Sale Sharks owner Brian Kennedy believes Rangers are in good hands after rival Bill Miller was named preferred bidder to take over the club.
Duff and Phelps opted for an £11.2million offer from the American tycoon over a bid from former Ibrox director Paul Murray's Blue Knights, which was backed by Kennedy.
Miller - whose plan is to create an "incubator" company while administrators aim to take the club out of administration via a Company Voluntary Agreement (CVA) - hopes to complete his transaction by the end of the season.
Kennedy told the Scottish Sun: "There's no sour grapes on my part, none at all. My mission and aim was only to ensure that Rangers were rescued and spared from going into liquidation, that the club's history and tradition remained intact.
"From that point of view, it's very much mission accomplished.
"Mr Miller is a very credible businessman and he's ticked all the boxes from an administrator's point of view. He has already invested an awful lot of his time, money and effort into his bid for the football club.
"Yes, he has endured some very difficult times, but in my experience, the hard times only make you stronger.Rangers are now in good hands and ready to move forward.
"I believe Mr Miller to be a very good man. I would like to wish him, the team and the club every success for the future."
