Don't be bloody pathetic.
The point is, most people at the very top of football aren't there because they're a genius, they were ex-players who got a foot in the door at a top club.
There's plenty of people in the game who are just as knowledgeable, they just aren't at the top clubs and may never be.
Some of the so called 'top managers' make some truly crazy decisions sometimes and yes the fans CAN see those lousy decisions being made.
Nobody's saying Guardiola isn't any good, but he's not a God, and if Manchester City is the toughest task he's faced, that should tell you something.
