Is it simply a case of honing the zonal marking system and getting it right as we have done for sustained periods in the past, or is it time we ditched it and went man to man?
More worryingly, is there little wrong with the coaching or the system, but it's from a PERSONEL point of view that we have a problem? Do we need to buy that mythical "commanding" centre half, and until we do we are going to ship goals?
My take:
I know this much, teams which consistently concede goals from set-pieces don't win leagues. Teams which are poor and porous at the back don't win trophies, even if you do have a spunky front pairing as we do.
We won 3-2 at Bolton with a late winner, and 3-2 at West Ham with a late winner. Neither team will finish in the top six or seven, and I'm extremely concerned that teams such as that can score regularly against us. Against the better teams, we'll face more of a threat than either of these two represent and obviously we'll find it harder to score three times and dig ourselves out of the sh!te as well.
In the short term we've just got to keep working at it obviously. Our only viable option within the squad is the Greek bloke, and with the greatest of respect to him based on the one time I saw him, I don't think he's good enough for a sustained run in the team. Yes he looks like he's decent in the air, but the shortcomings in the other facets of his game mean that while he can do a job, he isn't the answer.
We probably have to work harder as I say on the training pitch, and perhaps look again at who picks up each zone and maybe reconfigure it. I do think Gerrard is more than capable of filling a more prominent role when defending corners, and he reminded us today for his goal (oh sorry kuyts goal

Longer term, as I said before this season started I think our need for a proper centre half is absolutely urgent. If we had a Ferdinand, a Vidic, a John Terry etc etc we'd be six or seven points better per season I should think. The nearest to that in England (and I say this not having seen how he went in the first 20 minutes or so today before he was injured) is Mathew Upson.
More likely though is that Rafa will go abroad to find one, but need one we do I'm absolutely certain of it.
