very uncommon for Tier III teams to jump this high.
