Forest beat Birmingham City 1-0 on Tuesday night, despite making five changes from the team which won at Queens Park Rangers at the weekend.
It was a result which highlighted the quality at Freedman's disposal this term, and the 41-year-old says he was pleased to discover that he is able to alter his starting XI without impacting on the quality of his line-up.
“I know now that I’ve got a bench who can help me either win a game or hold on to a game," he said.
"I’m sure everybody else was questioning it [the line-up] before the game but I’ve got the opportunity to see the players working every day and I have the mindset that you need a squad in this division."
Forest grabbed the win at St Andrews thanks to a goal from Dexter Blackstock in the second-half.
The Reds set-up to limit Birmingham's chances and their organisation was evident throughout, with Blackstock's strike also highlighting their threat going forward.
It was the second away win that Forest have picked up in succession, following the aforementioned QPR success on Saturday, and Freedman will no doubt be very satisfied with the progress that his squad are making.
The Reds started the season inauspiciously, but they made a number of additions in the latter stages of the transfer window and beyond, and the increased quality in the group is now starting to shine through.
Forest currently sit in eighth place in the Championship table, and face Middlesbrough looking to make it three wins out of three at the weekend.
