Internacional plays in the Campeonato Gaúcho, the state of Rio Grande do Sul's premier state league, as well as in the Campeonato Brasileiro Série B, the second highest tier of the Brazilian football league system. They play in red shirts and white shorts and socks, the first of which give the team its nickname of Colorado (The Red). The team's home stadium, known as Beira-Rio" ("Riverside"), was one of the twelve 2014 FIFA World Cup venues and has a capacity of 51,300.
Internacional is ranked first in Americas and sixth in the World in number of paying members, with more than 104,000. Internacional were South American champions in 2010, winning their second Copa Libertadores title. 2006 was the most successful year in Inter's history as they won the Copa Libertadores and the FIFA Club World Cup, defeating European champions Barcelona in the latter and South American reigning champions São Paulo in the former. Other international titles include the 2007 Recopa Sudamericana, the 2008 Copa Sudamericana and the 2011 Recopa Sudamericana.
Internacional has a rivalry with Grêmio, also a club from Porto Alegre, and the two sides contest the Gre-Nal derby, considered by many fans and commentators alike in Brazil to be the fiercest in-city football rivalry in the nation.
