These newer, more draconian financial rules are going to be a wake up call for a lot of players agents. Given the biggest spend by far at clubs is on players and fees they are the ones who are going to take the biggest hits.
My guess is that pressure on wages will be downwards at all but the PL teams and also that sides will run with smaller squads. This equates to lower wages and less jobs.
We might find that as we approach the start of the season wage demands fall and as we go past the end of the window free agents end up accepting a lot less money or dont find a club at all.
