Why? Cardiff just bought Adam Le Fondre for 1m, there are good players out there and no need to spend bucket loads of cash.
It's not always about the fee - it's more often about the wage and the contract length. If (guess) Le Fondre wants £20k/w and a three year deal, that would be a £3.1m commitment just in wages (before agent's fees). So often you can almost disregard the fee in cases like that.
