I find it a little funny the fee was only £6-7m. Didn't Bolton call Arsenal's £5m offer "derisory" or something, only a few months ago?!
He's worth about that, though! I mean, is the availability of CBs so dire that Cahill is the answer for a team like Chelsea? Or am I severally underrating Cahill? He's decent, but that's all.
Think Cahill is, as it stands, a better defender than Luiz.
