Easy.How does Caldwell fit into a midfield of Merrett, Shiel, Heppell, Parish, McGrath and now Dunkley?
Surely he reconsiders...
Dunkley, Parish and Caldwell as inside mids.
McGrath and Shiel as inside/outside mids.
Merrett and Heppell on the wing.
It pushes D Smith and Walla out of the midfield rotation completely. Stringer will probably play midfield when Dunkley goes forward.
Plus, we always have injuries/suspensions so there's bound to be some movements
