McColl was part of a consortium which tried to buy the Ibrox club from liquidators BDO back in 2012.
In an interview with author and entrepreneur Rob Moore, quoted by the Glasgow Times, McColl has claimed FSG recently contacted him to see if he'd be interested in teaming up, taking over Rangers and using Moneyball techniques to resurrect their fortunes with John W. Henry said to be fascinated by the method.
“At no time in my mind was I going to buy it," he said.
“Although, I might think differently now because I was learning about this technique that was used in Moneyball.
"That is what's happening in Liverpool. It is the same technique they're using. You see them 22 points ahead of everybody else (Now 25 points) using this technique. So that's a thought.
“In fact, we were approached recently to see if we were interested in looking at it again. The people who have invested in Liverpool would be interested in looking at it with us and applying the same techniques.
“Not that I'll ever do it, but it's nice to think about them being 22 points ahead of Celtic."
