I was actually thinking Millwall and that's even before today's result. They may also struggle to keep hold of their best players in January and so could start a steady decline. The only trouble being that they may already have enough points to keep them afloat.
Birmingham or Bolton. There is always one recent ex-Premier side that gets sucked in and usually goes down. We could also do with someone going into admin, though no-one looks on the brink this season. Bristol City maybe?
Millwall have the dubious distinction of the side with the highest points total at xmas ever to get relegated. Surely they can't manage that again?
I reckon Huddersfield and Burnley will be in the thick of it come the end of the season. In turn I reckon Ipswich and Birmingham will pick up form.
