Defending must improve - Ferguson

North End were subjected to a thumping 5-3 defeat at Pride Park on Tuesday after a series of mistakes which left Ferguson fuming.The Scot accepts his men cannot afford to gift high-flying Newcastle, who returned to the top of the Championship with a 4-1 win over Coventry, the same opportunities on Saturday.Ferguson said: "We know what Newcastle are all about, and I'm not a negative person by any stretch of the imagination, but if we defend like we did at Derby, we're going to be in a battle."We're aware of that, and we'll get back to training and keep working as much as possible, but we know it's going to be a difficult game at Newcastle."
