Lambert: Celtic can't sack O'Neill, he'd have to walk

Paul Lambert says Celtic cannot sack Martin O'Neill and that the manager would have to walk away himself. The former Celtic captain told BBC Sport he would not be surprised if O'Neill left the club, but he would be shocked and disappointed if it ended in a sacking. Lambert, who played under O'Neill at Celtic, framed any exit as the manager's own call rather than a board decision.
