Looking at the championship table, I can't see it being Boro as they seem to have plenty of goals in them.
Blackburn and Millwall are two sides that look like they would push on with a few more goals up top, neither is that attractive.
Avoid Coventry or Plymouth (shit managers who would be no good for him) or Albion (no explanation required).
Maybe somewhere like Luton, Derby, or Sheff W.
