None of that 1st paragraph is true - who do you think allowed this to happen in the first place? And who do you think will be turning blind eyes to everything as Newcastle morph into an uber team in record time? FFP doesn't mean anything, City had the growing pains and 'punishments' of turning that around and Newcastle already have a blueprint to follow learning from other state/oil clubs.
A cull can happen at the same time as players are brought in, it's a secondary matter with a knock on effect that makes it look justified that all the players who are currently there on their old contracts getting no playing time, will gladly accept the pay offs to leave. The rotation of players coming in to out will be spectacular and all of it will look 'reasonable' if you don't delve deeper than the surface level - we ourselves have a bloated squad we're not doing much about as we look to bring players in and get some out; loans at first, then turfing out.
Their academy will also get a massive boost over the next couple of years and those elite players will be ready to enter the fray in 2-3 years themselves. It'll be players coming in from all angles and make them a 'proper' squad in super short time - you cannot use normal club parameters for a club completely removed from them; you can barely even use state/oil clubs as Newcastle's wealth dwarfs literally all of them, combined. It would actually be gross, gross incompetence for them not to hasten the process.
I admire the optimism you have regarding the traditional clubs, but it's already been shown to be utterly meaningless as City moonwalk across the league amassing points totals that kind of squad should accumulate. All it means for the clubs you mention is one less place to vie for, and for each of them to pray it's not them who get scorched by Newcastle's comet-like ascension.
re. 'Robinho' what you're doing is layer tracing City's growth from a time past, when going to clubs like them was fraught with danger and the pay cheque was literally everything. These days, it's all aboard a wild adventure for a player, and a 'Robinho' will have a lot less apprehension about joining such a side knowing full well he'll be part of an armada soon enough. Stating again, Newcastle can fine tune City's model and not make the mistakes they did, plus what I've said here applies to managers as readily as players, as they know they're going to the richest club on earth, with wealth that is greater than all of football's other sides, combined. (
)Being the highest paid manager on the planet, getting the players brought in that you want and autonomy at a level rarely seen at top clubs; it's a dream within a dream. If Conte was announced for next season (should they stay up), I wouldn't bat an eyelid.
