The former Forest defender made the comments following the Reds’ 1-0 defeat to Preston North End away from home in the Championship on Tuesday evening.
Forest failed to return to winning ways in the Championship, as they suffered a 1-0 defeat to Preston at Deepdale.
Eoin Doyle’s goal as early as the second minute proved to be the difference between the two sides.
Over the course of the 90 minutes at Deepdale, hosts Preston had 48% of the possession, took 10 shots of which four were on target, and failed to earn a single corner.
Visiting Forest had 52% of the possession, took 15 shots of which six were on target, and earned six corners.
Dougie Freedman’s side are 19th in the Championship table at the moment with 14 points from 15 matches, just four points above the relegation zone.
The Reds are back in action on Friday evening when they take on Derby County at the City Ground in the Championship.
