Nottingham Forest were thumped 3-0 at Derby County on Sunday afternoon.
Philippe Montanier's side brought a three-match winning streak with them to the iPro Stadium but the Reds were brought back to earth with a bang.
Nicklas Bendtner's own goal on 33 minutes started things off, before second-half efforts from Tom Ince and Will Hughes completed the rout for Nottingham Forest.
Victory would have seen them move within four points of the top six but the seven-point deficit remains after 20 Championship matches played.
It was a bitterly disappointing way for Nottingham Forest to lose an East-Midlands derby, but in truth it was a rather shambolic defensive outing from Montanier's side.
Stan Collymore spent two successful years with the Reds toward the beginning of his playing career, and the 45-year-old admits that he is not happy with how the way things went away to their local rivals yesterday afternoon.
Not happy. It's a Derby game, don't compete on the basic local rivalry level. Credit to Derby, they did. Gutted. https://t.co/ns3wDCec4s— Stan Collymore (@StanCollymore) December 11, 2016
Nottingham Forest host Preston at the City Ground on Wednesday, before then hosting Wolves next weekend. The next few matches could shape Forest's season and whether Montanier's boys will finish in the playoffs or not.
