The former Sheffield United chief executive is leading the consortium in place to buy the stricken club, who have been in the hands of administrators Duff and Phelps since February.
He hopes creditors will vote in favour of a Company Voluntary Arrangement at a meeting next Thursday and that Rangers can then look to the future again.
Green says he has held budgets talks with manager Ally McCoist and former Italy and AC Milan star Gattuso - who played for the Light Blues between 1997 and 1998 - could be an option.
He told Rangers' official website: "The SPL can't register any players because we are in administration and the SFA and the club have been in a very public dispute for some time.
"However, the manager has identified a number of people from a playing point of view he would be interested in.
"Gattuso himself came out publicly and said he would love to join Rangers and, after the illustrious career he has had in Milan, that's great.
"His agent came over and we met with him to explain the difficulties surrounding the club. To me, it's a massive positive he wants to come.
"It's an endorsement that the world's top players would still like to come and play for this club.
"The manager actually played with Gattuso years ago when he was here at the club in the late 1990s.
"From my point of view as CEO, we've sat with Ally and arranged a budget with him and should we be allowed to sign players, he will be able to do so."
Meanwhile, Green has told Rangers fans he will not "abuse" their money and insists he has no plans to use cash from season ticket sales to fund his takeover.
Ibrox director Dave King has urged fans to reject the CVA, while calling on supporters not to renew their season tickets until Green reveals the details of his plans.
Craig Whyte completed his own takeover of Sir David Murray's majority shareholding last May with money from the sale of future season ticket income to investment firm Ticketus.
Green said: "On the basis the receiver is already holding cash and we haven't put the season tickets up for sale yet, I struggle to see how I can use season ticket money to buy the club.
"The season ticket renewal letters are actually going out today (Friday) and I have already deposited money with the administrator to buy the club.
"We have provided the money to buy the club and we have documented the fact we are going to raise another £20-30million on top of that.
"The season ticket money is crucial. The very suggestion we would be using it to buy the club is ridiculously untrue.
"The more season tickets any club sells, the more that can be invested back into the club and into players.
"If we are looking and speaking to the real, true Rangers fans, I'd say to them if there was ever a time to support the club it is now.
"They will know for the first time in many, many years that their money will not be abused the way it was before."
