Whether it's Zak or not, McGhee confirmed yesterday that he wants a centre half, which seems reasonable to me. It was mentioned before Christmas that McManus sometimes plays on the Saturday without training through the week and I imagine that has happened throughout his Motherwell career. Heneghan meanwhile has been a consistent performer since arriving but there have been occasions where he would have benefited being withdrawn from the firing line. We therefore need competition for places and in McGhee's eyes, Laing, Kennedy and Ferguson are not up to the job at present.
