Leicester director of rugby Richard Cockerill has sympathised with rivals Northampton over the possible exits of Soane Tonga'uiha and Brian Mujati.
The prop duo are rumoured to have been offered big money moves to Racing Metro, who have already secured the services of Jamie Roberts.
And following Saints boss Jim Mallinder admitting that he cannot compete with the French spending, Cockerill added his own concerns about salaries.
"The salary cap has bitten Tigers over a number of years and, if the reports are correct, Northampton are going to lose two of the props that they have brought in, developed and made world-class," Cockerill told the Leicester Mercury.
"As much as Northampton are huge rivals, I think it is wrong that they are not allowed to compete in the market place for their players.
"Tonga'uiha came from Bedford and they have made him into what he is.
"Now they cannot afford to keep him because of the salary cap. That is harsh.
"It's a financial choice. Look at Alesana Tuilagi who has gone from us to Japan for a considerable amount of money.
"We didn't even try to compete with that because he would have taken up 25 per cent of our cap.
"For someone like Geoff Parling, who is also out of contract, he has come from Newcastle and now he is starting for England.
"He will get offers bigger than ours, so it will be down to the good will of the player to say he likes playing for you, that he is really happy here trying to win something and that he will take 25 per cent less than he could get somewhere else."
