Sampaoli's success sparks optimism in Argentina

BUENOS AIRES - A year out from the final World Cup of Lionel Messi's prime years, Argentina is beginning a new era as Jorge Sampaoli attempts to turn around the two-time world champion's faltering qualifying campaign.

Sampaoli's first match in charge since leaving Sevilla to answer his country's call gave cause for optimism as Argentina saw off an under-strength Brazil 1-0 in Melbourne on Friday.

But there's a long way to go for Sampaoli to turn an underperforming unit into the World Cup contender it should be, based on the talent at its disposal.
