When the Spanish come to the valley
The defences will be solid
A Breton giant will lead the charge
And a man from the west will rule.
But Oh, the woe that will befall
The speaking man will become silent
The clocks will cease from marking the hours
And death death death death doom.
It's pretty clear what's going on in these lines. At first it seems we might be talking about a military campaign, but that mention of "The valley" means "the Spanish" can only refer to Tony Jimenez. The "Breton giant" is obviously Yann Kermorgant, and the man from the west is an oblique reference to Chris Powell's heritage. All looks good so far, yes? How wonderful that Nostradamus could have predicted Charlton's resurgence under Chris Powell so clearly!
But then, there's a dreadful prediction. "The speaking man" is a clearly a reference to the head of communications, who has indeed just become silent. When clocks mark the hours, what do they do? Of course they strike, and so we realise that Nostradamus foresaw Charlton's lack of a regular striker.
The last line is far from ambiguous.
So, there we have it. The people who are predicting disaster for Charlton (as they always do at this time of year) aren't just acting out of ignorance and pessimism (as usual), they're heard of this prediction. For once they're not talking uninformed nonsense, but are basing their statements on solid, ancient wisdom. And I, for one, am terrified.
