The quarter-finals of the 2011 Copa América begin on Saturday afternoon, and in my latest piece for ESPNSoccernet I take a look at the final round of matches in the group stage, during which a previously slow-burning (if interesting) competition really sprang into life. Sergio Markarián’s outburst, the awful state of the La Plata pitch, and Venezuela’s incredible campaign so far are all covered, among many other things. Enjoy.
