Seems standard for Barca and Real, not that I disagree with you. Unless you are winning everything all the time and looking amazing doing it, you're on thin ice with those two.
Now, I'm no expert in European football. I feel like I know what I need to know in the grand scheme of things, but this appointment seems a bit odd to me. I've never even heard of Quique Setien, and looking at him he's a veteran coach who has had his biggest success recently, but that success amounts to getting small clubs to La Liga midtable.
On the surface, it looks like the equivalent of Man City sacking Pep and bringing in Sean Dyche to replace him.
Or is it simply a case of going for the best available coach who plays Cruyffball?
