It's been mentioned a good few times, but it has to spread further than England. We'll just lose the good players to countries that can pay more. I'd back it 100% if that were the case.
But, at the same time, would we still not lose everyone? If an English and a Spanish club both offer the maximum to a player, would there be enough of a difference tax-wise that they'll consider it a much better option to move to Spain?
