If he wants to get the best out of Beck then play him up top with Whitehall when fit and a couple of wingers
Going by what Butler said pre and post match, it will be Whitehall and Beck up front in the same formation. If Butler was going to change it and go with Roberts and Carlton out wide, he would have done it Yesterday.
Yesterday was the perfect time to try something new, but seems he has no intention of changing it up. Only way he’ll change it up is if pressure is put on him to change formation from higher up, but apart from that scenario coming about, I can’t see him deviating from this formation.
