Given City's financial status and FFP workarounds, my initial impression would be that they suggest to players to hand in a transfer request, and agree to cover the loss of loyalty bonus, and then find a way to make the payment off the books. Call me cynical, but I think its more plausible than them being fiscally responsible, savvy negotiators who manage to seal deals for less than the going rate. Its not like the money is significant for them, and every club they are dealing with know that City can afford to pay whatever they need to.
