It would probably work best with just smith and runners but I wouldnt for a second drop Derbyshire or play him deeper, in an ideal world Derbyshire, Smith and Baxter could all play in the same side and if Derbyshire is clever enough in his movement which I belive he is and was willing to sacrfice scoring goals for the team it would be even better if he makes runs all over the box when the ball comes in drags a CB marking him away allowing space for Baxter or the wide man from the other side to get in the box and to score goals
In reality that requires them all to be on the same wavelength and good communication as well as Smith to nod the ball down into the right areas, bloody hard to do but not the most coaching in the world. A simple move that looks like its direct football but its actually clever coaching, Big Sam teams as much as I hate him do it very well and thats because someone like Nolan is a willing runner and gets double figures as a result often
