Everton boss David Moyes has described the transfer policies adopted by West Ham and Portsmouth as "a danger to football".
All the attention may be on Kaka's potential £100million-plus move to Manchester City, but Moyes believes it is clubs offering big wages that have upset the balance of the market.
He told the Sunday Express: "I think what happened at Portsmouth and West Ham in recent times was a danger to football.
"They bought players and gave them big wages. That made it difficult for clubs like Everton because we would try to get similar players but they blew us out with higher wages, far more than Everton could afford.
"It upset the whole market. Now they are backing off and selling players because they paid them higher wages than maybe they should have.
"In truth, the people who went into those clubs are now either one down, or bankrupt, or can't afford to pay the wages.
"Now Portsmouth might say, 'We had our day in the sun. We won the FA Cup and we don't really care'.
"But I think those sort of clubs are the ones which have disrupted the wages in the Premier League."Reuse content
