Rob, I read about the contractual issue before, and it's hard to see how the football clubs have a case against it. It's certainly going to be interesting to follow! It seems fair that each player should be available for the value of the rest of their contract, so if the most any of our players are on is £40k p/w, on a 4 year contract, the most we could ever make is £8.3m. At the top end, that would mean if you've just given Suarez a £200k p/w, 4 year contract, he'd still be available for £32m, which is much less than Liverpool would want.
I disagree with you that it would reduce the cost to supporters though. Rich owners are still going to want to splash the cash, and to hold onto their best players, so you'd expect player wages to increase substantially at the top end to make them harder to move on. That means though that all the money is going to the players, effectively taking it out of football. That means that an increased amount of turnover is going to be spent on player wages, so things like ground improvements are going to get harder to finance. As a small club, you'll no longer be able to sell your wonderkid to the big boys and use the several million you get to finance a new stand, they might be lucky to get £100k. It'll all be passed on to the supporters instead.
How to circumvent it? Not sure. I was wondering if it could be achieved with central FIFA contracts, but I can't figure out how it'd work.
