Forest won the East Midlands derby 1-0, thanks to a fifth-minute goal from Nelson Oliveira.
Former Derby and Notts County midfielder Ramage was following the match, and he was impressed with how the Reds kept their discipline in the first half.
“Forest have been very disciplined,” the 45-year-old told BBC Sport. “I never thought they had that in their locker, but they've done well. Derby have lacked creativity in and around the 18-yard box.”
Ramage said after the game: “It hurts. I feel for the Derby fans behind the goal too.
“The fluency wasn't there and we didn't have midfield runners. They just didn't have the legs and looked jaded and tired.”
Over the course of the 90 minutes at the City Ground, hosts Forest had just 34% of the possession, took 15 shots of which four were on target, and earned two corners.
Visitors Derby had 66% of the possession, took 14 shots of which only two were on target, and earned five corners.
Forest are now 15th in the Championship table with 17 points from 16 matches, seven points above the relegation zone.
Derby remain fifth in the standings with 30 points from 16 matches, a point behind leaders Hull City, who will face Middlesbrough at the KC Stadium this afternoon.
