Wanderers have scored in 14 of their last 16 games but their ability to convert chances has come under scrutiny this season, particularly at the Reebok.
Freedman will be without his top scorer Jermaine Beckford this weekend at Reading and so David Ngog is likely to shoulder the goal-scoring burden alone up front.
But the Whites boss says he is trying to get more goals out of his side by giving his players prior knowledge about when they will be in the team and when they will be rested.
Asked how he could rectify the number of chances his side were currently wasting – Freedman revealed his rather novel approach.
“When you get in and around the box you have got to work on instinct,” he said.
“Instinct is a very difficult thing to coach. But what you can do is try to give players belief that you won’t be dragging them off after 50 or 60 minutes.
“I tell all my strikers ‘you will be playing the next six games at 90 minutes’ or ‘you will play the next four games at 90 minutes,’ so they feel a bit more relaxed.
“You have got to believe in yourself, you have got to believe in the style of play, you have got to believe in your training and you have got to make sure the players believe in you.
“Hopefully, that then turns into goals.”
