Rangers' administrators have received "several expressions of interest from parties not connected to the club" since taking over the running of the business.
Paul Clark, of administrators Duff and Phelps, made the announcement during a press conference at the club's Ibrox stadium.
The Glasgow-based club appointed Duff and Phelps after a petition was lodged by HM Revenue and Customs (HMRC) at the Court of Session in Edinburgh to have one appointed for them.
Rangers FC was forced into administration over an unpaid tax bill of £9 million accrued since Craig Whyte's takeover last May.
Mr Clark said: "As administrators we have to look at all other expressions of interest in the club and to date we have received several expressions of interest from parties not connected to the club. These will be subject to ongoing discussions and examined in the forthcoming days."
The club was handed an automatic 10-point deduction by the Scottish Premier League (SPL) because of the administration move. Rangers, now 14 points behind SPL leaders Celtic as a result of the decision, are also awaiting the verdict of a tax tribunal which could cost it £75 million.
Mr Clark said he had spoken to team manager Ally McCoist and his squad but was unable to confirm if any club staff, including the players, would be made redundant.
He said: "I told them a review of staffing, including playing staff, would be necessary as part of the process and that it would be next week at least prior to any decisions being taken in this area.
"I'm not going to speculate what this review will entail. I am delighted to confirm that we will be making the February payroll obligations in full."
He added: "Looking to the future we are hopeful that a Company Voluntary Arrangement (CVA) can be achieved and these are measures that are put in place and deal with all of the club's liabilities. As a result of our preliminary assessment we are wholly confident that Rangers will continue as a football club."
