He hates the club, but nobody else in Europe would have tolerated his lack of European success - Bayern, Juve etc, and even another Arab club in PSG sack managers for only delivering expected league titles without the UCL.
He refused United post-Ferguson because it was a difficult rebuild job, and obviously the turds Klopp has been polishing at Liverpool wouldn’t be of any use to him, but they’re the two clubs you know he wishes he could have taken over if all the odds were stacked in his favor
He even turned down City until they’d found a way to cheat FFP - interestingly they didn’t appeal when Mangala, Bony, Navas and Fernando were the transfer options.
Everything he’s won at City, he should have - the depth of quality he’s had is unprecedented, and two other managers have also won the title and domestic cups before him, with worse squads.
But because of this, he’s hilariously been stuck there - if he’d have left after 3/4 years as he initially intended to, whoever succeeded him would have also collected the same pots with that talent, putting his ‘achievements’ into context. They’d probably have outdone him in Europe too.
He low key probably wanted UEFA to nuke the club with the FFP sanctions, and likely feels the same way about the ongoing Premier League investigation - an exodus of talent so he can back door it safe in the knowledge that the next guy doesn’t eclipse his relatively moderate success.
