I am assuming with the signing of another full back we plan to use NG or Pickering as cover in midfield ? Or Perry as is widely speculated could be on the move to Villa today ? Which would mean we still require a body for midfield. With Jones injury being ligament he is likely to be out for many weeks and with Greens age he is likely to pick up 1 or 2 more niggling injuries we would be left extremely short if NG was to move on.
