Derby's wretched season reached a new low on Saturday as they were beaten 5-0 by West Ham in Saturday's Premier League clash at Pride Park.
Although they had suffered bigger beatings at the hands of Liverpool and Arsenal this season, it cannot get worse than a home drubbing at the hands of a decimated Hammers outfit.
Alan Curbishley's men move up to ninth after by far their biggest win of the season.
It took until 42 minutes for an unmarked Lee Bowyer to begin the rout, sweeping home after Carlton Cole nodded down Nolberto Solano's cross.
Three goals arrived in eight minutes soon after the restart - Matt Etherington firing home after exchanging passes with Bowyer, Eddie Lewis scoring an own goal after a Jonathan Spector strike, and then Bowyer netting again from a Cole cross.
Solano sealed the win with a free-kick into the top corner.
