Ecuador may feel hard done by after finishing on level terms with Brazil in the teams' Group B opener in Pasadena, California. A Miller Bolanos cross appeared to bounce off Brazil's Alisson and into the goal, but referees disallowed the goal.
Here are three takes from the match.
1. All square in battle of the flanks
With the power of Luis Antonio Valencia and the pace and subtlety of Jefferson Montero, Ecuador have a terrifying pair of wingers, backed up by attacking full-backs in Juan Carlos Parades and Walter Ayovi. Brazil have Willian and Philippe Coutinho wide, with Dani Alves and Filipe Luis providing the support.
