Vidmar believes that some of the fees being paid for players recently is more than the young league can withstand.
"Some of the money that is being thrown out at players is a little bit ridiculous at this point in time," he said.
"Most A-League clubs are trying to find their feet still after four years and some of the money being thrown out there to players is ludicrous in my opinion.
"We've tried to make some big plays for some big players, Aussie boys who are playing overseas and Aussies who are playing in the A-League currently, and it is just not enough money for them.
"We think it is fair value for the players that we've offered those contracts to and they have decided to go elsewhere."
