You don't duck out things that easily I'm afraid. It also comes down to how much money you have available to use. And in City's case huge chunks of money are unearned - simply gifted from your sugar-daddy.
Case in point: Spurs have funded their new stadium from their own pockets - which in large part is why our net spend on transfers over the last 10 years has been just £15m.
In contrast, City don't even own their stadium and have net-spent £563m on transfers in the last 5 years alone.
To put it another way, in the last 5 years City have net-spent on transfers more than 37 times what Spurs have spent in 10 years. And this doesn't include spending on wages.
No you haven't. Your stadium investment is being financed with a considerable chunk of debt. Presumably your owner, and the lenders, believe additional revenue derived from the new stadium will be sufficient to repay the debt. Once the debt is repaid, your owner may decide that the additional stadium revenues could be used to finance player acquisition and drive improved on-pitch performance, which would provide a return on investment to your owner through the increased value of the club. This is generally the argument made for stadium investment, although I note that Arsenal originally stated that this was going to be their approach, but they haven't actually implemented it yet.
City's investment, on the other hand, has been largely focused on player acquisition (although there was some stadium investment for the South Stand expansion) and has been financed by our owner's equity. Presumably our owner believed that player acquisition would drive improved on-pitch performance, which would provide a return on investment to our owner through the increased value of the club. Our owner has already been proven correct.
So if both Spurs' and City's strategies are based around improving on-pitch performance and increasing the value of our respective clubs, why is Spurs' strategy acceptable, but City's strategy not acceptable? I can think of a few potential answers:
1) If the issue is debt vs. equity, then presumably it would have been acceptable if our owner had loaded debt on to the club to finance player acquisition instead of providing equity? Your post suggests that you would consider this to be "out the club's own pockets." This would be strange to argue for though, as it would place the club at far greater risk of financial issues if the investment in player acquisition did not lead to improved on-pitch performance and increased revenues, as the club may struggle to repay debt to the owner and the owner wouldn't receive a return on investment through increased value of the club. Isn't FFP supposed to be all about protecting clubs from financial risks?
2) If the issue is the scale of financing, then the question is where do we draw the line? Spurs' debt investment of let's say £400m is fine, but City's equity investment of £1.3bn is not fine. So would you have been happy for City's owners to provide £400m equity investment for player acquisition then?
3) If the issue is investment in a stadium rather than players, then FFP would agree with you given that stadium investment is not included in FFP calculations. However, there's no logical need for City's owners to build a new stadium. It seems strange for football's governing bodies to effectively be telling owners where they can and cannot invest, particularly as for City's owner the return on investment would be potentially much higher for player acquisition than stadium development in terms of its impact on the value of the club.
4) If the issue is nothing to do with investment at all, but is actually City's owner, his position in the UAE government, and human rights issues in the UAE, then that's absolutely fine, everything above is irrelevant. But obviously there was nothing in the Fit and Proper Person regulations that prevented City's owner taking over, and there still isn't, which suggests that football's governing bodies have no issue with City's owner.
Or maybe it's a mix of all four. Sometimes it's hard to keep up with arguments against City's owner and City's investment strategy.
