Porto Alegre (Argentina)
Gre-Nal
Gre-nal is the largest derby in the southern region of the country.
The match is played in Porto Alegre, home to both teams (Internacional and Grêmio), but the teams' support bases are evenly distributed all across the state of Rio Grande do Sul, home to 11 million people, as well as neighboring states. The match happens either at Olímpico Monumental Stadium (Grêmio) or Beira-Rio Stadium (Internacional).
Grêmio has more international titles and fans in the state, but Internacional has more fans in the city and was never relegated to second division, as well as having a few more regional titles. The rivalry extends back to 1909, in the same year Internacional was founded, when Grêmio beat Internacional by the score of 10-0. Some would argue it began earlier, before Internacional was founded, because its founders were actually rejected to join Grêmio, which at the time (first decade of the 20th century) only accepted members of German nationality or ancestry.
