I realise you're not suggesting that the charges were timed as an attack when City were weak, but City's position at the time of the charges was totally irrelevant.You really have to remember the timing of the charges. City were “struggling” by their recent standards and Pep had expressed his public displeasure and Arsenal had a good lead in the PL. United were even talking about a possible “quad”. The announcement was framed for maximum damage, the press was being briefed while City were still being informed about charges. They had zero expectation that City would land a pure treble at that point - it was thought more likely that Pep might walk away. I suspect the PL are now a little conflicted. Watching Masters’ performance at the HoC committee was an eye-opener - he was so unbelievably lightweight. Can’t see him surviving.
Football seems to be rapidly globalising and City happen to be sat right at the top of the tree, so I agree with your general point - though that was not how they thought things would turn out for one second. But, the die is now cast and they have to deal with it. Add the known geo-political realities into the mix (Mansour at the Coronation, Mansour with Erdogan in Istanbul, multi-billion UK investment pipeline etc) The PL is in way over its head.
They were clearly timed in relation to the Govt White Paper discussing an independent regulator for football, which was due just a few days later.
