Primarily I'd guess because they don't like the answer and they know the fans of the other clubs won't like being told either. This isn't a one season phenomenon, it hasn't happened just since Pep arrived, it isn't even a five year phenomenon. It's been in operation since the day the Sheik took over. It's happened and been managed with military precision by executives with outstanding business acumen all based on recruiting the best people, giving them the best environment in which to operate and then allowing them to do their job. This has been happening under the noses of Ed Woodward, Henry, Levy, Kronke, Laurence and every other CEO and, rather than step up and improve their own clubs from the inside, they've sought to derail City from the outside. Sheik Mansour is happy to invest billions, confident that his investment will make billions (which it has). The likes of FSG, Kronke and the Glazers still want 'the billions', they just want them without the investment or the hard work that goes with it.
