I think Hill will be rested soon and it will be up to OO to keep the place. We shouldnt play Hill and Dunne together is possible.
Clint Hill has been replaced so many times over the last couple of seasons it is ridiculous, but there he still is, leading the team out onto the pitch every week. I understand your reservations about playing Hill and Dunne, but this guy will have to be special to keep Hill out of the first team.
