The 57-year-old Albiceleste coach was delighted with his striking duo as they put La Roja to the sword in Santiago to keep them top of the South American standings
The 2-1 victory, courtesy of Goals from Barcelona's Lionel Messi and Real Madrid's Gonzalo Higuain, keeps the Albiceleste top of the standings heading into the next round of fixtures next March.
And Sabella believes they find themselves in this position because of the firepower he has at his disposal.
"We have forwards of huge standing who normally never forgive mistakes," Sabella told reporters.
"We knew Chile would take the ball from us a lot and we had to be very concentrated in defence."
The defeat leaves La Roja languishing in the bottom half of the qualifying table with 12 points from nine games but the Argentina head coach insists it is too early to tell how good they are with injuries and suspension hampering Claudio Borghi's men progress so far.
He added: "[The Chile team] have excellent players to reach the World Cup, they just can't be classified yet, as some of their players are injured and/or punished."
Argentina's next game will be an international friendly against Saudi Arabia on Wednesday, November 14.
