Delph is the only player we have who runs through the centre of the park and takes players on, something we didnt have in the MON era and caused us to be awful at breaking down teams who in front at VP.
Obviously, he isnt always successful but its nice to see. However he isnt defensive enough to be in there as a stopper, isnt creative enough to be a playmaker, and doesnt score enough to be a threat for the oppo. In short, he doesnt bring enough to the team to be anything more than a solid squad player. He isnt starter material.
