Not sure the tweets were to damage City. Having some successes in the APT case is wholesome praise the way the press has been going.
But yes, the shift of the narrative away from filing accounts that don't show a true and fair view (which absolutely is one of the allegations and is THE most serious) to Mancini (which should be time limited) and Toure (of which half should be time limited) is interesting. I read the actual article (linked for anyone who wants to read it) and the paragraph about the allegations has nine words about accounting and nearly 50 on Mancini and Toure. Almost as if the ground is being prepared for some non-disclosures to the PL and not the more serious stuff. It may mean something if you think Ziegler understands what he is writing about, but that is a stretch, imho.
