Why do the Blades have to be mentioned in the headline? The fact is that Warnock is a former Millers' player and that is pertinent to the story and his affinity with the club. It's got nothing to do with him being a former Blades' manager. How about 'Former Miller In Running To Take The Helm' or wouldn't that sell the newspaper?!
Can't see why he would be interested. Firstly he lives the other side of the country and I hear his wife is not so well at the moment. Secondly he can't need the money or the hassle. Unless his wife has told him to go and have one last football fling.
