The only justifiable reason for not removing LVG from his post back in December (or whenever the decision not to let him see his contract out was made), is – well – actual faith in his abilities. You believe he can turn it around, and that he can meet whatever demands he's supposed to meet as per the terms and goals agreed upon. If you don't actually believe that – you sack him and replace him with the best possible alternative, whether that be a short-term or long-term alternative. What you don't do, is to install the done-for bloke as caretaker for the rest of the season. That makes absolutely no sense on any level.
So, for me at least, it rings very odd when people say: “Yeah, but there was no point in sacking him, because Giggs was the only alternative.” What? If that's actually true, we're in deeper trouble than most suspect. We let LVG stumble and fumble along because we couldn't think of a single half-plausible caretaker candidate beside Ryan Giggs (who didn't want the job). Well, I refuse to believe that. There's incompetence and there's...I don't know, pure lunacy? Woody isn't a maniac. If he'd concluded back in...whenever it was, that LVG had lost his mojo and his ability to do the job properly – he'd have let him go.
So, what we're left with – if we insist on Woody's sanity – is a scenario in which LVG continues to be genuinely backed by his employers (who believe he isn't doing badly enough to warrant a sacking) – but at the same time has been effectively replaced already. Presumably because the same employers do not feel that letting LVG see out his contract is in the best interest of the club.
That is a pretty odd state of affairs, one could say. But it could very well be close to the actual truth of the matter.
