Rangers would look to the influence of the All Blacks, baseball, basketball, American football and ice hockey if they were to search for a new manager, according to future Ibrox investor Paraag Marathe.
The Leeds United chairman and San Francisco 49ers chief is at the centre of an ambitious move to transform Rangers by leading a takeover.
Under pressure boss Philippe Clement received a vote of confidence from Ibrox chief executive Patrick Stewart this week.
But his position would surely come under further scrutiny if the American investors got their takeover over the line.
And, before appointing current Leeds boss Daniel Farke in July 2023 - who has guided them to the top of the English Championship this season - Elland Road chairman Marathe revealed the unusual influences he uses to pick a manager.
He said: "We looked at what kind of head coach we need, what kind of values he espouses and I did a bunch of research looking at clubs across the world.
"Not just in American football, but baseball, basketball and hockey and the All Blacks, everyone.
"I looked at the common trends and the first, most important, ingredient to changing a team’s fortunes is rebooting the culture, resetting the culture.
"You need to reset the culture and that means everybody, every single individual is responsible for that.
"It’s set, most of the time, by the head coach, not set by your owner because your head coach is responsible for the pitch or the field or the ice or the floor or the court.
"It’s set by that person and every single person in the organisation is responsible and accountable to being a part of that.
“If nothing else, it’s about a culture reset that has to happen for the club to be able to turn its fortunes around.”

And he stressed how he will never be rushed into a quick appointment after recalling the criticism he received for a delay in appointing a head coach to the San Francisco 49ers previously.
He said: "We spent 31 days interviewing 23 different head coach candidates and tried to stay true to our process and what we were trying to do and what we were trying to accomplish.
"We took some flak for it because other people were hiring their coaches and we were trying to tread patiently and stay true to our process.
"But it ended up working out well for us because we focused on culture, we focused on leadership. We didn’t necessarily ask specific, tactical questions on how they construct their practices.
"We didn’t ask those questions. We asked about true leadership and how they’re going to set the vision and culture for the team."
