I dont see anything wrong in expectations and anticipations. The idea is that always keep doing what you are doing. As long as there is effort being put in then you are bound to expect results and to anticipate it is a good thing. That shows that one has a positive mindset. In the end it's either we win or we fail but we will learn what we might have done wrong if we fail.
You make it sound like there is shame in disappointment. While in my own opinion i know there is no shame in being disappointment. Since it's human we will expect the results to come from we should know that there is limitation to humans and one can be disappointed but thats not the end of everything.
I am pretty sure that's not the same thing. Dude was raised in Belgium football system and then become a football player, many actually do that, and not like he won anything with Belgium anyway, won at premier league which is nice, so did many others, he isn't the only one.
What he needs to remember is that City has been winning for years now, and been good even before he became a coach, he won one with them, the whole "don't shoot" funny stuff, and still winning even to this day, so there are many that won with City not just him, and at the same time there is only one bayern munich job, only one head coach, so it's not a whole 20+ player team, and he got there without showing any type of success beforehand, which is why people think he can't do it. Not that he won't, we do not know, this is Bayern, even I could make them win the league if I get some lucky games, you can too, this is Bayern we are talking about they are the best team, but he certainly doesn't deserve the job.
