Former Liverpool striker N'Gog came off the bench to net the winner in Freedman's first game as manager against Leicester before collecting a pair of yellow cards to be sent off in stoppage time.
After sitting out the scoreless draw with Leicester, the 23-year-old was restored to Wanderers' starting line-up at Blackpool on Saturday with Freedman harbouring no ill-feeling over his dismissal a week earlier.
"I want David to play that way - I don't want this playing at 90 per cent," said the former Crystal Palace boss. "He's got to go and play. His character's formed, he is what he is. I'm not going to change him.
"I'm here to try and give him ideas. He's a talented boy and I want him to be who he is because I think if he shows us who he is as a man and does what he does then there's goals in there.
"If there's going to be goals in there then we're going to be reaping the rewards. So more of what I've seen would be my message."
