People do change as they get older and he is naturally a different man and manager now than he was in 2004 but at the same time, I think there are fundamental things within people that will always be there and there are elements of his personality that have not and will never change.
Familiarity breeds contempt and complacency as well, the way people almost brushed off the fact he won the PL last year says it all, ten years previously we were talking about him doing exactly the same thing as the greatest thing that has ever happened to the club. Plus the more you win, the higher the standards people judge you by and the more unrealistic expectations become, look at the backlash Guardiola had with Bayern as well for further evidence of that.

I hope you're right but I'd be amazed, I said the day we sacked him that he'd win the PL again before we do.
