Relegation, that absolute sinking feeling after a season of hard-work (depends on the team) and you drop down a level. It's happened to many. Just think of Leeds, Newcastle, Real Betis, Real Zaragoza and so on. But in Brazil relegation is completly different.
2009 saw the Brazilian Série A season end with the traditional four clubs being relegated. No problem there. The sides unfortunate to go down were Sport Recifé, Náutico, Santo André and Coritiba. Ok Náutico and Santo André aren't the biggest sides but Sport Recifé and Coritiba would be considered big clubs. Sport Recifé have a good fanbase in the Northern resort of Recifé.
Ok we will go to 2008. Ipatinga, Portuguesa, Vasco De Gama and Figueirense. Again two clubs not quiet big but two clubs that are quiet big. Vasco De Gama by far the most interesting relegation in 2008. They had big plans but fell down and the fact that Romario was continuing his quest for 1,000 goals the club fell apart. Figueirense big enough but not surprising with relegation.
2007. América, Paraná, Juventude and Corinthians. In this pile we have quiet big clubs suffering relegation. Paraná and Juventude are still to get back into Série A today but Corinthians are very big in Brazil. They went down in 2007 exactly two years after winning the Série A and three years after being taken over by MSI. They are back in Série after running away with Série B in 2008 and have ambitions to win the Copa Libertadores in 2010.
If you go back a few years more you will find that huge clubs such as Gremio, Atletico Mineiro and Bahia went down. The first two did get back up but Bahia, such a big club went down as far as Série C and are currently in Série B looking to get back up.
Relegation in Brazil is different to Europe. In Europe you might have a big name club go down every couple of years but in Brazil you are pretty much guaranteed with a big name or two going down. But the thing is clubs that have gone down don't actually have a good record of coming back up. Just ask Bahia.
