Arsenal boss Arsene Wenger wants to see clubs that sign players on-loan to cover their wages in full.
Wenger is particularly unimpressed by Manchester City subsidising the wages of Craig Bellamy at Cardiff City.
"They [Man City] can afford the wages of the players without playing them," he told arsenal.com.
"The problem is when you loan your players out and you pay half of their wages. Is that right or wrong? Is that legal or not legal?
"When you say 'the wages are too high' but what do you do? I have the same problem when I loan a player out to the Championship, if the player's wages are too high.
"What has happened recently is that the financial potential of the Championship clubs has gone down, the Division One clubs has gone down, most of those clubs have problems to survive so they cannot pay the wages any more for players who go - even for players who go there to sign a contract."
