Lionel Messi fits in final training session with Argentina ahead of decisive 2019 Copa America match - in pictures

Lionel Messi and his Argentina teammates face a date with destiny in Brazil, knowing anything less than a comprehensive victory over Qatar could see them suffer an embarrassing group phase exit from the 2019 Copa America. Argentina suffered a shock 2-0 defeat to Colombia in their first Group B match and were then held to a 1-1 draw by Paraguay in their second, with Messi failing to shine in both. He was by no means alone in that regard; a squad boasting the likes of Sergio Aguero, Paulo Dybala and Angel Di Maria have all failed to shine at the Copa America so far. A victory over tournament guests Qatar coupled with a defeat for Paraguay against already-qualified Colombia would see Argentina through automatically to the last eight. If Paraguay get a result against Colombia, Argentina's only hope of reaching the knockout round will be as one of the two best third-placed teams, making a decisive victory over the Asian champions imperative.
