In principle, I don't object to it. The biggest problem in football is the gap between the haves and have nots. That's what makes leagues uncompetitive and keeps the same teams winning every year. That's what stops teams being able to afford to keep the great squad they've built even if they win the league.
However, as always, the devil is in the detail, and the football authorities have shown themselves completely incapable of dealing with things like this, from the shambles that is the profit and sustainability rules, to the great idea that is VAR ruined by the incompetence of those put in charge of it.
There's a fundamental problem of changeable wage bills. For example, last season our wage bills went up from £354m to £423m, largely as a result of bonuses paid out for winning the treble. In the current system, that's absolutely fine, because those bonuses are directly linked to the extra revenue the players have created by winning those competitions. But under this system, it doesn't work, because no matter how well our players do and how much extra revenue they bring in as a result, our treble-winning season is doing nothing to boost Southampton's revenue. You could end up in a situation where a club fails FFP because they won everything.
Just as a quick test case:
Southampton's TV revenue: £128 x 5 = £640m
City's outgoings: £423m wages, £145m amortization, £51m agent fees = £619m
And so you see that we're right on the edge. But the stupid thing is that we wouldn't know we were right on the edge until the end of the season when all of these bonuses were activated. But it's also worth mentioning that while we are on the edge, in our most expensive ever season, we're still operating within the proposed rules, which raises the question, what problem are you solving? If it doesn't force us and the other top teams to cut our spending and does nothing to redistribute funding to the lower teams, then what's the point of it? Other than to give some suits something to make themselves feel important?
