Freedman made the comments following Forest’s 2-1 defeat to Brentford away from home at Griffin Park.
The loss has left the Reds 18th in the Championship table, just two points above the relegation zone.
"I'm not concerned at all but we are where we are and we must keep on fighting,” Freedman told BBC Radio Nottingham.
Reflecting on his side’s failure to win against Brentford on Saturday afternoon, the former Crystal Palace and Bolton Wanderers boss said: “We created too many chances not to win the game, but we are not being ruthless enough in front of goal. I am going to have to go back to basics.”
Over the course of the 90 minutes at Griffin Park, hosts Brentford had 55% of the possession, took 12 shots of which five were on target, and earned three corners.
Forest had 45% of the possession, took 17 shots of which eight were on target, and earned six corners.
The Reds will return to Championship action next weekend when they take on Reading at the City Ground.
