Nottingham Forest assistant manager Ned Kelly has admitted that he and his players are "extremely disappointed" by their heavy defeat against Derby County.

Forest lost the game 5-0, as goals from Jeff Hendrick, Johnny Russell and a Craig Bryson hat-trick condemned them to their biggest loss against their East Midlands rivals in 116 years.

"We're extremely disappointed for the supporters who came in huge numbers and gave us great backing," Kelly told the club's official website.

"They were clinical in their finishing but we were disappointed in the manner we conceded the goals.

"We went 1-0 down very early but we thought we were still in the game. We were doing reasonably well before being hit by another sucker punch."

The Reds return to league action on Tuesday night when they face Charlton Athletic.
