As far as I can tell, he's just horrible defensively, maybe as a footballer, his positioning is beyond abysmal. Some players really do suck for a bunch of games till fit but he's had quite a few now. You don't have a huge number of choices till Jan but I think Newcastle need to already be thinking about shipping him out even if on loan and bringing in a top CB. I think Colo, fit and with a top CB alongside him can become really good again, but one terrible CB will make the best CB alongside him look retarded. They play completely as a pair and everyone but Colo is ****, Taylor on his day can have a good game but even ignoring fitness those days are few and far between. Though I do find his "it wasn't me" acting to be pretty entertaining, particularly when he's handballed it.
