As I do not feel that it's realistic or practical to offload four or more defenders in one shortened window and to expect suitable replacements.
It's been difficult enough to find quality defenders as it is, therefore to dilute our time four or five times (add time of expenditures) is naive.
Ideally, I would keep Coleman long-term while Baines, Jagielka and Keane or Mori in the short-term and have another season at the club.
I would then focus on looking for one or two quality central defenders and after that, if money is available, strengthen at left back.
