It depends what you mean as high-level. Conference Premier football is full of clubs paying silly money to chase their dreams. My team, Stafford Rangers, were promoted and nearly paid the ultimate price as football at that level was unsustainable. Unfortunaely, as you drop down, their are many clubs struggling to make ends meet. In the Conference North there are 5 or 6 clubs with playing budgets of £1700 per week or less. The rest vary upwards to a staggering £10,000+ per week paid out by Fleetwood Town.
Stafford have cut their cloth to survive and it has meant that the higher paid, higher profile players have had to leave. Only one player is contracted which has meant the vultures circling from time to time and stealing the best talent. However, this is a small price to pay should the club survive, which I believe firmly that it will. A number of clubs will go the wall either before the close of the season or during the summer and hopefully, this will force clubs into re-evaluating their position. Footballers at this level now need to understand the days of big contracts are gone. Get back to playing for the love of the game.
