What really grinds my gears about your original post is the sheer arrogance behind the tone of 'we don't really need this player, but we can get him, and we so we have.' Of course City's owners will never be insolvent. Who might imagine such a scenario, their power, financial, political etc, is beyond anyone's reach. In a sense, my beef is personal to the Villa, since this is the fourth time since coming into their oil riches that Manchester City have been able to take unto themselves our best player and captain (Jack Grealish following in the footsteps of Fabian Delph, James Milner and Gareth Barry). Your original post might suggest that Grealish may spend as much time warming the bench as did the other three, which remains to be seen. Be that as it may, my concern is not in the main about the Villa, since the signings we have already made these last few weeks (Buendia, Bailey and Ings) means we have a far stronger and more balanced squad of players than we have had for some time; and so I don't worry about Grealish leaving, from a purely parochial perspective.
The future of English football generally is perhaps more of a concern, when a club like Manchester City is free to act in the way it does on the back of its foreign oil revenues (Harry Kane of course being the next man in line), and to the delight it would seem of its new found fan base.
