Pep first love will always be Barca.
The reason most people don't stay with their first love is because they grow up and realise it was a relationship built on proximity. You meet what you think is the most perfect partner in the world, and massively coincidentally out of the 8 billion people here, they were the one who went to the same school or work or pub or whatever.
Then you grow up and travel and move and meet people and realise that actually that was all pretty dumb and there's much better suited people for you out there.
That's Pep and Barca. He's a Catalan who came through their Academy. It was probably a dream come true to successfully manage them but he found out about the politics and the stress and the backbiting and the rest. Now he's at a highly professional club ran by the best executives and owner in the world in the best league in the world and is surrounded by people who trust him rather than undermine him.
While I'm sure Barca is his first love, City is where he most wants to be. There's a reason he's stayed here about twice as long as any other job he has held. He fits us perfectly and we fit him perfectly and he seems to understand this. Like most workaholics, he gets burned out at the end of the season and starts thinking about packing it in and then he goes and sits on his hands for three months and he's absolutely bursting to get back into it.
My United mate (proper fan, not one of those tossers) has said since Pep joined that he could do Ferguson length tenure here because there's literally no better club for him to be at. I never believed him but I'm starting to. Compare trophy lift Pep to pre season Pep and it's like looking at a different person. I think he will extend again.
