"The drop-goals are always planned, it is a great weapon for us," Ford said.
"We have had a bit of a rocky build-up to this World Cup but I think in the last 10 days there has been a different feeling to the place."
The Pool D match had been billed as a massive challenge for England against a Pumas side who beat them at Twickenham last November.
It was the fourth time in the last six games that England had had a man sent off.
We have many World Cup first-timers and they will take a lesson of how we need to be ready when the whistle blows."
