We need a keeper, a centre half, a winger and a striker. If that requires ditching O'Donnell and playing Grimmy or Maguire at right back to free up funds so be it.
Getting rid of Long as suggested above would send the correct message that more is expected from the squad. Lasley or the new manager needs to sit down with Liam Polworth and explain that he is heading back to the Championship one way or another if he doesn't get his finger out. If he doesn't pick up this month get him out the door as well as he's a man down at the moment.
