An early goal from Villarreal left-back Pervis Estupinan fired Ecuador to a 1-0 win over Nigeria in their friendly here on Friday. Estupinan met an Angel Mena set piece with a downward header at the far post that left goalkeeper Francis Uzoho with no chance. The South American outfit were mostly content to sit back thereafter as they eased to a victory that never seemed in doubt at Red Bull arena. Ecuador will continue their preparations for this year's World Cup with friendlies against Cape Verde and Saudi Arabe over the next week.
