One thing to remember is that an lot of the big money is based on the sale of Stones, this has given Everton money to pay Palace which they have given to Liverpool. All big money deals but all dependant on one sale. Yes it has pushed up what clubs are asking for but in reality not many clubs are spending more than they are bringing in in transfers. We have not had any big money sales so no real money to spend.
As far as the TV money goes I thought that this comes in over the season so it is not available just now.
Works a year behind so this window club have received last years massive rise. Next season it will be a little bit more as now the massive increase has already arrived, the following few years the rise is more steady and gradual.
