Financial problems increase pressure on wages
Many English Premier League clubs lost money last year on top of mounting debts, and two British clubs were forced into administration last month - Scottish champions Rangers and English Championship team Portsmouth.
Yet wages paid by Premier League clubs grew faster than their revenue for the last two years, and now make up an all-time high of 68 percent of club earnings, according to business services group Deloitte.
Britons are facing years of austerity and rising unemployment, fuelling a popular backlash over the levels of pay for senior bankers. Now footballers are stretching the loyalty of supporters.
"For people like me working in the public sector under a pay freeze, it's a kick in the teeth," Arsenal fan Paul Coleman, 24, told Reuters, speaking minutes after his club won a thrilling victory over North London rivals, Tottenham Hotspur.
The average pay earned by Premier League players is 25,000 pounds a week, the rough equivalent of what an average British worker earns in a year.
"When transfer time comes round and you hear about players wanting to leave because they're not being paid enough, but they're on 100 grand [thousand] a week," fellow fan Chris Walsh said.
"You could buy a house each week. It just makes you sick."
Both hold Arsenal season tickets which went up in price by 6.5 percent last year.
PAYING FOR RESULTS
Football administrators - like their counterparts in the City of London financial district - stress that clubs have to compete with big European rivals in the wage stakes.
"No football club is out there paying unnecessarily high wages. They pay the least amount they can to get the best possible players," said English Premier League spokesman Dan Johnson.
Restraint is not helped by evidence that sporting success comes at a price. According to Deloitte figures, there is a strong link between how much a club spends on wages and how high it ranks in the Premier League.
New Financial Fair Play from European football's ruling body UEFA aim to break that connection.
The rules, coming into full force in 2013, oblige clubs to stop posting repeated losses and settle their debts on time "to protect the long-term viability of European club football."
Wage inflation is also a problem in the Spanish league, where Real Madrid and FC Barcelona, the world's top earning sports clubs, together earn more than all the other clubs in the league combined.
Salaries at the top two clubs make up 51 percent of their revenue while the other clubs pay 69 percent on average, suggesting they are overstretching their budgets to compete.
By further comparison, the National Basketball Associaton (NBA) in the United States underwent a bitter pay dispute last year. NBA players are paid through a revenue sharing agreement and had their wages cut to 51.15 percent from 57 percent of earnings after owners imposed a lockout blocking players from using facilities.
PRESSURE TO CHANGE
In Britain, wealthy foreign owners have pumped hundreds of millions into some clubs, allowing them to buy players at uncapped costs and bidding up wages.
Players across Europe have also cashed in after the 1995 Bosman ruling which allowed them to move clubs for free when their contracts expire. Teams responded by offering top players longer and more lucrative contracts to ensure that they retained their prize assets.
But the industry is under increasing pressure to change.
Everton manager David Moyes this week called for everyone in the Premier League to take a 20 percent pay cut, to make the game more affordable for fans.
