i think we should buy a LB, instead of moving our best CB to LB, but that's just me. (we also need a backup RB, maybe lansbury can do it? feels like we're wasting a useful talent there)
i also think another manager would get more out of djourou, who has been our best defender for prolonged stretches, and is in a horrible run of form. while i'd like to have bartley as 4th choice instead of squillaci, i understand sending him out on loan so that he comes back a fully-formed player with no need for development.
frankly, i think changing the coaching would have more of an impact than making a signing. but in midfield and attack, we definitely need some big, big signings.
