Pep Guardiola told Manchester City fans who doubted his various tactical experiments over the years that he makes his decisions using the wealth of information available to him that supporters simply don't see.
In short - and phrased respectfully - the manager knows more than the rest of us. Few can argue with that, and Guardiola has earned the right to tinker and be called a genius when it works.
One thing Guardiola openly admitted to not knowing, however, was how the World Cup would affect City. Two months on from the World Cup final, and only now can Guardiola really say all of his City players are 'back'. Now he knows everything.
