Yes.
Aa re Pep's complacency.
Apply it to other elite genii in sport.
Would they change/compromise or believe in themselves. That's what sets them apart. The others in the club stopped (for whatever reason) doing there jobs at as high a level. A real drop off.
Mourinho, Wenger, and Ferguson are classic examples of stubbornness. They didn't change or compromise, their time just ran out.
Ferguson knew it, and stepped down. But he still wanted to be (and made sure he was) the major influence at his club, to it's detriment.
Wenger knew it, and walked away from Arsenal, leaving matters to his successor.
Mourinho never had the same level of power as Ferguson or Wenger at any of his clubs, but, like Pep, he has left an indelible mark of 'genius' on all of those he has been involved with.
Nothing lasts for ever. All great managers/coaches have a shelf life, but some realise and get off before they get too close to the edge of the shelf.
Pep knew when it was time to leave Barcelona and (after a break) went to Bayern. Throughout his three years there, he worked within a rigid structure that was not of his own making. As such, the opportunity to join City with almost absolute freedom to create an empire was one he couldn't turn down.
The City Board has 100% faith in Pep. There's no way they'll sack him. As such his future at City is entirely in the hands of Pep or the Grim Reaper.
When he does leave, I'd prefer him to do it like Wenger than Ferguson, and hope that he doesn't stay long enough to turn into crazy Mourinho or, heaven forbid, Malcolm Allison.
