I think he doesn’t go looking and it’s generally accepted he’s happy and not looking to leave. How many approaches do Man City get for Pep? Doesn’t mean he’s not a manager others would want.
I think he is very happy here, I also think he realises that any club coming in for him would likely be doing so to replace the manager they’ve just sacked, that club would very likely be in the midst of falling fortunes and that club would be looking for a near immediate solution to their problems and a marked improvement in form and results.
He could easily take another job and find himself sacked after 20 odd games.
He seems to oversee the footballing side of the club completely, he carefully and patiently puts in place all the building blocks required to keep moving the club forward, probably why he always appears so calm ’nothing is ever wholly dependent on our next result, not even a play off final at Wembley.
It‘s a long term project for him and the majority of the fan base have fully bought into it.
For evidence of this look no further than 25,000 + rocking the CBS Arena every home game.
