Derby County manager John Eustace has demanded the Rams' channel their anger from their no-show at Oxford into their another crucial encounter against Norwich City on Tuesday evening.
Both clubs are teetering on the edge of the Championship bottom three and struggling for wins with only three between them in 20 games this season.
Derby, leapfrogged by Oxford after their 1-0 defeat at the Kassam Stadium on Saturday, lie 21st in the table.
"We were all very angry about the performance. We let ourselves down on Saturday. We all know that," Eustace told BBC Radio Derby.
