Coach Eriksson admitted that the performance of our livewire striker was the major plus point from the loss in Gothenburg.
Starting on the bench, Jermain was handed his chance after just 10 minutes - replacing the injured Darius Vassell - and proved to be England's most prominent goal threat. Anthony came on in central defence at half-time.
"It was good to see some new players on the pitch and of course you have to evaluate them for the future," said Eriksson afterwards.
"I knew before of course that he is a very big talent and in the future he will be physically stronger as well. As you can see he knows where the goal is and I liked what I saw."
Celtic midfielder Alan Thompson was given little chance to shine in his hour on the left of midfield and Eriksson hinted that his chances may be limited when several first choice players return.
"Of course they (Defoe and Thompson) are in my thoughts but as you know I missed a lot of players today so we will see," the Swede said.
Jermain Defoe impressed Sven Goran Eriksson as both he and Anthony Gardner made England debuts in Wednesday night's 1-0 friendly defeat against Sweden.
