Virtually everything you wrote here is arrant nonsense, though some of it at least has comedic value.
To the extent that this 'under resourced' squad which he spent half a billion euros on, was bad (which it was) the guy sanctioning eleven deals should take at least
some (if you wanna be charitable) of the blame for, but not in your book, it's everyone else's fault but Mourinho's.
The Pogba bit is hilarious. "It's clear he was a virus all along!". Remind us again who was it that bought this virus? Mourinho talked this guy up, sold a bill of goods to the club, and made them break the transfer record for him (even though he's got bad blood with us already) and then a year later he, without breaking stride, proclaims he is a virus. 'I'm tired of this toy I've talked up previously and now get me some new toys".
This idea that Victor Lindelof, a player he (Mourinho) brought from the Portuguese League, using his own scouting network was somehow 'imposed' on the manager, pretty much sums up the general stupidity of your reasoning.
He 'doesn't like to develop young players'
It's like when Bill Murray says "I don't play defense" in Space Jam. Any abnegation of responsibility is fine as long as the person just says he doesn't like it. Actually, despite your best efforts to defend the indefensible, Mourinho disagrees with you, whenever he brings up a list of facts that includes all the stellar youngsters he has brought through over the years (featuring Davide Santon et al.).
Lukaku's problem wasn't that he was 'not serviced enough' it was that he is a goal poacher, and Mourinho doesn't use poachers. He hoped for another Drogba, but Lukaku is not very similar to Drogba at all, despite the fact that it is who he idolised as a teenager. So that's another stupendous waste of money, thanks to the manager who demands ever more.
It's funny, it's not even just Mourinho. Virtually every manager does this spiel whenever they fail. Moyes didn't sign who he wanted to, neither did Van Gaal; Conte just isn't given enough money at Inter etc and so on. From their perspective, churning out this propaganda about it being everyone else's fault but theirs is understandable. It's being a 'clever cnut', protecting your reputation so as to get the next well payed job, but surely, not even in their wildest dreams do they expect some cretins to actually lap it all up, every last word of 'it's everyone else's fault but mine', but then as you prove, sometimes they just strike gold.
To contend that Mourinho played second fiddle to the board is naive at best, but to claim he played second fiddle to pundits and fans is farcically absurd. Thanks for making us laugh.
The amount of mental energy spent over who was right in terms of fan narratives is astounding. Hopefully at least on some level, you do realise that none of this stuff people write on an internet forum has any effect,
whatsoever on any manager or the work they are actually doing.
