Potential Rangers owner Brian Kennedy was at Ibrox on Wednesday as the club's administrators continued with their attempts to sell the financially stricken Scottish outfit.
Kennedy, who owns Premiership rugby union team Sale Sharks, and former Ibrox director Paul Murray's consortium are the only confirmed bidders with an American consortium also reported to be among the interested parties for Rangers, who were forced into administration last month.
Rangers manager Ally McCoist was also at the stadium on Wednesday as the Scottish champions attempt to resolve their off-field issues, while trying to ensure a return to winning ways on the park.
They suffered a third defeat in four games since going into administration when they lost against Dundee United on Saturday.
The loss at Tannadice means arch rivals Celtic could clinch the Premier League title at Ibrox on Sunday if Motherwell drop points to Kilmarnock on Saturday.
However, striker David Healy believes Rangers must take confidence from their last home meeting with the Hoops, which ended in a 4-2 victory for McCoist's men in September.
"It's going to be a tough challenge and it's always a big game," Healy said.
"I know everybody here is looking forward to it and Celtic will be looking to bounce back after their disappointment in the Scottish League Cup final.
"We lost at Dundee United and Celtic lost in the cup final so we'll both want to bounce back - and there's everything that goes with the Old Firm in terms of the passion and Celtic might have the chance to win the league.
"But we beat them earlier in the season, which was an incredible game and performance.
"The atmosphere that day was electric so I know there is going to be a huge, passionate support for both sides on Sunday and everybody is going to be looking forward to it."
