A World Cup without Lionel Messi? Argentina have one game to save their campaign

Lionel Messi and Argentina have one game to save their World Cup qualifying campaign - how did it come to this?

With one game remaining in South American qualifying, Argentina are in danger of missing their first World Cup since 1970 after they were held to a goalless draw against Peru on Thursday.
Argentina - who sit fourth in the latest FIFA world rankings - head into their final match with Ecuador having won just two of their last 10 qualifiers and sit in sixth, outside the fifth-placed playoff spot.
