All of this wage speculation is just that, though. Speculation.
The initial reports about Bale's contract, for example, had it down as a rise to £75k + performance bonuses.

Adebayor's wages were being dealt with via a one-off signing on fee, to cover the difference between what he'll receive and what he would've got had he remained for the final year of his deal at City.
The Sigurdsson suggestion came via a rather bitter Brendan Rodgers, who's since continued to moan about it.
I wouldn't be surprised if we were just continuing on with a similar wage structure, but the upper limit has increased a bit due to off-field success.
The more we earn, the more we can afford to pay.
