Argentina produced one of their best performances in recent times on Sunday with six different scorers getting their name on the scoresheet in a comprehensive 6-1 friendly win over Ecuador in Spain.
Lucas Alario put them 1-0 ahead in 20 minutes with a powerful header from an Acuna corner, then seven minutes later Jhon Espinoza deflected a cross from Acuna past his own goalkeeper.
Substitute Angel Mena cut the deficit for Ecuador three minutes into the second half with a spectacular free kick but any hope of pulling back their rivals was short lived.
The result capped a positive few days for Argentina, who fought back from 2-0 down to secure a 2-2 draw with Germany last week.
The South Americans are now unbeaten in five games since losing the Copa America semifinal to Brazil in July.
