Any Rangers player who tries to force a move away from the 'newco' club could face legal action, chief executive Charles Green has warned.
Green, the leader of the consortium which recently purchased the business and assets for £5.5million, is due to meet PFA Scotland representatives on Monday and said the transfer of player contracts to newco Rangers had already taken place. Midfielder Rhys McCabe has reportedly lodged an official objection and Sone Aluko is also reported to be unhappy.
Rangers CEO Green said: "We are meeting the PFA Scotland and their legal advisers on Monday with a view to allaying players' concerns about the transfer of contracts, so the timing of these announcements by players is hard to understand."
He continued: "The transfer of contracts has already happened and the club's clear legal advice is that players' purported objection is ineffective.
"Rangers would like to make it abundantly clear to players, agents and the chairmen and managers of other football clubs that we will take whatever steps necessary to challenge what we regard as a breach of contract to protect the interests of our club."
Rangers were forced into administration over an unpaid tax bill in February, and failure to secure a Company Voluntary Arrangement (CVA) in order to exit administration consigned the club to liquidation last week.
The new regime faces a battle to see newco Rangers granted entry into the Scottish Premier League and will face a vote by all 12 top-flight clubs on July 4, with Hearts and Dundee United having already indicated they will reject Rangers' bid.
Manager Ally McCoist wants the players to be open about their plans and called on them to let the club's fans know what is happening.
McCoist, in a statement jointly released with Green, said: "It has been reported that a couple of players have indicated they want to challenge the transfer of their contracts. This is news to me and no player has spoken to me about it.
"At all times during my first year as manager I strived to show players respect and in return would have hoped they would have shown me, and more importantly the club, respect by notifying us of their intentions before making it known elsewhere."
