The Copa Libertadores Second Round kicks off on Tuesday night as the biggest sides in South America begin their assault on the famously difficult continental trophy.
Given their considerable financial advantages, Brazilian sides will once more enter the competition as pre-tournament favourites and, with six entrants in 2013, the odds will once more be stacked heavily in favour of the country to supply the competition's eventual winner.
Brazil supplied winners for both of the continent's major trophies last year, and will be determined to stamp their authority with a third consecutive Libertadores title success.
Reigning champions Corinthians will be joined by Copa Sudamericana victors Sao Paulo and national title holders Fluminense and Palmeiras. The quartet will then be joined by both Gremio and Atletico Mineiro.
So, with the tournament about to get underway, let's take a look at Brazil's potential champions.
