A win for Derby here would smack of trying to shut the stable door when the horse has long since bolted. Forget the maths. It doesn't need Johnny Ball to tell you that they are down and even the most ardent County fans are planning ahead to next season and possible trips to Carlisle and Doncaster. Sunderland though are well in with a shout of beating the drop, and a win here would put clear daylight between themselves and the bottom three.
