Derby boss Jewell fears Liverpool rout
He said: "I don't think I need to remind the lads of what happened at Anfield - 6-0 is a hiding but that can happen in this league if the top teams have a day when everything clicks.
"I remember Ipswich losing 9-0 to Manchester United so it really is scary at times.
"If we defend like we did at Newcastle, we will concede more goals. There has been a lot improvement - but we need to improve even more."
