We should be spending a bit of money on a centre back that Is better than any of our defenders.
But bringing back O'Riordan will leave us with Miller, Pratt,McLoughlin, Wharton and Carter 6 centre backs. Doesn't feel like they will look to bring in another defender which will be a mistake. Unless O'Riordan is being brought back for us to have a look at him and if we do sign an experienced centre back will then be sent back to Doncaster for the rest of the season. Or if Carter or Wharton are expected to be out longer term. I just don't see them having 7 centre halves registered in the squad and be harsh now to leave Pratt out in favour of O'Riordan
