Paul Clement has described Derby County's defeat to Nottingham Forest in the Championship as a "reality check".

The Rams slipped to their first defeat in 11 matches after Nelson Oliveira handed the home side the lead inside the opening five minutes.

The head coach told BBC Radio Derby: "We're to blame for not getting the right result tonight for the way we played. We lost a bit of identity.

"We were unable to create the chances we have in recent games, which was disappointing. It's a reality check for everybody. What we'll need to do now is reflect on it and get back to our way against Cardiff."

Derby sit fifth in the table following the loss.
