“The Copa Libertadores can seem like a slow burner, but it is about to catch fire. The final group games are taking place in South America’s equivalent of the Champions League. Next week, the 16 remaining teams kick off the knockout stage. Come June 1, just two are left standing — and it is a fair bet that one of them will be from Brazil. In the last 20 years, only three times has the final not featured a Brazilian club.” SI Tim Vickery
