Like I said, I though he would have been a great signing then too, and was gutted when we got Nelsen instead: that isn't exactly hindsight offering me a superior insight into Cahill's qualities. As for the 'manager leaving, so cheapness necessary' argument, we're just going around in circles again. Ignoring for a moment that we treated every manager post-Harry the same dismissive way (completely invalidating the premise that we were keeping our powder dry to give to the next bloke), giving up on a genuinely serious tilt at the title because the 'next bloke' might not have liked the signings made to pursue the dream is symptomatic of the ills of this club, and is something we should seriously be talking about more than we are at present, feeble 'we had Defoe and Daws and Gallas' rebuttals be damned.
And besides, I doubt AVB would have wrung his hands in despair if we ended up with Tevez and Cahill as opposed to....erm, no one, because the signings we made instead of those two (Nelsen and Saha) were released before the 2012-2013 season anyway, and seeing as we weren't really interested in giving AVB what he needed in the summer window, I don't think he'd have been too upset heading into the new season with those two in the side instead of their poorer analogues, signed later (Dempsey, ultimately Chiriches).
