The 2019 Copa America has not gone to plan for Lionel Messi and his Argentina teammates. After a shock opening defeat to Colombia, Argentina were held to a 1-1 draw by Paraguay.

It means they have to win their final Group B match on Sunday night against Qatar to stand a chance of qualifying for the knockout stages.

Ahead of their must-win encounter at the Arena do Gremio in Porto Alegre, Argentina went through their paces in a final training session on Saturday.
